Magnetic components dedicated to harsh environment applications

19-01-2023 | New Yorker Electronics | Power

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

The product family currently comprises five sizes, CCM4/5/6 and CCM20/25, enabling optimised component design in a pick-and-place SMD package. TH packages are also available upon request. The maximum transferable power in the CCM25 is approximately 200W, depending on the operating conditions of the transformer. The CCM30 is currently under development and this model would approach 350W. The series is especially flexible with several pin options available, from 2×6 pins for the smallest package, up to 2×10. The product line is qualified for aeronautics and space applications and offers abundant robustness. The monolithic design supplies high mechanical performance, proven by successful testing in accordance with MIL-STD-202 (methods 213 and 204).

These transformers and inductors can function over a wide temperature range with a minimal operating temperature of -55C. The standard thermal grade of the technology is 140C. The thermal resistance is 30% lower than standard industrial components, thanks to the technology design. The epoxy moulding that protects the winding provides a lower temperature gradient and a greater heat dissipation. Each unit is thoroughly tested with a dielectric withstanding strength of 1,500VAC. Component materials meet UL 94-V0 rating.

Typical application fields include aeronautics and space, common mode chokes, PFC chokes, gate drive transformers, SMD filtering chokes, current transformers, flyback transformers, forward transformers, and push-pull transformers.
