D1787-AL 33.0 0.0028 9.0 8.0 23.0
1 Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMD-D fixture in an Agilent/HP 4263B impedance analyzer or equivalent.
2 SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. Details
3 Isat: DC current at which inductance drops 20% (typ) from its value without current. Details
4 Irms: Current that causes a 40°C temperature rise from 25°C ambient. Details
5 Ambient temperature range: –40°C to +85°C with
6 Storage temperature range: Component: –40°C to +85°C
Packaging: –55°C to +80°C
7 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
8 Electrical specifications at 25°C.
See Qualification Standards for complete environmental and test data.
