High-Isolation Power Transformers, PH9385-Series

Pulse Electronics, a YAGEO Company introduces their PH9385-series of 4 kV_RMS isolation power transformers, which achieve 12 mm creepage in a patent-pending, low-profile, compact, 17 mm x 16 mm x 7 mm surface-mount package.

The PH9385 series of switch-mode power-supply transformers are built with a unique Sidecar package that has the coil inserted at one side of the open package and the high-isolation pins placed on the other side. This configuration separates the coil and pins so there is a greater creepage distance between them. It also enables the package to be smaller while still maintaining an optimal creepage distance. The PH9385 are available in tube and tape-and-reel packaging.

The PH9385-series builds on its PH9085-series of 2.5 kV power transformers to offer protection for higher-isolation applications. These transformers are RoHS-compliant and meet standard EIA481 requirements.
