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 25C ambient. 6. Electrical specifications at 25C.
