Tantalum capacitors are capacitors that use tantalum metal for the electrodes and an electrolyte, such as an organic solvent or liquid electrolyte, to create a capacitance. Unlike other types of capacitors, tantalum capacitors have low equivalent series resistance (ESR) and extremely high capacitance values for their relatively small size. This makes them ideal for a variety of applications, including high frequency circuits, audio-frequency power supplies, and automotive electronics.

The 135D157X9030T6 is the part code of a type of tantalum capacitor often used in computing and telecommunication applications. It is a surface mount device, with its dimensions described by the code as being 1.3mm high by 5.7mm long by 9.0mm wide with a tolerance rating of 30%.

Application Field

The low profile, combined with its high capacitor-density makes the 135D157X9030T6 a great choice for audio-frequency and ultra-high frequency applications. It is also used for bypass and decoupling applications due to its extremely low ESR rating; it can also be used for coupling and power supply smoothing. Due to its high temperature rating, it can also withstand higher operating temperatures than conventional aluminum electrolytic capacitors.

The most common applications for these types of capacitors are in mobile devices and other similar high frequency signal applications. They are often employed in applications such as FM receivers, RF amplifiers, and WLAN (wireless local area network) antennas. Additionally, they are regularly used as input capacitors in high precision analog-to-digital converters and data converters.

Working Principle

Like other capacitors, the 135D157X9030T6 works by storing electrical energy in an electric field between two flat metal plates (the two electrodes). One plate is made of tantalum metal and the other image plate is made of a conductive material such as aluminum. When a voltage is applied across the two plates, an electric current is drawn from one plate and deposited on the other plate. This produces an electric field between the two plates and thus an electric charge, or capacitance. The capacitance of the capacitor is determined by the size of the plates, the distance between them, and the material properties of the electrodes.

As with other capacitors, the 135D157X9030T6 can also be used to provide bypassing and filtering functionality by forming a low-resistance/high-capacitance electrical circuit. When a voltage is applied across this circuit, the capacitance allows the electric charge to flow across it with minimal resistance, which helps reduce power supply noise, smoothing out any transients. The larger the capacitance, the better the bypassing and filtering performance.

The low ESR makes the 135D157X9030T6 ideal for high frequency and ultra-high frequency applications. Its ability to dissipate heat due to its high temperature rating is especially beneficial for these applications, making it the preferred choice in many different types of high frequency circuitry.

Conclusion

The 135D157X9030T6 is a type of tantalum capacitor that is well suited for a variety of applications due to its low ESR, high capacitance, and high temperature rating. Its small size and low profile make it ideal for a broad range of circuit designs, including audio-frequency and ultra-high frequency amplifiers and data converters. With its high capacitance and low ESR, it is also excellent for bypass and decoupling applications, as well as power supply smoothing. The 135D157X9030T6 is certainly an ideal choice for a variety of circuit applications.
