Tantalum capacitors are a type of capacitor commonly used for their small size, large capacitance-to-volume ratio, good stability, and improved electrical characteristics. The M39003/01-5117/TR is one such type of capacitor and is used primarily in applications requiring high ripple current capacity and low effective series inductance.

The M39003/01-5117/TR is a leadless, surface-mount tantalum capacitor. It has a wide range of capacitance ratings from 1 - 1,200 microfarads, making it suitable for a wide range of applications. It is a solid-electrolyte device, meaning it has an oxide-based capacitor element. The capacitor is encapsulated in a rigid, hermetically sealed epoxy resin shell, providing excellent environmental protection against shock, vibration, and other harsh conditions.

The main features of the M39003/01-5117/TR capacitor are its high ripple current capacity and very low effective series inductance (ESL). These two features are important for applications where there is heavy switch and engine noise. The capacitor also provides low ESR and self-healing, which help to ensure a long life for the capacitor. Additionally, the capacitor’s low ESR and ESL allow for good efficiency in power conversion applications.

The working principle of a tantalum capacitor is fairly simple and is similar to that of other types of capacitors. In a tantalum capacitor, a metallic film is sandwiched between two layers of oxide material. The metal film is the capacitor’s “plate” and the two layers of oxide material act as the dielectric. When an electrical voltage is applied across the capacitor, the metal film absorbs a layer of positive ions, creating a capacitance. This causes the capacitor to store electrical energy and release it when the voltage is removed. This process is reversed when the voltage is reversed.

The M39003/01-5117/TR application field is broad, as the capacitor has a wide capacitance range and good electrical characteristics. It is used in power supplies, military avionics, DC-DC converters, and switching circuits. The capacitor is also used for filtering applications, often due to its low ESL and ESR. Additionally, it is used in audio systems, instrumentation, medical equipment, and automotive electronics.

The M39003/01-5117/TR is a reliable and widely-used type of tantalum capacitor offering excellent electrical performance and environmental protection in a variety of applications. It is a miniature, surface-mount device with a wide range of capacitance ratings, making it well-suited to many different applications requiring good power conversion efficiency, low ripple current capacity, low ESL, and reliable environmental protection.
