Introduction

Aluminum electrolytic capacitors are an essential component in many electronic circuits. The B41896D6687M capacitor is a surface mount type aluminum electrolytic capacitor. It is a ultra-low impedance, extended life, non-polar, and offers high reliability.

Application Field

The B41896D6687M is designed for a wide range of applications, from low voltage digital circuits to high frequency switching power supplies. It is ideal for powering audio systems, electric motors, automotive electronics, medical applications, portable devices, and any other application which needs a reliable and efficient power supply. The capacitor can be used as an inductor, a filter in a power supply circuit, a multiplier, or a voltage regulator in an appliance. It can be used in high frequency or highly variable circuits, as it offers excellent high frequency performance as well as excellent spatial stability.

The capacitor has a high temperature range of -55°C to +125°C and a high ripple current rating of 1.45A. It also has a maximum operating temperature of +125°C, making it suitable for applications in harsh environments. The capacitor is highly reliable, with an MTBF of over 8,000 hours at +125°C.

Working Principle

The B41896D6687M uses the principle of electrolysis to store electric charge in an aluminum electrolyte medium. The capacitor uses two thin aluminum plates, separated by an electrolyte gel, to store electric charge. The plates are coated with an oxy-nitride film (ON film), to act as an electrical insulator and to control the leakage current. The ON film also provides a protective layer against temperature and humidity, making the capacitor suitable for long-term reliability applications.

The capacitor is charged by connecting it to an external voltage source. The positive side of the voltage source is connected to one plate and the negative side is connected to the other. This causes an electric current to flow between the two plates, allowing charge to be stored in the electrolyte gel.

The capacitor is discharged by connecting terminals to a grounded load. This causes electric charge to flow from the capacitor into the load, providing it with a voltage boost. The capacitor can also be used as an output filter, as it is able to smooth the output ripple current and provide a more stable output voltage.

Conclusion

The B41896D6687M is a surface-mount aluminum electrolytic capacitor. It is designed for a wide range of applications and is suitable for powering audio systems, electric motors, automotive electronics, medical applications, and portable devices. The capacitor has a high ripple current rating, a high temperature range, and a long MTBF of 8,000 hours. It uses the principle of electrolysis to store electric charge and is capable of providing a voltage boost.
