Tantalum capacitors are used in a wide variety of applications due to their high reliability, low leakage, high capacity, and relatively small size. The M39003/01-7104H is a type of polymeric tantalum capacitor that is especially useful for its long-term reliability and ultra-low leakage characteristics. It is well-suited for applications in power supplies, medical equipment, aerospace, and even consumer electronics. In this article, we will explore the application field and working principle of the M39003/01-7104H.

The M39003/01-7104H is a surface-mounted ceramic chip capacitor that has a minimum capacitance of 0.1 µF and a maximum capacitance of 4700 µF. Its ESR (equivalent series resistance) is typically < 0.15Ω to < 0.60Ω, depending on the capacitance and temperature coefficient characteristics of the device. The M39003/01-7104H is designed for use in high-reliability applications, such as those found in power supplies, computers, and medical equipment, where its high-reliability and low-ESR characteristics are most beneficial.

The M39003/01-7104H belongs to the family of tantalum capacitors, which are among the oldest and most reliable technologies used in the electronics industry. Tantalum capacitors are constructed from a polaron or “sandwich” of tantalum oxide and manganese dioxide materials that are sandwiched between two metal layers. The electrical energy stored in a tantalum capacitor comes from a chemical reaction between the two materials. When the capacitor is discharged, the chemical reaction reverses itself and the electrical energy is released.

The M39003/01-7104H is an especially reliable version of this type of capacitor. It is constructed using advanced anode and cathode materials that are optimized to reduce stress-aging effects, ultimately leading to longer capacitor life and improved performance. The M39003/01-7104H includes a variety of features to improve its reliability, such as: a superior dielectric layer, improved chip manufacturing processes, silver and silver alloys as the anode contacts, and a three-contact pad configuration that helps to reduce ESR.

The M39003/01-7104H is also designed to withstand temperature extremes, having an operating temperature range of -55°C to +125°C. This extended temperature range means that the capacitor can be used in a wide variety of applications, from high-reliability, high-temperature aerospace and medical applications to consumer electronics.

In conclusion, the M39003/01-7104H is an extremely reliable version of the polymeric tantalum capacitor that is designed for use in a variety of high-reliability and high-temperature applications. It offers excellent capacitance, very low ESR, and an extended temperature range that ensure that it can be used in many applications. With its advanced materials and manufacturing processes, the M39003/01-7104H is an excellent choice for any application that requires a very reliable and high-performance tantalum capacitor.
