New Transformer Supports IEEE 802.3 af-Compliant, Integrated PoE Powered Device and Pulse Width Modulation Controller Applications

RIVERSIDE, Calif., November 21, 2019 - Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced an addition to the company's flyback power transformer line. Designed to support IEEE 802.3 af-compliant, integrated Power-over-Ethernet (PoE) Powered Device (PD) and Pulse Width Modulation (PWM) controller applications, Bourns® Model SM13117EL provides DC/DC power conversion in isolated mode.

The SM13117EL flyback transformer features 13 watts of output power, 36 - 72 VDC/ 250 kHz input, 12 VDC/1.08 amp output and 1.5k Vrms withstanding voltage. This low profile, small form factor PoE flyback transformer also offers an extended -40 to +125 °C operating temperature range, low leakage inductance and excellent EMI performance. Ensuring safe operation, the electrical insulation of the transformer complies with the UL 1446 Class B (130 °C) Insulation System. The transformer bobbin carries the UL 94 V-0 flammability rating.

The features of Bourns' latest flyback power transformer make it an excellent power conversion solution for a broad range of PoE-powered devices including VoIP phones, WLAN access points and network cameras as well as with integrated PoE PD interface and PWM controllers offered by several leading IC manufacturers.

Bourns® Model SM13117EL flyback power transformer is available now and is RoHS compliant*. For more detailed information, please refer to the datasheet: www.bourns.com/docs/product-datasheets/sm13117el.pdf
