Charcroft announces ultra-high-precision resistor

Charcroft has announced the immediate availability of a naked ultra-high-precision resistor for high-end audio, multimedia and broadcast applications.

Based on Vishay's Bulk Metal Z Foil resistor technology, the Charcroft CAR resistor is supplied with a protective coating, rather than moulding or encapsulation, to deliver virtually distortion-free signal processing for the highest level of perceived sound clarity.

Paul Newman, Charcroft's managing director, said: 'These resistors build on the performance achieved by the previous generation of foil resistors to establish a new benchmark for clarity and purity.

'They are designed to improve signal processing integrity when replacing conventional resistors in differential amplifiers or power supplies for high-end audio products.

'CAR resistors can also be used in the feedback, loading and gain stages of audio circuits.' In addition to a low current noise of less than -40dB, CAR resistors achieve an excellent temperature coefficient of resistance (TCR) and power coefficient of resistance (PCR), while offering a fast rise time of 1.0ns without ringing.

They also feature a non-inductive non-hot-spot design and withstand electrostatic discharges of over 25kV.

CAR resistors can be trimmed to any tolerance and any value within the resistance range of 10ohm to 100kohm and are available now, with a typical lead-time of 72 hours for samples, and three weeks for standard orders.
