Introduction of Aluminum - Polymer Capacitors

Aluminum - Polymer Capacitors are a special type of capacitor designed to provide high capacitance and low impedance in harsh environment. They are primarily used in audio and power applications, providing good heat dissipation and withstanding high mechanical strain. The major components include aluminum-polymer, electrolyte and solder bodies. Aluminum - Polymer Capacitors possess several advantages over standard capacitors. They are highly reliable and efficient, are able to withstand high temperatures and mechanical strain, and are generally more resistant to failure than standard capacitors. In addition, they can provide higher capacitance values than their ceramic Counterparts.

The 277UER016MFH Capacitors

The 277UER016MFH Aluminum-Polymer Capacitors are a type of aluminum-polymer capacitors specifically designed for audio and power applications. These capacitors have a capacitance of 200 µF and a voltage rating of 16V. The capacitors are encased in Epoxy resin, sealed and RoHS compliant, making them one of the most rugged and reliable on the market.The 277UER016MFH aluminum-polymer capacitors offer increased power efficiency and improved heat transfer compared to standard capacitors. Their dielectric is an organic electrolyte impregnated in an aluminum core. This organic electrolyte provides higher power efficiency than standard electrolytes, resulting in lower impedance and better heat dissipation. Additionally, the solid resin construction helps protect against failure in harsh conditions.

Application Field & Working Principle

The 277UER016MFH aluminum-polymer capacitors are primarily used in audio and power applications, such as, power supplies, switch-mode power supplies and audio amplifiers. They provide high capacitance, low impedance and the capability to withstand high temperatures and mechanical strain.When used in audio or power applications, the capacitors are connected between two nodes of the circuit. When power is applied, the capacitor acts as signal filtering, reducing high frequency noise and providing a low impedance signal path. The aluminum-polymer creates a high barrier between the two nodes and thus, reduces the amount of transition time between on and off signals. This helps reduce the amount of power lost to heat and thus, increases power efficiency.In addition, the capacitors are capable of operating at temperatures up to 105°C and feature higher capacitance values than their ceramic counterparts. This makes them ideal for high power application as they can provide high capacitance values at a much lower temperature.

Conclusion

The 277UER016MFH Aluminum-Polymer Capacitors are specifically designed to provide high capacitance and low impedance in power and audio applications. Their construction helps protect the capacitors from harsh environment and the organic electrolyte helps reduce power losses. Additionally, the capacitors can withstand temperatures up to 105°C and offer higher capacitance values than ceramic capacitors.
