  • Why Ceramic Capacitors Lose Capacitance Under DC Voltage

    Ceramic capacitors are made by coating high-permittivity ceramic dielectric with metal films (usually silver), then sintering at high temperature to form electrodes. They are compact, high-capacitance, stable at high frequencies, and temperature-resistant, making them widely used in consumer elec...

  • Why Safety Capacitors Overheat and How to Prevent It

    Many electrical appliances—like TVs, fans, and refrigerators—get warm after running for a few hours. This is because electronic components, including capacitors, generate heat when powered. A capacitor is an energy storage component composed of two parallel conductive plates separated by a dielec...

  • Does Temperature Affect Ceramic Capacitor Capacitance

    Have you noticed that your phone battery drains faster in winter, or that prolonged gaming makes your phone hot and the battery depletes quickly? While many blame the battery, other internal components are also affected by temperature—such as ceramic capacitors. Ceramic capacitors are made of cer...

  • Varistor Installation Matters: Protect Your Electronics Safely

    Electronic devices rely on stable electricity for normal operation. However, during thunderstorms, voltage surges can occur. Even if lightning doesn’t strike directly, high-voltage pulses can be induced in power or signal lines. These surges are short in duration but high in energy—enough to dest...

  • Why NTC Thermistors Depend on Environment

    An NTC thermistor refers to a type of thermistor phenomenon and material in which the resistance decreases exponentially as the temperature rises, exhibiting a negative temperature coefficient. This material is a semiconductor ceramic made by mixing, forming, and sintering two or more metal oxide...
