• Install the following systems for a failsafe design to ensure safety if these products are to be used in equipment
where a defect in these products may cause the loss of human life or other significant damage, such as
damage to vehicles (automobile, train, vessel), traffic lights, medical equipment, aerospace equipment,
electric heating appliances, combustion/gas equipment, rotating equipment, and disaster/crime prevention
equipment.
✽ Systems equipped with a protection circuit and a protection device.
✽ Systems equipped with a redundant circuit or other system to prevent an unsafe status in the event of a single fault.
✽ Systems equipped with an arresting the spread of fire or preventing glitch.
Precautions for use
• These products are designed and manufactured for general and standard use in general elec tron ic equipment.
(e.g. AV equipment, home electric appliances, office equipment, information and communication equipment)
For applications in which special quality and reliability are required, or if the failure or malfunction of the
products may directly jeopardize life or cause threat of personal injury (such as for aircraft and aerospace
equipment, traffic and transport equipment, combustion equipment, medical equipment, accident prevention
and anti-theft devices, and safety equipment), please be sure to consult with our sales representative in
advance and to exchange product specifications which conform to such applications.
• These products are not intended for use in the following special conditions. Before using the products, carefully
check the effects on their quality and performance, and determine whether or not they can be used.
1. In liquid, such as water, oil, chemicals, or organic solvent.
2. In direct sunlight, outdoors, or in dust.
3. In salty air or air with a high concentration of corrosive gas, such as Cl2, H2S, NH3, SO2, or NOX .
4. Electric Static Discharge (ESD) Environment.
These components are sensitive to static electricity and can be damaged under static shock (ESD).
Please take measures to avoid any of these environments.
Smaller components are more sensitive to ESD environment.
5. Electromagnetic and Radioactive Environment.
Avoid any environment where strong electromagnetic waves and radiation exist.
6. In an environment where these products cause dew condensation.
7. Sealing or coating of these products or a printed circuit board on which these products are mounted, with
resin or other materials.
• These products generate Joule heat when energized. Carefully position these products so that their heat will
not affect the other components.
• Carefully position these products so that their temperatures will not exceed the category temperature range
due to the effects of neighboring heat-generating components. Do not mount or place heat-generating
components or inflammables, such as vinyl-coated wires, near these products.
• Note that non-cleaning solder, halogen-based highly active flux, or water-soluble flux may deteriorate the
performance or reliability of the products.
• Carefully select a flux cleaning agent for use after soldering. An unsuitable agent may deteriorate the
performance or reliability. In particular, when using water or a water-soluble cleaning agent, be careful not to
leave water residues. Otherwise, the insulation performance may be deteriorated.
• Do not apply flux to these products after soldering. The activity of flux may be a cause of failures in these
products.
• Refer to the recommended soldering conditions and set the soldering condition. High peak temperature or
long heating time may impair the performance or the reliability of these products.
• Recommended soldering condition is for the guideline for ensuring the basic characteristics of the products,
not for the stable soldering conditions. Conditions for proper soldering should be set up according to individual
conditions.
• Do not reuse any products after removal from mounting boards.
• Do not drop these products. If these products are dropped, do not use them. Such products may have
received mechanical or electrical damage.
• If any doubt or concern to the safety on these products arise, make sure to inform us immediately and
conduct technical examinations at your side.

Fixed Resistors
Precautions for storage
The performance of these products, including the solderability, is guaranteed for a year from the date of
arrival at your company, provided that they remain packed as they were when delivered and stored at
a temperature of 5 °C to 35 °C and a relative humidity of 45 % to 85 %.
Even within the above guarantee periods, do not store these products in the following conditions.
Otherwise, their electrical performance and/or solderability may be deteriorated, and the packaging
materials (e.g. taping materials) may be deformed or deteriorated, resulting in mounting failures.
1. In salty air or in air with a high concentration of corrosive gas, such as Cl2, H2S, NH3, SO2, or NOX .
2. In direct sunlight.
<Package markings>
Package markings include the product number, quantity, and country of origin.
In principle, the country of origin should be indicated in English.
AEC-Q200 Compliant
The products are tested based on all or part of the test conditions and methods defined in AEC-Q200.
Please consult with Panasonic for the details of the product specification and specific evaluation test results,
etc., and please review and approve Panasonic's product specification before ordering.

Surface Mount Resistors
Application Guidelines (Surface Mount Resistors)
The following are precautions for individual products. Please also refer to the common precautions for Fixed
Resistors in this catalog.
1. Take measures against mechanical stress during and after mounting of Surface Mount Resistors
(hereafter called the resistors) so as not to damage their electrodes and protective coatings.
Be careful not to misplace the resistors on the land patterns. Otherwise, solder bridging may occur.
2. Keep the rated power and ambient temperature within the specified derating curve.
Some circuit boards, wiring patterns, temperatures of heat generated by adjacent components, or
ambient temper a tures can become factors in the rise of the temperature of the resistors, regardless of
the level of power applied. Therefore, check the conditions before use and op timize them so as not to
damage the boards and peripheral components.
Make sure to contact us before using the resistors under special conditions.
3. If a transient load (heavy load in a short time) like a pulse is expected to be applied, check and evaluate
the operations of the resistors when installed in your products before use. Never exceed the rated power.
Otherwise, the performance and/or reliability of the resistors may be impaired.
4. Transient voltage
If there is a possibility that the transient phenomenon (significantly high voltage applied in a short time)
may occur or that a high voltage pulse may be applied, make sure to evaluate and check the
characteristics of resistors mounted on your product rather than only depending on the calculated power
limit or steady-state conditions.
5. If the resistors are to be used in high frequency circuits, carefully check the operation before use.
Such circuits change the electrical characteristics of the resistors.
6.Before using halogen-based or other high-activity flux, check the possible effects of the flux residues on the
performance and reliability of the resistors.
7. When soldering with a soldering iron, never touch the resistors'bodies with the tip of the soldering iron.
When using a soldering iron with a high temperature tip, finish soldering as quickly as possible
(within three seconds at 350 °C max.).
8. Mounting of the resistors with excessive or insufficient wetting amount of solder may affect the
connection reliability or the performance of the resistors. Carefully check the effects and apply a proper
amount of solder for use.
9. When the resistors' protective coatings are chipped, flawed, or removed, the characteristics of the
resistors may be impaired. Take special care not to apply mechanical shock during automatic mounting
or cause damage during handling of the boards with the resistors mounted.
10. Do not apply shock to the resistors or pinch them with a hard tool (e.g. pliers and tweezers). Otherwise,
the resistors' protective coatings and bodies may be chipped, affecting their performance.
11. Avoid excessive bending of printed circuit boards in order to protect the resistors from abnormal stress.
12. Do not immerse the resistors in solvent for a long time.
Before using solvent, carefully check the effects of immersion.
13. Do not apply excessive tension to the terminals.
