Frequently Asked Questions
What is the maximum ripple current for E50. N30-155. MK0?
The maximum ripple current is 75A at 70°C, 10kHz. At lower temperatures, higher ripple current is allowed. For example, at 50°C, the ripple current can be increased to approximately 90A using the temperature derating curve. Always verify temperature rise under actual operating conditions.
Use 75A as baseline, apply temperature derating for lower temperatures.
What mounting torque should be used for the M12 stud?
Recommended mounting torque for M12 stud is 25-30 Nm. Use a torque wrench to ensure proper tightening. Over-tightening can damage the capacitor case or threads. Under-tightening may result in poor thermal contact and overheating. Apply thermal grease between the capacitor base and heatsink for optimal thermal conductivity.
Use 25-30 Nm torque with thermal grease for optimal mounting.
