1. What materials are power filters made of?
The materials used in power filters primarily include components such as capacitors, inductors, and resistors, as well as auxiliary materials such as metal casings, connectors, and insulation materials.
Capacitors are one of the most commonly used components in power filters. Their function is to store charge in the circuit and prevent high-frequency noise from entering the power system. Common capacitor materials include aluminum electrolytic capacitors, tantalum capacitors, ceramic capacitors, and polyester film capacitors.
Inductors are another commonly used component, blocking low-frequency noise from entering the power system. Inductors are typically made of ferrite, magnetic materials, copper wire, and other materials.
Resistors are important components for controlling current and voltage and can also be used in power filters. Resistors include carbon film resistors, metal film resistors, and chip resistors.
Metal casings and connectors are typically made of metal materials such as iron, aluminum, and copper. They protect the internal components ...

Insulation materials are essential for power filters, isolating the filter from the external environment to prevent current leakage and ensure the filter's safety. Commonly used insulating materials include plastic, rubber, and silicone.

II. Precautions for Using Power Filters
1. Avoid Excessive Coating. When using power filters, be careful not to use excessively heavy surface coatings that unnecessarily reduce the effectiveness of the leads. The coating should be uniform, thin, and even to prevent these layers from reducing the cleanliness and performance of the power filter.
2. Avoid the effects of high-voltage lines. High-voltage lines can quickly affect power filters. Therefore, when selecting a power filter, consider the actual situation.
3. Avoid prolonged exposure to high temperatures and humidity. Power filters should be kept away from prolonged exposure to high temperatures and high humidity, as this may affect their performance and lifespan.
4. Avoid High Sustained Voltage. Excessive voltage across the power filter may damage its internal circuitry. Therefore, before using the filter, ensure that it is within its voltage range.
5. Avoid Overloading the Power Filter. During operation, the load on the power filter should be below its rated power range to ensure stable and safe performance.
