470 Ohm 1/8W Through Hole Resistor (Pack of 5000)
The 470 Ohm 1/8W Through Hole Resistor is a precision carbon film resistor engineered for current limiting, voltage division, and signal conditioning applications in electronic circuits. Electronics engineers, hobbyists, and manufacturing professionals rely on these resistors for reliable current control in LED circuits, audio amplifiers, and digital logic interfaces. This bulk pack of 5000 units solves the challenge of maintaining consistent component inventory for high-volume prototyping, production runs, and educational electronics labs while ensuring cost-effective procurement.
Product Overview
The 470 Ohm 1/8W Through Hole Resistor operates on the principle of Ohm's Law, providing precise resistance to limit current flow and protect sensitive semiconductor components. With a rated power dissipation of 1/8 Watt (125mW), this resistor can safely handle continuous current up to approximately 16.3mA at full rated voltage, making it ideal for low-power signal processing circuits. The through-hole design features tinned copper leads that provide excellent solderability and mechanical stability on printed circuit boards, while the carbon film construction ensures tight tolerance ratings and minimal temperature coefficient drift across operating conditions.
This resistor excels in applications requiring reliable performance across industrial and consumer electronics. The 470 Ohm value sits in the sweet spot for LED current limiting in 5V logic circuits, audio signal attenuation, and pull-up/pull-down resistor networks. The bulk pack of 5000 units represents exceptional value for electronics manufacturers, educational institutions, and professional technicians who require consistent, high-quality components. Each resistor undergoes rigorous quality testing to ensure compliance with international standards, delivering predictable performance in mission-critical applications.

How to Use
Install the 470 Ohm 1/8W Through Hole Resistor by inserting its tinned copper leads through corresponding holes in your printed circuit board, ensuring proper alignment with the circuit schematic. Solder the leads using a temperature-controlled iron set between 350 to 380 degrees Celsius, applying solder for 2-3 seconds per joint to ensure reliable electrical connection and mechanical strength. Verify proper lead spacing matches your PCB hole pattern, typically 0.1 inch (2.54mm) for standard breadboards and prototype boards.
When designing circuits with this resistor, calculate the required resistance using Ohm's Law (R = V/I) to ensure the power dissipation does not exceed the 1/8 Watt rating. For LED current limiting applications, use the formula I = (Vsupply - Vled) / R to determine appropriate current flow. In high-temperature environments, apply derating factors to account for reduced power handling capacity above 70 degrees Celsius. Always measure actual resistance values with a digital multimeter before critical circuit assembly to verify component authenticity and tolerance compliance.
Frequently Asked Questions
What is the maximum current this 470 Ohm resistor can safely handle?
The maximum continuous current is determined by the power rating: I = sqrt(P/R) = sqrt(0.125/470) = approximately 16.3mA at full 1/8 Watt dissipation. However, for reliable long-term operation, limit current to 10-12mA to account for component aging and thermal margin. Always verify actual circuit conditions do not exceed this current rating.
Can I use these resistors in high-temperature industrial applications?
Yes, these resistors operate reliably from -55 to +155 degrees Celsius. However, power dissipation capability decreases at elevated temperatures. Apply a derating factor of approximately 0.5 at 125 degrees Celsius, meaning maximum safe power becomes 62.5mW. Verify your specific application requirements with thermal analysis to ensure component longevity.
What is the difference between 5% tolerance and 1% tolerance resistors?
The 5% tolerance on these resistors means the actual resistance value can vary within plus or minus 5% of the nominal 470 Ohm rating (447-493 Ohms). For applications requiring tighter matching such as precision analog circuits, 1% tolerance resistors are recommended. For most digital logic and LED applications, 5% tolerance provides adequate accuracy at lower cost.
Are these resistors suitable for surface mount PCBs?
No, these are through-hole resistors designed for insertion into drilled PCB holes. For surface mount applications, you require SMD resistors in 0603, 0805, or 1206 packages. Through-hole resistors offer superior mechanical strength for hand-soldered prototypes and breadboard circuits.
