Calculation Formulas

// Absolute Value
Resistance =
(D1 × 100 + D2 × 10 + D3)
× Multiplier
// Operating Tolerances
Min = R × (1 − Tolerance)
Max = R × (1 + Tolerance)

* Note: In a 5-band configuration, the tolerance band is typically wider or separated by an extra space at the right end of the resistor body.

Frequently Asked Questions

A 5-band resistor is an electrical passive component that relies on five colored bands printed around its body to define its resistance value, multiplier, and precision tolerance. The addition of a third digit band allows for significantly higher resolution and precision than typical 4-band resistors.

Read bands from left to right. Locate the band situated closest to one side of the terminal - this is Band 1. In a 5-band resistor, the first three bands denote the numerical values of the digits, the fourth is the multiplier (power of 10), and the fifth represents the operational tolerance percentage.

High-accuracy applications require tight components tolerances (typically 1%, 0.5% or lower) and highly specific resistance parameters (e.g. 249 Ω). Having three digit bands enables engineers to specify complex decimal-aligned numbers with extreme accuracy.

Tolerance corresponds to the maximum deviation allowed from the nominal resistance rating. For instance, a 10 kΩ resistor with a ±1% tolerance means the component’s true physical resistance can safely vary between 9.90 kΩ and 10.10 kΩ.

The principal differentiator is the count of significant digit bands. A 4-band resistor uses only the first two bands as digits followed by the multiplier and tolerance. A 5-band resistor adds a third digit band, providing highly precise target definitions.

Generally, the tolerance band (5th band) is visibly spaced slightly further away from the other four bands. Furthermore, the first digit band is frequently closer to its respective terminal cap edge compared to the other end.
