Introduction of metallized film capacitors

  Metalized film capacitors  use organic plastic film as the medium and metalized film as the electrode. The capacitor is made by winding. The metalized film capacitors use films such as polyethylene, polypropylene, polycarbonate, etc., except In addition to the winding type, there are also laminated types, among which polyester film media and polypropylene film media are the most widely used. The role of metalized film capacitors: Capacitors of this type of metallized film have a self-healing action. It is assumed that when the tiny part of the electrode is short-circuited due to the weak electrolyte, the electrode metal around the short-circuited part will be caused by the static electricity of the capacitor at that time. Energy or short-circuit current, which triggers a larger area of melting and evaporation insulation, so that the capacitor will return to the role of the capacitor. Features of metalized film capacitors: Metallized film capacitors are vapor-deposited a layer of meta

introduction to the role of wire wound resistor

图片
  Wire-wound resistors  are made of special alloys such as constantan, manganese copper and other special alloys made into thin wires and wound on the insulating tube. There is a protective layer on the outside. The protective layer has two kinds of general enamel and moisture-proof enamel. Winding resistors are divided into two types: fixed and adjustable. Advantages of wire wound resistors: The resistance accuracy is extremely high, the noise is small when working, it is stable and reliable, the temperature coefficient is small, and it can withstand high temperatures. It can still work normally at an ambient temperature of 170 degrees Celsius. Disadvantages of wire wound resistors: The volume is large and the resistance is low, most of which are below 100KΩ. Classification of winding resistors: Wire wound resistors are divided into fixed resistors and adjustable resistors. The winding of the adjustable part of the adjustable resistor is exposed, which is not conducive to the stabilit

The difference between wire wound resistance and metal film resistance

图片
Introduction of wire wound resistance: Wire-wound resistors  are made of constantan, manganin or nickel alloy wire wound on a ceramic skeleton, with protective paint or glass glaze on the surface. There are two types: fixed and adjustable. Wire wound resistors are one of the more commonly used resistors. The resistance body of the wire wound resistor is a resistance wire. The resistance wire is wound on the ceramic frame, the lead is connected, and the surface is coated with a layer of glass glaze or insulating paint to make the wire wound resistor. Winding resistance characteristics: A: Non-flammable wire-wound coating resistors B: Can withstand high pressure shock C: Faster heat dissipation D: In a short time E: Low noise F: Resistance has not changed for many years G: The error range is small, ±5%, ±2%, ±1% H: Power range: 1/2W-10W Advantages and disadvantages of wire wound resistors: The advantages and disadvantages of wire-wound resistors include high resistance accuracy, low nois
