With the continuous improvement of living standards, people's demand for large and small household appliances is constantly increasing, and the requirements for various aspects of household appliances are also getting higher. As a result, small household appliance control boards are gradually growing with the development of the domestic household appliance industry. Trust us, we also know that the small household appliance control board can remotely control household appliances by phone, enabling them to connect, disconnect, and issue infrared switch commands, and then achieve home intelligence. So what are the primary components on the small home appliance control board?

1. Resistance: Resistance is a resistor, which is a current limiting element. After connecting a resistor to a circuit, the resistance value of the resistor is fixed, usually consisting of two pins, which can constrain the magnitude of the current passing through the branch it is connected to; It can also be said that it is an energy consuming component, and the current passing through it generates internal energy. Resistors generally have the effect of dividing voltage and current in circuits.

2. Capacitor: Capacitor, also known as "capacitance", is a physical quantity that represents the capacity of a capacitor to contain charges. Physically speaking, it is a static charge storage medium that may contain charges. It is an indispensable electronic component in small home appliance control boards.

3. IC: Integrated circuit is a type of miniature electronic device or component that uses a certain process to interconnect the required transistors, resistors, capacitors, inductors, and other components and wiring in a circuit. It is manufactured on a small or several small semiconductor chips or dielectric substrates, and then packaged in a tube shell to become a microstructure with the required circuit functions. Generally, the letter IC is used to represent the circuit.

4. Transformer: A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The primary components are the primary coil, secondary coil, and iron core (magnetic core). Its primary functions include voltage switching, current switching, impedance switching, barrier switching, and voltage stabilization (magnetic saturation transformer)

5. Buzzer: A buzzer is an electronic sounder with a structure that uses DC voltage for power supply. It is mainly divided into two types: piezoelectric buzzer and electromagnetic buzzer. The buzzer is represented by the letters "H" or "HA" at the top of the circuit (old standards used "FM", "ZZG", "LB", "JD", etc.).

The above are the primary components used on small home appliance control boards. With the development of information technology, the 4-bit and 8-bit MCUs used on small home appliance control boards can no longer be the backbone of the future. More and more microcontrollers and CPUs are gradually approaching PCs for data accounting.
