7 Correct Use of Tantalum Chip Capacitors 1. Ripple Current and Ripple Voltage If ripple current is applied, heat is generated within capacitor by Joule s heat (power dissipation) and it may affect to reliability of the capacitor. (1) Power Dissipation The actual power dissipated in capacitor is calculated using the formula1. Where: P=I 2 ESR.Formula 1 P: power Dissipation (Watts) I: Ripple Current (Arms) ESR: Equivalent Series Resistance (Ω) Table 1 Dissipation Ratings Maximum Power Dissipation Case Code Watts,100KHz,at 25 P A B C D (2) Ripple Current Using P Max from Table 1, maximum ripple current (Arms) may be determined as follow: I= P/ESR K F. Formula 2 Where: K: Temperature Derating Factor. Table 2 F: Frequency Derating Factor Table 3 ESR: Refer to Ratings Table 2: Temperature Derating Factor Temperature Temperature Derating Factor K Table 3: Frequency Derating Factor F Type 10KHz 100 KHz 500 KHz 1MHz MnO Polymer Ripple voltage E is calculated using the formula 3. E=Z I.. Formula 3 Where: E: Ripple voltage Z: Impedance at specified frequency (3) Ripple Voltage The ripple voltage that may be applied is limited by three criteria: (a) The power dissipated in the ESR of the capacitor must not excess the appropriate value specified in 7

8 Table 1. (b) The sum of DC voltage and peak value of the ripple voltage must not exceed the rated voltage. (c) The negative peak value of the ripple voltage must not exceed the permissible reverse voltage value specified in the following section, Reverse Voltage. 2. Reverse Voltage Because the solid tantalum capacitor is of polar type, do not apply a reverse voltage to it. If reverse voltage cannot be avoided, it must be applied for a short time and must not exceed the following values: 25.10% max. of rated voltage or 1Vdc,whichever is smaller. 85.5% max. of rated voltage or 0.5Vdc,whichever is smaller 125.1% max. of rated voltage or 0.1Vdc,whichever is smaller The capacitors should not be operated continuously in reverse mode, even within these limits. 3. Applied Voltage (1) For general application, apply 70% or less of the rated voltage to the capacitor. (2) When the capacitor is used in a power line or a low impedance circuit, keep the applied voltage within 30%(50%max.) of the rated voltage to avoid the adverse influence of inrush current. (3) Derated voltage at 85 or more. When using a Chip type capacitor at a temperature of 85 or higher, calculate reduced voltage U T from the following expression. Note, however, that the ambient temperature must not exceed 125 U T =V 0 (U R U C )(T 85)/40 Where: U R : rated voltage (V) U C : derated voltage at 125 T: ambient temperature ( ) 4. Current (Series Resistance) Reliability of tantalum capacitor is increased by inserting a series resistance of at least 3Ω/V into circuits where current flow is momentary (Switching circuit, charge/discharge circuits, etc) If the capacitor is in a low impedance circuit, the voltage applied to the capacitor should be less than 1/2 to 1/3 of DC rated voltage. 5.In the Case of Short Circuit Manganese oxide tantalum capacitor (conventional tantalum capacitor) is heated and may generate fire and be burned depending upon its excess current, time and other factors. When design the circuit, provide as much margin as possible to maintain capacitor reliability. 8
