EPCOS Series B82806D Pulse Transformers
EPCOS B82806D pulse transformers are designed for 60 W PoE++ applications, as well as for use in active clamp forward converters and switch-mode power supplies. The transformers are based on an EPCOS EFD 20 ferrite core, offering very low DC resistance values and a typical switching frequency of 200 kHz. Variants of the B82806D are available with various turn ratios to provide outputs from 3.3 V to 24 V. In PoE++ applications, this allows the B82806D to supply all types of devices with higher power demands, including video, point of sale, lighting, fire alarm, and building access systems. The small, surface-mount transformers are 100% high voltage tested to ensure reliability, are UL 1446 approved, and are rated for operation from -40°C to +125°C.
