Pulse Electronics Corp. has announced line of 5kVrms isolation power transformers aimed at communications interfaces such as RS485, CAN, MODBus and ProfiBus for automation, automotive and smart grid applications. The PH9385 transformer series attains 12mm creepage in a patent-pending, low-profile, compact, 17mm x 16mm x 7mm surface mount package, detailed the company.

Pulse's transformer is 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 series builds on its PH9085 series of 2.5kV power transformers to offer protection for higher isolation applications. These transformers are RoHS-compliant and meet standard EIA481 requirements. They are available in tube and tape-and-reel packaging. Prices start at about $0.84 (FCA HK) for 10,000 pieces. Lead time is eight weeks. Samples are available.
