Monolithic Ceramic Capacitors have excellent temperature stability and voltage stability, and are suitable for high-precision applications. Its loss is very low, especially in high frequency applications, and it is suitable for signal filtering and noise suppression. Compared with other types of capacitors, monolithic capacitors are very small, which is convenient for the design of high-density circuits. And generally has a high withstand voltage value, and is suitable for a circuit environment with a high voltage. The monolithic capacitor has good durability and can work stably for a long time in various environments.
The voltage range of monolithic capacitor is from several volts (V) to several hundred volts (V), and the common ones are 6.3V, 10V, 50V, 100V and 250V. In low voltage applications (such as 5V and 12V circuits), monolithic capacitors with lower voltages such as 6.3V and 10V are usually selected. High-voltage applications (such as industrial equipment and HV power supply) need to choose monolithic capacitors with high withstand voltage, which are commonly 50V, 100V or higher. Some special monolithic capacitors can withstand voltage shocks as high as several hundred volts and are suitable for high voltage circuit protection. The monolithic capacitor has a wide voltage adaptation range, and the appropriate voltage level can be selected according to different application scenarios.
The capacitance of monolithic capacitor varies from several picofarads (pF) to several microfarads (μF), usually between 1nF and 10 μ f.. For high-frequency filtering and resonant circuits, it is necessary to select smaller capacitance values (such as 1nF and 10nF). Used in power decoupling, signal filtering, oscillators and other scenarios with medium and high capacitance values, such as 100nF, 1μF and 10 μ f. Some monolithic capacitors with large capacity are suitable for energy storage, filtering and other applications, and the capacity can be as high as 10μF and 100 μ f.
The working temperature of monolithic capacitors is generally between -55℃ and +125℃, which is suitable for most conventional applications. For high temperature environment (such as industrial equipment), the monolithic capacitor with high temperature resistance can be selected, and the working temperature can reach +125℃ or higher. In low temperature environment (such as cold area), the monolithic capacitor can work stably to -55℃, which is suitable for low temperature circuits. Temperature has a certain influence on the capacitance value of monolithic capacitor, and the capacitance with low temperature coefficient can reduce the influence of temperature change on the capacitance value. Monolithic capacitor can withstand high and low temperature cycles for a long time, maintaining its performance and reliability. It has a long service life, which can be used for more than 2000 hours or even longer in working environment. In high temperature environment, the life of monolithic capacitor will be shortened, but the optimized capacitor can work stably at high temperature for many years. In the low temperature environment, the monolithic capacitor can also maintain a long service life and keep a low loss. The service life in high-frequency circuits is also very good, and it can withstand high-frequency signals and work for a long time. Proper selection of suitable voltage range can keep stable performance for a long time and avoid premature damage caused by overvoltage.
Monolithic capacitors are widely used in power supply filtering, signal decoupling, noise suppression and other fields, and are commonly used in consumer electronics and industrial equipment. Because of its low ESR and low loss, monolithic capacitors are widely used in radio frequency (RF) circuits, especially for resonance, coupling and decoupling. In automotive electronic circuits, monolithic capacitors are used for power filtering, noise suppression and voltage stabilization to ensure the normal operation of electronic systems. It is used for filtering, power decoupling and voltage stabilization in mobile equipment, wireless communication and network equipment to ensure signal quality and equipment stability. In industrial control systems, machinery and other automation applications, monolithic capacitors are used for power supply regulation, signal filtering and noise elimination.
Through these characteristics and applications, monolithic capacitors play a vital role in all kinds of electronic products and circuits to ensure the stable operation of circuits.
