1. When ordering, please specify packaging code:
SCS-200LD
Packaging:D
=13″ machine-ready reel. EIA-481 embossed plastic
tape (200 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 10 kHz, 0.06 Vrms,
0 Adc.
3. Primary DCR is measured with the windings connected in parallel.
4. Maximum volt-time product is for the secondary, based on 2000 Gauss.
5. Primary current of 30 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).
6. Terminating resistance (RT) value is based on 1 Volt output with 30 Amps
flowing through the primary. Varying terminating resistance increases or
decreases output Voltage/Ampere according to the following equation:
RT = Vout × Nsec / Iin.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
