Made in China. Review: All measured within 5% as advertised - I tested the values on my HP bench top multimeter using 4-wire Kelvin clips. I ordered these to replace some 500 Ω 10% resistors in my 70s vintage stereo amplifier. These 5% tolerance resistors were all within 5% and three of the 20 measured exactly 500 Ω. Most measured within 2.5%. The worst one measured 493 Ω. Review: Prompt shipping - Work as they should and arrived on time ## Features - Composition: Metal Oxide - Resistance (ohm): 500 - Tolerance (%): 5 - Power (Watts): 5 - Voltage Rating: 1000 V ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.5 out of 5 stars 52 Reviews | ## Images ![Jameco Valuepro RSF/MO5WS500RJBU Resistor Metal Oxide 500 Ohm 5W 5% (Pack of 20) - Image 1](https://m.media-amazon.com/images/I/51RuTSDNEdL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ All measured within 5% as advertised *by K***N on June 4, 2026* I tested the values on my HP bench top multimeter using 4-wire Kelvin clips.
