Buying advice

When selecting a power transformer, consider factors such as voltage rating, current capacity, mounting style (chassis, PCB, or toroidal), and efficiency. Toroidal transformers offer low noise and compact size but are more expensive. For high power applications, choose a transformer with adequate VA rating and good regulation. Always verify that the product is listed under 'Industrial & Scientific > Electronic Components' to ensure it meets your needs.
