The M39003/01-7287, known as the “HI-R Cap”, is a type of tantalum capacitor. It is commonly used in a wide range of applications, from consumer electronics to automotive electronics. Because of their excellent properties, these capacitors are ideal for applications that require high reliability, long life, and high ripple current.

Tantalum capacitors are made from a conductive material, usually tantalum powder, formed into a solid mass. This mass is then produced with a layer of dielectric material that forms the dielectric layer in the capacitor. Tantalum capacitors are often used as direct replacements for aluminum electrolytic capacitors in electronic circuits.

The M39003/01-7287 has an axial-leaded symmetrical construction, which reduces stray inductance and allows for a higher ripple current rating. It also has a high electrical performance, with a temperature stability of up to 20 ppm/°C and a wide range of operating voltage up to 25 VDC. The capacitance range is from 1 to 10 µF. This type of capacitor also has very low ESR (Equivalent Series Resistance) values, which make them ideal for applications in high-current, low-voltage, low-ESR circuits.

The main features of the M39003/01-7287 are their long-term stability and reliability, their high ripple current rating, and their low ESR value. These features make them well suited for applications in high-power, high-frequency electronics such as switching power supplies, DC to DC converters, and high-power audio amplifiers. These capacitors are also used in communication equipment and automobiles, both of which require reliable components in order to function properly.

The working principle of the M39003/01-7287 is very simple. When an electrical potential is applied across the capacitor, electrons are drawn to the surface of the dielectric material, creating a charge. This charge builds up until it reaches its maximum value. When the charge reaches this maximum value, the capacitor becomes fully charged and is said to have reached its capacitance. This property is known as the capacitance of the capacitor, and this is measured in Farads (F).

The M39003/01-7287 is particularly useful in high-speed and high-frequency circuits because of its low ESR value. This allows for more switching and modulation of signals without introducing undue losses to the circuit. The capacitor’s low ESR also helps to reduce conducted interference on the power line, which can significantly improve the signal quality of the system.

The M39003/01-7287 is a great choice for a wide range of applications. It has excellent performance and reliability, is well suited for high-power and high-frequency circuits, and is very cost-effective. With a wide range of available capacitance values, it is a versatile and reliable product for any application.
