Arizona Capacitors Blue Cactus - Mylar/Paper/Oil/Aluminum Foil Capacitor, C50309
Arizona Capacitors, based in the US, manufacture highly regarded audio signal capacitors as part of a huge range of both Audio and Industrial capacitors. They have recently re-organised how their audio capacitors are distributed.
We have invested in 3 of their Cactus aluminium foil range of capacitors, all of them are similarly priced but vary in their composition slightly. Here we have the Blue Cactus, made up of a kraft paper and Mylar di-electric, with a higher proportion being Mylar, and aluminium foil electrode, impregnated with high purity mineral oils. The case is hermetically sealed into an insulated electro-tin plated brass tube with glass to metal compression end seals with soft solder to the ends to ensure a complete hermetic seal. The leadouts are tinned OFC copper. These capacitors offer outstanding performance and long life.
- Capacitance range: 0.1uF to 3.3uF (higher values to follow)
- Tolerance: +/- 10%
- Maximum voltage: 600Vdc
- Dissipation factor: Less than 1.0% when measured at 120 Hz using a GR 1658 or equivalent.
- Insulation resistance: The product of insulation resistance in megohms and the capacitance in microfarads shall be 6000 megohm-microfarads minimum. However, I.R. need not exceed 18000 megohms.
- Operation temperature range: -55 to 85°C at full rated voltage
HFC are no longer replenishing stock of this range, but we still hold a large quantity of units.
