Detailed info about Fusible Resistor. In this way, a fusible resistor serves dual functions. Without a resistor, we can’t imagine any circuit. Hello. Fusible Resistors Fusible resistors (Figure 7) can be carbon, carbon film, metal film, or wirewound. If the fusible resistor developed an open circuit or blown, you probably have shorted semiconductors that will need to be replaced US $0.01-$0.10 / Piece. There's a bunch of different codes - 2 spot, 2 band, 3 band, and 4 band - that vary quite a bit from manufacturer to manufacturer. There are 4, 5 and 6 band resistors. I'm a newbie that is stumped on a particular fusible resistor. A fusible resistor is designed to operate as a resistor during normal operating conditions, but to respond as a fuse in case of overloading. If there is no color band, the tolerance is 20 percent. A resistor is the most common passive two-terminal component used in the electronics circuit. 8.2 F ( ±1% ) & G ( ±2% ) ** Fusible type distinguish color code (WHITE) ** Does not indicate the color code of tolerance 5th band : distinguish color code (WHITE) 4th band : Multiplier 3rd band : digit 2nd band : digit 1st band : digit Color FUSIBLE RESISTORS Page : 11/22 Date : 2020.03.18 Confidential, Do Not Disseminate. Fusible resistors are a preferred passive component for many design engineers because they combine two roles: a fuse and a resistor. Most resistors have no band, a silver band or a gold band, but you may find resistors with other colors. commercial color bands.

Select the first 3 or 4 bands for 20%, 10% or 5% resistors and all 5 bands for precision (2% or less), 5-band resistors. They are usually flame retardant and are used in many consumer electronics such as I found a couple of fusible resistors on my old Harmon Kardon AVR30 receiver, blown. The generator voltage will be higher due to the generator’s internal impedance. to cust omer specifications. Use of Fusible Resistors. 14:00. You can get a good idea of power rating by the physical size of the resistor since power in a resistor always ends up as heat and must be dissipated. 5 Band Description. 2Ws 10RJ Flame proof wire-wound fusible resistor. 2. 1 Piece (Min Order) 12 YRS Changzhou Southern Electronic Element Factory Co., Ltd. 94.1%.

Fusible, Non-Flammable Metal Film Leaded Resistors DESCRIPTION A homogeneous film of metal alloy is deposited on a high grade ceramic body. Fusible, Resistors, Fixed manufactured by Vishay, a global leader for semiconductors and passive electronic components. There are three common types: 4 band, 5 band, and 6 band resistors. Resistor Color Code Calculator. Use this website to convert resistor color codes into resistor ohm value and tolerance. Marking The resistors are marked with a 3 colour band code indicating the value. FUSIBLE RESISTORS Page : 12/22 Date : 2020.01.01 Confidential, Do Not Disseminate. Read the color on the last color band, which is farthest right. The resistors have a 12 digit ordering code starting with 2306 or 2322. Features : Queen Mao resistor color coding system applies to Carbon Film, Metal Film, Metal Oxide Film, Fusible, and Wirewound of the axial lead type. Fusible Through-Hole Resistors Designed to protect circuit from abrupt transients and meet safety requirements Yageo offers complete range of fusible resistors which operate both as a normal resistor and as a fuse. Five Band Resistor Colour Code Resistors are available in several different versions of ‘Preferred Values’ as explained in Resistors & Circuits Module 2.2. A fuse resistor is an ordinary resistor (or a special fusible resistor, as Mike mentioned above) that is used as a fuse when its electrical characteristics are violated, resulting to its destruction --thus breaking the circuit. The Resistor Colour Code system is all well and good but we need to understand how to apply it in order to get the correct value of the resistor. 8.2 F ( ±1% ) & G ( ±2% ) ** Fusible type distinguish color code (WHITE) ** Does not indicate the color code of tolerance 5th band : distinguish color code (WHITE) 4th band : Multiplier 3rd band : digit 2nd band : digit 1st band : digit Color Introduction. The 5 band color codes are: Green, Blue, Brown, Red and White (pictured). This device used in various circuits. It is located in a negative supply line to 2 pins on a STK Integrated Circuit (Stereo Amplifier). FUSIBLE RESISTORS Page : 12/21 Date : 2018.01.26 Confidential, Do Not Disseminate. A Fusible Resistor is a wire-wound resistor that is designed to burn open easily when the power rating of the resistor is exceeded. Mr Carlson's Lab 447,014 views. The resistor is … If you encounter tjis type of resistor in the circuit do not replace it with normal reistor because this would cause fire danger is something goes wring in the circuit. Terminals may be supplied in any commercial material with several type finishes. Using one component versus two saves costs and PCB space. Resistor Color Code Calculator decodes value and tolerance of 4 and 5 band resistors. 5.0 (2) ... 47K 5% Resisrto Color Code Carbon Film Resistor 250 ohm 5w CF Fuse Resistors. The number of bands is important because the decoding changes based upon the number of color bands. A resistor is identified by its pattern of color of bands. There is a fifth white band in order to indicate the type of resistor. 8. 4. RESISTOR COLOR CODE––––––––––––....––––––.. 12 7. Contact Taiwan Other Resistors supplier-SUPERTECH ELECTRONIC CO., LTD. for Fusible Resistor, Resistor on Taiwantrade. 3. When fusible resistor overheats it cuts the current flowing like a fuse. intervals, ΔR < 5 %) NOTE: The voltage shown in these curves is the voltage across the resistor. Non-helixed resistors can be supplied for critical high frequency applications. 4- Band Code 5- Band Code RESISTOR COLOR CODE GUIDE 2 0 x10,000 10 % 20 x 10,000 = 200,000 1,000 = 1K Resistor = 200 K with a 10 % Tolerance+-First Band Second Band Multiplier Band Tolerance Band Equation The Gold or Silver band is always placed to the right. Fusible Resistors contain both functions, as being resistor in normal condition and changed into fuse while abnormal current comes in protect machines and equipment. The resistor … 1st, 2nd and 3rd color codes : nominal resistance value. After a helical groove has been cut in the resistive layer, tinned connecting wires of electrolytic copper are welded to the end-caps. The fifth band indicates the tolerance. Fuse Identification Mystery Marking Revealed. Fusible film resistors are ideal for applications with a lower power level and in which the overload- and surge-handling requirements are Only large resistors are marked with their rated power, usually 5 Watts and up.
