This basic loan calculator will assist you determine the value of any SMD resistor.
Smd Component Markings Code And StrikeTo get started, input the 3 or 4 digit code and strike the Calculate switch or Enter.Therefore, when in question (and when its feasible) dont hesitate to make use of a multimeter tó double-check thé critical components.See furthermore the colour code loan calculator on this page for MELF and regular through-hole resistors. Most nick resistors are usually runs with a 3-digit or 4-digit code -- the statistical equivalent of the acquainted color code for through-hole elements. Recently, a new coding program (the EIA-96) has made an appearance on precision SMDs. Standard-tolerance SMD resistors are proclaimed with a simple 3-digit code. The very first two quantities will indicate the significant digits, and the third will end up being the multiplier, telling you the power of ten tó which the twó substantial digits must end up being multiplied (or how many zeros to add). Resistances of less than 10 ohms perform not possess a multiplier, the letter R can be used instead to suggest the placement of the decimal point. The 4-digit program code is used for tagging precision surface area position resistors. Its equivalent to the previous system, the only difference can be the number of substantial digits: the first three quantities will inform us the significant numbers, and the fourth will be the multiplier, showing the strength of ten tó which the thrée substantial digits must become increased (or how many zeros to include). Resistances of less than 100 ohms are proclaimed with the help of the letter R, suggesting the placement of the decimal point. Recently, a brand-new coding program (EIA-96) has appeared on 1 SMD resistors. It is made up of a three personality program code: the first 2 quantities will tell us the 3 significant numbers of the resistor worth (discover the lookup desk below) and the 3rd marking (a letter) will reveal the multiplier. For illustration: 1 2 2 1.2k 1. Some manufacturers underline all three digits -- perform not befuddle this with the program code utilized on reduced value present sensing resistors. Current sensing SMDs can furthermore be runs with a long pub on top ( 1m5 1.5m, R001 1m, etc.) or a lengthy bar under the program code ( 101 0.101, 047 0.047). The underline is certainly used when the beginning R has to end up being omitted expected to the limited space on the resistors entire body. ![]() ![]() Use this desk as a manual just, and often consult the parts datasheet for the exact value. In most cases, however, youll see that a surface mount resistor proclaimed with the 3-digit code offers a tolerance of 5 and a resistor noted with 4-digit code or the fresh EIA-96 code provides a patience of 1 or less. There are many exclusions to this rule, so constantly check out the manufacturers datasheet, specifically if the elements tolerance is usually vital for your program.
