Tantalum capacitors, also known as T-Caps, are special type of capacitors which rely on the characteristics of tantalum for their operation. They offer higher stability and greater reliability than standard electrolytic capacitors, making them popular for many electronic applications such as audio, medical and telecommunications. The M39003/01-7281 is one of the most popular models of tantalum capacitors, and is widely used in a variety of applications. In this article, we will look at the application field and working principle of the M39003/01-7281.

Application Field

The M39003/01-7281 is a robust and reliable capacitor offering excellent performance in most applications requiring stable electrical properties. This makes it an ideal choice for a range of applications, including

• Mobile phones and other portable electronic devices
• Audio/video signal processing and conditioning
• DC-to-DC power converters
• Automotive electronics
• Reprogrammable logic circuits
• Robotics and motion controllers

In addition, the M39003/01-7281 has been specifically designed to offer reliable performance over a wide temperature range, making it a suitable choice for use in extreme environmental conditions. This ensures that the capacitor will remain stable and reliable, even in the harshest of environments.

Working Principle

The M39003/01-7281 is a type of tantalum capacitor which operates on the principle of using tantalum as the dielectric material. Tantalum is an element which has a unique property, whereby it can store an electric charge when exposed to a voltage. This causes the dielectric material of the capacitor to become polarized, and as a result, a voltage is applied across the two plates of the capacitor. This causes a current to flow, and this current is the basis of the capacitor’s operation.

The M39003/01-7281 uses a two-terminal, cylindrical-shaped design, which makes it ideal for use in tight spaces. The capacitor is typically constructed from electroformed electrolyte, which is then encapsulated in a solid tantalum case. The case is then filled with an electrolyte solution which serves as the dielectric material. This solution is usually a combination of potassium chloride and methanol, which are both highly stable materials.

The capacitor features two separate terminals, known as the anode and the cathode. When a voltage is applied across the terminals, the anode is positively charged while the cathode is negatively charged. This causes a current to flow between the terminals, resulting in the capacitor storing an electric charge. This stored electric charge is then used to provide a steady supply of electrical current and power for the connected device.

The M39003/01-7281 also features a high ripple current rating, which is a measure of its ability to handle short bursts of high current without sustaining damage. This makes it an ideal choice for applications which require frequent, high-amplitude power surges, such as audio amplifiers. Furthermore, the capacitor’s low ESR (Equivalent Series Resistance) ensures that it does not experience significant losses when operating at high frequencies.

In summary, the M39003/01-7281 is a reliable and robust tantalum capacitor, which is suitable for a range of audio, mobile phone and automotive applications. Capable of operating over a broad temperature range, it is able to deliver reliable power even in extreme environmental conditions. In addition, its high ripple current rating and low ESR ensure that it can handle short bursts of high current and maintain steady operation even at high frequencies.
