Bourns has launched a flyback transformer for IEEE 802.3 af-compliant, integrated Power-over-Ethernet (PoE) Powered Device (PD) and Pulse Width Modulation (PWM) controller applications,
The SM13117EL flyback transformer features 13W 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 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 Insulation System to 130 °C. The transformer bobbin carries the UL 94 V-0 flammability rating.
The transformer is aimed at power conversion in 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 chip makers.
The Bourns Model SM13117EL flyback power transformer is available now and is RoHS compliant
