GENERAL SPECIFICATIONS
(1) Inductance
Measured at 100kHz, 100mA
Rated current will cause the coil temperature rise ΔT of 40K
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.
(2) Rated Current
(3) Saturation Current 25°C
(4) Saturation Current 100°C
Temperature Test Condition
Saturation current will cause L to drop from 30% at 25°C ambient temperature
Saturation current will cause L to drop from 30% at 100°C ambient temperature
Electrical specifications measured at 25°C, 35% RH if not given differently
Operating temperature: -40°C to +125°C (including temp rise)
Should not exceed +125°C under worst-case operation conditions
Tape and Reel packaging: -10°C to +40°C
Operating Condition
Storage Condition
Humidity: <50% RH
