Type 550 105 °C High Ripple, Long-life, Inverter Grade, Aluminum

High Ripple, Long Life, Computer Grade

High Value, High Ripple Current

Type 550 is the original Inverter Grade capacitor for continuous

operation at up to 105 °C and it now is available in low voltages too.

For best value its load life test is 2000 hours instead of the 5000

hours of the Type 550C. While less than half the life capability of

the Type 550C, it is lower cost and easily lasts more than 10 years

in typical industrial applications.

Highlights

•ꢀ 2,000 hour load life

•ꢀ Ripple current to >50 amps

•ꢀ ESRs to 2.5 mΩ
