Tantalum capacitors are widely used in the electronics industry due to their unique combination of high capacitance, low leakage current, and low internal resistance. The M39003/01-8281/TR is a popular choice for use in various electronic applications. In this article, we will explore the application field and working principle of the M39003/01-8281/TR tantalum capacitor.

The M39003/01-8281/TR tantalum capacitor is an ideal choice for applications requiring a small form factor and high capacitive performance. It is widely used in low voltage a.c./d.c. circuits, telecommunication systems, industrial control systems, paging systems, airbag systems, automotive audio systems, and other similar applications. Its small size allows it to be placed almost anywhere on a PCB, and its high capacitance makes it an ideal choice for low voltage systems.

The working principle of the M39003/01-8281/TR tantalum capacitor is based on the concept of dielectric absorption. The capacitor consists of a solid dielectric material, typically tantalum pentoxide, sandwiched between two electrodes. When a voltage is applied across the capacitor, the electric field penetrates the dielectric material, causing the material to absorb energy and become polarized. The absorbed energy is stored in the form of an electrostatic field, and this gives the capacitor its capacitance.

The M39003/01-8281/TR tantalum capacitor\'s capacitance is highly temperature-dependent. Its typical value at 25°C is 828µF, but the capacitance decreases with increasing temperature. The temperature coefficient of capacitance (TCC) is -7%. This means that the capacitance decreases by 7% for every 10°C rise in temperature. This characteristic is important for applications that require reliable and stable performance over a wide temperature range.

The M39003/01-8281/TR tantalum capacitor is also characterized by its low leakage current and self-healing properties. Its maximum leakage current is typically 1µA, which is much lower than other types of capacitors. This low leakage current ensures that the device will not suffer from excessive power dissipation over time. In addition, the device has a self-healing characteristic, which allows it to recover from a mechanical overstress, leading to fewer catastrophic failures.

The M39003/01-8281/TR tantalum capacitor is a popular choice for many applications due to its small size, high capacitance, low leakage current, and self-healing properties. It is an ideal choice for use in low voltage systems, telecommunication systems, industrial control systems, and other similar applications. Its temperature-dependent capacitance and low leakage current make it an ideal choice for reliable and stable performance over a wide temperature range.
