Measurement Condition:
Technical Guide:
1. Storage Conditions:
Temperature:
5 to 35ºC (40 to 95ºF).
Humidity:
25 – 60% relative humidity.
Term:
One year in poly-bag with desiccant. If parts are removed from the poly-bag,
they should be used immediately or resealed in the bag.
Environment:
Clean, dry environment, free of corrosive gases.
2. Application precautions:
Lead forming:
Forming is recommended at least 2mm of farther from the base of the lead.
Soldering:
Soldering is recommended at least 4mm or farther from the base of the lead.
3. Washing:
Carbon composition resistors are highly hygroscopic and changes in resistance value can occur if too much
moisture is absorbed. For this reason, it is recommended not to use water or water-soluble solvents to clean these
components. Alcohol or hydrocarbon solvents are recommended for rinsing.
4. Soldering Recommendations:
Note: The conditions shown below are for reference. Please perform a mounting evaluation to assure
compatibility.
a. Flow soldering (recommended profile for Sn and Sn/Pb solders).

RoHS Compliance
Stackpole Electronics has joined the worldwide effort to reduce the amount of lead in electronic components and to meet the various
regulatory requirements now prevalent, such as the European Union’s directive regarding “Restrictions on Hazardous Substances”
(RoHS 3). As part of this ongoing program, we periodically update this document with the status regarding the availability of our
compliant components. All our standard part numbers are compliant to EU Directive 2011/65/EU of the European Parliament as
amended by Directive (EU) 2015/863/EU as regards the list of restricted substances.

“Conflict Metals” Commitment
We at Stackpole Electronics, Inc. are joined with our industry in opposing the use of metals mined in the “conflict region” of the eastern
Democratic Republic of the Congo (DRC) in our products. Recognizing that the supply chain for metals used in the electronics industry
is very complex, we work closely with our own suppliers to verify to the extent possible that the materials and products we supply do
not contain metals sourced from this conflict region. As such, we are in compliance with the requirements of Dodd-Frank Act regarding
Conflict Minerals.
