1. When ordering, please specify termination and packaging codes:
Typical Circuits
CSTX-125LC
Termination: L = RoHS compliant tin-silver over tin over nickel over phos
bronze (pins 1 – 6); RoHS compliant tin-silver over tin
over nickel over copper (pins 7 – 8)
CST1

Special order: S = non-RoHS tin-lead (63/37) over tin
over nickel over phos bronze (pins 1 – 6); nonRoHS tin-
lead over gold over nickel over copper (pins 7 – 8).

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.

2. Inductance measured between secondary pins at 100 kHz, 0.1 Vrms.
3. Primary current of 10 A causes approximately 25°C temperature rise
from 25°C ambient. Higher current causes a greater temperature rise
(see Temperature Rise vs Current curve).
4. Terminating resistance (RT) value is based on 1 Volt output with
10 Amps flowing through the primary. Varying terminating resistance
increases or decreases output Voltage/Ampere according to the fol-
lowing equation: RT (Ohms) = Vout × Nsec/Iin.
