Tantalum capacitors are specialized, ultra-low equivalent series resistance (ESR) capacitors with improved offers of high stability and high capacitance per unit volume. The M39003/03-0237/HSD is a type of tantalum capacitor designed for military, aerospace, and defense applications. This capacitor has a large rated capacitance range from 1μF to 3000μF and can operate at a maximum temperature of 105°C.

The M39003/03-0237/HSD capacitor is a bipolar device and features a dual anode electrode construction. The electrode is divided into two anode portions, each having a different potassium tantalate-based solid solution, allowing for increased dielectric stability and strength. The anode is connected to the common side of the capacitor, while the other anode is connected to either ground or to the signal side of the capacitor.

The electrolyte of the M39003/03-0237/HSD capacitor is a special, non-volatile mixture of KOH and glycol mixture. The electrolyte mixture reacts with the anode in the presence of an electric field to produce the desired capacitance. Capacitance values can be adjusted by controlling the electrical field and electrolyte concentrations.

The most salient feature of the M39003/03-0237/HSD capacitor is its enhanced capacitance per unit volume. It can provide a larger capacitance than comparably-sized, traditional capacitors due to its unique anode structure and special electrolyte. This feature makes the capacitor suitable for high-end applications, such as military, aerospace, and defense.
