1. When ordering, please specify packaging code:
EPL7242-47±MEC
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic tape (300 parts per full reel).
Irms Testing
Irms testing was performed on
0.75 inch wide × 0.25 inch thick
copper traces in still air.
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.
Temperature rise is highly depen-
dent on many factors including
pcb land pattern, trace size, and
proximity to other components.
Therefore temperature rise
should be verified in application
conditions.
D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked
(1000 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 or equivalent.
5. 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.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
