Film capacitors are widely used in various applications due to their excellent characteristics such as high dielectric strength, frequency stability, low temperature coefficiency, low dissipation factor, and moisture resistance. Among these, 935C2W1K, also known as metallized polyester capacitors, are a type of capacitor mainly designed to be used in high frequency circuits, where the requirements of frequency stability and dissipation factor are very important.

The main features and applications of 935C2W1K can be summarized as follows:

• Features:
• High ripple current handling capacity, up to 1.9A (RMS).
• High capacitance retention and stability across a wide temperature range.
• Very low ESR and ESL.
• High frequency stability.
• No PCB mounting required.
• Applications:
• Switch Mode Power Supplies.
• Telecommunication systems and equipment.
• DC/DC converters.
• Broadband power amplifiers.
• Power filters and noise suppressors.
• LCD displays and computer systems.

The working principle of 935C2W1K is based on the principle of static capacitance. A large static capacitance can be generated by placing two metallic plates in close proximity, separated by a dielectric layer. When a voltage is applied to the two plates, a charge is induced between them, leading to the buildup of an electric field that is proportional to the applied voltage. When the applied voltage changes, the electric field also changes, thus resulting in a change in the capacitance.

The dielectric layer used between the two plates in 935C2W1K is made of polyester film. This film offers several advantages over other dielectric materials such as low leakage current, high capacitance stability, and self-healing characteristics. It is important to note that for the self-healing process in 935C2W1K capacitors, the rated voltage must not be exceeded. Typically, the self-healing process in 935C2W1K capacitors occurs over a temperature range of between -25°C and 85°C.

In addition to the features and application of 935C2W1K, there is one more thing to consider which is the safety of this product. 935C2W1K capacitors must be used in an environment that conforms to certain safety rules and regulations. This is especially true for systems and equipment with high voltage and high currents, where explosion of the capacitor can cause serious damage and hazards.

In conclusion, 935C2W1K capacitors are an ideal choice for many high frequency applications due to its excellent features such as high dielectric strength, high capacitance retention and stability, low leakage current, low ESR and ESL, and high frequency stability. It is important to take safety precautions when using these capacitors, as their explosion can result in serious damage or hazard.
