Tantalum capacitors can be divided into solid tantalum capacitors and wet tantalum capacitors based on structure. M39003/01-2358/TR solid tantalum capacitors are a type of non-standardized SMD (Surface Mounted Device) capacitors that are commonly used in audio-frequency circuits. They are capable of storing and releasing electrical charges and are used to store energy in pulse power applications.

The M39003/01-2358/TR capacitor is an axial lead, through-hole, tantalum solid electrolytic capacitor. It is designed to provide stable operation in a wide temperature range from -55℃ to +85℃ and is compliant with MIL-DTL-39003 standards.

The M39003/01-2358/TR will usually have a rectangular case which is made of epoxy resin and plastic. It has two pins for lead connection to the circuit. On the outer surface, there will be an anode sign for polarity identification and on the bottom, there will be a model number for identification.

The capacitance of the M39003/01-2358/TR is determined by the size of the overlying tantalum pentoxide dielectric layer and the capacitance mechanism is typically double layer capacitance. The tantalum pentoxide layer is formed on the anode by anodic oxidation. The charge Q = CV (where C is the capacitance and V is the applied voltage) is stored on the interfacial region between the anode and the anodic layer. The possibility of leakage current path also exists on the surface of the dielectric layer because of its high dielectric constant.

The M39003/01-2358/TR capacitors are relatively small in size compared to other types of capacitors, so they are suitable for applications where component volume and weight need to be minimized. The capacitance range is from 22μF to 470μF with a maximum voltage of 6.3 volts. These capacitors are very stable and reliable; they feature low ESR and ESL (Equivalent Series Resistance and Equivalent Series Inductance) values as well as excellent high frequency and temperature performance.

The M39003/01-2358/TR capacitors are mainly used for bypassing, coupling and decoupling applications in audio frequency circuits. The continuous operating temperature range is from – 55℃ up to +85℃. This makes them suitable for use in most temperature extremes. Applications include power supplies, military equipment, aircraft, and other high reliability applications.

Overall, M39003/01-2358/TR is a reliable, stable, and efficient capacitor that is well suited for a wide range of applications. It features high-frequency performance, low ESR and ESL values and excellent temperature performance. It is capable of storing and releasing electrical charges, thus making it an ideal choice for pulse power applications.
