Multilayer Ceramic Capacitor (MLCC) is a widely used electronic component, which is widely used in various electronic devices due to its miniaturization, high capacity density, and good electrical performance. MLCC is composed of multiple layers of ceramic dielectric and internal electrodes stacked in a staggered manner, with external electrodes covering both ends, forming a compact capacitive structure.

characteristic:

Miniaturization: MLCC has a small volume and is suitable for high-density assembly, especially for portable and handheld devices.

High capacity: Despite its small size, MLCC can provide a wide range of capacitance values from picFaradas (pF) to milliFaradas (mF).

Low ESR (equivalent series resistance): MLCC has a lower ESR and is suitable for high-frequency applications.

Stable temperature characteristics: Some types of MLCC have stable temperature coefficients, such as COG (NPO) type, suitable for environments with significant temperature changes.

Wide voltage range: MLCC can provide a working voltage range from a few volts to several thousand volts.

High reliability: MLCC usually has good long-term stability and reliability.

Application:

Power management: used for power filtering, decoupling, and voltage stabilization.

Signal processing: used for signal coupling, bypass, and timing.

Automotive electronics: Used in various filtering and decoupling applications in automotive electronic systems.

Consumer electronics: used for miniaturization and performance improvement in devices such as mobile phones, computers, and televisions.

Industrial control: used for precise timing and signal conditioning in industrial automation and control systems.

Type:

MLCC is classified into different types based on its dielectric material and temperature characteristics, commonly including:

C0G (NPO): With zero temperature coefficient, the capacitance value remains almost unchanged during temperature changes, making it suitable for high-precision applications.

X7R: Within the temperature range of -55 ° C to+125 ° C, the capacitance change does not exceed ± 15%, making it suitable for most conventional applications.

Y5V: It has a high rate of capacitance change, but the capacitance value will significantly decrease at high temperatures, making it suitable for cost sensitive but low performance requirements applications.

Package size:

The packaging size of MLCC follows international standards, such as EIA (Electronic Industries Alliance) standards. Common packaging dimensions include:

0201: 0.02 inches x 0.01 inches (approximately 0.5mm x 0.25mm)

0402:0.04 inches x 0.02 inches (approximately 1.0mm x 0.5mm)

0603: 0.06 inches x 0.03 inches (approximately 1.6mm x 0.8mm)

0805:0.08 inches x 0.05 inches (approximately 2.0mm x 1.25mm)

1206: 0.12 inches x 0.06 inches (approximately 3.2mm x 1.6mm)

1210:0.12 inches x 0.10 inches (approximately 3.2mm x 2.5mm)

1812: 0.18 inches x 0.12 inches (approximately 4.5mm x 3.2mm)

2220:0.22 inches x 0.20 inches (approximately 5.6mm x 5.0mm)

When choosing MLCC, 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.
