Tantalum Capacitors

A tantalum capacitor is a type of electrolytic capacitor, a component of electronic circuits. It consists of a pellet of tantalum metal as an anode, covered by an insulating oxide layer that forms the dielectric, surrounded by liquid or solid electrolyte as a cathode. These capacitors are especially valuable in applications requiring a very small amount of capacitance such as in hybrid microcircuits, allowing for a very compact assembly due to their small size.

Application Field

The M39003/09-3080/TR is a family of miniature tantalum capacitors specifically designed for hybrid microcircuits. The type of capacitors are ultra-small, non-standard, low ESR, and high CV value, making them ideal for applications requiring a limited amount of capacitance or a space crunch. This capacitance can be used in various circuit designs such as audio signal processing, filter networks, power relays, relays, and ignition systems.

Working Principle

The M39003/09-3080/TR works through a dielectric material inserted between an insulating layer and a conductive metal. Under normal operation, the field created by the applied voltage attracts electrons from the negatively charged electrolyte and causes them to accumulate on the anode, the positive side of the capacitor. The charge is accredited against the negative charge of the dielectric material and its reverse voltage. This reaction creates a capacitance, the basic property of a capacitor, which is then used for various applications.

The design of the M39003/09-3080/TR optimizes the space requirement and overall electrical performance of the device. The optimized size and shape of the leads and the dielectric type contribute to the efficient transfer of the charge to the capacitor allowing for higher power density with low ESR and stable capacitance that remain within tight tolerance limits. This design makes it a great choice for hybrid microcircuits that require only a small amount of capacitance.

Conclusion

The M39003/09-3080/TR family of capacitors is designed to offer superior electrical performance in small, hybrid microcircuits requiring only a limited amount of capacitance. These capacitors offer ultra-small size, low ESR, high CV value, and stable capacitance within a tight tolerance range. This design makes them an ideal choice for applications that require small size, but high efficiency.
