EE25 Small power transformer 

A small power transformer is a type of transformer that is designed to handle low voltage and low power applications. These transformers are typically used in electronic devices, such as audio equipment, power supplies, and small appliances. Small power transformers are typically rated between 1 VA and 50 VA, with voltage ratings between 6 V and 24 V. They are typically constructed with a laminated iron core and copper wire windings. The primary winding is connected to the power source, while the secondary winding is connected to the load. Small power transformers are used to step up or step down voltage, isolate circuits, and reduce noise.
