Tantalum capacitors are some of the most versatile and popular types of capacitors available on the market today. They are small, light-weight, and cost-effective, making them ideal for a wide range of applications. The M39003/01-3189 is a specialized, non-polarized, surface-mount tantalum capacitor, designed specifically for use in high-reliability, high-temperature applications.

Application Field of M39003/01-3189

The M39003/01-3189 capacitor is primarily used in high-temperature applications, such as aerospace, medical, and automotive applications, where conditions may venture over 100°C without compromising quality. These capacitors can also perform in extreme shock and vibration environments and are well suited for down-hole drilling applications. Additionally, the M39003/01-3189 can be used in power supplies, interference filters, and energy storage circuits.

Working Principle of M39003/01-3189

The M39003/01-3189 capacitor works on the same principle as all other types of capacitors. It consists of two conductors separated by a non-conductive material, known as the dielectric. These conductors can be metal or semiconductor plates, or screened grids. When a voltage is applied across the two conductors, a charge differential is created, resulting in a stored electrical energy.

The M39003/01-3189 capacitor uses a thin layer of tantalum pentoxide as the dielectric material, which is able to significantly reduce the size of the capacitor. The conductors consist of a cathode, which is made of a high-purity tantalum wire and coated with a conductive material, and an anode, made of a high-purity aluminum metal foil.

The M39003/01-3189 capacitor also features a novel design, with an anode that features a unique “cup” shaped design, which can increase the capacitance and improve the shape retention under high temperatures. The capacitor is also hermetically sealed, which increases its reliability under extreme conditions, such as those found in down-hole drilling applications.

Benefits of the M39003/01-3189

The M39003/01-3189 capacitor offers many benefits, making it an ideal choice for high-reliability, high-temperature applications. These benefits include:

• Small size and light weight, allowing for easier integration into smaller or more complex designs
• High capacitance and reliable shape retention under extreme temperatures
• Cost-effective and long shelf life, even when operating in extreme temperatures
• Hermetically sealed design, improving reliability in harsh environments

In conclusion, the M39003/01-3189 is a specialized, non-polarized, surface-mount tantalum capacitor, designed specifically for use in high-reliability, high-temperature applications. It offers a wide range of benefits, making it an ideal choice for a variety of applications.
