Fullerton, Calif. TT electronics' BI Technologies Magnetic Components Division has developed a series of DC/DC converter transformers specifically for Power-over-Ethernet (PoE) applications. Available in surface-mount packages, the HM110 series power transformers are available for a wide variety of output voltages.
The HM110 series transformers feature flyback topology and are available in power ratings from 5 W to 15 W for the three PoE power ratings. Applications include security cameras, wireless access points and other PoE applications.
The HM110 series PoE transformers are available in power ratings of 5 W, 6 W, 8 W, and 15 W, with inductance values from 180 uH to 70 uH. DC resistance ranges from 2.5 milliohms (mΩ) to 75.0 mΩ and isolation is rated at 1500 Vrms. The operating temperature range is -40°C to 125°C. The devices are RoHS compliant. Custom specifications are available.
The transformers are available in the following measurements:
- 5 W: 15.0 x 22.5 x 8.5 mm
- 6 W: 16.0 x 14.0 x 7.5 mm
- 8 W: 17.5 x 22.5 x 10 mm
- 15 W: 13.5 x 17.8 x 12.5 mm
Pricing: Typical pricing is approximately $0.65 to $1.05 depending on volume.
Availability: Delivery is from stock to 10 weeks. The transformers are available in 13-inch diameter embossed tape and reel packages.
