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: 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 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
