Tantalum Capacitors

Tantalum capacitors, also known as Ta capacitors, are widely used in many applications such as filters, power supplies, circuit protection, and timing. They are known for their high reliability, excellent electrical characteristics, and low ESR (equivalent series resistance). They are particularly well suited to applications where size and cost are major factors.

M39003/09-2037/HSD Application Field and Working Principle

The M39003/09-2037/HSD is a tantalum capacitor designed for use in signal and power supply circuits. It is a surface mount device with a high dielectric and temperature coefficient. The rectangular tantalum capacitor has 4 contacts each side, with a single pad in the center. This design allows for easy assembly and provides reliable impedance and low self-inductance.

The M39003/09-2037/HSD is designed to meet a variety of requirements for applications where size and cost are critical factors. It has an insulation resistance of up to 4,000 ohms, and offers an excellent temperature coefficient of -0.12%/°C. It also has an ESR rating of 0.02 ohms and can handle a maximum voltage of 6.3VDC.

The working principle of the M39003/09-2037/HSD is as follows: the two contact surfaces are connected to two separate conductors which form a continuous loop. This in turn creates a capacitor whose term of operation relies on the charge stored in the dielectric. When a voltage is applied to the capacitor, the dielectric absorbs the charge from the conductors, and a current flows through the capacitor. This creates an alternate current across the capacitor, which is also known as a capacitive reactance.

The amount of resistance offered by the capacitor to the alternating current is a function of its capacitance, and this value is indicated by the capacitor\'s ESR rating. The higher the ESR rating, the greater resistance the capacitor offers to an alternating current, which in turn increases the capacitor\'s impedance.

The M39003/09-2037/HSD provides excellent performance and reliability in a wide range of operating environments. Its low ESR and low self-inductance allow it to perform well in high frequency applications, while its high insulation resistance and temperature coefficient make it suitable for applications with varying temperatures. Furthermore, its small size and cost-effectiveness make it suitable for applications where size and cost are major factors.
