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).
Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc on
an Agilent/HP 4284A LCR-meter or equivalent.
SRF measured using Agilent/HP 4191A or equil-
valent.
DC current that causes the specified inductance
drop from its value without current..
Current that causes the specified temperature
rise from 25°C ambient.
