Tantalum Capacitors: M39003/01-7334/TR Application Field and Working Principle

Tantalum capacitors are high-energy density surface-mount components used across a wide outlet of electronic devices, including computers, cameras and other consumer electronics. This capacitor type has been around since the late 1950’s, and continues to be popular today. The M39003/01-7334/TR tantalum capacitor is a popular choice, and is known for its low form factor and superior performance. This article will discuss the application field for the M39003/01-7334/TR and its working principle.

Application Field

The M39003/01-7334/TR is a Surface Mount Device (SMD) that is designed to sit on the surface of a printed circuit board. It is a relatively small capacitor, measuring just 0.08”x 0.04” or 0.2 x 0.2mm, yet still providing a respectable capacitance of 0.47µF. These attributes make the M39003/01-7334/TR ideal for a variety of small electronics and consumer products, including digital cameras, cordless phones, webcams, and GPS systems. The small form factor also makes it suitable for the electronics on portable/wearable devices, such as fitness trackers and smart watches.

The M39003/01-7334/TR is also popularly used in integrated circuits, especially for devices that require a large amount of power for a short period of time. This capacitor type is also useful for suppressing electrical noise and smoothing out current vibrations. Other applications for this type of capacitor include signal filtering, pulse applications, and boosting power.

Working Principle

The operation of the M39003/01-7334/TR is based on the variation in electric fields and capacitance when two conductors are placed in close proximity. In a capacitor, two parallel conductors are electrically separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field forms in the dielectric material, creating a capacitance between the two conductors. This capacitance is measured in Farads (F), the unit of capacitance.

In the M39003/01-7334/TR, 0.47µF of capacitance is achieved via the use of a solid tantalum electrolytic dielectric. This is the most efficient way of producing a high-capacitance and low-profile device, and it also ensures a long capacitor life and a high energy density. Furthermore, the device is rated for high-temperature operations, making it suitable for highly demanding applications such as those found in computers and consumer electronics.

Other features of the M39003/01-7334/TR include its capacitance tolerance of ±20%, a maximum working voltage of 25V, and withstand voltage of 35Vdc. The capacitor is also RoHS-compliant, meaning it is free of hazardous substances, such as lead and mercury. This allows it to be used in a variety of applications, including those involving sensitive circuits.

Conclusion

The M39003/01-7334/TR tantalum capacitor is a popular choice for a wide array of consumer and professional electronics. It is a small and efficient component with a rated capacitance of 0.47µF, a high withstand voltage of 35Vdc and a maximum working voltage of 25V. Its use of a tantalum electrolytic dielectric ensures reliability and a long life, while its RoHS-compliant construction permits safe use in sensitive circuits. All these features make the M39003/01-7334/TR an ideal capacitor for any number of applications.
