PMW range

PMW range

The PMW range are in the form of a welded heavy gauge mild steel can that is hermetically sealed. External connections are via ceramic bushings. The range may be supplied with fixing brackets, handles or lugs for lifting.

Specifications

They are impregnated and filled with a mineral oil. The container is manufactured from heavy gauge, cold rolled steel that is welded and hermetically sealed. The internal construction is designed to prevent movement when subjected to vibration or mechanical shock. The capacitors’ containers are primed and glossed. The capacitors may be supplied with fixing brackets, handles or lugs for lifting. Larger capacitors are mounted on wheels.

NOTE: The impregnant used is a non toxic highly refined, purified and inhibited mineral oil.

• APPLICATIONS: The PMW range of capacitors are specially designed for DC filtering and bypass applications such as high voltage power supplies for lasers, radar and x-ray, RF transmitters, traction equipment and generators where reliability and long life are prime considerations.
• 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 100ºC temperature change.
• Voltage Range: 1KVDC - 80kVDC
