Tantalum - Polymer Capacitors

Tantalum - Polymer Capacitors are designed to provide energy storage solutions and reliable support to electronic systems such as mobile phones and other portable devices. The M550B108M040TG is a series of polymer tantalum capacitors especially suited for such needs.

Application Field

M550B108M040TG capacitors have a variety of uses, primarily in portable electronics. Thanks to their small size and low weight, they are particularly suited for use in mobile phones, laptops, portable game consoles, and other handheld devices. They are also suitable for automotive and industrial applications with their ability to withstand extreme temperatures.

Design

The M550B108M040TG is a very small and slim capacitor. It measures 2.3 mm by 1.6 mm and has a height of 0.9 mm making it one of the smallest available on the market. It also has a very low leakage current of 3 μA (measured at +85 °C) and can operate reliably under extreme temperatures from -55 to +125 °C.The capacitor is designed with a cathode material consisting of solid manganese dioxide which greatly improved its long-term reliability and resistance to short circuiting.

Working Principle

M550B108M040TG capacitors are constructed with a tantalum anode and a modified organic polymer cathode. The anode is a sintered pellet of tantalum powder and the cathode is a modified organic polymer. The anode and cathode are then separated by a dielectric layer made of solid manganese dioxide which works as an insulator.When the capacitor is applied with potential, the anode receives a positive charge while the cathode receives a negative charge. The charge is stored on the capacitor until it is discharged, either via a direct connection or through a circuit.

Conclusion

The M550B108M040TG is a small, low-weight tantalum - polymer capacitor suitable for a variety of applications due to its ability to operate reliably in temperatures from -55 to +125 °C. Its use of a solid manganese dioxide dielectric layer greatly improves its long-term reliability and resistance to short circuiting. It is an ideal choice for users looking for a reliable capacitor for their portable electronic devices.
