1. When ordering, please specify
termination
and
packaging
codes:
CJ5143-ALC
Termination: L
= RoHS compliant tin-silver (96.5/3.5) over copper.
Special order, added cost:
T
= RoHS tin-silver-copper (95.5/4/0.5) over copper
or
S
= non-RoHS tin-lead (63/37) over copper.
Packaging: C
= 7″ machine-ready reel. EIA-481 embossed plastic
tape (250 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 (1000 parts per
full reel).
2. Inductance measured at 100 kHz, 0.1 Vrms.
3. Peak primary current drawn at minimum input voltage.
4. Leakage inductance is for the primary winding with the secondary
winding shorted.
5. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
