SMD Power Inductor HM66M Series Features: -40C to 125C operation temperature 10 amps maximum rated current 680 Henry maximum inductance value Temperature rise, maximum 40C Operating frequency up to 4MHz Magnetically shielded Low profile from Hmax: 3.0mm to 4.1mm depend on the case size Description: The HM66M is a shielded miniature low profile SMD inductors, with ferrite material core. It is characterized by low losses at high frequencies. The HM66M is designed specifically for power supplies and frequency converters that operate with fast switching power semiconductors on a GaN basis. The new power inductance is optimized for a frequency range from 700 kHz to 4 MHz. The HM66M is designed for use in systems with switching frequencies up to 4MHz and operating temperatures up to 125C. The part can be semi-custom designed to meet up to 155C in applications where needed. This series has a wide range of inductances and package sizes. The part is low profile (Hmax: 3.0 to 4.1mm). It is shielded and oeff rs high saturation current with low DC resistance. The HM66M is ideal for high power density applications where the ambient temperature exceeds 85C. Such applications include high efficiency DC -DC converters using high switching frequencies to 3 MHz as well as EMI and low pass DC filters used in the industrial, medical and telecommunication markets. Applications: Low profile buck DC -DC converters Low profile POL converters Output power filter for forward converters Power inductance for electronic breakers Industrial automation systems Industrial DC-DC converters Industrial EMI filters TT Electronics BI Technologies General Note A-1445, Jalan Tanjung Api, 25050 Kuantan, Pahang Darul Makmur, Malaysia TT Electronics reserves the right to make changes in product specificaoti n without Ph: +60 9 565 8888 nocti e or liability.
