New surface mount inductors meet complex requirements of high power density applications

28-08-2019 | TT Electronics | Passives

TT Electronics has announced two new SMD power inductors: the HM66M series for use in high-frequency power conversion systems and EMI filter applications, and the HM78M series for use in high density and high-frequency DC-DC converter applications.


The HM66M series power inductors are intended for the complex industrial and telecommunications markets. The device is a shielded, miniature low-profile SMD inductor that combines a ferrite material core for important permeability and temperature advantages. Distinguished by low losses at high frequencies, these inductors are ideal for power supplies and frequency converters that work with fast-switching power semiconductors on a GaN basis. Power inductance is optimised within a frequency range from 700kHz to 4MHz and created for systems that need switching frequencies up to 4MHz and operating temperatures at 125C. The series is provided in three standard case sizes: 60, 70 and 84.


The HM78M series power inductors are shielded, ferrite-based SMD inductors intended for usage in high-frequency DC-DC converter configuration popular in industrial markets. With high inductance and current values, these power inductors provide a switching frequency configuration range of 100kHz to 3MHz, making them fit as a buck converter or an EMI filter. This series comes in two standard package sizes: 10 and 20.


Semi-custom designs of both devices are also available to satisfy special requests.


“TT’s new SMD inductors offer greater operating temperature ranges in a smaller package than competitive options,” said Raj Singaraju, global product line director, TT Electronics. “Designers now have a clear advantage in addressing the complex needs of high power density applications common in today’s industrial and telecom equipment markets.”
