The TPM range of capacitors are manufactured using a mixed dielectic material that consists of polyester/polyropylene film and capacitor tissue. 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.

Applications: The TPM range is specifically designed for high voltage power supplies, general purpose bypass, coupling, filter applications, electrostatic air cleaners, X-ray power supplies and traction.

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.

 

Fig 1.

Ripple: 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.

 

Fig 2.

Power Factor: Variable; function of temperature and frequency see fig 2. 

Nominal value <0.5% at 20°C.

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: 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 (fig 4).

Weight: The approximate weight in grams may be calculated by multiplying the volume of the capacitor container by 1.2 x10-3
