AISHI Aluminum Electrolytic Capacitor | High Frequency Low ESR | 16V–50V | 105°C | 7000 Hours | 10µF–470µF

AISHI Aluminum Electrolytic Capacitor — High Frequency Low ESR | 16V–50V | 105°C | 7000 Hours

AISHI brand high-frequency, low-ESR aluminum electrolytic capacitors — the preferred choice for switch-mode power supply (SMPS) output filtering, audio amplifier power supply bypassing, and any application where standard electrolytic capacitors fail prematurely due to high ripple current and elevated operating temperature. The 105°C temperature rating and 7000-hour rated life (at maximum temperature) translate to decades of reliable operation at typical operating temperatures. The purple casing identifies the AISHI high-frequency series, distinguishing it from standard 85°C general-purpose capacitors. Available in 16V–50V voltage ratings and 10µF–470µF capacitance values with body dimensions matched to the capacitance.

Frequently Asked Questions

Q: What is the difference between 85°C and 105°C capacitors?
A: The temperature rating determines the maximum operating temperature and rated life. A 105°C capacitor has a longer rated life at the same operating temperature than an 85°C capacitor. In SMPS applications where the capacitor operates at 60–70°C, a 105°C capacitor will last many times longer than an 85°C equivalent.

Q: Can I replace an 85°C capacitor with a 105°C capacitor of the same value?
A: Yes. A 105°C capacitor is a direct upgrade replacement for an 85°C capacitor of the same capacitance and voltage rating. The higher temperature rating is always beneficial.
