SMT Planar Transformer – A0027-AL
Coilcraft’s surface mount planar transformers are ideal for
applications that require high efficiency in a low-profile
package. Planar transformers offer high power densities
along with great reliability and repeatability. The A0027-A
is designed to perform in push-pull topologies operating at
200 – 300 kHz. The auxiliary winding can be used to control
input current to PWMs.
To complete your design, Coilcraft offers a wide variety of
power inductors for use as input and output chokes.
