Chaque couleur correspond à un chiffre (voir tableau ci-dessous, à droite). The time to fuse depends on the resistance value. Dimensions are in millimetres unless otherwise specified. I've also noticed that most (if not all) fusible resistors have a matt finish and not a gloss finish. Once you place the probes against the resistor’s leads, you should receive a value for the resistor. The fixed resistors are classified into different types, depending upon their manufacturing processes and the materials used in their manufacturing.
