Exxelia’s CCM magnetic components dedicated to harsh environment applications

18 January 2023

Exxelia developed the Chameleon Concept Magnetics (CCM) family of products to withstand the harsh environments of aerospace and particularly of space applications. CCM technology is Exxelia’s response to the growing interest of electronic engineers for inductors and transformers with multiple outputs, high power density and reduced footprints. These ‘chameleon-like’ products can be either an inductor or a transformer depending on the inductor ranges and complement the existing SESI and TT product families. New Yorker Electronics has been on the forefront with the certified distribution of this technology since its inception.

The CCM product family currently consists of five sizes, CCM4/5/6 and CCM20/25, allowing optimized component design in a pick-and-place surface mount (SMD) package. Through-hole (TH) packages are also available upon request. The maximum transferable power in the CCM25 is about 200 W, depending on the operating conditions of the transformer. The CCM30 is currently under development and this model would approach 350 W. The CCM series is particularly flexible with a number of pin options available, from 2×6Source: New Yorker ElectronicsSource: New Yorker Electronics pins for the smallest package, up to 2×10. Qualified for aeronautics and space applications, the CCM product line features abundant robustness. The monolithic design provides high mechanical performance, proven by successfully testing in accordance with MIL-STD-202 (methods 213 and 204).

CCM transformers and inductors can operate over a wide temperature range with a minimal operating temperature of -55° C. The standard thermal grade of the technology is 140° C. Thanks to the technology design, the thermal resistance is 30% lower than standard industrial components. The epoxy molding that protects the winding ensures a lower temperature gradient and a better heat dissipation. Each unit is thoroughly tested with a dielectric withstanding strength of 1,500 V AC. Component materials meet UL 94-V0 rating.

Exxelia can evaluate losses and related temperature rise thanks to an in-depth knowledge of CCM technology. Thermal resistance data is available for each package size. Exxelia can also manufacture products in CCM technology according to MIL-STD-981.
