REMINDERS FOR USING THESE PRODUCTS
Before using these products, be sure to request the delivery specifications.
SAFETY REMINDERS
Please pay sufficient attention to the warnings for safe designing when using these products.
REMINDERS
The storage period is less than 12 months. Be sure to follow the storage conditions (Temperature: 5 to 40°C, Humidity: 10 to 75% RH
or less).
If the storage period elapses, the soldering of the terminal electrodes may deteriorate.
Do not use or store in locations where there are conditions such as gas corrosion (salt, acid, alkali, etc.).
Before soldering, be sure to preheat components.
The preheating temperature should be set so that the temperature difference between the solder temperature and chip temperature
does not exceed 150°C.
Soldering corrections after mounting should be within the range of the conditions determined in the specifications.
If overheated, a short circuit, performance deterioration, or lifespan shortening may occur.
When embedding a printed circuit board where a chip is mounted to a set, be sure that residual stress is not given to the chip due to
the overall distortion of the printed circuit board and partial distortion such as at screw tightening portions.
Self heating (temperature increase) occurs when the power is turned ON, so the tolerance should be sufficient for the set thermal
design.
Carefully lay out the coil for the circuit board design of the non-magnetic shield type.
A malfunction may occur due to magnetic interference.
Use a wrist band to discharge static electricity in your body through the grounding wire.
Do not expose the products to magnets or magnetic fields.
Do not use for a purpose outside of the contents regulated in the delivery specifications.
The products listed on this catalog are intended for use in general electronic equipment (AV equipment, telecommunications
equipment, home appliances, amusement equipment, computer equipment, personal equipment, office equipment, measurement
equipment, industrial robots) under a normal operation and use condition.
The products are not designed or warranted to meet the requirements of the applications listed below, whose performance and/or
quality require a more stringent level of safety or reliability, or whose failure, malfunction or trouble could cause serious damage to
society, person or property.
If you intend to use the products in the applications listed below or if you have special requirements exceeding the range or conditions
set forth in the each catalog, please contact us.

Overview of MLP2520 type
FEATURES
A low-loss magnetic material is used so that a low-loss inductor for the power supply circuit can be achieved.
In addition to the inductance value, product types with various features are available so that they can be compatible with different
usages.
W Type: Products with low DC resistance and large current.
H Type: This product uses a low-loss material and has low DC resistance.
* Optimal for when heavy load power efficiency is important.
V Type: As with the H type, this product with a low-loss magnetic material and that has good DC superimposition type characteristics.
* Optimal for when light load power efficiency is important.
S Type: STD product lineup that includes a wide L value and various sizes.
APPLICATION
Smart phones, tablet terminals, digital cameras, video cameras, HDDs, power supply modules, etc.
