Part Number: BSC25-Z305A
Function: Flyback Transformer for TV
Manufacturer: Goldstar, ETC
BSC25-Z305A is Flyback transformer for TV. A flyback transformer, also known as a line output transformer (LOPT), is a type of transformer used in electronic circuits to generate high-voltage outputs. It is commonly used in cathode-ray tube (CRT) displays, old-style televisions, computer monitors, and some power supply applications.
The primary function of a flyback transformer is to store energy in its primary winding when a current flows through it. When the primary current is interrupted, typically by a transistor switching off, the stored energy is released into the secondary winding. This abrupt energy release induces a high voltage across the secondary winding, generating a high-voltage pulse or spike.
In CRT displays and TVs, the high-voltage output generated by the flyback transformer is used to accelerate electrons towards the screen, creating the visual image on the phosphor-coated glass.
