1. When ordering, please specify packaging code:
CST4835-150EC
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (500 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 (2200 parts per full reel).
2. Inductance measured between secondary pins at 100 kHz, 0.1 Vrms,
0 Adc.
3. Maximum volt-time product is for the secondary, based on 2000 Gauss.
4. Primary current of 7 A causes less than 25°C temperature rise from
25°C ambient. Higher current causes a greater temperature rise (see
Temperature Rise vs Current curve).
5. Terminating resistance (RT) value is based on 1 Volt output with 7 Amps
flowing through the primary. Varying terminating resistance increases or
decreases output Voltage/Ampere according to the following equation:
RT = Vout × Nsec / Iin.
6 Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
