Tantalum Capacitors

Tantalum capacitors are among the most reliable and popular of all the different types of capacitors available today. They are based on an electrode consisting of a tantalum powder mixed with a manganese dioxide dielectric. This combination produces a capacitor that can have a temperature coefficient ranging from +200 ppm/K to -50 ppm/K. The M39003/01-7289 is an excellent example of a tantalum capacitor.

The M39003/01-7289 is a non-polarized surface-mount tactical tantalum capacitor with a capacitance of 35μF. It has a rated voltage of 10V and a maximum impedance of 5 Ω at 100 kHz. The M39003/01-7289 comes in a standard EIA size of 7289 series and is designed for use with most printed circuit board (PCB) materials. It is RoHS compliant and is certified to last 10,000 hours at 125°C.

Application Field

The M39003/01-7289 is mainly used for decoupling applications, as power supply filtering, or as part of a noise suppression system. The capacitor’s low impedance and high capacitance make it ideal for these tasks. The 35μF capacitance value means that the capacitor can store more charges than smaller capacitors, making it an effective filter for removing any unwanted noise that could affect the circuit’s performance.

The M39003/01-7289 is also widely used in microprocessor operations, such as CPU timing and memory interface synchronization. It is capable of providing fast transient response times, making it well suited for these types of applications.

Working Principle

When a voltage is applied to a capacitor, it causes the charged particles to shift between the two electrical plates of the device. This charge imbalance creates an electrical field between the two plates, which stores energy. When the voltage is removed, the electrical field dissipates and the capacitor is discharged. This is the same principle that enables the M39003/01-7289 to store and release energy.

In addition to this basic principle, the M39003/01-7289 is designed to be non-polar, meaning that it can be polarized in either direction and will still work properly. This makes it ideal for applications where the voltage polarity is unknown or changes frequently. The capacitor also has a low ESR, which makes it more effective at handling high frequencies.

Conclusion

The M39003/01-7289 is a robust and reliable surface-mount tantalum capacitor that is well suited for a wide range of applications. It is designed to operate at high temperatures and has a low ESR, making it an ideal choice for microprocessor operations and decoupling applications. Overall, the M39003/01-7289 is a great option for those looking for a quality capacitor.
