A range of paper and polyester dielectric, oil-filled capacitors, designed for use in audio equipment such as pre-amplifiers, amplifiers and loudspeaker crossover networks are now available.

The C50309 are designed for high performance and long life and are said to feature one of the finest grades of capacitor kraft paper and polyester.

Components in the range are rated for operation at 600V DC and standard capacitance tolerance is said to be   +/-10 percent.  Insulation resistance is quoted at 6000 megohm-microfarads minimum, while the dissipation factor is less than 1percent measured at 120Hz. 

The operating temperature covers the full military range from -55 to 125oC at full rated voltage.

The company advises, a typical capacitor in this range is the C50309-6224K, which offers a capacitance of 0.22µF +/-10%.  The hermetically-sealed tubular brass case diameter is 17mm, and overall length is 47.6mm.  The 20awg leads are solder-coated oxygen free solid copper.

These capacitors are ideal for high end crossover circuits and filter applications in amplifiers, pre-amplifiers and power supplies, plus other specialist, high quality audio equipment.
