Tantalum capacitors are valued by engineers and designers in many industries for their high capacitance/volatge ratios, higher reliability and long operating temperature range. They offer both a higher capacity and much longer life than other types of capacitors, making them an ideal choice for applications that require frequent switching.

The T551B127M050AH4251 is a tantalum - polymer capacitor which combines the features of both the electrolytic and the tantalum-capacitor technologies, resulting in a unique mix of low ESR, high capacitance and extremely high ripple current handling capability.

Application Field

The T551B127M050AH4251 is designed for high reliability applications in harsh environments, making it ideal for use in industrial, medical and military electronics. It can be used in AC and DC circuits, and its highly efficient design allows for extended run times in systems with high power demand. This particular capacitor is also suitable for use in high frequency and high temperature applications, such as power circuits for VLSI ASICs, automotive, telecom and other high speed communications equipment.

Due to its low leakage current and low temperature drift, the T551B127M050AH4251 is also commonly used in analog circuits, such as modems, ADCs and DACs. It is also widely used in digital circuits, such as gate arrays, ASICs and microcontrollers, as well as in LCD backlighting circuits.

Working Principle

The T551B127M050AH4251 uses tantalum - polymer technology, where the substrate of the capacitor is composed of an alternating layer of tantalum and polyester/polypropylene film. The tantalum layer acts as a dielectric, storing electrical charge, while the polyester/polypropylene film inhibits the migration of electrons. This combination of materials provides excellent stability and reliability.

The T551B127M050AH4251 features a low ESR (equivalent series resistance), which is due in part to its unique construction. Unlike traditional electrolytic capacitors, the T551B127M050AH4251 uses tantalum as the dielectric material, which has excellent thermal and chemical stability and does not require sprays or other treatment to stay in service. This makes the T551B127M050AH4251 ideal for use in the harshest of environments.

The low ESR of the T551B127M050AH4251 also ensures that it can handle large amounts of ripple current without needing de-rating, which is an essential feature for applications where reliability is a must. Additionally, the ESR of the capacitor is stable over a wide temperature and age range, so it can be used for long periods of time in harsh conditions.

The T551B127M050AH4251 is a great option for applications where both high capacitance and reliability are needed. Its unique construction and robustness make it an ideal choice for use in industrial, medical and military electronics.
