Tantalum capacitors are widely used in a variety of electronic equipment due to their high capacitance per unit volume, excellent stability over a wide operating temperature range, low ESR, and low leakage. The M39003/01-5005/TR is an Axial Leaded Smoothing Capacitor which is ideal for use in government and industrial applications, which requires high reliability and long life. This type of capacitor offers a variety of features that make it suitable for a variety of applications, such as its high capacitance, low ESR, low leakage, and low temperature coefficient.

The M39003/01-5005/TR experiences an effective change in capacitance from -3% to +3% with a variation in temperature between 0°C and 125°C. As a result, in high temperature applications, it is recommended to use a larger size capacitor to make up for this change in capacitance. The Working voltage of the M39003/01-5005/TR is 4 VDC to 5 VDC. It is available in various capacitance values ranging from 0.2uF to 3900uF.

The basic construction of the M39003/01-5005/TR capacitor consists of a wound tantalum anode, an electrolyte, a cathode, and a continuous outer cover to form a hermitically sealed package. The anode is a tantalum pellet with an oxide dielectric, and the electrolyte is composed of grease, liquid, or solid compounds. The anode and the electrolyte form a capacitor when electrical energy is applied to the package. The cathode of the M39003/01-5005/TR is made of three layers of metal, typically including a barrier layer, a dielectric layer, and a cathode layer. The barrier layer includes materials such as molybdenum, fluorine polycrystalline oxide, lanthanum oxide, and titanium oxide, which act as an interface between the anode and electrolyte to protect the anode against leakage and voltage spikes.

The working principle of the M39003/01-5005/TR capacitor is based on the principle of dielectric absorption. When an electric charge is applied to the capacitor, the electrons from the applied electric source are absorbed in the dielectric material. This process creates a layer of electrons that builds up on the dielectric material and creates a barrier. As the capacitor is charged, the electrons spread over the surface of the dielectric material resulting in an increase in capacitance. When the capacitor is discharged, the electrons move back away from the dielectric material and the capacitance value is reduced.

The M39003/01-5005/TR is designed to meet the most stringent military and industrial requirements. It is designed with a hermetically sealed case that acts as a Faraday cage for protection from corrosion, vibration, and other external forces. The capacitor also exhibits a self-healing capability and is capable of withstanding temperatures up to +125°C. These features make the M39003/01-5005/TR capacitor ideal for applications such as power supplies, DC-DC converters, and motors.

The M39003/01-5005/TR capacitor is a reliable and cost-effective solution to a variety of military and industrial applications. Its features include a high capacitance, low ESR, and low +125°C temperature coefficient, making it ideal for a variety of applications such as power supplies, DC-DC converters, and motors. The capacitor is also designed with a hermetically sealed case that offers protection from corrosion, vibration, and other external forces.
