New RT chokes series from schaffner: More performance in the same compact size

Schaffner has launched the new RT series of common-mode chokes, which offer superior performance without increasing component size. The RT8121, RT8131, RT8521 and RT8531 models in this series use nanocrystalline core technology to achieve attenuation levels up to 15 dB higher than their ferrite-based predecessor. This improvement is achieved while maintaining the same compact 65 mm diameter, facilitating integration into space-constrained designs.

Nanocrystalline core technology:

Nanocrystalline core technology is the basis of the new RT series, enabling significantly improved attenuation performance compared to previous versions. This advancement in technology provides increased filtering power in the relevant frequency bands of the electromagnetic compatibility (EMC) spectrum, offering an effective solution for eliminating common mode electromagnetic noise.
