|---|---|
|(1) Inductance  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 Current 25°C|Saturation current will cause L to drop from 30% at 25°C ambient temperature|
|(4) Saturation Current 100°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 temperature: -40°C to +125°C (including temp rise)|
|Operating Condition|
|Should not exceed +125°C under worst-case operation conditions|
|Tape and Reel packaging: -10°C to +40°C|
|Storage Condition|
|Humidity: <50% RH|
