Through Hole Resistors is a classic electronic component, has been called plug-in resistance. It refers to those resistors that are soldered and fixed by metal pins through holes in the circuit board and are mainly used to limit current, regulate voltage and divide voltage circuits. Through hole resistance can be divided into precision type and ordinary type, precision through hole resistance has higher parameter requirements. Compared with surface mount resistors, through-hole resistors show different characteristics and advantages in assembly and maintenance.

Through Hole Resistors is a plug-in resistor with a through hole structure. Due to its high reliability, good heat dissipation performance, and easy maintenance, it is widely used in industrial control, communication equipment, automotive electronics, consumer electronics and other fields. Especially in the need to withstand higher power or harsh working environment, the advantages of through-hole resistance are more obvious. They are capable of long-term stable operation and maintain good performance even under extreme conditions such as high temperature, high humidity or vibration. The pin design of the through-hole resistor allows it to be easily fixed to the circuit board by welding, which is especially important for some circuit projects that require manual assembly or debugging. This flexible assembly method not only improves production efficiency, but also reduces maintenance costs.

• 1. What are the advantages of through-hole resistors?

  Strong component connection‌: Through-hole technology passes through the circuit board through physical leads and is soldered on the other side, forming a strong connection that can resist mechanical stress. This makes through-hole resistors an excellent choice for components that are subject to physical strain, such as connectors, switches, or large, heavy components.
  ‌Reliable performance at high temperatures‌: Through-hole components are generally more resistant to extreme thermal environments, which is beneficial for applications that operate in high-temperature environments or undergo significant thermal cycles.
  ‌Easy to prototype and debug‌: Through-hole components are generally easier to use for manual assembly, prototyping, or testing. They can be manually inserted and soldered, making it easy to debug or modify prototypes.
  ‌Enhanced testability‌: Circuit boards designed with through-hole designs inherently provide excellent testability. The lead ends of the devices in the through-hole board also act as test nodes, which enables efficient online testing because the test probes can easily access them from the bottom. This makes it easier and more efficient to diagnose and fix any potential problems.

• 2. What are the classifications of through-hole resistors?

  1. Unidirectional through-hole resistors
  
  Unidirectional through-hole resistors are one of the simplest through-hole resistors. It has only one through-hole aperture, and current can only enter and flow through the resistor body in one direction. Unidirectional through-hole resistors are characterized by simple structure and low manufacturing cost.
  
  2. Bidirectional through-hole resistors
  
  Bidirectional through-hole resistors have the characteristics of bidirectional current flow and can be used as voltage dividers, RC couplers, inductive couplers, etc. It has a bidirectional cutting process and requires higher precision and technical requirements during the manufacturing process.
  
  3. Multi-circular hole resistors
  
  Multi-circular hole resistors are a type of multi-hole through-hole resistor with higher power carrying capacity and lower inductance value. It is suitable for use in high frequency and high temperature environments, such as power supplies and switching circuits.
  
  4. Multi-rectangular through-hole resistors
  
  Multi-rectangular through-hole resistors have multiple rectangular through-hole apertures and can be used in the manufacture of high-power devices. It has stronger resistance to mechanical stress and better heat dissipation performance, and can be used in power tools, aerospace and other fields.

• 3. Definition and function of through-hole resistors

  A through-hole resistor is a resistor device that can fix the resistor body and wire by perforating holes to achieve the purpose of fixing and conducting current. Through-hole resistors are widely used in various circuits, such as power amplifiers, digital circuits, analog signal processors, etc.
