Typical Performance Characteristics
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
