1. When ordering, please specify termination code:
RFS1317-106L
Termination: L = 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 equil-
valent.
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.
