Premier Magnetics, introduces its expanded line of low-cost, high-performance transformers designed to support the full range of Power-over-Ethernet (PoE) applications from IEEE 802.3af (15.4W, max), IEEE 802.3at (30W), Cisco UPoE and other higher-power PoE extensions up to 60W. The low-profile, surface-mount devices operate over a wide frequency range, provide high isolation (1500V) and are available in […]
Offline transformers for LLC resonant half-bridge topology
Wurth Electronics Midcom is proud to announce the release of MID-LLCEPC; a new series of offline transformers using LLC Resonant Half-Bridge topology. With the low switching losses of the LLC topology, the MID-LLCEPC series yields very good efficiency, which makes the topology attractive with higher power levels. “Our package used for this series was designed […]
Reverse polarity protection: how can you provide it?
The reverse connection of a circuit to its DC power source, whether it’s a battery or power supply, can damage and even destroy the electronics. For this reason, many connectors are “keyed” to ensure correct connection. But there are many connections which are directly hard-wired using wires inserted into screw terminals, or ring or spade […]
Low-profile gate drive transformers feature 1.5 kV isolation
The new MID-GDT transformer series is now available from Wurth Electronics Midcom. These low profile gate drive transformers are surface mount with a maximum height of 5.38mm, and operate with a voltage-time product of at least 70 Vµs on secondary windings. These pick-and-placeable transformers feature 1500V isolation, and have an operating temperature of -40° to […]
