Tantalum capacitors are an important element in a wide range of electrical circuits and devices. A key to understanding the performance of tantalum capacitors is knowledge of the M39003/01-7109/TR application field and working principle.

The M39003/01-7109/TR device is a solid-tantalum surface-mount capacitor and is usually used in high-reliability military and aerospace applications. It has been characterized to withstand vibration and shock better than its aluminum counterparts, and is more reliable when exposed to extreme temperature changes than ceramic capacitors. It has an operating temperature range of -55°C to +125°C.

The M39003/01-7109/TR application field includes radio frequency/intermediate frequency (RF/IF) applications, microwave receiver systems, radar systems, navigation systems, and other communication systems. Its operating voltage range is 4 - 50 volts, and it is available in capacitances ranging from 0.1uF to 4.7uF.

The working principle of the M39003/01-7109/TR is one of electrical double layer capacitance. This type of capacitor consists of a capacitor element that is made up of two electrode plates with an electrolyte between them. When there is a voltage applied between two capacitor plates, an electrical double layer is formed at the electrode plate surface, forming a dielectric that separates the two layers. This dielectric is made up of ions, and their movement is responsible for the electrical charge transfer that takes place, making the capacitor function.

The capacitor’s performance depends on its design. The electrodes should be large enough to reduce the series resistance, which affects the device’s self-resonance frequency. The dielectric thickness also affects the device’s performance, and it should be chosen to suit the application. The device must also be built with special attention to the exposed metal contacts as they can cause premature failure.

The M39003/01-7109/TR is a reliable device for the application set it was designed for. It has been tested and found to meet the required military and aerospace specifications for vibration and shock resistance, as well as temperature performance.

In summary, the M39003/01-7109/TR device is a solid-tantalum surface-mount capacitor designed for military and aerospace applications. Its application field includes RF/IF applications, microwave receiver systems, radar systems, navigation systems, and other communication systems. Its working principle is one of electrical double layer capacitance, which involves two capacitor plates, an electrolyte, and an electrical double layer dielectric.

This device has been tested and proven to be reliable for its intended use, and offers good vibration and shock resistance, as well as reliable temperature performance.
