Planar Transformers Settle Into PoE, ‒48-V Network Power Apps
Two new series of surface-mount planar transformers from Coilcraft—the PL160 and PL300 series—bring high efficiency, DCR down to 7.2 mΩ, and leakage inductance as low as 0.20 µH to power over Ethernet (PoE) and ‒48-V network power applications.
