Frequently Asked Questions
What is the ripple current capability of CD139 10000uF/450V?
CD139 10000uF/450V has a ripple current capability of up to 15A at 85C. This high ripple current makes it ideal for inverter DC-link applications where high-frequency ripple currents are present. For higher ripple current requirements, multiple capacitors can be connected in parallel to increase the total ripple current capability while reducing the equivalent series resistance (ESR).
For applications requiring higher ripple current, consider paralleling multiple CD139 capacitors or contact our FAE team for custom solutions.
What is the expected lifespan of CD139 10000uF/450V at different temperatures?
CD139 10000uF/450V has a rated lifespan of 10,000 hours at 85C. Using the Arrhenius equation for electrolytic capacitors, the lifespan doubles for every 10C decrease in temperature. At 65C operating temperature, the expected lifespan is approximately 40,000 hours. At 45C, the lifespan extends to about 160,000 hours (18+ years).
Ensure proper heat dissipation in your design to maximize capacitor lifespan. Use our lifespan calculator for precise estimates.
What are the mounting requirements for CD139 screw terminal capacitors?
CD139 series uses M5 or M6 screw terminals depending on the specific model. Mounting torque should be 1.5-2.0 Nm for M5 and 2.0-2.5 Nm for M6. Over-tightening can damage the capacitor seal, while under-tightening may cause poor electrical contact. The safety vent should be positioned at the top (12 o'clock position) to allow proper pressure release if overvoltage occurs.
Use a calibrated torque wrench for installation and ensure proper ventilation around the capacitor for heat dissipation.
