A power management IC is a special-purpose integrated circuit whose function is to manage power for the main system. PMICs are commonly used in battery powered devices such as mobile phones or portable media players.

The integrated circuit adopts a semiconductor manufacturing process to manufacture multiple transistors, resistors, capacitors and other components on a small single-crystal silicon wafer, and combine the components into a complete electronic circuit in the form of multi-layer wiring or tunnel wiring. .

The isolator adopts the principle of linear optocoupler isolation to realize the conversion and output of the input signal. Input, output and working power are isolated from each other, especially suitable for use with instruments that require electrical isolation.

A signal is the form or carrier in which information exists. In automatic instrumentation equipment and automatic control systems, one kind of signal is often converted into another kind of signal which is compared with the standard quantity or reference quantity, so as to connect the two types of instruments, so the converter is often two instruments (or device) intermediate link.

An interface chip is a chip with an internal interface circuit. Conversion of information formats, such as serial and parallel conversion, etc.

A clock chip is a chip with clock characteristics that can real-time time. The clock chip is a kind of integrated circuit, which mainly consists of a rechargeable lithium battery, a charging circuit and a crystal oscillator circuit.

A storage module refers to a collection of products that can perform storage tasks, including solid-state drives, USB flash drives, and storage devices such as memory cards and storage devices.

Sensor is a detection and automatic control device that can sensitively analyze external changes or object behavior, and can output information according to certain rules, and is a key component to realize detection and control automation.

Integrated circuits are divided into three categories: analog integrated circuits, digital integrated circuits and hybrid integrated circuits. Among them, digital integrated circuits are mainly composed of various gate circuits, combinational circuits, flip-flops, counters, etc., which complete certain logical functions, also known as logic. circuit or logic integrated circuit.

An audio amplifier is a device that reconstructs an input audio signal with an output element that produces sound at an ideal volume and power level—true, efficient, and with little distortion.

The LED driver refers to the power adjustment electronic device that drives the LED to emit light or the LED module assembly to work normally.

Diode is one of the earliest semiconductor devices, and its application is very wide. A diode is an electronic device made of semiconductor materials (silicon, selenium, germanium, etc.). It has unidirectional conductivity.

A transistor is a solid-state semiconductor device (including diodes, triodes, field effect transistors, thyristors, etc., sometimes referred to as bipolar devices), with functions such as detection, rectification, amplification, switching, voltage regulation, and signal modulation.

Photoelectric devices refer to devices made according to the photoelectric effect, called optoelectronic devices, also known as photosensitive devices. There are many types of optoelectronic devices, but their working principles are all based on the physical basis of the photoelectric effect.

The crystal oscillator is the most common type of electronic component in the circuit. Its main working principle is to pressurize the metal sheet of the order of magnitude after the crystal is pressurized and deformed. The interaction of these two voltages causes the crystal to resonate.

Audio is a technical term that is used as a general term to describe sound-related audio ranges and devices and their capabilities.

Discrete semiconductors are part of semiconductors. Discrete semiconductors are electronic components composed of a single semiconductor, such as transistors or diodes, triodes, and so on.

Capacitors are the most common type of electronic components in general circuits. The structure of capacitors is relatively simple. A capacitor is formed by placing two conductors close to each other on both sides of an insulating medium.

As a current limiting element, the resistor can limit the current size of the circuit it is connected to after being connected to the circuit.

A connector is a discrete element, usually installed on equipment such as cables, to electrically connect different transmission line systems (excluding converters).

Switch components refer to a class of electronic components that control the opening or closing of circuits in a circuit so that current is turned off or on or flows to other circuits.

Circuit protection components are mainly used to protect the components in the circuit from damage caused by overvoltage and overcurrent in certain environments.

A cable is a transmission device consisting of one or more wires or groups of wires insulated from each other to transmit power or electrical signals.

Radio frequency refers to the electromagnetic frequency that can be radiated into space, and the frequency range is between 300kHz and 300GHz. Radio frequency is radio frequency current, referred to as RF, which is the abbreviation of high frequency alternating electromagnetic wave. RF is the abbreviation of AC frequency conversion high frequency electromagnetic wave.

A filter is a filter circuit composed of capacitors, inductors and resistors. The filter can effectively filter the frequency point of a specific frequency in the power line or the frequency other than the frequency point to obtain a power signal of a specific frequency, or eliminate the power signal of a specific frequency.

A relay is a control device commonly used in our lives. In a popular sense, it is a switch, which is turned off or turned on when the conditions are met.

Transformers generally refer to devices that change voltage in circuits. The principle is to use electromagnetic induction to change voltage. It is composed of primary coils, secondary coils and magnetic cores. Transformers can be divided into power transformers and special transformers according to their application types. type.

Industrial supplies are the instruments, tools or materials needed for industrial production or construction. Industrial supplies include CNC equipment, insulating materials, mechanical design and processing. Instruments, meters, lighting and lamps, etc.

Mechanical and electrical equipment generally refers to machinery, electrical appliances and electrical automation equipment. It is different from hardware, which refers to finished products that can achieve certain functions.

There are many types of component kits, such as hardware kits, sensor kits, optical fiber kits, etc., and their application scenarios are also very rich.

The means of testing is instrumentation. Because test and measurement are closely related, in practice, there is often no strict distinction between test and measurement.
