Tantalum–polymer capacitors are a hybrid type of surface mount capacitor. This technology combines the benefits of the bulk capacitance found in tantalum capacitors with the low leakage current found in polymer capacitors, resulting in a high-performance component. The T52M1227M016C0070 is a capacitor based on this technology and is used for a variety of applications. This article explores the application field and working principle of the T52M1227M016C0070.

Uses of the T52M1227M016C0070

The T52M1227M016C0070 is used for a variety of applications, such as:

• Power supply filtering for noise and low frequency ripple attenuation.
• Decoupling between power supplies and signal and digital connections to maintain signal integrity.
• Circuit and signal switching.
• High frequency bypassing.
• RF applications, where high capacitance is needed while still maintaining low ESR.

The T52M1227M016C0070 is also often used in automotive and mobile phone applications, owing to its small size and high capacitance.

Working Principle of the T52M1227M016C0070

The T52M1227M016C0070 is based on the tantalum–polymer capacitor technology. This technology is a hybrid between the dry tantalum capacitor and the polymer aluminum electrolytic capacitor. It combines the advantages of the dry tantalum capacitor, such as high capacitance, high reliability, and long life, with the low leakage current of the polymer electrolytic capacitor. The combination results in a capacitor with higher capacitance and low equivalent series resistance (ESR).

The T52M1227M016C0070 is made using a variety of materials, including a mixture of tantalum pentoxide (as the dielectric), a tantalum matrix, a tantalum foil and a polymer resin (both as the electrodes). The capacitor is formed by depositing the tantalum pentoxide onto a tantalum matrix, which is then sintered to form a porous structure. The polymer resin is then die-stamped onto the tantalum matrix to form the top electrode.

When a voltage is applied to the T52M1227M016C0070, an electric current is generated and stored in the dielectric. This stored energy is used to sustain current flow through the capacitor when the input voltage is removed.

The rated voltage of the T52M1227M016C0070 is 16 V, and it can with high capacitance (1.2 mF) and low ESR (5 mΩmax) over a temperature range of -55°C to +125°C.

Conclusion

Tantalum–polymer capacitors, such as the T52M1227M016C0070, offer a combination of high capacitance, low ESR, and good performance in a relatively small package. This makes them ideal for applications such as power supply filtering, decoupling, and high frequency bypassing. The working principle of the T52M1227M016C0070 is based on a hybrid combination of the tantalum capacitor and the polymer aluminum electrolytic capacitor.
