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.
