M39003/01-5078/TR

Tantalum capacitors are electronic components used for storing energy or acting as a buffer between a power source and a load. M39003/01-5078/TR is a type of tantalum capacitor, specifically a single anode, wrap-around chip tantalum capacitors made by popular manufacturer KEMET. This type of capacitor can be distinguished by its anode terminal which wraps around the anode body wrap.

Application Field
M39003/01-5078/TR tantalum capacitors are typically used in military and automotive electronics, computer systems, corrosion-resistant applications, and general industrial spaces. Because of their wrap-around design and small size, M39003/01-5078/TR tantalum capacitors are often used in densely populated printed circuit boards (PCBs) or surface mount devices. These capacitors can also be used in high-frequency switching power supplies and for analog signal filtering, DC-DC converters, and magnetics.

Working Principle
The working principle for M39003/01-5078/TR tantalum capacitors is the same as for any other capacitor. Electric charge is stored in a dielectric material or insulative material, in this case, the tantalum pentoxide that covers the anode of the capacitor. When a voltage potential is applied to both the positive and negative leads of a capacitor, and electric field is created across the dielectric which causes electrons to be drawn into one of the plates of the capacitor. This creates an electric charge on the capacitor’s plates which can be used to power a circuit.

The M39003/01-5078/TR tantalum capacitor has the two main components of two anode plates and a dielectric, like traditional capacitors, however, it is unique in that the wrap around anode contacts and encase the anode body wrap. The wrap-around design ensures that the anode contacts provide both electrical and mechanical connections, allowing for greater reliability and stability.

This type of capacitor also offers a wide capacitance range (0μF to 1μF) with a high tolerance (±20%), low ESR, and a high ripple current rating. The high ripple current rating is due to the larger surface area of the anode plates that comes from the wrap-around body contact and design. This offers an added protection against high temperature and makes them well suited for use in power supplies, inverters, and other high saturated environments.

M39003/01-5078/TR tantalum capacitors are particularly well-suited for military and automotive applications who may also require special features such as high capacitance, low impedance, and low temperature coefficient. Additionally, these capacitors are Reflow and Drop Solder compatible, making them easy to integrate into existing electronic designs.

In summary, M39003/01-5078/TR tantalum capacitors offer high capacitance, low impedance, and low temperature coefficient as well as superior mechanical and electrical connections due to their wrap-around body designs. As such, these capacitors are an ideal solution for high frequency switching power supplies and other military and automotive applications where reliability and durability are of paramount importance.
