Details

EI laminated transformer is a traditional transformer, construction is simply. The EI laminated,bobbin, bracket and other

components are already produced as mass production. So that the production is simple and standard, and the costing is lower. It is widely used in various electronic and industrial equipment.

Main advantages:

Low costing

Easy assembly

The power can make less than 5VA, and the costing is much lower than toroidal

Can proteced with resettable thermal fuse or non-resettable thermal fuse

Applications:

Audio & Vedio Amplifier

AC to AC Power Supply

Electronic Equipment

Lighting

Sample Lead Time： 4~7 days

Production Lead Time：7~35 days (Special case can negotiate)

Quantity：No MOQ Require
