When the power isn't exceeded, it serves as a resistor limiting current. A resistor is the most common passive two-terminal component used in the electronics circuit. FUSIBLE RESISTORS Page : 12/22 Date : 2020.01.01 Confidential, Do Not Disseminate. Mr Carlson's Lab 447,014 views. Terminals may be supplied in any commercial material with several type finishes. Resistor color codes 4 color bars. The fourth band indicates the multiplier. There is a fifth white band in order to indicate the type of resistor. Fusible resistors are a preferred passive component for many design engineers because they combine two roles: a fuse and a resistor. Fuse Identification Mystery Marking Revealed. 4. fuse resistors with Rohs Product Detail Product RXF wirewound fusible resistor Color Grey Coating Power 1/2W 1WS 1W Resistance 0.1-160 Certificate UL ISO9001 ISO14001 ISO/TS16949 CQC ROHS Parameter and Dimension Auto Working Machines PATENTS MAIN CUSTOMERS FAIR SHOW Packing Ms. Coco Wen Phone:8613915084415 QQ: 602055462 skype:aegean008 Whatsapp/Wechat: … The resistor is … Read the color on the last color band, which is farthest right. When fusible resistor overheats it cuts the current flowing like a fuse. A fusible resistor is designed to operate as a resistor during normal operating conditions, but to respond as a fuse in case of overloading. Color banded axial lead resistors with 4 or 5 bands are supported. 5.0 (2) ... 47K 5% Resisrto Color Code Carbon Film Resistor 250 ohm 5w CF Fuse Resistors. to cust omer specifications. 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 I'm a newbie that is stumped on a particular fusible resistor. Detailed info about Fusible Resistor. 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. I'm having a hard time sourcing this … They are usually flame retardant and are used in many consumer electronics such as E.3 Markings: Markings are to be shown on the resistor body by color coding. Hi Joel, Your color decoding is correct. The resistors have a 12 digit ordering code starting with 2306 or 2322. Using one component versus two saves costs and PCB space. 2Ws 10RJ Flame proof wire-wound fusible resistor. It is located in a negative supply line to 2 pins on a STK Integrated Circuit (Stereo Amplifier). Without a resistor, we can’t imagine any circuit. If there is no color band, the tolerance is 20 percent. E.2 Coating: Coating is overcoat the resistor body with light grey non-flammable paint. Fusible film resistors are ideal for applications with a lower power level and in which the overload- and surge-handling requirements are After a helical groove has been cut in the resistive layer, tinned connecting wires of electrolytic copper are welded to the end-caps. To calculate the resistance of a resistor, you can select the appropriate color bands in the above resistor color code … Resistor Color Code Calculator. 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. This system is employed for resistors when the surface area is not sufficient to print the resistance value for the past time. The tolerance color code is as follows: 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. Most resistors have no band, a silver band or a gold band, but you may find resistors with other colors. All About Resistor How To Read Code Of SMD Resistor Colour Code Of Resistor. FUSIBLE RESISTORS Page : 12/21 Date : 2018.01.26 Confidential, Do Not Disseminate. 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. Resistor color code calculator The calculator above will display the value , the tolerance and performs a simple check to verify if the calculated resistance matches one of the EIA standard values. intervals, ΔR < 5 %) NOTE: The voltage shown in these curves is the voltage across the resistor. COLOR CODING 8.1 Color code ** Fusible type distinguish color code (WHITE) 5th band : distinguish color code (WHITE) 4th band : Tolerance 3rd band : Multiplier 2nd band : digit 1st band : digit Color 1st, 2nd (Significant Figure) 3rd (Multiplier) 4th US $0.0012-$0.0015 / Piece. The number of bands is important because the decoding changes based upon the number of color bands. Since two functions performed by one resistor, ... color code Figure7 FUSIBLE RESISTORS Winsonic Page 11 of 11. Fusible Resistors contain both functions, as being resistor in normal condition and changed into fuse while abnormal current comes in protect machines and equipment. 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. Marking The resistors are marked with a 3 colour band code indicating the value. Introduction. 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 I found a couple of fusible resistors on my old Harmon Kardon AVR30 receiver, blown. Reading Resistor Color Codes Fast, Tech Tips Tuesday - Duration: 14:00. The “left-hand” or the most significant coloured band is the band which is nearest to a connecting lead with the colour coded bands being read from left-to-right as follows: commercial color bands. 2. The resistors are suitable for processing on automatic insertion equipment. Some of these versions contain a wider range of values, requiring a more accurate numerical value and closer tolerance ratings than can be achieved in the four band colour code. A Fusible Resistor is a wire-wound resistor that is designed to burn open easily when the power rating of the resistor is exceeded. 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. Resistors come in many shapes and sizes this tool is used to decode information for color banded axial lead resistors. Only large resistors are marked with their rated power, usually 5 Watts and up. If the fusible resistor developed an open circuit or blown, you probably have shorted semiconductors that will need to be replaced 1st, 2nd and 3rd color codes : nominal resistance value. 5 Band Description.
