Tantalum Capacitors: M39003/01-7283 Application Field and Working Principle

Tantalum capacitors are a type of electrolytic capacitor composed of tantalum metal and are one of the most common types of capacitors used in electronics today. The M39003/01-7283 is a Tantalum capacitor manufactured to meet military standards. It is used in applications such as aerospace, military, and industrial, where a capacitor needs to withstand extreme temperatures, shock, vibration, and contamination. This article examines the application field of M39003/01-7283 and how this Tantalum capacitor functions.The M39003/01-7283 is a radial leaded, solid electrolytic capacitor that is small in size and provides reliable operation. It has a wide range of temperature ratings from -55°C to +125°C and can handle peak voltages up to 50V. It has a maximum capacitance of 1000µF and a minimum impedance of 100kΩ. The M39003/01-7283 is available in packages of two or four radial leads or the alternative axial leads.The M39003/01-7283 is typically used in analog and digital circuit designs requiring high ripple current capabilities and long-term reliability. Military aircraft, spacecraft, and land vehicles all use these capacitors in critical electronic design applications. These Tantalum capacitors can also be used in industrial control boards, medical devices, and medical test equipment.The basic structure of a Tantalum capacitor consists of two electrodes; an anode (positive electrode) and a cathode (negative electrode) formed from a powder and solidified in an electrolyte. The Tantalum anode is made from a sintered metal powder and is generally the most expensive element of the capacitor.The cathode of the M39003/01-7283 is formed with a manganese dioxide dielectric mix. This material provides excellent temperature and voltage characteristics and a high current capability. The dielectric used in the M39003/01-7283 is between electrodes of similar potential which creates a battery-like action between them.This action stores the charge on the capacitor and is created by the ions in the electrolyte and the electric field between the electrodes.The M39003/01-7283 has an internal ESR rating of 0.2Ω to 4Ω, with an ESR tolerance of ±25%. ESR stands for Equivalent Series Resistance and indicates the amount of resistance generated by the capacitor. The lower the ESR, the better its performance and less energy is wasted in heat, as a higher ESR indicates greater resistance and more energy is lost as heat. The M39003/01-7283 also has excellent load life and shelf life specifications compared to other capacitors.The ability to withstand extreme temperatures, shock, and vibration makes the M39003/01-7283 an ideal capacitor for military, aerospace, and industrial applications. Its compact size and high capacitance make it ideal for use in high power switching circuits and other applications requiring a large capacitance in a small package.In summary, the M39003/01-7283 is a Tantalum capacitor that is manufactured to meet military standards. It is capable of withstanding extreme temperatures, shock, and vibration and is typically used in analog and digital circuit designs, as well as military, aerospace, and industrial applications. Its internal ESR rating and excellent load and shelf life characteristics make it an ideal capacitor for a variety of applications.
