Aluminum - Polymer Capacitors

Aluminum - polymer capacitors are a type of capacitor used in a wide variety of applications, from power supply filtering and decoupling to signal processing and energy storage. The 16SVP39M is a surface-mount aluminum-polymer coin-type capacitor that is designed for use as an EMI suppression filter in automotive and other applications.

The 16SVP39M Application Fields

The 16SVP39M can be used in the automotive, consumer and industrial sectors where reliable EMI suppression is needed. It is suitable for use in a wide range of high-density, high-current applications, such as motor drive circuits, motor control circuits, DC-DC converters, and automotive instrumentation. In addition, it is well suited for filtering of high-frequency switching currents in consumer applications such as personal computers, cell phones, and other consumer electronic devices.

Working Principle of the 16SVP39M

The 16SVP39M is a surface-mount aluminum-polymer coin-type capacitor with a very small footprint. It is designed to filter out unneeded frequencies in automotive and other applications. Its working principle is based on the combination of dielectric layers and a polymer electrolyte that provides high capacitance for a given volume and size. The capacitor is also designed with a low Equivalent Series Resistance (ESR) that helps to reduce the energy dissipation in the capacitor itself, thereby increasing its efficiency.

The 16SVP39M consists of two layers of aluminum foil separated by a polymer electrolyte. A voltage is applied to the internal electrodes, which causes the aluminum foil to become polarized and creates an electric field. The electric field then causes charged ions to migrate through the electrolyte and accumulate at the outer surfaces of the aluminum foil. This creates a capacitive effect and stores energy in the capacitor.

The 16SVP39M has a rated voltage of 25V, a temperature range of -55C to +105C, and a tolerance of +20%. It also has a low self-resonant frequency of 28kHz, making it ideal for high frequency applications such as RF signal processing.

Conclusion

In conclusion, the 16SVP39M is a surface-mount aluminum-polymer coin-type capacitor designed for EMI suppression in automotive and other high frequency applications. Its working principle is based on the combination of dielectric layers and a polymer electrolyte, which provide a high capacitance for a given volume and size. The device has a low ESR to reduce energy dissipation, and a self-resonant frequency of 28kHz making it ideal for RF signal processing.
