1. When ordering, please specify
packaging
code:
EPL3314-473MEC
Packaging: C
= 7″ machine-ready reel. EIA-481 embossed plastic tape (2000 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 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 which the inductance drops from its value without current.
6. Current that causes the specified temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.

Small surface blemishes are not unusual and do not adversely affect performance.
Wire may be visible inside the voids.
Acceptable void sizes:
Top: 0.01 in / 0,254 mm × 0.01 in / 0,254 mm
Sides: 0.02 in / 0,5 mm × 0.047 in / 1,2 mm
Note: All marked parts have three dots. Black dot, used only on -102 and -103 as
second significant digit, may be very difficult to see.
