T540B686K004BH85107280

T540B686K004BH85107280 is a capacitor based on the tantalum - polymer technology. It is mainly used for power supply filtering and decoupling in digital and communication circuits. The product is RoHS compliant, has high current capacity and excellent electrical performance with a wide operating temperature range of -55℃~125℃. It can also offer solid reliability, a low ESR, high ripple current, and a long product life.

Working Principle

Tantalum - polymer capacitors offer the highest energy storage capacity per unit volume among solid capacitors. The electrodes are separated by a non-conductive polymer dielectric, which gives this device a very high breakdown voltage and allows for much higher capacitance values in a much smaller package. The robust construction of the capacitor makes it ideal for applications with severe shock, high vibration, and temperature ranges.

The aluminum ends are spotted by pressing the leads onto the tantalum electrodes. The pin-type contact area is tinned. The leads consist of a tinned copper wire, an annealed copper contained in a chrome layer. The negative electrode is made of pure tantalum powder, which is surface-metallized with a layer of manganese dioxide. The capacitor is then filled with an organic electrolyte. This allows the capacitor to store energy at extremely high voltages and currents, making it suitable for high-end digital devices.

Application Field

T540B686K004BH85107280 is suitable for use in various power supply and DC-DC converter applications such as high-end consumer electronics, automotive modules, mobile devices, communications equipment, power management subsystems and mixed-signal circuitry. Its high current capacity, low ESR, high ripple current, and low ESR combined with its wide operating temperature range make it an ideal choice for such applications. It is ideal for critical applications that require a reliable performance even under the toughest conditions.

The capacitor is compatible with standard through-hole, surface mount, and bottom mount configurations. It is provided with the appropriate number of pins for easy installation. The device offers excellent frequency characteristics and stress-resistant design for high reliability. The COTS (Commercial Off The Shelf)capacitor can be used in most power supply design where space is limited and performance and reliability are essential.

T540B686K004BH85107280 capacitor is also suitable for high frequency applications such as SMPS (Switch Mode Power Supplies) and high frequency DC-DC conversions. Its robust construction and high capacitance allows designers to use smaller packages and designs, allowing them to take advantage of the performance and energy storage capacity of the device and minimize design space.
