The CL20 Metallized Polyester Film Capacitor (Axial-Type)

The CL20 metallized polyester film capacitor is an electronic component, and its rated temperature and operating temperature range are crucial parameters for its performance and reliability. Below, I will provide a detailed description of the rated temperature and operating temperature range of the CL20 metallized polyester film capacitor:

The rated temperature of the CL20 metallized polyester film capacitor refers to the highest temperature at which the capacitor can safely and reliably operate under standard testing and operating conditions. For the CL20 model, its rated temperature is 85°C. This means that under normal operating conditions, the capacitor can withstand and adapt to an environmental temperature of up to 85°C without negatively impacting its performance and lifespan. The rated temperature is typically determined under standard laboratory testing conditions, taking into account the internal structure, materials, and design of the capacitor.

But, beyond the rated temperature, the operating temperature range is more crucial as it reflects the capacitor's applicability and stability in real-world applications. The operating temperature range of the CL20 metallized polyester film capacitor is from -55°C to 105°C. This broad range makes the capacitor highly suitable for various environmental conditions, whether in frigid polar regions or hot industrial environments, ensuring stable and reliable operation.

In low-temperature environments, capacitors need to maintain their performance and stable electrical characteristics. Low temperatures can lead to variations in capacitance values, so capacitors need to be designed and manufactured to maintain their rated capacitance. In certain applications, even at extremely low temperatures, capacitors must deliver consistent performance to ensure the accurate functionality of the circuit. Low temperatures can impact the voltage characteristics of capacitors. Capacitors need to withstand rated voltage without failure in low-temperature environments. Stable voltage characteristics are crucial for the normal operation of power supplies and other critical circuits.Under low-temperature conditions, the dielectric dissipation factor of capacitors also needs to be maintained within an acceptable range. This ensures stable performance in high-frequency applications, preventing excessive energy loss.Low-temperature environments may affect the insulation resistance of capacitors. Capacitors need to maintain sufficient insulation resistance at low temperatures to prevent charge leakage, especially for capacitors with low capacitance values.

The design of this operating temperature range considers the capacitor's application requirements in actual electronic devices and circuits. For example, power circuits, coupling circuits, and filtering circuits often face different temperature conditions, and the CL20 metallized polyester film capacitor, with its extensive operating temperature range, provides high flexibility and reliability for these applications.

So, the CL20 metallized polyester film capacitor, with its rated temperature and broad operating temperature range, ensures reliability and stability in various environmental conditions, making it an essential component in electronic circuit design.
