Resistor

Description:

A resistor of PCB refers to a resistor that is mounted on a Printed Circuit Board (PCB). A resistor is an electronic component that is designed to resist the flow of electric current in a circuit. It is typically used to reduce the voltage in a circuit or to limit the current flowing through a circuit.

​

In the context of PCBs, resistors are used to create specific values of resistance in electronic circuits. They are typically small, cylindrical components with two metal leads that can be inserted through holes in the PCB and soldered in place. PCB-mounted resistors are available in various sizes, shapes, and resistance values to meet the needs of different electronic circuits.

​

The value of a resistor is determined by its color-coded bands, which represent the resistance value, tolerance, and temperature coefficient. PCB-mounted resistors are commonly used in electronic devices, such as computers, televisions, and other consumer electronics, as well as in industrial applications.

Advantages:

  • Precise Resistance Value: Resistors are designed to provide a specific value of resistance, which is essential for the proper functioning of electronic circuits. This allows for precise control of current flow and voltage levels in the circuit.

  • Size and Space: Resistors come in various sizes and shapes, allowing them to be integrated into a PCB in a compact and space-saving manner. This is particularly important for small electronic devices where space is limited.

  • Cost-Effective: Resistors are relatively inexpensive electronic components, which makes them cost-effective for use in large-scale production of electronic devices.

  • Temperature Stability: Resistors are designed to maintain their resistance value even when exposed to temperature changes, ensuring the stability of the electronic circuit.

  • Durability: PCB-mounted resistors are designed to withstand mechanical and thermal stresses, making them durable and reliable components for electronic circuits.

  • Ease of Installation: PCB-mounted resistors are easy to install on a PCB, requiring only two leads to be soldered onto the board, which makes them a convenient component for use in electronic devices.

Procurement Process:

  1. Define Requirements: The first step is to define the requirements for the resistors based on the specifications of the PCB design. This includes the resistance value, tolerance, power rating, package size, and other relevant factors.

  2. Quotation: We will send a quotation sheet to customers. The quotation should include the specifications for the resistors, the required quantity, and any other relevant information, such as delivery requirements and payment terms.

  3. Quality Control: Before the resistors are used in the PCB assembly, they should be inspected for quality and consistency, ensuring that they meet the required specifications and are compatible with other components in the circuit.

  4. Delivery.
