Tantalum capacitors are widely used in electronic and electrical engineering applications due to their high surface area-to-volume ratio, low leakage, and low cost. The M39003/01-5145/TR capacitor, in particular, is a fairly small surface mount chip capacitor used in high frequency or RF applications.

Capacitor Construction

The M39003/01-5145/TR tantalum capacitor is constructed of two parts: a tantalum core and an epoxy mold compound. The core is made of sintered tantalum powder and the epoxy mold compound is molded around it and filled with manganese dioxide. This forms the anode, and the cathode consists of a nickel-plated steel end plate which is fused to the top of the anode. A dielectric layer consisting of a tantalum pentoxide film is formed between the anode and cathode, which allows for proper current flow.

Application Fields

The M39003/01-5145/TR capacitor is suitable for use in high frequency applications such as cellular phones, GPS systems, etc due to its small size, low leakage current, and wide range of capacitance values. Additionally, due to its reliability and low cost, it is also frequently used in power supplies, signal conditioning, memory protection, and automotive applications.

Working Principle

The working principle of a capacitor is based on the fact that when an electric field is applied to a dielectric material, a separation of charge occurs, causing positive and negative charges to accumulate on opposite sides of the material. When a voltage is applied across two conductor plates, an electric field is generated which creates a charge separation. This charge separation, known as an electric dipole, creates an electric potential between the plates. This electric potential is responsible for the capacitance of the capacitor.

Conclusion

The M39003/01-5145/TR capacitor represents the latest advances in capacitance technology. It is a versatile, high-performance chip capacitor which is ideal for high frequency and RF applications. Its capability to function reliably in extreme conditions makes it a suitable choice for a range of industrial and consumer applications.
