The 3 color band resistor color code red-brown-gray stands for 2.1 GΩ +/-20%, in words: two point one Gigaohms with plus/minus twenty percent tolerance.
This is a simple online calculator for color band resistor marking, inductor color band marking,
ceramic, film or tantalum capacitor 3 digit marking and SMD resistor 3-digit, 4-digit, 10%, 5%, 2% and EIA-96 (E96) 1% tolerance code marking.
