Components Purchasing Services
We only purchase from the original factory or regular agent channels to ensure quality and quality.
Our prices are transparent. All commodity prices are reflected in the quotation—the sales price changes as the purchase price changes.
Many types, vast reserves
We have a lot of stock, eliminating the trouble of temporary purchases.
Various ways to meet customer needs
We provide pre-orders and purchasing services. If the spot stock is not enough, we offer an order service. If there is no stock of components required by customers, our company provides a purchasing function.
Our company supports retail. Solve prototype and small-batch procurement problem.
Quality is our only pursuit.
Basic Electronic Components Used in Circuits
This electronic component guide will try to explain in a very simple way how common electronic components work. This guide includes the following electronic components:
- Light Emitting Diode (LED)
- Integrated Circuit (IC)
- Electroacoustic Device
You’ll see resistors everywhere. And as the name suggests, they resist the current.
You use the resistor to control the voltages and the currents in your circuit.
You can think of a capacitor as a battery with very low capacity.
You can charge and discharge it just like a battery.
The capacitor is often used to introduce a time-delay in a circuit.
There are many capacitor types. Most commonly, we divide them into polarized and non-polarized capacitors.
Light Emitting Diode (LED)
A Light Emitting Diode – or LED for short – is a component that can give light.
We use LEDs to provide a visual feedback from our circuit.
For example to show that the circuit has power. But, you can also used them to make cool light-show circuits.
You see these components everywhere:
In your laptop, on your mobile phone, on your camera, in your car +++
And you can find many different types of LEDs.
This is probably the hardest of the basic electronic components to understand.
But don’t worry, it’s not that hard.
A simple way is to look at the transistor as a switch controlled by an electrical signal.
A transistor is similar to a relay because you can use it to turn on and off a current. The transistor is what makes amplifiers work.
Integrated Circuit (IC)
An Integrated Circuit (IC) consists of many basic electronic components.
It’s nothing mysterious or magical.
It’s just an electronic circuit that has been shrunk to fit inside a chip.
It could be an amplifier, it could be a microprocessor, it could be a USB to serial converter… It could be anything!
A relay is a switch that can be controlled electrically. If you connect power to the relay, the switch opens. If you disconnect the power, the switch closes. (Or vice versa).
Inductors are strange components made up of wire in a coil. They don’t like high frequencies.
It’s just a coil of wire – and you can make one yourself by making some loops out of a wire.
Sometimes they’re wound around a metal core of some sort.
They are often used to make radio oscillators, more efficient power supplies, and filters.
A crystal oscillator is a component used to create a precise frequency, such as a clock for a microcontroller.
- Temperature switch/temperature fuse
- Current fuse/fuse holder
- Self-recovery fuse/other insurance components
The sensor can feel the specified device or device measured and converted into usable signals according to a specific rule, usually composed of sensitive elements and conversion elements.
- Electromagnetic sensor/sensitive element
- Photoelectric sensor/optical fiber sensor
- Gas sensor/humidity sensor
- Displacement sensor/vision, image sensor
- Other sensors
Electroacoustic device: refers to a device that converts electricity and sound. It uses electromagnetic induction, electrostatic induction, or piezoelectric effect to complete the electroacoustic conversion, including
- speakers, headphones, microphones, and so on.
- Microphone/receiver/buzzer (Buzzer is an integrated electronic sounder with a DC voltage supply.)
CONNECTOR, also known as plugs and sockets. It generally refers to electrical connectors. That is a device that connects two active devices, transmitting current or signals.
- IC socket/optical fiber connector
- Binding post/cable connector
- Printed board connector/computer connector
- Mobile phone connector/terminal block/terminal block
- Other connectors
