ESQ – Super Q Coil.

The SUPER Q coil characteristics virtually match any air core coil given a frequency range of 0 Hz to 3000 Hz. Except, the SUPER Q has a much lower DC resistance and much higher quality factor than a comparatively priced air core coil. The SUPER Q coil features a specially ‘H’ shaped, micro thin silicon grain oriented steel. The special ‘H’ shape allows for minimal magnetic flux leaking and increases the coils effective permeability. The high permeable design allowed us to achieve extremely low DC resistance and significantly reduce distortion. The SUPER Q coil is also totally void of any magneto striction distortion. This is due to the plastic encapsulation (insert molded) of the low distortion steel. ERSE designed the plastic molded bobbin with two mounting areas to allow for ease of mounting.
