3 / 12 page RL - Capacitor Leakage Resistance. Typically it can be 35 K to 2.5 MOhms depending on voltage - capacitance. It can exceed 1012 ohms in monolithic ceramics and in film capacitors. Rd - The dielectric loss contributed by dielectric absorption and molecular polarization. It becomes very significant in high frequency measurements and applications. Its value varies with frequency. Cd - The inherent dielectric absorption of the solid aluminum capacitor. As frequency increases, Xc continues to decrease according to its equation. There is unavoidable inductance as well as resistance in all capacitors, and at some point in frequency, the reactance ceas- es to be capacitive and becomes inductive. This fre- quency is call the self-resonant point. Figure 4 compares the frequency response of an AO-CAP to a Tantalum chip. Maximum limits for 100 kHz ESR are listed in the part number tables for each series. Figure 4. 9. AC Power Dissipation Power dissipation is a function of capacitor size and materials. Maximum power ratings have been estab- lished for all case sizes to prevent overheating. In actual use, the capacitor's ability to dissipate the heat generated at any given power level may be affected by a variety of circuit factors. These include board density, pad size, heat sinks and air circulation. Power capability is determined based on a 20°C tem- perature rise. A higher temperature rise and therefore higher power capability is allowable as long as the ambient temperature plus temperature rise due to rip- ple current does not exceed the rated temperature of the part. Table 3 - AO Capacitor Power Dissipation Ratings 10. Ripple Current/Voltage Permissible AC ripple voltage and current are related to equivalent series resistance (ESR) and power dis- sipation capability. Permissible ripple current which may be applied is limited by two criteria: a. The resulting voltage across the capacitor with the summation of DC bias and peak voltage of the AC portion must not exceed the rated voltage of the capacitor. b. The negative peak AC voltage, in combination with bias voltage, if any, must not exceed the per- missible reverse voltage ratings presented in Section 5. Actual power dissipated may be calculated from the following: Where: I = rms ripple current (Amperes) E = rms ripple voltage (Volts) P = power (Watts) Z = impedance at specified frequency (ohms) R = ESR(Ohms) Using P max from Table 3, maximum allowable rms ripple current or voltage may be determined as fol- lows: Where: Imax = Maximum rupple current (ARMS) Pmax = Maximum Power @ allowable ∆T normally +20°C Emax = Maximum ripple voltage (VRMS) Refer to part number listings for permittable Arms limits.
