1. What is a through-hole resistor?
Through-hole resistor is a common name for plug-in resistors by some engineers, which means the resistor with a through hole in the middle.
The through hole in the middle is easy to install by inserting a metal rod. The through-hole resistor has a metal film or carbon film on the outer layer and a through hole in the middle of the color ring resistor. This through-hole resistor refers to the plug-in resistor. -
2. Through-hole resistor calculation method
The calculation method of through-hole resistor mainly depends on the basic calculation formula of resistor, that is, R=P*L/s, where R represents the resistance value, ρ is the resistivity, L is the length of the resistor, and S is the cross-sectional area of the resistor.
Through-hole resistors usually have a metal film or carbon film on the outside and a through hole in the middle. This structure allows for easy installation by inserting a metal rod. Through-hole resistors can be divided into precision and ordinary types. Precision plug-in resistors refer to resistors whose parameters meet certain requirements, such as a precision of 0.1%, a package of 1550, and a TCR (temperature coefficient) of 10PPM/℃. -
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.

4. What are the applications of through-hole resistors?
Voltage division: The required voltage is distributed through series resistors. It is often used for voltage sampling and current sampling. It is connected in series through precision resistors with small resistance. After voltage division, the voltage needs to be amplified by an amplifier.
Shunting: When the current in the loop is large and the power of one resistor is insufficient, the current is shunted through parallel resistors to play a protective role.
Current limiting: Limit the current passing through components to protect components, such as the current limiting resistor of LED light-emitting diodes.
Decoupling: In circuit operation, resistors are used to form a path to remove excess energy, which is used for inductive components.
Filtering: Together with capacitors, a filter circuit is formed. The cutoff frequency of the filter is calculated according to the resistance value and the capacitance value to achieve low-pass filtering or high-pass filtering.
Pull-up and pull-down: The pull-up resistor is connected to the positive end of the power supply, and the pull-down resistor is connected to the negative end of the power supply. It is used for signal output or input to prevent false operation caused by signal interference.
Dummy load: Connect a resistor in parallel with the output end of the power supply so that the output end does not form an empty load, which clamps the output voltage.
Jumper function: Mainly the use of 0 ohm resistors, used for debugging and compatibility, convenient wiring, reserved resistor positions, convenient current testing, noise suppression, safety protection and other occasions.
