M39003/01-6359/TR Application Field and Working Principle

Tantalum capacitors are electrolytic capacitors that are used in many electronic circuits for smooth power supply, filtering and resonance tuning. The Tantalum capacitor has extremely short lead times and high reliability. The M39003/01-6359/TR is a small, high-energy storage three-terminal series of capacitors, manufactured to military standards. It is designed primarily for use in high-reliability, mission-critical military and aerospace applications.

The M39003/01-6359/TR capacitor series has been designed and tested to meet various environmental and electrical requirements in addition to the requirements of MIL-PRF-39003 and MIL-STD-981. To meet these requirements, the capacitors feature a sintered tantalum anode, a conformal-coated tantalum pellet with equal and opposite polarity, a monoblock housing design and an isolated electrical connection.

Unlike many other capacitor types, this type of capacitor is composed of two distinct electrodes known as an anode and cathode, and the leads of the capacitor are connected to the electrodes. The anode of this type of capacitor is typically sintered tantalum, which is relatively inert and can withstand a wide range of temperatures and voltages. The cathode is typically made of a conductive material such as silver or graphite.

This type of capacitor is commonly used in many industries, including automotive, industrial, military, and aerospace. It is used in applications that require a high level of current storage, high stability, and resistance to corrosion and temperature extremes.

Tantalum capacitors are known for their excellent storage capacity, high stability and superior electrical characteristics. The anode is composed of sintered tantalum, which is corrosion resistant and can maintain a wide range of temperatures and voltages. The cathode is composed of a conductive material such as silver, graphite or carbon, which provides high stability and superior electrical characteristics. This type of capacitor is ideal for applications that require high voltage and temperature capabilities.

The M39003/01-6359/TR capacitor series is designed to meet the highest environmental and electrical requirements. This type of capacitor is classified according to its dielectric material, temperature range, voltage range, capacitance range and other similar parameters. The capacitance range available ranges from 0.1uF to 1000uF. The temperature range of operation is from -55°C up to +125°C while the voltage range is from 4volts up to 200 volts. The tantalum capacitors have a high tolerance to temperature change and have low leakage current and excellent stability.

The working principle of these types of capacitors are relatively simple. They are typically made up of two electrodes that are separated by an electrolyte. When a voltage is applied across the electrodes, a static electric field is created which causes an ionic current to flow in the electrolytic solution. The ions that are produced by the electrolyte will form an electrical layer of charge - known as the dielectric - between the two electrodes. This dielectric layer of ions provides capacitance and allows the device to store a charge until it is discharged.

The M39003/01-6359/TR capacitors are routinely used in a variety of high-reliability, mission-critical military and aerospace applications. It is capable of delivering high energy storage, a large capacitance range and high temperature capability. This type of capacitor is ideal for applications that require high voltage and temperature capability and exceptional levels of reliability.
