Tantalum Capacitors - TR3B686M6R3C0350 Application Field and Working Principle

Tantalum capacitors are constructed with a tantalum core surrounded by an insulating oxide layer and an anode of metal. This construction provides a chemically and mechanically robust solution suitable for high reliability and long life applications. The TR3B686M6R3C0350 is a tantalum capacitor with excellenthigh-frequency performance and low electrical loss.

Description

The TR3B686M6R3C0350 is a tantalum capacitor with a nominal capacitance of 3.3 μF. It features a high-temperature close tolerance capacitance, excellent stability and low electrical losses, making it an ideal choice for high-frequency applications. The device is constructed with a shock absorbent, vibration resistant, non-flammable epoxy housing, and is rated for an operating temperature ranging from -55°C to +125°C, an operating voltage of 25V and a peak voltage of 35V. The device also features an on-board thermal protection mechanism and is RoHS compliant.

Application Field

The TR3B686M6R3C0350 is ideal for high-frequency applications and is typically used in computers, cell phones, automotive systems and other high-reliability applications. Its low electrical losses and high-temperature close tolerance capacitance make it an ideal choice for these applications, where accuracy and reliability are key factors. Additionally, the shock absorbent and vibration-resistant epoxy housing provides additional protection in robust harsh environments.

Working Principle

The working principle of a tantalum capacitor is based on the principle of capacitance. Capacitance is a measure of the ability of a material to store an electric charge. The capacitance of a tantalum capacitor is determined by the size, shape and permittivity of the dielectric material and the physical separation between the two plates. The TR3B686M6R3C0350 is constructed with a tantalum core, separated by an insulating oxide layer and an anode of metal. This construction provides excellent high-frequency performance and low losses. When a voltage is applied to the device, it stores energy in the form of an electric field between the capacitor plates. As the voltage across the capacitor exceeds its rated value, the electric field collapses and a small current is discharged, thereby reducing the voltage across the device.

Conclusion

The TR3B686M6R3C0350 is an excellent choice for high-frequency applications due to its high-temperature close tolerance capacitance and low electrical losses. Its shock absorbent and vibration resistant epoxy housing provides additional protection in harsh environments. Additionally, its robust construction makes it ideal for long-life applications where reliability and accuracy are key factors.
