1. When ordering, please specify
termination
and
packaging
codes:
EPL2010-103MLC
Termination: L
= RoHS compliant tin-silver over gold over nickel over
silver.
Special order:
T
= RoHS tin-silver-copper (95.5/4/0.5)
or
S
= non-RoHS tin-lead (63/37).
Packaging: C
= 7″ machine-ready reel. EIA-481 embossed plastic
tape (2000 parts per full reel).
B
= Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge), use
code letter C instead.
D
= 13″ machine-ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (7500 parts per
full reel).
Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.
DCR measured on a micro-ohmmeter.
SRF measured using Agilent/HP 4395A network analyzer or equivalent.
DC current at which the inductance drops the specified amount from its
value without current.
6. Current that causes the specified temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
See Qualification Standards section for environmental and test data.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
Specifications subject to change without notice.
Please check our website for latest information.
