Vishay Introduces Industrial and Automotive IHLE Integrated Electric Field Shielded Inductors to Reduce Costs and Save Space

Recently, Vishay Intertechnology, Inc. announced the launch of new industrial and automotive-grade 5050 form factor devices --- IHLE-5050FH-51 and IHLE-5050FH-5A, expanding the IHLEa series of ultra-thin, high-current inductors with integrated electric fields Shielding reduces EMI. Vishay Dale IHLE-5050FH-51 and IHLE-5050FH-5A do not need to add extra electric field shielding measures, thus reducing costs and saving board space.

The recently released inductor uses a copper-tin plated integrated shield to suppress the electric and magnetic fields generated by EMI. When the integrated shield is grounded, the electric field at 1 cm (above the center of the inductor) can be reduced by -20 dB. The inductor can work at a high temperature of +155 ° C, and the coplanarity of the 4 pins is less than 100 μm. It is suitable for energy storage of DC / DC converters, and the frequency can reach 2 MHz. At the same time, the inductor self-resonant frequency (SRF) range Excellent noise attenuation performance in high current filtering applications.

IHLE-5050FH-51 applications include desktop PCs, servers, high-current point-of-load (POL) converters, small high-current power supplies, and battery-powered equipment. IHLE-5050FH-5A is AEC-Q200 qualified for use in automotive engine and transmission control units, diesel injectors, motor noise suppression, wipers, electric mirrors and seats, entertainment / navigation systems, heaters, and LED and HID lighting .

The inductor package uses a 100% lead-free (Pb) shielded composite structure, which reduces noise to a very low level. It has extremely high resistance to thermal shock, humidity, and mechanical vibration, and can handle high transient current spikes without saturation. IHLE-5050FH-51 and IHLE-5050FH-5A comply with RoHS and Vishay green standards and are halogen-free.
