Ampohm FP-CA-AU: Metallized Polypropylene

Crossovers and signal path.

630 Volts

1.0uF to 40uF

AMPOHM FP-CA-AU capacitors are specially designed for high performance audio systems. The capacitors are hand wound and have their insulated copper leads hand soldered before being assembled in a plastic case and resin sealed.  The resin filled end identifies the outer winding. This construction results in the capacitors having low ESR and low inductance and possessing high stability with respect to both temperature and frequency. They are ideal for use in loudspeaker crossover networks and valve amplifiers where pure sound is at a premium. Features: Tension controlled precision hand-winding High quality metalized film  Hand-soldered internal connections Insulated copper leadout Low ESR Low inductance High stability with respect to both temperature and frequency Rigid and resilient plastic housing Custom values available Custom configurations - axial or radial Custom and terminations - including silver leadout Custom labelling and branding available

Ampohm FE-XAL: Metallized Polyester (Mylar)

Crossovers and signal path.

630 Volts

0.1uF to 6.8uF

Ampohm PF-XTI-AL: Paper in Oil - Tin Foil

Tone circuits and vintage sound.

630 Volts

0.001uF to 2.0uF

Ideal for high-end tone circuits including guitar tone circuits, Ampohm's tin-foil in oil capacitors combine vintage tonal colouring with modern manufacturing methods. Features: Hermetically-sealed enclosure for complete reliability and component confidence Tension controlled precision hand-winding Highest purity (99.99%) tin foil Hand-soldered internal connections Insulated copper leadout Custom values available Custom configurations - axial or radial Custom and terminations - including silver leadout Custom labelling and branding available

Ampohm PF-XAL-AL: Paper in Oil - Aluminium Foil

Tone circuits and vintage sound

630 Volts

0.01uF to 10.0uF

Ideal for tone circuits including guitar tone circuits, Ampohm's aluminium-foil in oil capacitors combine vintage tonal colouring with modern manufacturing methods. Features: Hermetically-sealed enclosure for complete reliability and component confidence Tension controlled precision hand-winding Highest purity aluminium foil Hand-soldered internal connections Insulated copper leadout Custom values available Custom configurations - axial or radial Custom and terminations - including silver leadout Custom labelling and branding available

300 Volts

1.0uF to 10.0uF

Where there is a requirement for rated voltage less than 630V, the PF-XAL-AL series are also available in a 300V series, giving the dual advantages of lower price and reduced physical size.

Ampohm PF-XAL-W-AL: Paper in Wax

Tone circuits and vintage sound

630 Volts

0.01uF to 10.0uF

Ideal for high-end tone circuits and for vintage tone signal path applications, Ampohm's paper-in-wax capacitors give the benefits of classic tonal colouring of paper-in-wax capacitors without the normal drawbacks. These are the only standard manufacture paper-in-wax in an hermetic package available. Features: Hermetically-sealed enclosure for complete reliability and component confidence Tension controlled precision hand-winding Hand-soldered internal connections Insulated copper leadout Custom values available Custom configurations - axial or radial Custom and terminations - including silver leadout Custom labelling and branding available
