          TPM Range

          The TPM range are in the form of a Synthetic Resin Bonded Paper tube hermetically sealed at both ends with resin . Axial terminations are via M5 x 12mm studs or tinned copper wire.

          Specifications

          They are impregnated and filled with a mineral oil. The container is a Synthetic Resin Bonded Paper tube sealed at both ends with resin assuring hermetic sealing. The capacitors are terminated with M5 x 12mm studs or tinned copper wire.

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

          Capacitance Range: 0.0005μF – 2μF. The tolerance is +/-10%. Other tolerances are available on request. Nominal values measured at 1kHz.

          Temperature Range: -55oC to 85oC. The nominal voltage rating is applicable from -55oC to 85oC.

          Temperature Coefficient: Capacitance will increase by 2% per 100oC temperature rise.

          Voltage Range: 1kV – 100kVDC.

          Note: The impregnant used is a non-toxic highly purified and inhibited mineral oil.

          APPLICATIONS:The TPM range of capacitors are specifically designed for high voltage filters and can be successfully used in the following applications. High Voltage Smoothing; Induction Heating; RF Transmitter Power Supplies; X-Ray Power Supplies.

          Capacitance Range: 0.001μF – 2μF. The tolerance is +/-10%. Other tolerances are available on request. Nominal values measured at 1kHz.

          Temperature Range: -40°C to 85°C. Derating is required for higher operating temperatures.

          Temperature Coefficient: Capacitance will increase by 2% per 100°C temperature rise.

          Voltage Range: 1kV – 100kVDC

          RIPPLE:

          RIPPLE.png

          The sum of the peak ripple voltage and the DC voltage should not exceed the rated voltage. Refer to graph fig 1 for permissible peak-to-peak ripple voltage as a percentage of rated voltage for various frequencies.

          Test Voltage: V Test
          For DC rating <20kV:V Test = 2.0 x Rated Voltage for 1 minute.
          For DC rating ≥20kV:V Test = 1.5 x Rated Voltage for 1 minute.
          Case to terminal Test voltage = V Test + 1kV

          Power Factor

          Power Factor: Variable; function of temperature and frequency. See fig 2. Nominal value < 0.5% at 20oC.

          Dieletric Resistance

          Dieletric Resistance: (Parallel resistance) Indicated by the graph of insulance (Mohms x μF) vs Temperature (fig 3). The insulance(Mohms x μF) is nominally 10000s at +20oC. (Measurements taken after 1 minute with an applied voltage of 500V).

          Life expectancy

          life 03.jpg

          Life expectancy: TPM type capacitors are designed for a life expectancy of 50000 hours at 65oC. To achieve the same life expectancy at 85oC derate to 60% of rated voltage.
