Its high reliability, stability, large applied voltage and relatively good temperature characteristic make it suitable for special low temperature use occasions. This article will introduce the application field and working principle of the SH221M100ST aluminum electrolytic capacitors.

Application Field of SH221M100ST aluminum electrolytic capacitors

SH221M100ST aluminum electrolytic capacitor has a wide range of applications in the field of power electronics and automotive electronics. It has a long life of up to 18000 hours and a rated voltage of 250V. It can be used in switching power supplies, inverters and battery electrolysis systems, DC power supplies and DC-AC converters in power electronics, and in automotive electronics, like starter and charging control systems, anti-lock systems, etc. The SH221M100ST aluminum electrolytic capacitor has a relatively high working voltage and a high capacity compared to other capacitors, which make it suitable for occasions with relatively long-term working environment or occasions with larger load current.

Working Principle of SH221M100ST Aluminum Electrolytic Capacitors

SH221M100ST aluminum electrolytic capacitors are made up of an electrolytically formed aluminum oxide layer, an aluminum anode base, a capacitor paper impregnated with an electrolyte solution and a lead tin bronze cathode, and most importantly, SH221M100ST capacitors are sealed with epoxy resin and rubber. The aluminum oxide layer acts as an insulator, while the paper and electrolyte solution combine under the electric field force produced by the applied voltage to form a dielectric barrier, storing energy like a traditional capacitor. The SH221M100ST capacitor can pass alternating current within rated working frequency and rapid over-voltage electric field, which makes it suitable for occasions with frequent switching.

Conclusion

The SH221M100ST aluminum electrolytic capacitors are widely used in power supplies, automotive electronics, consumer electronics and industrial electronics due to their high reliability, stability, large applied voltage and relatively good temperature characteristic. The aluminum oxide layer, paper, electrolyte and lead tin bronze are combined under high pressure, forming a dielectric barrier, storing energy like a traditional capacitor. The capacitor can pass AC rapid over-voltage electric field, making it suitable for occasions with frequent switching.
