Aishi Solid Polymer Capacitors

Solid polymer capacitors offer ultra-low ESR (10x lower than electrolytic), much higher ripple current capability, longer lifetime (no drying out), stable capacitance over temperature, and no risk of leakage. They are ideal for high-frequency applications and where reliability is critical.

Use solid polymer capacitors for high-frequency switching supplies, high-reliability applications, and where low ESR is critical.

Solid polymer capacitors offer ESR values 10-50 times lower than equivalent electrolytic capacitors. Typical ESR ranges from 5mOhm to 50mOhm depending on capacitance and voltage rating. This ultra-low ESR enables much higher ripple current capability and better filtering at high frequencies.

For applications requiring lowest ESR, select solid polymer capacitors over electrolytic.

Solid polymer capacitors offer extremely long lifetime ratings from 10,000 to 100,000+ hours. Unlike electrolytic capacitors, they do not dry out over time since they use solid polymer instead of liquid electrolyte. This makes them ideal for applications requiring maintenance-free operation over many years.

For applications requiring 10+ year lifetime, solid polymer capacitors are the best choice.

Yes, solid polymer capacitors typically cost 3-5x more than equivalent electrolytic capacitors. However, the superior performance, longer lifetime, and higher reliability often justify the cost in critical applications. The total cost of ownership may be lower when considering replacement and maintenance costs.

Consider total cost of ownership including reliability and maintenance when selecting solid polymer capacitors.

Applications benefiting most include high-frequency switching power supplies (100kHz+), computer motherboards and graphics cards, server power supplies, telecom equipment, automotive electronics, and any application where low ESR, high ripple current, and long lifetime are critical.

Use solid polymer for high-frequency, high-reliability, and critical applications.
