          TLC Range

          Back

          TLC Range

          The TLC range of capacitors are similar in design to the TPM range but are housed in a more robust container with M6 x 15 axial stud terminals as standard.

          Specifications

          They utilise a mixed dielectric material that consists of polyester or polypropylene film and capacitor paper and 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. (M10 x 20mm studs can also be supplied on request).

          Note: The impregnant used is a non-toxic highly purified and 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

          RIPPLE:

          RIPPLE.png

          Ripple: The sum of the peak ripple voltage and the DC voltage should not exceed the rated voltage. The graph above shows 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: TLC 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.

          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
