Tantalum Capacitors

Tantalum capacitors are widely used in a variety of electronic products and circuits, offering high-frequency impedance characteristics, low-ESR characteristics, and stable performance over wide temperature ranges. One of the most common types of tantalum capacitors is the M39003/01-2918H, which is a radial type of capacitor designed for high quality, reliable electronics.

M39003/01-2918H application field and working principle

The M39003/01-2918H is a radial type tantalum capacitor, primarily used for filtering applications. They are widely used in military, medical, automotive and other applications where a high-performance capacitor is required.

The type M39003/01-2918H tantalum capacitor is a surface-mount, non-polarized device with big capacitance over a wide temperature range. The capacitor provides a stable capacitance over the whole temperature range from -55°C to +105°C and a nominal capacitance of 18µF.

The Working principle of the M39003/01-2918H tantalum capacitor is the same as all other tantalum capacitors; using electrolyte to store electrical charge. A thin layer of Ta2O5 (tantalum pentoxide) is formed on the metal matrix by an anode oxidation process. A polar electrolyte is sandwiched between the anode and the cathode. When the capacitor is energized with a direct current, a positive layer is formed on the anode and the negative layer on the cathode, which separate and create two plates of the capacitor. When an alternating current (AC) is applied, the charges migrate along the capacitor plates and create an electrical field.

The M39003/01-2918H offers excellent electrical characteristics, providing high reliability and excellent capacitance stability over temperature. It is ideal for designs with a long life span, as it maintains its capacitance over temperature even up to 105°C and during ramp insertion.

The M39003/01-2918H can be used in a variety of applications, from audio and video to aerospace and military. They are reliable and offer high performance, making them an excellent choice for high-quality electronics.
