Choke inductor delivers same performance as wirewounds in fraction of space

Vishay Intertechnology now offers a new high current planar choke inductor offering the same performance as wirewound devices in a fraction of the space. The new IPLA 32 measures only 31mm x 43mm x 22.2mm but is rated for currents up to 110A, providing high power density DC-DC converters to employ a significantly smaller footprint. With a suggested frequency range of 100kHz to 800kHz, the device enables more compact and lightweight DC-DC circuitry in electric and hybrid cars, off-road vehicles including forklifts, and all manner of embedded systems. The device is available with standard inductance values of 1µH, 2µH, 3µH, and 4µH. Magnetically-shielded for low EMI, the inductor has a high self-resonance frequency and very stable performance versus temperature. In addition to the standard versions, the device can be provided with various pin-out designs, current ratings and inductance values. The device has an operating temperature range of 55C to +125C and typical thermal resistance from 2W/C to 10.5W/C depending on the variety of heatsink used. 3D models are offered to assist the design-in process.
