4.7K Ohm 1/8W Through Hole Resistor (Pack of 5000)
The 4.7K Ohm 1/8W Through Hole Resistor is a precision carbon film resistor designed for general-purpose circuit applications requiring stable resistance values and low noise characteristics. Professional electronics engineers, hobbyists, and PCB manufacturers rely on this component for voltage divider networks, pull-up/pull-down circuits, and signal conditioning in microcontroller-based projects. This bulk pack of 5000 units solves the challenge of maintaining consistent component inventory for high-volume prototyping, educational laboratories, and manufacturing operations while eliminating frequent reordering cycles.
Product Overview
The 4.7K Ohm 1/8W Through Hole Resistor operates on the principle of electrical resistance, where a carbon film element provides a precise 4700-ohm impedance across a wide frequency range. The 1/8 watt power rating indicates the maximum continuous power dissipation capacity, making this resistor ideal for low-power signal circuits where current flow typically remains below 5mA at standard operating voltages. The through-hole configuration features tinned copper leads that insert directly into breadboards or PCB holes, ensuring reliable mechanical connections and excellent solderability for both hand assembly and automated wave soldering processes.
This resistor excels in applications requiring tight tolerance specifications and minimal temperature drift. The carbon film construction delivers superior frequency response compared to carbon composition alternatives, with negligible inductance suitable for audio and RF applications up to several megahertz. The bulk pack of 5000 units provides exceptional value for electronics laboratories, educational institutions, and manufacturing facilities that require consistent component availability without premium pricing associated with smaller quantity purchases.

How to Use
To implement the 4.7K Ohm 1/8W Through Hole Resistor in your circuit, first identify the circuit locations requiring this resistance value based on your schematic design. Insert the tinned copper leads through the appropriate PCB holes or breadboard sockets, ensuring proper component orientation if the circuit design specifies directional requirements. For PCB assembly, solder both leads using a temperature-controlled iron set to 350-380 degrees Celsius for 3-5 seconds per joint, maintaining adequate solder flow without excessive heat exposure that could damage the carbon film element.
When designing circuits using this resistor, calculate the maximum current flow using Ohm's Law to ensure the 1/8 watt power rating is not exceeded. For a 4.7K Ohm resistor, the maximum safe current at full power rating is approximately 5.2mA. In pull-up applications on microcontroller pins, this value provides excellent noise immunity while maintaining fast signal transition times suitable for I2C and standard logic circuits. Always verify component placement against your circuit schematic before soldering, and perform continuity testing after assembly to confirm proper installation and solder joint integrity.
Frequently Asked Questions
What is the maximum current that can safely flow through a 4.7K Ohm 1/8W resistor?
Using the power formula P equals I squared times R, the maximum safe current is approximately 5.2 milliamps at full 1/8 watt dissipation. However, for reliable long-term operation in practical circuits, limit continuous current to 3-4 milliamps to maintain component temperature within safe margins and extend service life beyond minimum specifications.
Can I use 4.7K Ohm resistors for I2C pull-up applications?
Yes, 4.7K Ohm is the standard recommended pull-up resistance for I2C bus implementations at 5V and 3.3V logic levels. This value provides optimal balance between noise immunity and signal transition speed, ensuring reliable communication across typical I2C bus lengths up to several meters without signal degradation.
What is the temperature coefficient and how does it affect circuit performance?
The temperature coefficient of 100 PPM per degree Celsius means the resistance value changes by 0.01 percent for each degree Celsius temperature change. In most signal-level applications, this variation is negligible, but in precision analog circuits requiring high accuracy, temperature compensation or selection of resistors with lower temperature coefficients may be necessary.
Are these resistors suitable for high-frequency RF applications?
Carbon film resistors perform well up to several megahertz with minimal parasitic inductance. However, for RF applications above 100 MHz, metal film or thick film resistors with lower frequency-dependent impedance variations are recommended to prevent impedance shifts that could affect circuit tuning and performance.
