numbering system, Coilcraft is eliminating the need
for multiple packaging codes. When ordering, simply
change the last letter of your part number from B to C.
D =13″ machine-ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (2500 parts per
full reel).

2. Inductance measured between secondary pins at 100 kHz, 0.1 Vrms, 0 Adc.
3. For specific questions regarding frequency range, please contact us at
cst@coilcraft.com.
4. Volt-time product is for the secondary, between pin 1 and 2.
5. Primary current of 20 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 20 Amps
flowing through the primary. Varying terminating resistance increases or
decreases output Voltage/Ampere according to the following equation:
RT = Vout × Nsec/Iin.
