Tantalum Capacitors: M39003/09-0063/TR Application Field and Working Principle

Tantalum capacitors are components commonly used in electronic design and production, and they are widely used in applications such as filters, timing circuits, bypass capacitors, and energy storage capacitors. The M39003/09-0063/TR refers to a type of military grade standards for specific leaded tantalum components.This metal-oxide semiconductor (MOS) capacitor is so unique because of its application field and working principle that is superior to other capacitors. It is designed for better electrical performance, power density, and stable temperature performance, in addition to its small size. This device is specified in two voltage ratings (3.3 and 4.5V) with a maximum operating temperature of 125°C.Tantalum capacitors are characterized by their capacitance, max DC voltage, ESR, polarity, and tolerance. Its technology has been applied to consumer electronic applications such as cell phones, DVD/VCR players, and data transmission, as well as automotive electronics, military, and medical applications.Tantalum capacitors are known for their excellent frequency performance. They use tantalum oxide as its dielectric, and it has a dielectric constant of about 45. The tantalum oxide is located between an anode plate and a cathode plate. The anode plate is composed of a metal or sintered tantalum Powder or slug, and the cathode plate is made of pure manganese dioxide. The plate acts as a charge carrier and is surrounded by an electrolyte. When an alternating current passes through the capacitor, the charge of the two plates transmit signals, which is responsible for its frequency performing of up to 100 KHz. Tantalum capacitors achieve an extremely low ESR (equivalent series resistance) because of its high-purity tantalum powder and electrolyte. This is because the low resistance enables the device to process large amounts of power in a short period. The M39003/09-0063/TR tantalum capacitors have a low ESR design that helps in or enhances their applications.The temperature coefficient of tantalum capacitors is positive, meaning as the temperature increases, its capacitance decreases, however, this decrease is slow, making the use of the device reliable and long-lasting. The device also offers low-resistance current paths, making it more suitable and reliable for its specified applications.The M39003/09-0063/TR tantalum capacitors possess a wide range of applications in fields such as signal filtering, noise reduction, and general timing. It is particularly suitable for d.c voltage applications, making its application field and working principle even more superior in comparison to other capacitors.The device is also designed for use in high-temperature operations and offers an overall very good reliability. It comes in two leaded versions and as both solid mica and ceramic chip packages. It has a maximum operating temperature of 125°C and a life expectancy of 40,000 hours for the solid mica package. For military application purposes, the M39003/09-0063/TR tantalum capacitors undergo several test qualifications such as a vibration test of 20 Hz to 2,000 Hz, a mechanical shock test of 40 g, and a temperature cycle test of -55°C to +125°C. This ensures that the device is functional and suitable for military-related applications. In conclusion, the M39003/09-0063/TR tantalum capacitors are metal-oxide semiconductors that are primarily used in consumer electronic, automotive, military, and medical applications. It has superior electrical performance, power density, and temperature performance when compared to other capacitors. It features low ESR, has a positive temperature coefficient, and is designed for use in high-temperature operations. In addition, the device also goes through numerous tests to ensure its quality and suitability for use in military applications.
