M39003/01-5346/HSD Application Field

The M39003/01-5346/HSD capacitor is designed specifically for commercial integrated circuit applications. These capacitors are used primarily in portable and wearable electronic products, and medical, handheld, and consumer applications. It can also be used in cars, military equipment, and instrumentation. This component is ideal for applications that require high operating temperature (up to +125°C) and vibration levels, and in circuits with limited space.

M39003/01-5346/HSD Working Principle

The M39003/01-5346/HSD utilizes a tantalum anode and a manganese dioxide cathode. The tantalum anode consists of a metal wire core and a tantalum oxide outer layer. The metal wire core "stores" the charge while the outer layer acts as a dielectric barrier. The manganese dioxide cathode acts as an electronic conductor to the anode. The capacitor structure is filled with dielectric electrolyte which allows the electrical current flow between the electrodes.When a voltage is applied, the amperage initially increases rapidly. This is because the dielectric barrier formed by the tantalum oxide helps to reduce the capacitance. As the voltage increases, the capacitance decreases, eventually reaching a steady state wherein the capacitance is constant. As soon as the voltage is removed, the charge stored in the device dissipates rapidly and the capacitance decreases to near zero.

Conclusion

The M39003/01-5346/HSD is a molded chip capacitors specifically designed for commercial integrated circuit applications. Its unique structure offers superior performance, with excellent electrical performance at temperatures up to +125°C, and vibration-resistant quality. Its ability to handle high-temperature and vibration levels makes it an ideal choice for a variety of applications, from consumer products to military equipment. Its working principle combines the use of a metal wire core and tantalum oxide outer layer, and a manganese dioxide cathode, to store charge efficiently and achieve a steady capacitance.
