Working Principle

The M39003/01-7066/TR is a solid electrolytic chip capacitor with an anode composed of manganese dioxide, a cathode composed of an aluminum or stainless steel substrate, and an interior electrolyte composed of an organo-metallic formulation. The anode and cathode are separated by a porous layer of manganese dioxide.The M39003/01-7066/TR works based on the principle of an electrochemical cell in which an oxidation/reduction reaction takes place between the anode and cathode. As a result, a built-in electrical field is established between the two electrodes and an electrical charge is stored in the device. When the capacitor is connected to an alternating current (AC) or direct current (DC) power source, the anode and cathode materials interact, resulting in a capacitance value.The M39003/01-7066/TR has an ultra-low ESR, which allows the capacitor to deliver high ripple current in applications requiring very fast current changes. In addition, the capacitor offers excellent temperature characteristics and is highly reliable even in extreme temperature environments.

Conclusion

The M39003/01-7066/TR is a surface mount tantalum capacitor developed for military and industrial applications. It offers high capacitance values, excellent temperature characteristics, and ultra-low ESR. The capacitor works on the principle of an electrochemical cell, allowing it to deliver high ripple current. The M39003/01-7066/TR is used in a wide range of applications, such as space and aviation electronics, RFID tags, ordnance and missile guidance systems, avionics and navigation systems, and medical electronics.
