Resistors

In our BS- and CECC-approved UK based production facility, Charcroft Electronics manufactures our own Audio resistors, The CAR (Charcroft Audio resistor) & SCAR (Charcroft Audio resistor surface-mount). These are composed of Vishay’s Bulk Metal® Z-foil technology, which offers improved sound quality and provides a combination of low noise and low inductance/capacitance, making it unrivalled for applications requiring low noise and distortion-free properties.

CAR resistors are now offered with 100% Component Linearity Testing (CLT) to detect potential defects beyond the limits of standard visual and electrical inspection. These small defects can distort the harmonic performance of the component and only Charcroft is able to offer this testing as standard – providing the reassurance of achieving the cleanest sound possible.

Charcroft offers a wide range of resistors for all applications. If you cannot find what you are looking for below, please contact us with your enquiry.

The CAR, composed of Vishay’s Bulk Metal® Z-foil technology, with improved sound quality, provides a combination of low noise and low inductance/capacitance, making it unrivalled for applications requiring low noise and distortion-free properties. While the regular foil resistors are already widely acknowledged as the leading resistors for audio applications, the special “naked Z-foil resistor” design without case or encapsulation, adds an additional dimension for reducing signal distortion and increasing clarity in signal processing.

The SCAR also uses Vishay’s Bulk Metal® Z-foil technology and offers all the features of the leaded CAR but in a surface mount version with wrap around terminations.

CAR resistors are now offered with 100% Component Linearity Testing (CLT) to detect potential defects beyond the limits of standard visual and electrical inspection. These small defects can distort the harmonic performance of the component and only Charcroft is able to offer this testing as standard – providing the reassurance of achieving the cleanest sound possible.
