Frequently Asked Questions
What is the maximum ripple current?
The rated ripple current is 45A at 85C and 120Hz. This very high ripple current capability makes it suitable for large high-power inverter applications. At lower temperatures, the capacitor can handle proportionally higher currents.
For applications exceeding 45A, consider parallel connection or larger case sizes.
What is the expected lifetime?
Rated lifetime is 5,000 hours at 85C. Using Arrhenius equation, lifetime extends to approximately 20,000 hours at 65C. Every 10C reduction doubles lifetime. For detailed specifications and application support on aishi ST-220000uF-50V, refer to the datasheet or contact our team.
Operate at lowest practical temperature for maximum lifetime.
What are the terminal specifications?
This capacitor features M12 screw terminals for secure high-current connections. The terminals accept M12 bolts or screws with washers. Proper torque ensures good electrical connection. For detailed specifications and application support on aishi ST-220000uF-50V, refer to the datasheet or contact our team.
Use proper M12 hardware and torque to datasheet specifications.
What mounting is required?
This capacitor requires base mounting using the integrated mounting bracket. Mounting holes accept M12 bolts. Proper mounting ensures mechanical stability and heat dissipation. For detailed specifications and application support on aishi ST-220000uF-50V, refer to the datasheet or contact our team.
Use proper M12 mounting hardware and follow torque specifications.
What voltage derating is recommended?
Industry standard is 80% derating. For 50V capacitor, maximum operating voltage is 40V. This provides margin for voltage transients and improves reliability. For detailed specifications and application support on aishi ST-220000uF-50V, refer to the datasheet or contact our team.
