Tantalum capacitors, also known as tantalum electrolytic capacitors, are a type of electrolytic capacitor whose anode electrode is made from the metal tantalum, which is a rare, hard and highly corrosion-resistant element. Tantalum capacitors are polarized devices and have higher capacitance density, rated voltage and operating temperature range compared to traditional aluminum electrolytic capacitors. This makes them suitable for applications ranging from power supplies to consumer electronics, and they are widely used in a variety of consumer and industrial electronic applications. M39003/03-0172/HSD is one such tantalum capacitor series.

The M39003/03-0172/HSD series is a popular choice in a wide range of industrial and consumer applications. Common applications include transient voltage suppression, high-frequency filtering, power hold-up and UPS applications, motor control and signal conditioning, and audio and switching power supplies. The series is available in case size code J (2 mm x 0.8 mm) and case size code M (12 mm x 1.6 mm).

The M39003/03-0172/HSD series has a wide range of capacitance levels from 1 µF to 10 µF, and a broad operating temperature range from -55°C to +125°C. Rated voltage is 6.3 to 35 V and the dielectric is polypropylene. The series has excellent characteristics such as low impedance, low loss, low ESR, high ripple current, and high temperature endurance. It is available in various termination styles such as radial, snap-in, and axial leaded termination. The M39003/03-0172/HSD series can be reflow soldered and the body is rated UL 94V-0.

The working principle of a tantalum capacitor is based on the formation of an electrolytic layer on the surface of the tantalum anode. This layer that is formed is a combination of the cathode material, inert electrode material, electrolyte, and other materials that are present at the boundary between the anode and the electrolyte. When voltage is applied to the tantalum capacitor, current flows through the electrolyte and causes ions to move from the anode to the cathode, forming a thin oxide film on the anode. This forms an electric double layer that acts as a dielectric, allowing electricity to be stored in the capacitor. When voltage is reversed, the ions return from the cathode to the anode, and the capacitor is discharged.

The M39003/03-0172/HSD is an excellent choice for applications requiring a low-cost, highly reliable, and high-performance capacitor. This series offers a wide range of capacitance levels, a broad operating temperature range, and exceptional electrical characteristics. Its small size and versatile termination styles make it suitable for many different applications. Its low ESR and high ripple current allow it to handle higher current loads, while its UL 94V-0 body rating makes it a reliable choice for long-lasting service and consistent performance.
