Planar Choke Performs Like Wirewounds In Less Space

Vishay Intertechnology’s IPLA 32 high current planar choke inductor offers the same performance as wirewound devices in a fraction of the space. The component measures a paltry 31 mm x 43 mm x 22.2 mm and is rated for currents up to 110A.


With a recommended frequency range of 100 kHz to 800 kHz, the IPLA 32 forecasts more compact and lightweight dc/dc circuitry in electric and hybrid cars, off-road vehicles including forklifts, and all manner of embedded systems. The IPLA 32 is available in standard inductance values of 1 μH, 2 μH, 3 μH, and 4 μH. Magnetically shielded for low EMI, the inductor features a high self-resonance frequency and stable performance versus temperature.
