270 Ohm 0.1W 0805 1% SMD RESISTOR

If your board needs a 270 ohm chip resistor in the 0805 size with tight 1% tolerance, this is the part to order. It is a 270 ohm SMD resistor, 0.125W (1/8W), in the small rectangular 0805 (2012 metric) body, built for stable resistance control on modern circuit boards. It fits boards that call for a fixed 270 ohm value where the extra accuracy of 1% matters — signal paths, divider networks, biasing, current sensing at low levels, and general board repair. It does not fit jobs that need a different resistance value, a through-hole body, a bigger chip size, or more power than its rating allows. Check the checks below before you order, so the value, the tolerance, the power, and the footprint all match your board.

This is an original, high-quality part.

What it does

A resistor limits current and drops voltage in a circuit. A chip resistor does that job as a tiny rectangular block with metal ends that solder flat onto pads on the board — no leads, no holes. This 270 ohm 0805 part holds its 270 ohm value within 1%, so a board that calls for 270 ohm gets between 267.3 and 272.7 ohms. That tight band is the point of paying for a 1% part: where a 5% part could sit far enough off to shift a signal level or a divider ratio, this part stays close to the design value.

Repair techs use a part like this as a 270 ohm resistor for the same jobs a through-hole resistor does, but on boards where space is tight and the footprint is already 0805. It is an 0805 resistor, which means it fits pads made for the 0805 (2012 metric) size — about 2.0 mm long and 1.25 mm wide. It is an SMD resistor 1% part, so it suits work where accuracy matters more than power handling. Note carefully: 270 ohm is its own value. It is not a stand-in for any other value, and no other value on this site is presented here as its equal.

Checks before you order

• Value: your board list must call for 270 ohm. A nearby value is not the same part — if your board needs a different value, stop and check the board list again. A 560 ohm part in the same 0805 1% family is a different job, not a swap for this one.
• Footprint: your board pads must be made for the 0805 size. Measure the old part or the pads: about 2.0 mm long and 1.25 mm wide. A 0603 part is smaller and a 1206 part is bigger — neither sits right on 0805 pads.
• Power and heat: the power this part turns into heat must stay at or below 0.125W (1/8W). That is a small amount — at 270 ohm it takes only about 5.8V across the part to reach it. If your circuit pushes more power through this spot, this part is the wrong pick, even if the value matches.
• Voltage: the voltage across this part must stay at or below 150V, and inside the power limit at the same time. In practice the power limit binds first for this value, so check the power first.
• Tolerance: the real value may sit up to 1% away from 270 ohm. If your circuit needs tighter than 1%, this part is the wrong pick. If it only needs 5%, this part still works, but you are paying for accuracy you do not need.
• Soldering: this is a surface-mount part with no leads. Fit it with a soldering iron with a fine tip or hot air, and check the ends sit flat on both pads before you finish. A part soldered on one end only will read open or drift.
• Fit for the job: a 1.5K part in the same 0805 1% family is a different job, not a swap for this one. Match the value first, then the tolerance, then the footprint, then the power.

Other names for the same part (good to know)

Shoppers and repair techs call this same part by a few names. 270 ohm SMD resistor is the plain name from its value and its mounting style. 0805 resistor is the name buyers use for its size. 270 ohm 0805 is the short name that carries the value and the size together. SMD resistor 1% is the name for its accuracy class. 270 ohm resistor is the plain name on its own. If your board list calls for 270 ohm at 1% in an 0805 body, this page is the right match. Do not judge by size alone — check the value and the tolerance too.

Frequently Asked Questions

What does 270 ohm mean?

It means 270 ohms of resistance — a low value, far below one kilo-ohm. It passes much more current at a given voltage than a 1.5K part would, which is why the two values are never interchangeable.

What does 0805 mean, and what does 2012 mean?

0805 is the imperial size code for this chip: about 0.08 inches long and 0.05 inches wide. 2012 is the same size in metric: about 2.0 mm long and 1.2 mm wide. They are two names for the same footprint, not two different parts.

What does 1% tolerance mean?

It means the real resistance sits within 1% of 270 ohm, so between 267.3 and 272.7 ohms. That is much tighter than a 5% part, which is why 1% parts are used where a signal level or a divider ratio must stay accurate.

Is this part 0.1W or 0.125W?

It is 0.125W (1/8W). That is the standard rating for an 0805 chip resistor — the maker series documents and the specification block on this page both say 1/8W (0.125W) at 70°C. The 0.1W figure in the product title is from the old listing; 0.1W is the rating for the smaller 0603 size, not for this 0805 part.

How much power can this part handle?

Up to 0.125W at 70°C, with less allowed as it gets hotter. At 270 ohm that means only about 5.8V across the part reaches the power limit, so check the power in your circuit before you order — a part that matches on value but not on power will fail.

What is the price of this part?

Check the live price on the website. The price shown on the product page is the current one.

Use note kept from the old page: this part was listed before with only the general 0805 explanation — a passive two-terminal chip resistor, rectangular, with metal ends that join the board through solder, used across electronic equipment — and that use still stands.
