1. When ordering, please specify termination and packaging codes:
EPL2014-103MLC
Termination:L = RoHS compliant tin-silver-copper over tin over nickel
Special order, added cost: 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).

2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.
3. DCR measured on a micro-ohmmeter.
4. SRF measured using Agilent/HP 4395A network analyzer or equivalent.
5. DC current at 25°C that causes the specified inductance drop from its
value without current. Click for temperature derating information.
6. Current that causes the specified temperature rise from 25°C ambient.
This information is for reference only and does not represent absolute
maximum ratings. Click for temperature derating information.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
