The TLC range of capacitors are similar in design to the TPM range but are housed in a more robust container. They are manufactured using a mixed dielectric material that consists of polyester/polypropylene film and capacitor tissue. They are impregnated and filled with a mineral oil. The container is a Synthetic Resin Bonded Paper (SRBP) tube sealed at both ends with resin assuring a hermetic seal. The capacitors may be used in air, oil or SF6. They are terminated with M6 studs x 15mm long or tinned copper wire.

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

Applications: The TLC 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

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 20ºC.

 

Fig 3

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

 

Fig 4

Life expectancy: TLC type capacitors are designed for continuous operation at 65ºC rated voltage for 50000 hours . To achieve the same life expectancy at 85ºC derate 60% of rated voltage (fig 4).

Weight: The approximate weight in grams of capacitors in the TLC range can be estimated by multiplying the volume of the capacitor container by 1.2 x 10-3
