PERFORMANCE CHARACTERISTICS
FIGURE 1 GENERAL SPECIFICATIONS FOR SHARMA MICA CAPACITORS The SHARMA Mica capacitors meet the required commercial specifications and theEIA requirements. The CMO series capacitors also meet the military specifications MIL-C-5. The actual specifications and dimensions of the capacitors are mentioned under each series in the catalog. CAPACITANCE The capacitance of mica capacitors is measured at 1 M Hz ±10% for capacitance values up to 1000 pF and at 1 K Hz ±10% for capacitance values above 1000 pF. The capacitance value when measured at 25 °C shall be with in the tolerance specified. DISSIPATION FACTOR The dissipation factor for mica capacitors are measured at 1MHz for values up to 1000 pF and at 1 KHz for values above 1000 pF. The values shall remain within the specified values. The variation pattern of dissipation factor for different values of capacitance are also shown in the Figure 3. INSULATION RESISTANCE The insulation resistance is measured at 50 ±5 V for capacitors with rated voltage of 50 V DC and at 100 ±10 V for capacitors with higher voltage rating. The insulation resistance thus measured at 25 °C shall meet the specified limits. The variation of insulation resistance for different capacitance values at 25 °C is shown in Figure 1. After certain tests listed below the insulation resistance value changes and these values are plotted in Figure 2. Figure 4 indicates the variation pattern of insulation resistance with capacitance value at different temperature conditions. WITHSTANDING VOLTAGE The mica capacitors are designed to withstand higher voltage than the rated voltage for limited time. These capacitors shall withstand 200% of the rated voltage for 1 to 5 seconds when applied with a limiting surge current value of 50 mA. VIBRATION GRADE The capacitors shall be subjected to a harmonic motion having an amplitude of 1.5 mm and the frequency which is varied between the limits of 10 and 55 Hz. The entire frequency range from 10 to 55 Hz and then back to 10 Hz shall be traversed in approximately 1 minute and the motion shall be applied for a period of 1hour in each of the three mutually perpendicular directions. After testing, when the electrical measurements are performed: 1. The insulation resistance shall be more than 30000 M Ohms for capacitance value up to 10000 pF. Please refer to Figure 2 for acceptable variation pattern for Insulation Resistance for values above 10000 pF. 2. The dissipation factor shall be within the original specified limits. Please also refer to Figure 3 for variation pattern of dissipation factor with respect to capacitance value. 3. The capacitance change shall not exceed ±1% or ±1 pF whichever is greater. SOLDERING HEAT RESISTANCE Both leads of the capacitors shall be immersed in molten solder at a temperature of 270 °C for 3 to 4 seconds. After the test the capacitors shall meet the initial requirements of the Withstanding voltage and the Capacitance change shall not exceed ± 0.55 or ± 1 pF. MOISTURE RESISTANCE Capacitors shall be subjected to a temperature of 40 ±2 °C at 90 to 95 % relative humidity for 240 ±8 Hours. After the test: 1. The samples shall meet the after test requirement of Insulation resistance values as furnished in Figure 2. 2. The dissipation factor shall be within 1.5 times the original specified limits. Please also refer to Figure 3 for variation pattern of dissipation factor with respect to capacitance value for original limits. 3. The capacitance change shall not exceed ±3% or ±1 pF whichever is greater. MOISTURE RESISTANCE LOADING Capacitors shall be subjected to a temperature of 40±2 °C at 90 to 95% relative humidity with rated voltage for 500 Hours. After the test the samples are maintained at normal temperature and relative humidity for a period of 4 to 24 hours. When tested after this; 1. The capacitor samples shall be free of cracks, or other mechanical damages and the marking shall remain legible 2. The samples shall meet the original requirement of the Withstanding voltage 3. The samples shall meet the after test requirement of Insulation resistance as furnished in Figure 2 4. The dissipation factor shall be within 2 times the original limits 5. The capacitance change shall not exceed ±5% or ±1 pF FIGURE 3 FIGURE 2
