We Provide 20 for you about smd inductor marking code- page 1 These are smaller in size. 68X = 499 x 0.1 = 49.9Ω
Includes guides on tools, soldering, choosing & constructing a kit, Starting from the band closest to the one end, this color code sequence is identified. Electronics Assistant includes all these calculators and more in a However, for smaller inductors, abbreviation or text is used because there may not be enough room , for printing the actual value on it. The 4-digit code is used for marking precision surface mount resistors.
Generally these are coded according to the top colored dot on the surface. Electric Lawn Mowers
Not sure where to start? Best Function Generator Kits In the inductor the first band is red; according to the above table the number associated with this color is 2. Surface Mount Device(SMD) or Chip Inductor Codes. Generally these RF variable inductors have the size and voltage specifications marked on the side of the inductors. When no gold band is present in bands 2 or 3, band 4 is a multipier band. The inductance of an inductor can be calculated with the colors of the bands. Inductors can have four or five bands. From this top dot we have to calculate the inductor value in clockwise direction. The fourth band represents the tolerance. Electronics Repair Tool Kit Beginners Generally these are coded according to the top colored dot on the surface. An inductor establishes a magnetic field when current passes through it. The colour bands will be displayed below on the image of the inductor. Note: The program was tested rigorously, but it still may have a few bugs. For inductors of a very small physical size, coloured dots may be used instead of bands. The tolerance for F = 1%. The inductance is calculated by multiplying the significant number by ten to the power of the value of the third band. How to test diodes, transistors, Zeners, LEDs and MosFets. Soldering Stations Bands 2 and 3 represent basic value, and band 4 gives the number of zeros. The color coding system for inductors is very similar to that of resistors, especially in case of molded inductors. Take your favorite fandoms with you and never miss a beat. Check out our wide range of products. Looking for smd inductor marking code ? Inductor Value Identification using Text Marking, 5-Band Inductor Color Code (Military Standard Inductor Color Code), 5-Band Inductor Color Code Example for the Values Equal or Higher Than 10 uH, Surface Mount Device (SMD) or Chip Inductor Codes. These are also similar to chip inductors.
a chip resistor marked with the standard 3 digit code and a short bar below the marking denotes a precision (1% or less) resistor with a value taken from the E24 series (these values are usually reserved for 5% resistors). • Know the EIA and military standard colour codes for inductors. The inductance of an inductor can be calculated with the colors of the bands. 1002 = 100 x 102 (100) = 10000Ω or 10kΩ
SMD devices are, by their very nature, too small to carry conventional semiconductor type numbers. Here you can find the latest products in different kinds of smd inductor marking code. For this marking, micro Henry is the fundamental unit of measurement (even if no units are given). It is to be noted that, for inductors which are rated lower than 10nH, the third dot will not act like a multiplier. Inductor color code . can be calculated for E6 to E192 series, and calculation results can be printed or saved. The above inductor consists of following colors. The 3-digit code. Inductors can be marked by colored bands or colored dots. Best Robot Kits Kids Thus the value of this inductor is 52 103=52,000 nH. 3d Printer Kits Buy Online THE SMD CODEBOOK SMD Codes. Electronics Component Kits Beginners In multi-dot colored representation, inductors are marked with three color dots. Arduino Sensors googletag.cmd.push(function() { googletag.display("div-gpt-ad-1527869606268-8"); }); Inductor values can be determined mainly by two ways, namely text coding and color coding methods. The inductance of an inductor can be calculated with the colors of the bands. Three digit values are in nano Henries (nH) or micro Henries (μH), depending on manufacturers choice Click here to download Electronics Assistant FREE! Because of this size, the value of inductor is marked with a single of multiple color dots. Best Python Books Led Strip Light Kits Buy Online There are many exceptions to this rule, so always check the manufacturer's datasheet, especially if the component's tolerance is critical for your application. Brand: Campus Component. troubleshooting and more. Best Iot Starter Kits http://www.vikingamerica.com/ftp/NL.pdf, © 2007− 2020 Eric Coates MA BSc. Thus the inductor value is 27 X 10 uH = 270 uH with a tolerance rating of ±5%. Recently, a new coding system (EIA-96) has appeared on 1% SMD resistors.

It's similar to the previous system, the only difference is the number of significant digits: the first three numbers will tell us the significant digits, and the fourth will be the multiplier, indicating the power of ten to which the three significant digits must be multiplied (or how many zeros to add). The first two numbers will indicate the significant digits, and the third will be the multiplier, telling you the power of ten to which the two significant digits must be multiplied (or how many zeros to add). First two digits, i.e., 2 and 2 represent the first two digits of the inductor value.

If bands 2,3 and 4 are red, gold, red the value would be 2.2 µH, If bands 2,3 and 4 are gold, yellow, violet the value would be 0.47 µH (470nH). The first and second colored dots on the chip indicate the inductance in nano Henries and the third dot indicates the multiplier as shown in below. Rs 35/ Piece Get Latest Price. In a single color dot, colored dot is represented on one end or middle of the part as shown in below figure. These dots do not indicate the polarity.
Five band inductors have an additional silver band at the beginning, which is a military identifier. (Revision 14.01 18th July 2020).

Inductor Value Identification using Color Coding.
102 = 10 x 102 (100) = 1000Ω or 1kΩ
Best Jumper Wire Kits To get started, input the 3 or 4 digit code and hit the "Calculate" button or Enter. So, when in doubt (and when it's possible) don't hesitate to use a multimeter to double-check the critical components. Diy Digital Clock Kits Inductor color code; Inductor codes; Inductive voltage divider; Air core inductor; Inductors in series; Inductors in parallel; Inductive reactance; Related. Now, it is to be noted that no units are given, hence this value is in micro Henry (µH).
If bands 2, 3 and 4 are red, violet, orange the value would be 27000 µH. It is to be noted that the result of this color coded value is in the unit of micro Henry (µH). Index.
