Aluminum electrolytic capacitor selection for X-ray, CT, and MRI medical equipment power supplies. CD13HL and CD298 high-reliability series.
Selection Guidelines
Voltage Selection
Recommended operating voltage is 70%–80% of the rated voltage, which can significantly extend capacitor service life.
Temperature & Lifetime
For every 10°C decrease in operating temperature, capacitor lifetime approximately doubles.
Ripple Current
Actual RMS ripple current should not exceed 80% of the rated value. High-frequency applications require reference to the frequency coefficient table.
Capacitance Tolerance
Standard capacitance is ±20% (M grade). Special applications can provide ±10% (K grade) products.
