Murata Manufacturing Co., Ltd. expands lineup of isolated DC-DC converters for PoE IEEE802.3af

  • Power Products

9/5/2025

Murata Manufacturing Co., Ltd. has expanded its lineup of isolated DC-DC converters for PoE*1 with the launch of an IEEE802.3af-compliant isolated DC-DC converter for PD*2 (hereinafter, ‘the product’). Murata has already started mass production of the product, and samples are available upon request.

  • *1PoE: Power over Ethernet. A technology that enables power supply over LAN cables used to build networks.
  • *2PD: Powered Device. A device that receives power in a PoE system.

PoE technology enables power supply over LAN cables used to build networks, improving installation flexibility, and reducing costs. In recent years, network-enabled devices such as security cameras and biometric authentication equipment have increasingly adopted PoE technology. Against this backdrop, demand for compact power modules for PoE-compatible devices is growing. In particular, biometric authentication devices typically require around 10 W of power, making the IEEE802.3af standard, which supports up to 15 W, an ideal match.

Accordingly, Murata has developed this product compliant with IEEE802.3af. The product’s compact, low-profile design (1.02×0.58×0.27 inches (26×14.8×6.8mm)) enhances layout flexibility on circuit boards. It is mainly suited for camera modules and biometric authentication devices that require space-saving and low-noise characteristics, and contributes to the miniaturization of other communication devices.

Key features

  • Isolated DC-DC converter module compliant with IEEE802.3af Class specifications
  • Compact and low-profile (1.02×0.58×0.27 inches (26×14.8×6.8mm)) for high layout flexibility
  • Wide operating temperature range (-40°C to +85°C) for versatile applications

Applications

  • IEEE802.3af-compliant devices including wireless access points, biometric authentication devices, security cameras, camera modules, IP phones, and audio speakers
