SMD capacitor material specifications: SMD capacitor currently use different material specifications such as NPO, X7R, Y5V, etc. Different materials have different uses.
NPO SMD capacitor
It is the most commonly used monolithic ceramic capacitor with temperature compensation characteristics. Its filling medium is composed of rubidium, samarium and some other rare oxides.
When the temperature is from -55℃ to +125℃, the capacity change is 0 + 30ppm/C, and the change of capacitance with frequency is less than + 0.3△C. Drift of NPO SMD capacitor
Or the hysteresis is less than ±0.05%, which is negligible relative to film capacitance greater than ±2%. Its typical capacity has a relatively large change of less than ±0.1%.
NPO SMD capacitor are packaged in different forms, their capacitance and dielectric loss
NPO capacitor are suitable for tank circuit capacitor of oscillators, resonators, and parallel capacitor in high-frequency circuits.
