Aluminum electrolytic capacitors are one of the most commonly used components in a variety of electronic products, and they are mainly used in power supplies, analog circuits, and other areas. The SLP681M160C5P3 is an aluminum electrolytic capacitor manufactured by TOYECO Electronics and widely used in high-frequency applications. This article will discuss the application field and working principle of the SLP681M160C5P3.

Aluminum electrolytic capacitors consist of two electrodes with a long strip of aluminum foil wound on one side, a resin-sealed non-conductive material that separates them, and electrolytes. The negative pole is made of an aluminum sheet electrolytic anode, and the positive pole is made of a carbon film, paper, that is soaked with electrolyte. The internal aluminum foil is etched to create a large surface area. As the aluminum sheets are charged, the accumulated electrostatic charges increase the capacitance of the device.

The SLP681M160C5P3 is designed for use in high-frequency applications, such as RF circuits, audio amplifiers, and digital circuits. In these applications, its capacitance value, equivalent series resistance (ESR), voltage breakdown, surge current, and insulation resistance performance are the main aspects to consider. The SLP681M160C5P3 features a maximum capacitance of 16uF, a voltage breakdown of 6.5V, and a maximum working temperature of 125C. It also has a resonant frequency of over 100KHz, ensuring a sharp, clear audio signal.

The SLP681M160C5P3 also features low ESR performance. It has a very low internal resistance, which helps reduce energy losses generated during operation. Its low ESR also lowers high inrush currents, minimizes peak-to-peak ripple currents, and reduces audible noise. Therefore, it is also suitable for use in a wide range of switching power supplies.

In designing power supplies, the SLP681M160C5P3 allows for easy and accurate calculations of the ripple current in the output voltage. The ripple current refers to the AC component that is superimposed on the DC voltage. This ripple current is generated as the capacitor charges and discharges at regular intervals. Since the capacitance of the SLP681M160C5P3 is fixed, the ripple current can be directly calculated by using the simple equation ESR = I/2πfC, where I is the peak current, f is the frequency of the ripple current, and C is the capacitance. The ESR of the SLP681M160C5P3 is just a few millivolts, making it ideal for precise calculations of the ripple current.

In summary, the SLP681M160C5P3 is an aluminum electrolytic capacitor specifically designed for use in high-frequency and switching power supply applications. Its low ESR performance helps to reduce energy losses, while its fixed capacitance and low ESR make it an ideal choice for accurately calculating ripple currents. With its high performance, durability, and low cost, this capacitor is an excellent choice for a wide range of audio, RF, and digital circuits.
