PMR range

PMR range

The PMR range are in the form of a rolled-seam tinplate can that is hermetically sealed. External connections are via ceramic bushings with threaded studs or solder tags.

Specifications

The PMR range are impregnated and filled with a mineral oil. The container is a rolled-seamed tin plate case that is hermetically sealed. The internal construction is designed to prevent movement when the capacitor is subjected to mechanical shock or vibration. External connections are via ceramic terminals with threaded studs or solder tags. Capacitor are supplied with clip-on brackets. Other brackets are available on request. These capacitors can be mounted in any postion. The finish is a coat of high build light grey weatherwork cellulose enamel paint (other colours available on request). 

Note the impregnant used is a non toxic highly refined, purified and inhibited mineral oil.

APPLICATIONS

The PMR Range of capacitors is specifically designed for DC apllications such as filters, bypass and coupling of low frequency audio. Other apllications include:

• Pulse forming networks
• Oscillator Circuits
• Energy Storage
• Arc and Spark Suppression
• Integrating Circuits
• High Voltage Smoothing

Other Information

• Capacitors required for A.C. applications and High Discharge rates can also be designed from the PMR range. Consult Hivolt Capacitors Limited for your specific requirements.
• Capacitance Range: 0.01µF – 100µF. The tolerance is +/-10%. Other tolerances are available on request. Nominal values measured at 1kHz.
• Temperature Range: -55°C to 85°C. The nominal voltage rating is applicable from -55°C to 85°C. Derating is required for higher operating temperatures.
• Temperature Coefficient: Capacitance will increase by 2% per 100°C temperature change.
• Voltage Range: 200Vdc – 40kVdc
