Tantalum capacitors are electrolytic capacitors that are widely used in both consumer and industrial electronics because of their high volumetric efficiency, small size, and low cost. They achieve a high capacitance and are available in several different shapes and sizes. M39003/09-3046/TR is one such tantalum capacitor.

The M39003/09-3046/TR is an axial lead-type capacitor, featuring a 1uF capacitance and a 6.3V DC voltage rating. It has a very small footprint, measuring just over 10mm in length and 4.4mm in width. The pins are plated with tin and are spaced 0.24mm apart, making it easy to place and solder onto circuit boards.

The M39003/09-3046/TR consists of an anode of either sintered tantalum powder or manganese dioxide, a cathode of pure tantalum, and an electrolyte of organic solvent or dispersant. These components are assembled, connected via two leads, and hermetically sealed in a metal or molded-plastic case. The anode, cathode, and electrolyte act together to form a double-layer capacitance, alternating the electric field of one layer with the other to create a “capacitor” effect.

In operation, the M39003/09-3046/TR absorbs a charge on a level large enough to support a voltage at a predetermined level, reducing that voltage across its terminals. It will typically need to be initially charged in order for proper operation, but will maintain its charge even when disconnected from the source. The M39003/09-3046/TR is also temperature-stable, meaning that it operates at the same voltage level despite changes in operating temperature.

The M39003/09-3046/TR’s primary application lies in power-supply decoupling, where it allows the user to apply an appropriate amount of voltage to the device without having to cut power completely. It is also used as a bypass or filter capacitor, helping to bypass high-frequency signals around more sensitive components. This helps to ensure maximum reliability and reduce device malfunction. Additionally, the M39003/09-3046/TR can be used as a general-purpose pulse capacitor, enabling users to accurately store and release charge during operation.

In summary, the M39003/09-3046/TR is a small, axial lead tantalum capacitor, featuring a 1uF capacitance and 6.3V DC voltage rating. It is designed for power supply decoupling, bypassing high-frequency signals, and providing general-purpose pulse application. Its small size and temperature-stable operation make it an ideal choice for users looking for a reliable low-cost capacitor.
