Typical Performance Characteristics www.vishay.com Vishay Sprague Solid Tantalum Chip Capacitors MICROTAN® Leadframeless Molded Capacitors 298D, 298W, TR8 and TL8 ELECTRICAL PERFORMANCE CHARACTERISTICS ITEM PERFORMANCE CHARACTERISTICS Category temperature range -55 °C to +85 °C (to +125 °C with voltage derating) Capacitance tolerance ± 20 %, ± 10 %, tested via bridge method, at 25 °C, 120 Hz Dissipation factor Limits per Standard Ratings table. Tested via bridge method, at 25 °C, 120 Hz. ESR Limits per Standard Ratings table. Tested via bridge method, at 25 °C, 100 kHz. Leakage current After application of rated voltage applied to capacitors for 5 min using a steady source of power with 1 k resistor in series with the capacitor under test, leakage current at 25 °C is not more than described in Standard Ratings table. Note that the leakage current varies with temperature and applied voltage. See graph below for the appropriate adjustment factor. Reverse voltage Capacitors are capable of withstanding peak voltages in the reverse direction equal to: 10 % of the DC rating at +25 °C 5 % of the DC rating at +85 °C 1 % of the DC rating at +125 °C Vishay does not recommend intentional or repetitive application of reverse voltage. Ripple current and Temperature derating For maximum permissible ripple current (IRMS) or/and voltage (VRMS) please refer to product datasheet and Guide to Application. If capacitors are to be used at temperatures above +25 °C, the permissible RMS ripple current or voltage shall be calculated using the derating factors: 1.0 at +25 °C 0.9 at +85 °C 0.4 at +125 °C Maximum operating voltage 298W AND TL8 RATED VOLTAGE (V) CATEGORY VOLTAGE (V) AT TEMPERATURE RANGE -55 °C to +40 °C +40 °C to +85 °C -85 °C to +125 °C 4.0 4.0 2.5 1.6 6.3 6.3 4.0 2.5 10 10 6.3 4.0 16 16 10 6.3 20 20 13 8 25 25 17 10 35 35 23 14 298D AND TR8 RATED VOLTAGE (V) Revision: 20-Jan-14 CATEGORY VOLTAGE (V) AT TEMPERATURE RANGE -55 °C to +85 °C +85 °C to +125 °C 2.5 2.5 1.7 4.0 4.0 2.7 6.3 6.3 4.0 10 10 7.0 16 16 10 20 20 13 25 25 17 35 35 23 50 50 33 Document Number: 40169 1 For technical questions, contact: [email protected] THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
