TM3E227M6R3HBA

Tantalum capacitors are a type of electrolytic capacitor, which are characterized by high volumetric efficiency, low equivalent series resistance (ESR), small size, and wide temperature range.

The TM3E227M6R3HBA is a high-frequency, low-voltage, miniaturized, tantalum capacitor. As a member of the D-pak tantalum capacitor family, it was designed for military and high-reliability applications that require low-inductance, low-ESR, and limited height. This product is also suitable for medical and automotive applications.

Application Field

This product is most suitable for applications where high-frequency performance and miniaturization are required. Its application fields include:

• Coupling and decoupling
• Bypass, filtering, and snubbing
• Power supply ripple reduction
• Timing, oscillator, and clock circuits
• RF circuit matching and tuning
• Communication lines

This device is particularly effective for noise reduction in communications lines, because of its low ESR and high frequency performance.

Working Principle and Structure

The TM3E227M6R3HBA consists of two capacitors that are connected in series in order to achieve multiple levels of capacitance with a single device. It is constructed of two independent, polarized tantalum capacitors with multiple fixed capacitances in series. The inner capacitor is the smaller one, and it has a large capacitance (usually ≥ 28µF). The outer capacitor is the larger one, and it has a small capacitance (usually ≤ 5µF).

The main principle of operation is the same as that of any ordinary capacitor: it stores an electrical charge on its plates. This charge is then discharged and supplied to the circuit when needed.

This device is suitable for use in high-frequency and high-temperature applications. It has a low leakage current and is highly reliable. Additionally, it has a low ESR, a low electrical overstress rating, and good temperature endurance. It is also shock-proof, and it has a high capacitance-voltage product.
