Würth Elektronik WE-PSPA Push Pull & Gate Drive Transformer

Featuring wide operating temperatures and output voltage for a variety of environments

The Würth Elektronik WE-PSPA is a small sized power transformer specially designed for Push-Pull and Gate Drive applications.

It is important to note the product of time and voltage until the core reaches saturation. This is one of the parameters of the Push-Pull and Gate Drive Transformer. A voltage-time product (volt-second) is calculated from the inductance (L) and the saturation current (Isat). To ensure sufficient volt-seconds are available, the frequency and pulse bandwidth of your application should be checked before selecting a transformer. Because of its automated manufacturing process, the WE-PSPA transformers by Würth Elektronik are fully reliable for automotive applications.

An important parameter of the Push Pull and Gate Drive Transformer is the product of time and voltage, until the core saturates. The voltage-time product V- t (unit: volt-second) is calculated of the inductance L and the saturation current Isat. When selecting a transformer, you should ensure, that enough volt-seconds are available, depending on the frequency and pulse bandwidth of the application.
