SMTPlanarTransformer – A9845-AL
Coilcraft’s surface mount planar transformers are ideal for applications that require high efficiency in a low-profile package. They are designed to perform in push-pull topologies operating at 200 – 300 kHz. The auxiliary winding can be used to control input current to PWMs.
Planar transformers offer high power densities along with great reliability and repeatability.
The A9845-A has a smaller footprint and lower profile than our other planar transformers. The circular windings provide very low DCR and excellent leakage inductance values.
To complete your design, Coilcraft offers a wide variety of power inductors for use as input and output chokes. To request free evaluation samples, contact Coilcraft or visit www.coilcraft.com.
