Tantalum Capacitors

Tantalum capacitors are typically polarized electrolytic capacitors which use a metal or alloy of tantalum as the anode. They were developed in the 1950s and have since become a popular choice for many applications due to their high volumetric efficiency, excellent reliability, and low leakage current. Tantalum capacitors are available in a wide range of case sizes, styles, voltages, capacities, and temperature ranges.

M39003/03-0283H Application Field and Working Principle

The M39003/03-0283H series of tantalum capacitors are a single-ended, radial-leaded, and voltage-rated device, perfect for filtering or signal processing applications. This series is available from 1μF to 10μF in a variety of sizes and lead configurations, including single ended, dual ended, 2-lead, and symmetrical. The ESR range is 0.02Ω to 0.3Ω and the operating temperature range is -55°C to +125°C.

The working principle of a tantalum capacitor is based on the adsorption of electrolyte on the anode and cathode. The anode is made of a tantalum powder and the cathode is made of a porous material. When an electrical potential is applied to the capacitor, the electrolyte is adsorbed on the anode and the cathode by adsorption forces. This causes a physical barrier to be formed between the anode and cathode, resulting in an electrical charge being stored on the capacitive plates. The resulting capacitance of the tantalum capacitor depends on the surface area of the anode and the amount of electrolyte adsorbed on the anode and cathode.

In terms of applications, the M39003/03-0283H series of tantalum capacitors are ideal for filtering or signal processing applications where high capacitance and low ESR are required.
