A 10R ohm resistor has a resistance value of 10 ohms, where the letter "R" acts as a decimal point.

Key Specifications

Resistance Value: 10 Ω (10 ohms)
Meaning of "10R": The letter "R" replaces the decimal point or indicates ohms in standard component shorthand (e.g., 4R7 would be 4.7 ohms, and 10R is 10.0 ohms).
Color Code (4-band or 5-band through-hole):
• Brown (1)
• Black (0)
• Black (0 multiplier or 3rd digit)
• Gold (multiplier of 0.1) or Black multiplier depending on band count.
Common Power Ratings: 1/4W (axial/through-hole), 1/8W (SMD), or higher power wirewound variants like the AH50W-10R-J Aluminum Resistor.
