1. When ordering, please specify
termination
code:
RFB1010-183L
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 equivalent.
DC current at which the inductance drops 10% (typ) from its value without current.
Current that causes the specified temperature rise from 25°C ambient.
