To order a custom wind transformer, select the primary inductance and the secondary inductance from the drop down menus.  You will recieve an email to confirm the resulting ratio before your project begins.  Transformer ratio is equal to the square root of the inductance ratio.
 
Actual inductance will vary up to 20% due to core magnetic variation, and lead time for custom winds is up to two weeks.  Transformers are easily mounted with an included M3 bolt and threaded insert.  Due to the custom nature of these parts, we also cannot offer returns unless there is a fault in the delivered part.  For questions please reach out through the contact page.
