The capacitor for temperature compensation in power circuit is used in time-constant circuits such as Snubber-circuit and for SOFT-START. MLCC for high-dielectric constant uses Barium titanate (BaTiO3) as main material for its paraelectic. With its big relative permittivity of 1,000 to 20,000, it can be capacitor with small in size and high-capacitance. But, this material changes …
Ceramic capacitors have temperature characteristics, and capacitances are changed by temperature. There are two types of ceramic materials: temperature compensation and high dielectric constant materials, and their electrical characteristics including temperature characteristics are differ. Please see here for the details.
In a practical example, temperature compensation is used in an anemometer to ensure that the effects of air temperature fluctuations – both rapid and slow – do not compromise the linearity of wind speed measurements. Customer Service. Sales 1800 108 3888 ...
