i found this resistor http://www.mouser.com/ds/2/427/cmfind-239942.pdf there is something interesting, the PPM per celcious what is the meaning of this? what is PPM?

raschemmel: Seriously dude ? You never heard of Parts Per Million ? as someone who his native language is not english, no i have not.. can you please explain what is the meaning in temperture whise

It is the amount the R value changes for every degree the temperature changes. 100PPM per deg C means the R increases 100 ohms for every 1M ohm for every degree the temperature increases. Or by the same ratio for other values. EG, 10 ohms for every 100k or 1 ohm every 10k. Weedpharma

To express something (the variation of something in this case) in ppm is a more comfortable way of saying the same in "%" 100 PPM is 100/1 000 000 => 1 / 100 000 => 0.000001 => 0.0001 % that, in this case, means that the resistance of the item varies a 0.0001 % (per degree ºC of variation in its te…

Hello i just wanted to comment on this subject my self. I also never heard of ppm into i seen this post and thank you for sharing with us what it means and how it works.

PPM is also used extensively in gas and similar concentrations. EG, the garage had 100 PPM of carbon monoxide. Tells us the concentration of the gas with respect to normal air. You have probably seen it many times, just not registered what it meant. Weedpharma

Teil pro million, in german. Generally though the abbreviation ppm is universal. It has many meanings though depending on context.

The change in resistance due to a change in temperature is normally quite small over a particular temperature range. This is because the manufacturer has chosen a material having a resistivity not greatly influenced by temperature. That is, the material (and so the resistor) has a low TEMPERATURE C…

percent (%) = 1 part in 102 permil (‰) = 1 part in 103 permyriad (‱) = 1 part in 104 parts per million (ppm) = 1 part in 106 parts per billion (ppb) = 1 part in 109 parts per trillion (ppt) = 1 part in 1012
