| VJ High Q Dielectric Vishay Vitramon Multilayer Ceramic Chip Capacitors FEATURES * COG is an ultra-stable dielectric offering a Temperature Coefficient of Capacitance (TCC) of 0 30PPM/C over the entire temperature range. * Low Dissipation Factor (DF). * Ideal for critical timing and tuning applications. GENERAL SPECIFICATIONS NOTE: Electrical characteristics @ + 25C unless otherwise specified. Capacitance Range: 1.0pF to 680pF. Temperature Coefficient of Capacitance (TCC): 0 30PPM/C from - 55C to + 125C. Dissipation Factor (DF): 0.1% maximum @ 1.0 Vrms and 1kHz for values > 1000pF. 0.1% maximum @ 1.0 Vrms at 1MHz for values 1000pF. Insulation Resistance (IR): @ + 25C and rated voltage 100,000 Megohms minimum or 1000 ohm-farads, whichever is less. @ + 125C and rated voltage 10,000 Megohms minimum or 100 ohm-farads, whichever is less. Dielectric Withstanding Voltage (DWV): 250% of rated voltage for 5 1 seconds, 50 milliamps current maximum.
