1. Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (250 parts per full reel). Quantities less than full reel available: in
tape (not machine ready) or with leader and trailer ($25 charge).
2. Inductance measured between secondary pins at 1 kHz, 0.1 Vrms, 0 Adc.
3. Volt-time product is for the secondary, between pin 2 and 4.
4. Primary current of 40 A causes less than 40°C temperature rise from
25°C ambient. Higher current causes a greater temperature rise (see
Temperature Rise vs Current curve).
Temperature Rise vs Current
5. Terminating resistance (RT) value is based on 1 Volt output with 40 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.
7 5.5 mm creepage and 5.0 mm clearance to meet reinforced insulation
for working voltage up to 136 V and basic insulation for working volt-
age up to 550 V with material group 3, pollution degree P2, OVCII, and
altitude up to 2 km.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
