This device used in various circuits. 2Ws 10RJ Flame proof wire-wound fusible resistor. 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. to cust omer specifications. 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: … There are three common types: 4 band, 5 band, and 6 band resistors. Terminals may be supplied in any commercial material with several type finishes. Introduction. The resistors are suitable for processing on automatic insertion equipment. E.2 Coating: Coating is overcoat the resistor body with light grey non-flammable paint. Without a resistor, we can’t imagine any circuit. If the fusible resistor developed an open circuit or blown, you probably have shorted semiconductors that will need to be replaced The number of bands is important because the decoding changes based upon the number of color bands. Resistor color codes 4 color bars. There are 4, 5 and 6 band resistors. 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. Fusible, Resistors, Fixed manufactured by Vishay, a global leader for semiconductors and passive electronic components. In this way, a fusible resistor serves dual functions. 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. The generator voltage will be higher due to the generator’s internal impedance. Contact Taiwan Other Resistors supplier-SUPERTECH ELECTRONIC CO., LTD. for Fusible Resistor, Resistor on Taiwantrade. Special pre-conditioning (power aging, temperature cycling, etc.) 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. 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: The fifth band indicates the tolerance. 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 2. 1st, 2nd and 3rd color codes : nominal resistance value. Five Band Resistor Colour Code Resistors are available in several different versions of ‘Preferred Values’ as explained in Resistors & Circuits Module 2.2. 5 Band Description. When the power isn't exceeded, it serves as a resistor limiting current. A fusible resistor is designed to operate as a resistor during normal operating conditions, but to respond as a fuse in case of overloading. Read the color on the last color band, which is farthest right. 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. 5.0 (2) ... 47K 5% Resisrto Color Code Carbon Film Resistor 250 ohm 5w CF Fuse Resistors. Use of Fusible Resistors. Most resistors have no band, a silver band or a gold band, but you may find resistors with other colors. To calculate the resistance of a resistor, you can select the appropriate color bands in the above resistor color code … 8. The tolerance color code is as follows: Fusible resistors are a preferred passive component for many design engineers because they combine two roles: a fuse and a resistor. When fusible resistor overheats it cuts the current flowing like a fuse. FUSIBLE RESISTORS Page : 12/21 Date : 2018.01.26 Confidential, Do Not Disseminate. Hi Joel, Your color decoding is correct. They are usually flame retardant and are used in many consumer electronics such as Resistor body colors white and blue are used to mark non-flammable resistors and fusible resistors. It is located in a negative supply line to 2 pins on a STK Integrated Circuit (Stereo Amplifier). Fusible Resistors contain both functions, as being resistor in normal condition and changed into fuse while abnormal current comes in protect machines and equipment. E.3 Markings: Markings are to be shown on the resistor body by color coding. Mr Carlson's Lab 447,014 views. Fuse Identification Mystery Marking Revealed. A resistor is the most common passive two-terminal component used in the electronics circuit. 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. Use this website to convert resistor color codes into resistor ohm value and tolerance. The fourth band indicates the multiplier. Since two functions performed by one resistor, ... color code Figure7 FUSIBLE RESISTORS Winsonic Page 11 of 11. Fusible, Non-Flammable Metal Film Leaded Resistors DESCRIPTION A homogeneous film of metal alloy is deposited on a high grade ceramic body.

Color banded axial lead resistors with 4 or 5 bands are supported. 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. Reading Resistor Color Codes Fast, Tech Tips Tuesday - Duration: 14:00. commercial color bands. This represents the tolerance of the resistor. If there is no color band, the tolerance is 20 percent. The resistor is … Packaging FRN25, FRN50S and FRN100S are normally supplied taped in 'ammo' boxes of 4,000 pieces. Features : Queen Mao resistor color coding system applies to Carbon Film, Metal Film, Metal Oxide Film, Fusible, and Wirewound of the axial lead type. There is a fifth white band in order to indicate the type of resistor. I'm having a hard time sourcing this … 4th color code : resistance tolerance-J (±5%) - gold color. I'm a newbie that is stumped on a particular fusible resistor. For the 5 band resistor: 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. 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. RESISTOR COLOR CODE––––––––––––....––––––.. 12 7. 4.
