1. Resistor parameters
Through-hole resistor 10k/0.25w parameters
The parameters of the through-hole resistor 10k/0.25w include nominal resistance 10KΩ, rated power 0.25W, accuracy 1%, and installation type is through-hole.
Nominal resistance: 10KΩ, indicating that the basic resistance of the resistor is 10,000 ohms.
Rated power: 0.25W, meaning that the maximum power the resistor can withstand continuously is 0.25 watts.
Accuracy: 1%, indicating that the deviation between the actual resistance of the resistor and the nominal resistance does not exceed 1%.
Mounting type: through-hole, indicating that this resistor is suitable for through-hole installation, usually for through-hole installation on circuit boards. -
2. How to identify color ring resistors
1. Four-color ring resistors
Four-color ring resistors refer to resistors that use four color rings to indicate resistance, counting from left to right, as shown in the figure. The first color ring indicates the largest digit of the resistance; the second color ring indicates the second digit of the resistance; the third color ring indicates the number of times the resistance is multiplied; the fourth color ring indicates the allowable deviation (accuracy) of the resistance.
For example, if the first ring of a resistor is red (representing 2), the second ring is purple (representing 7), the third ring is brown (representing 10 times), and the fourth ring is gold (representing ±5%), then the resistance of this resistor should be 270Ω, and the error range of the resistance is ±5%.
2. Five-color ring resistor
Five-color ring resistor refers to a resistor that uses five color rings to represent the resistance, counting from left to right, as shown in the figure. The first color ring represents the largest digit of the resistance; the second color ring represents the second digit of the resistance; the third color ring represents the third digit of the resistance; the fourth color ring represents the multiplier of the resistance; the fifth color ring represents the error range.
For example, if a five-color ring resistor, the first ring is red (representing 2), the second ring is red (representing 2), the third ring is black (representing 0), the fourth ring is black (representing 1 times), and the fifth ring is brown (representing ±1%), then its resistance is 220Ω×1=220Ω, and the error range is ±1%.
3. Six-color ring resistors
Six-color ring resistors refer to resistors that use six color rings to represent resistance values. As shown in Figure 1, the first five color rings of the six-color ring resistor are the same as the five-color ring resistor, and the sixth color ring represents the temperature coefficient of the resistor. -
3. 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. -
4. 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.
