Capacitor Networks and Arrays

The W3A4YC104MAZ2A is a capacitor network consisting of four ceramic surface mount capacitors of 10,000pF each in a 0402 case size and a 2A working current. It is ideal for space-constrained device applications, as well as higher-density products where voltage holds a particular significance. This network provides an outstanding solution in areas, such as automotive, where capacitance stability and assured space savings are utmost important.

A capacitor network is a set of capacitors that are connected together in a certain configuration such that they can provide a range of electrical parameters. The W3A4YC104MAZ2A is a combination of four identical 10,000pF/0.5V ceramic surface mount capacitors of 0402 case size with its own lead frame for lower ESR and better performance at high frequencies. The four capacitors are connected in series and feature two terminals, with the upper terminal being the ‘common’ terminal, and the lower terminal being the ‘ground’ terminal.

Working principle of the W3A4YC104MAZ2A

The W3A4YC104MAZ2A uses its four capacitors to filter out high-frequency pulses and transient voltages generated by circuits by making them bypass the existing power source. By decreasing the amount of power consumed by the connection, the network can be used to reduce overall system power consumption. This power reduction improves the efficiency of the product while ensuring reliable energy delivery. In addition, the network acts as a decoupling device by reducing undesired noise levels that can interfere with the signal integrity of connected components.

In designs where higher capacitance values need to be reached, several networks can be connected in parallel, forming an array. This is commonly known as a capacitor array. The configuration of these arrays can vary, providing different electrical parameters such as capacitance and impedance values. The capacitance of a capacitor array can be calculated by adding up the capacitances of all the discrete capacitors, and the impedance is determined by the configuration the array.

Applications of the W3A4YC104MAZ2A

The W3A4YC104MAZ2A is used primarily in automotive applications because of its high current carrying capacity and excellent characteristic of high-frequency noise isolation. In automotive systems, the network is helpful in avoiding potential damages that can be caused by high-frequency electromagnetic pulses or currents. It is also used in various consumer and industrial electronics to reduce voltage levels and protect sensitive components against high-frequency pulsed and transient voltages.

The W3A4YC104MAZ2A is specifically useful in higher-density products where voltage holds a particular significance, such as in RFID systems. Its excellent performance at high frequencies without changing capacitance values is essential to achieve reliable and accurate data transmission in such applications. Besides, the network provides outstanding temperature-drift performance and very low inductance, ensuring stable response at different temperatures.

In summary, the W3A4YC104MAZ2A capacitor network offers an ideal solution for high-density applications where space constraints are an issue. Together with the fact that it has excellent high-frequency noise isolation, temperature stability, and low inductance and lead frame for lower ESR, the network provides superior functionality for many applications.
