Blue and white adjustable potentiometers are usually called blue and white adjustable resistors or blue and white variable resistors. Different people call it differently, but the actual things are the same. The reason why it is called the blue and white adjustable potentiometer is because the product color of this kind of potentiometer is blue and white, and the appearance is very beautiful. Because of the bright color, the blue and white adjustable potentiometer package is also better than the package of the ordinary potentiometer. More refined.
Principle of blue and white adjustable potentiometer:
Principle 1.Resistor body: The resistor body is a resistive component that supplies a certain resistance value in the blue and white adjustable potentiometer. Its electrical function can determine the main electrical function of the blue and white adjustable potentiometer. The resistor body should have good resistance stability, small resistance temperature coefficient and static noise.
Principle 2. Frame and substrate: The frame is the insulating support of the blue and white adjustable potentiometer resistor. The frame and matrix are usually made of materials with good insulation properties, which require good heat resistance, electrical insulation, moisture resistance, thermal conductivity and chemical stability.
Principle 3. Brush, sliding Q and center contact ring piece: The moving contact component that slides along the resistor body in the blue and white adjustable potentiometer and leads to the input voltage is called the brush or the contact input brush, which is divided into carbon brush and Two kinds of metal brushes. Metal brushes are brushes made of metal materials. The carbon brushes are made of mixed materials such as carbon and resin. Conical and rectangular brushes. The blue and white adjustable potentiometer has low contact noise, mechanical durability and durability. Reliability and service life are directly related to the contact state and mechanical wear of the brush-resistor body.
• High withstand voltage, able to withstand overvoltage 1.5 times the rated voltage
• The medium loss is small, the ESR is small, the internal temperature rise of the product is low, and the temperature characteristic is good
• Small size, long life, no acid pollution
• Can be stored for a long time
• Ability to withstand high effective current, up to 1Arms/μF
• No polarity, can withstand reverse pulse voltage for a long time
• Alternative electrolysis is not an equal capacity substitution, but a functional substitution.The capacity is determined according to different requirements
• Strong anti-surge capability, able to withstand 2UnV surge voltage
• The ability to withstand high peak current, dv/dt up to 100V/μs, ESL inductance is small, and the charge and discharge speed is fast
The blue and white adjustable resistance potentiometer has a wide range of uses, and can be used in household appliances, electronic security and other industries. Specific products include: TV sets, induction cookers, rice cookers, etc.
