Application of RWR78S38R3FRB12

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.

RWR78S38R3FRB12 Classification

Through Hole Resistors

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.

FAQ about Through Hole Resistors

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

    The DIP package is a double-row in-line package with two rows of pins arranged in parallel. DIP packages are widely used in integrated circuits, resistors, capacitors and other components, such as operational amplifiers, microcontrollers, etc.
    The SIP package is a single-row in-line package with one row of pins. SIP packages are commonly used in resistor arrays, capacitor arrays and power modules.

  • 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. 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.
