The resistance value lies therefore between 5320 and 5880 Ω. Voltage Protection. Its blocking voltage varies from 50 volts (1N4001) to 1000 volts (1N4007). The electronic color code was developed in the early 1920s by the Radio Manufacturers Association. Diode Color ID Band Table This table is the information used by MOST diode manufacturers that use color banding on diodes. Band 2 Coding Band 1 Coding Band 3 Coding Band 4 Coding Band 5 Coding TC dots near Band 4 or 6 TC 1001. The 1N400x (or 1N4001 or 1N4000) series is a family of popular one-ampere general-purpose silicon rectifier diodes commonly used in AC adapters for common household appliances. Password. Uses for a diode include, current protection, AC/DC conversion, and capture/emitting light. This letter denotes the tolerance of the zener voltages. Personally, I think that MELF is disadvantageous, as it tends to roll. Joined Dec 11, 2020 10. Order: 100,000 Pieces Port: ... HS Code. Recently, a new coding system (the EIA-96) has appeared on precision SMDs. See Electronic color code on Wikipedia. Plastic MELF Package Diodes . Rectifiers (521) RF Diodes (17) Schottky Diodes & Schottky Rectifiers (515) Small Signal Switching Diodes (153) Zener Diodes (40) MOSFETs. Color code is used as they are cheap and can be printed on small components as well. Remedy for this is thin conformal coats. Number of Bands. The missing third ring could be interpreted as zero (black), making the red-yellow component a 24 Ohm resistor. Bidirectional resistor color code calculator (color to value and value to color). MELF is SMD! A diode is a simple electronic component which blocks current in one direction and allows it in the other. Contact Mouser (USA) (800) 346-6873 | Feedback. Some manufactures that make two color band diodes use the same color bands for different series of diodes. The first three bands provide the significant figures. 12 MONTHS. Colour, if significant, is shown in small type after the code letter. IGBTs. forward current, and max. MELF devices are usually diodes and resistors.. Still others may have metal casings. Aug 15, 2008 #1 Hello, I am fixing a switch mode power supply and a shorted zener is giving me a headache. Mouser offers inventory, pricing, & datasheets for MELF Diodes & Rectifiers. The electronic color code is a way of indicating the ratings or values of electronic components like resistors, capacitors, inductors and others. reverse voltage. Diode Color ID Band Table This table is the information used by MOST diode manufacturers that use color banding on diodes. Figure 1-27. There are three variations used: Four band code: This system is used for resistors with tolerances up to 5% using the E24 resistor series. check with tracker, do not see any signature up to 50 volt. Need help identifying diode (MELF, mini-MELF, DO213 package), Datasheets, Manuals & Parts Identification. Instructions; This tool is used to decode information for color banded axial lead resistors. Please confirm your currency selection: Mouser Electronics - Electronic … Register Now. Skip to Main Content (800) 346-6873. Each Semiconductor devices have a special numbering coding as per the specification of those components. The standard diode color code system is shown in figure 1-27. Calculate the resistance for 3 band, 4 band, and 5 band resistors by simply selecting the colors you’re using! In this way there were vast numbers of different numbers for devices many of which were virtually identical.
