About this product
A small EI-core step-down transformer with a single 9V AC secondary rated at 300mA, intended for light linear power supplies and low-current AC applications. It is not a center-tapped 9-0-9 unit, so it cannot provide a dual-polarity supply directly.

Frequently asked questions
What is the price of 220V to 9VAC 300mA EI Step-Down Transformer (Single Secondary) in Egypt?
220V to 9VAC 300mA EI Step-Down Transformer (Single Secondary) currently costs 85 EGP in Egypt.
Where can I buy 220V to 9VAC 300mA EI Step-Down Transformer (Single Secondary) in Egypt?
220V to 9VAC 300mA EI Step-Down Transformer (Single Secondary) is available from Microohm. Compare the offers above to find the best price.
Can I use it as a 9-0-9 transformer?
No. It has a single secondary winding without a center tap, so it cannot be used as a 9-0-9 transformer.
Why is the DC output higher than 9V after rectification?
9V AC RMS corresponds to about 12.7V peak. A bridge rectifier removes two diode drops, and a filter capacitor brings the DC closer to the peak value, so the DC is higher than 9V.
