Introduction to M39003 Series Tantalum Capacitors

The M39003 Series of tantalum capacitors are general-purpose, electrolytic capacitors used for critical avionics and instrumentation applications. These capacitors are available in a wide range of sizes, and their high capacitance ratings ensure they can be used in high-power systems. The capacitors have remarkable and stable performance in areas such as reliability, temperature coefficient, and capacitance behavior.

Application Field and Working Principle of M39003/09-0147/TR

The M39003/09-0147/TR is a type of tantalum capacitor designed to meet avionics and instrumentation requirements. It is a polarized, hermetically sealed lumped element capacitor in an axial lead configuration. The capacitor is made up of a tantalum core covered with an insulating dielectric material, and the leads are plated with gold. The electrolyte is tantalum pentoxide.The capacitor has a maximum heath range of -55°C to +125°C and an operating voltage of 16 Volts. It also has a capacitance of 1.47 microfarads with a 20% tolerance. The capacitor also provides excellent capacitance stability, tight tolerance and low impedance characteristics, making it a reliable and cost-effective solution for all kinds of demanding applications.The working principle of the M39003/09-0147/TR capacitor is based on Faraday\'s Law, which states that when a voltage is applied across a conductor, an electron flow is created. In the case of a capacitor, when a voltage is applied to its two leads, charge flows to the positive lead, leaving the negative lead deficient in charge and an electric field forms between the two plates. The more plate area, the greater the capacitor’s capacitance. When the capacitor is discharged, the charge on the positive lead is neutralized by the charge on the negative lead, resulting in zero net voltage across the plates.

Conclusion

The M39003/09-0147/TR capacitor is a reliable and economical choice for avionics and instrumentation applications. Its high capacitance, tolerance, and stability characteristics make it an ideal choice for those demanding applications. The capacitor’s working principle is based on Faraday’s Law, and its design ensures reliable and stable performance. This capacitor is an essential part of any avionics and instrumentation system.
