47K Ohm 1/8W Through Hole Resistor (Pack of 5000)
The 47K Ohm 1/8W Through Hole Resistor is a precision carbon film resistor designed for current limiting, voltage division, and signal conditioning in electronic circuits. Electronics engineers, hobbyists, and PCB assembly professionals rely on these resistors for prototyping, production runs, and maintenance applications where reliability and accuracy are critical. This bulk pack of 5000 units solves inventory management challenges for manufacturers and educational institutions by providing cost-effective component sourcing with consistent tolerance specifications.
Product Overview
Through hole resistors operate on the fundamental principle of ohmic resistance, where electrical current flowing through the component experiences opposition proportional to its resistance value. The 47K Ohm rating means this resistor provides 47,000 ohms of resistance, making it ideal for mid-range impedance applications. The 1/8W power rating indicates the resistor can safely dissipate 0.125 watts of power without exceeding its thermal limits. Carbon film construction provides excellent frequency stability, low noise characteristics, and superior performance in temperature-sensitive applications compared to carbon composition alternatives. The through hole design allows for easy hand soldering, breadboard prototyping, and automated wave soldering processes in manufacturing environments.
This resistor pack of 5000 units represents exceptional value for electronics manufacturers, educational laboratories, and repair service centers that require consistent component availability. Each resistor is manufactured to industry standard tolerances, ensuring predictable circuit behavior across multiple production batches. The bulk quantity eliminates frequent reordering cycles and reduces per-unit costs significantly compared to smaller packaging options. Carbon film technology ensures stable resistance values across temperature ranges from -55°C to +125°C, maintaining circuit accuracy in diverse environmental conditions.

How to Use
When integrating 47K Ohm resistors into your circuit design, calculate the required current and power dissipation using Ohm's Law (I = V/R) and the power formula (P = I²R or P = V²/R). For a 5V circuit with a 47K resistor, the current will be approximately 106 microamps with power dissipation around 0.56 milliwatts, well within the 1/8W rating. Insert the resistor leads through the PCB holes with proper orientation (resistors are non-polarized) and solder using a temperature-controlled iron set between 350°C to 380°C for 3-5 seconds per joint to avoid thermal damage.
For breadboard prototyping, simply insert the leads into adjacent holes and verify continuity using a multimeter before powering the circuit. In automated wave soldering processes, ensure proper lead spacing and PCB design to prevent bridging between adjacent components. Store unused resistors in dry conditions between 15°C to 25°C to maintain tolerance specifications. For high-reliability applications, consider derating the component to 50% of its maximum power rating to extend operational life and improve circuit stability.
Frequently Asked Questions
What is the difference between 47K Ohm 1/8W and 1/4W resistors?
The primary difference is power dissipation capacity. A 1/8W resistor safely handles 0.125 watts while a 1/4W resistor handles 0.25 watts. For low-power circuits like audio preamps, microcontroller interfaces, and sensor circuits, 1/8W is sufficient. Use 1/4W resistors in high-current applications or when operating near maximum voltage ratings to provide safety margin and extended component life.
Can I use a 47K Ohm resistor in place of other resistance values?
No, resistor values are not interchangeable as they directly affect circuit behavior. A 47K Ohm resistor provides 47,000 ohms of resistance. Using a different value will change current flow, voltage division ratios, time constants in RC circuits, and amplifier gain characteristics. Always use the exact resistance value specified in your circuit schematic to ensure proper operation.
What does 5% tolerance mean for these resistors?
5% tolerance means the actual resistance value will be within 5% of the marked 47K Ohm value, ranging from 44.65K Ohm to 49.35K Ohm. This tolerance is suitable for most general-purpose applications. For precision circuits requiring tighter tolerances, consider 1% metal film resistors, though at higher cost per unit.
Are these resistors suitable for high-frequency applications?
Carbon film resistors perform well up to several megahertz with low parasitic inductance. For RF applications above 100 MHz, consider metal film or wirewound resistors with lower frequency-dependent characteristics. The 47K value is commonly used in audio circuits up to 20 kHz and general signal conditioning applications without frequency-related issues.
