Micrometals introduces new EQ distributed gap cores for high frequency switch-mode power applications
Micrometals, a leader in high performance core solutions for power applications, is proud to introduce its new series of EQ distributed gap cores. The rectangular geometry of the EQ body is ideal for surface mount applications while the round center post readily accepts helical ﬂat wire coils, or bobbins with round wire. The cores are offered in six industry standard geometries from 20mm to 50mm, three exclusive material formulations, and three reference permeability values.
The new EQ geometries are available in Micrometals exclusive material formulations of Sendust (MS), Hi-Flux™ (HF) and FluxSan™ (FS - Iron Silicon) with 26, 40 or 60 permeability values. These uniquely formulated materials offer a combination of high saturation magnetization and low losses, making them well suited for switching applications up to 1MHz. The distributed gap nature of these materials means that they can be used with little or no center-leg gap, greatly reducing the losses associated with fringing ﬂux at higher frequency. EQ cores offer several key advantages over toroid or E core geometries including better self- shielding and high winding density. Jim Cox, Micrometals President commented “Micrometals has a long history of providing the most trusted and reliable powder formulations, and consistently delivering uncompromising performance in every core we deliver. These new EQ shapes will allow our customers to achieve new levels of performance and efficiency in a very compact package.”
The EQ series offering has been incorporated into the Micrometals Online Inductor Design Tool, for facilitating material selection and design optimization - https://www.micrometalsapc.com/design-software
