## **GENERAL SPECIFICATIONS** 

**(1) Inductance** 

Measured at 100kHz, 100mA 

Rated current will cause the coil temperature rise ΔT of 40K 

**(2) Rated Current** _IR measured with the inductor soldered in a single-layer PCB. Copper layer thickness 35µm Cu / PCB size 30x50mm. Temperature behavior dependent on circuit design, PCB layout, proximity to other components, and trace dimensions and thickness._ 

|**(3) Saturation Current25°C**|Saturation current will cause L to drop from 30% at 25°C ambient temperature|
|---|---|
|**(4) Saturation Current100°C**|Saturation current will cause L to drop from 30% at 100°C ambient temperature|
|**Temperature Test Condition**|Electrical specifications measured at 25°C, 35% RH if not given differently|
|**Operating Condition**|Operating temperature: -40°C to +125°C (including temp rise)<br>Should not exceed +125°C under worst-case operation conditions|
|**Storage Condition**|Tape and Reel packaging: -10°C to +40°C<br>Humidity: <50% RH|
