Tantalum - Polymer Capacitors

Tantalum - Polymer Capacitors are capacitors that are characterized by their high capacitance density and low profiles, being uniquely compact in construction. They are known for their ability to be placed in tight locations, and their low profile makes them suitable for applications that require space-efficiency. They are also highly reliable and temperature stable — especially when compared to other capacitor types — and possess superior temperature behavior. One such type of capacitor is the T551B686K030AH.

T551B686K030AH Application Field

The T551B686K030AH capacitor is especially suited for use in notebook computers and mobile phones due to its low profile, high efficiency, and superior temperature stability. Its RoHS compliant construction and long life also make it a top choice for several high-end applications in the industry. It is frequently used as an input filtering capacitor for power supplies, pulse-width modulation (PWM) switching power supplies, and DC-DC converters.

T551B686K030AH Working Principle

The working principle of the T551B686K030AH capacitor is similar to that of any other capacitor; however, it uses either a solid-state polymer or a conductive organic film (sometimes called solid polymer) as its medium. This construction creates a low-resistance electrical path between two electrodes. The path created by the two electrodes will then cause a circuit to capacitate by storing electrical charges between them.

Operating Characteristics of the T551B686K030AH

The T551B686K030AH capacitor offers numerous operating characteristics that give it an advantage over other capacitors. These capabilities include excellent ripple current capability and temperature behavior, low dissipation, superior charge and discharge characteristics, low ESR (Equivalent Series Resistance), high capacitance-voltage ratio, and a long product life. All these characteristics make the T551B686K030AH an ideal choice for power supplies, PWM converters, and DC-DC converters.

Conclusion

The T551B686K030AH capacitor offers numerous advantages over other capacitors, including excellent capacitance density and low-profile construction, space-efficiency, highly reliable and temperature stable performance, and superior temperature behavior. It is well-suited for use in notebook computers, mobile phones, power supplies, PWM switching power supplies, and DC-DC converters due to its RoHS compliant construction and long life. Its operating characteristics are also superior, boasting excellent ripple current capability, low dissipation, and a long product life, with a high capacitance-voltage ratio and a low ESR. Overall, its versatility as a component makes it a top choice for a wide variety of applications.
