1. When ordering, please specify

packaging code:

CST7030-150LC

Packaging: C = 7

″ machine-ready reel. EIA-481 embossed plastic

tape (600 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 (2500 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 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).

flowing through the primary. Varying terminating resistance increases or

decreases output Voltage/Ampere according to the following equation:
