WE-TDC SMD Shielded Coupled Inductors

Würth Elektronik WE-TDC series is a coupled inductor series designed for DC/DC converters with SEPIC, CUK, ZETA, and non-isolated flyback topologies. The series is available in an 8 x 8 mm package size in a standard 4 mm height as well as a low profile version of 2 mm height. The key advantages of the series besides the small size are the low leakage inductance, low losses, and high current capabilities. With an operating temperature of -40°C to +125°C and its magnetically shielded housing, the WE-TDC is the perfect coupled inductor solution for industrial, metering, and medical devices as well as battery powered mobile devices.
