Introduction to Tantalum CapacitorsTantalum capacitors are electrical components with a high energy storage capacity made of a dielectric material of tantalum oxide. They are useful for a wide range of applications where a relatively small amount of energy needs to be stored temporarily. In the past, the use of tantalums was limited to specialist applications, but today they are commonplace in consumer devices such as laptops and mobile phones.M39003/09-2028 Application Field and Working PrincipleThe M39003/09-2028 tantalum capacitor, developed by Vishay, is a high-stability device designed forMilitary and commercial applications. This capacitor features a wide range of working voltage and capacitances, making it suitable for a variety of applications. It is particularly well-suited for use in high-reliability systems including Aerospace, down-hole equipment for the oil and gas industry, nuclear power control systems, and automotive products.The M39003/09-2028 has two main components: an anode (or “positive”) terminal and a cathode (or “negative”) terminal. When a voltage is applied between these two terminals, an electrostatic field is created between them. This field allows electrons to move from one terminal to the other, resulting in an electrical charge being stored within the device. When the voltage is removed, the trapped electrons are released back into the external circuit, resulting in a discharge of energy.The M39003/09-2028 offers a wide range of capacitance values spanning 0.004μF to 33μF, and a practical working voltage range of 16V DC to 50V DC. The ultra-stability of this device has been rated at up to 5% over a temperature range of -55°C to 125°C. Additionally, its low internal resistance and excellent leakage performance make it suitable for high-reliability, low-power applications. The small size of the M39003/09-2028 makes it ideal for use on space-constrained circuit boards.ConclusionIn conclusion, the M39003/09-2028 tantalum capacitor is a high-stability device with a wide range of working voltage and capacitances, making it suitable for a variety of applications. Its small size and excellent leakage performance make it ideal for space-constrained circuit boards. This capacitor is an excellent choice for use in high-reliability applications such as Aerospace, down-hole equipment for the oil and gas industry, nuclear power control systems, and automotive products.
