Tantalum Capacitors: M39003/09-0380 Application Field and Working Principle

Tantalum capacitors are among the most effective electrical components for a range of industrial and consumer applications. As such, the M39003/09-0380 is a popular choice within the tantalum capacitor range. This article will explore the application field and working principles of the M39003/09-0380.

Description of the M39003/09-0380

The M39003/09-0380 is a type of tantalum capacitor. It is a cylindrical, surface-mounted device (SMD) featuring two terminal pins. These pins are typically 18.5 mm apart for most types of the M39003/09-0380. The device can also vary in size, with product range extending from 3 mm x 6 mm to 10 mm x 16 mm. In terms of capacitance, the device is available in various values ranging from 0.47 µF to 470 µF. Its voltage rating can range from 16 volts up to a maximum of 100 volts.

Application Field of the M39003/09-0380

Tantalum capacitors provide high stability and low leakage within circuitry. As such, the M39003/09-0380 is commonly used in signal filtering and decoupling applications. One typical application of this tantalum capacitor is to provide bypassing and filtering capabilities to other components. For instance, the M39003/09-0380 can be used to filter out unwanted noise from High-Frequency (RF) oscillators. Additionally, these capacitors can also be used as a power reservoir for high-speed, high-current analogue circuits. For this application, an M39003/09-0380 capacitor should be connected directly between ground and the power node.The device is also used to supplement other components in signal conditioning chain. For instance, the M39003/09-0380 can be used in conjunction with operational amplifiers to create active filters. The capacitor should be connected between the non-inverting pin of the amplifier and ground. In other instances, the M39003/09-0380 could also be utilized as a timing element in timing circuits. In this case, a capacitor should be connected in series with a resistor to form a timing circuit. These are just a few of the application fields of the M39003/09-0380.

Working Principle of the M39003/09-0380

The working principle of a tantalum capacitor is based on electrochemical double layer capacitance, also known as electrostatic capacitance. This type of capacitance occurs due to a separation between charge within two conducting objects, such as the two terminal pins of the M39003/09-0380.The M39003/09-0380 includes an anode and a cathode. Each side of the capacitor contains a metal-oxide film, which is separated by a porous dielectric material. When voltage is applied across the capacitive plates, a layer of electrons forms on the anode. The opposite occurs on the cathode, where a layer of positively charged ions is formed. This exchange results in an electrostatic electric field, which creates a chargeable capacitor.In terms of chargeable and discharging characteristics, tantalum capacitors are effective at maintaining electrical charge. The device is capable of holding charge for a relatively long period of time, making it great for power storage applications. It is also able to release electricity at a relatively low voltage, enabling the device to function in a wide range of electrical systems.

Conclusion

As a popular choice within the tantalum capacitor range, the M39003/09-0380 features two terminal pins and is available in various sizes and voltage ratings. This device has various application fields, such as signal filtering, bypassing, and power storage. Its working principle, based on electrochemical double layer capacitance, enables the device to store electricity in a relatively stable state and release it at a low voltage.
