Power Inductors
HM78M series
Features:
• Operating Temperature Range –40°C to +125°C • Ambient Temperature, Max +85°C • Temperature Rise, 40°C • Operating Frequency up to 3MHz
Description:
The HM78M series of power inductors is ferrite based, magnetically shielded, and features low resistance values. It is shielded but has a low DC resistance and high saturation current, able to meet 125°C, with a maximum temperature rise of 40°C. This series has wide range of inductances from 1μHenry to 680μHenry and is comprised of two package sizes which is 10 and 20. The HM78M is ideal for high power density applications where size is critical and ambient temperature is less or equal to 85°C. It is designed for high switching frequencies up to 3MHz as well as for EMI and low pass filters.
Applications:
• Buck DC-DC converters • High efficiency DC-DC converters used with battery supply • EMI inductance in PI 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 specification without Ph: +60 9 565 8888 notice or liability.
