Array capacitors are electronic components that integrate multiple capacitors into a common package. This design can reduce the physical space required on the circuit board, simplify the layout, reduce assembly costs, and improve the overall performance of the system. The discharge capacity is usually composed of capacitors with the same or different values, which can be ceramic capacitors, aluminum electrolytic capacitors, tantalum electrolytic capacitors, or other types of capacitors.

characteristic:

Space saving: The capacitance reduction through shared packaging reduces the individual space required for each capacitor, thereby saving valuable circuit board space.

Simplified wiring: As capacitors are pre configured together, the wiring and design process of the circuit board can be simplified.

Improving reliability: The design of capacitance reduction reduces the number of solder joints, thereby reducing the risk of failure and improving the reliability of the entire system.

Easy for automated production: Capacity scheduling is suitable for automated SMT technology, which can improve production efficiency and consistency.

Application:

Power management: Capacity reduction is commonly used in power circuits for filtering and smoothing power signals.

Signal processing: In high-speed digital circuits, capacitance is used for decoupling and bypass to improve signal integrity.

Radio frequency (RF) circuit: In RF circuits, capacitance is used to match impedance and filter out noise.

Computers and communication equipment: Among these devices, capacity allocation is used to optimize power management and signal transmission.

Consumer electronics: In devices such as televisions, mobile phones, and audio systems, capacity reduction is used to improve performance and reduce volume.

Type:

The discharge capacity can be divided into different types based on the type and arrangement of capacitors it contains:

Single value discharge: All capacitors have the same capacitance value.

Mixed value capacitance discharge: Contains capacitors with different capacitance values to meet diverse circuit requirements.

Array capacitance: Capacitors are arranged in a matrix form, usually 2x2, 3x3 or larger.

Series/parallel capacitance: Capacitors can be configured in series or parallel to achieve specific electrical characteristics.

Package size:

The packaging size of the discharge capacitor is similar to that of a single SMT capacitor, but it is usually increased to accommodate multiple capacitors. Common packaging dimensions include:

0402：1.0 mm x 0.5 mm

0603：1.6 mm x 0.8 mm

0805：2.0 mm x 1.25 mm

1206：3.2 mm x 1.6 mm

1210：3.2 mm x 2.5 mm

When selecting capacitance, factors such as capacitance value, operating voltage, temperature characteristics, packaging size, and cost need to be considered. Manufacturers usually provide detailed product specifications and data sheets to help users make appropriate choices. Due to the wide variety of capacitance products, the most suitable capacitance product should be selected based on specific circuit design and space limitations.
