1. When ordering, please specify termination code:
RFS1412-105KE
Termination: E = Tin-silver over tin over copper over steel.
Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37).
2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR-meter or equivalent.
3. SRF measured using Agilent/HP 4191A or equilvalent.
4. DC current that causes the specified inductance drop from its value without current..
5. Current that causes the specified temperature rise from 25°C ambient.
6. Electrical specifications at 25°C.
