• All test data is referenced to 25°C ambient
• DC current (Idc) that will cause an approximate
△
T of 40℃
• DC current (Isat) that will cause Lo to drop approximately 20%
• Operating temperature Range: –40°C to +125°C
• The part temperature (ambient + temp rise) should not exceed125℃ under the worst operating conditions. Circuit design,
component placement, PWB trace size and thickness, airflow and other cooling provisions all affect the part temperature.
Part temperature should be verified in the end application.
■Packaging

Reminders
Please pay sufficient attention to the warnings for safe designing when using these products.
※
The storage period is less than 12 months. Be sure to follow the storage conditions (Temperature: 5 to 40°C,
Humidity:10 to 75% RHor 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 temperaturedoes 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.
※
Self heating (temperature increase) occurs when the power is turned ON, so the tolerance should be
sufficient for the set thermaldesign.
※
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.
