Würth Elektronik WE-MTCI SMD Multi-Turn Ratio Coupled Inductors
Würth Elektronik WE-MTCI SMD Multi-Turn Ratio Coupled Inductors feature turn ratios of 1:1:5, 1:2, and 1:3. These inductors offer different inductance values in a small package of 5.2mm x 5.2mm x 3.1mm. This series provides functional isolation and assures stable performance through a temperature range of -40°C to +125°C. The inductors feature a coupling coefficient of up to 0.985, which means low leakage inductance. The higher coupling coefficient makes it an ideal solution for high-density isolated flyback converter applications. The isolation voltage of 0.8kV and different turn ratios between the two windings make these inductors a perfect solution for buck-boost converters with a second unregulated output voltage. The WE-MTCI inductors have 10μH to 33μH and are available in a 5030 package size.Features
