1. Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (150 parts per full reel). Quantities less than
full reel available: in tape (not machine ready) or
with leader and trailer ($25 charge).
2. Inductance is for the primary, measured at 200 kHz, 0.1 Vrms, 0
Adc.
3. Leakage inductance measured between pins 1 and 3 with all other
pins shorted.
4. Output is for each secondary. Output of the aux winding is 10 V,
50 mA.
5. Based on 280 mT at 25°C and number of turns on pins 1-3.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before
soldering.
Why is it called a flyback transformer?
The reason it is called a flyback transformer is because the primary winding uses a relatively low-voltage saw-tooth
wave. The wave gets strengthened first and then gets switched off
abruptly; this causes the beam to fly back from right to left on
the display.
