8.2k Ohm 0.1W 0603 1% SMD Resistor

If your board needs an 8.2k ohm 0.1w resistor, and the old part is a 1% 0.1W chip in a 0603 body, this is the part to order. It is an 8.2k ohm resistor in a small rectangular surface-mount body, built for stable and reliable performance in solar inverters and other power management applications where a steady mid value must hold. It fits voltage regulation and circuit protection jobs that need a fixed 8.2k ohm value at up to 0.1W. It does not fit jobs that need a different resistance value, a through-hole body, or more than 0.1W of power. Check the checks below before you order, so the value, the power, the voltage, and the body 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 small flat part that solders straight onto the pads of a board, with metal ends that make the contact. This 8.2k ohm 1% resistor holds its 8.2k ohm value within 1%, so a board that calls for 8.2k ohm gets between 8,118 and 8,282 ohm. The 8.2k ohm value is a mid value: it passes far less current than a low-value part at the same voltage, so it fits regulation and signal work rather than heavy load work, while the 0603 body handles a tenth of a watt. The 0603 body is about 1.6 mm long, so it fits boards where a larger part would not.

Repair techs use a part like this as an 8.2k ohm 0603 resistor for voltage regulation, where it takes a share of the voltage so the next stage sees the right level, and for circuit protection, where a steady mid resistance keeps the current in check. It also fits power management, where a steady mid resistance sets a level without wasting power. You can check the value from the marking: the 4-digit code for this part is 8202, and the 3-digit code is 822. The K-code for the same value is 8K2, where the K is the decimal point, so 8K2 means 8.2K ohm. There is no EIA-96 code for 8.2K ohm, because 8.2K is an E24 value only — the nearest E96 value is 8.25K ohm.

Checks before you order

• Value: your board list must call for 8.2k ohm. A nearby value is not the same part — if your board needs a different value, stop and check the board list again. A 10K part in the same 0603 body is a different value for a different job, not a swap for this one.
• Power and heat: the power this part turns into heat must stay at or below 0.1W, and that 0.1W counts only up to 70°C ambient — above that, the safe power drops, so check the derating for your real working temperature. Work out the power from your real voltage and current (power = voltage × current) and keep it inside 0.1W with room to spare.
• Voltage: the voltage across this part must stay at or below about 28.6V in steady use. At this value the power rating is the real limit: at 75V the part would use about 0.69W, far above its rating, even though 75V is the series voltage limit. Work out the voltage from your circuit before you order.
• Tolerance: the real value may sit up to 1% away from 8.2k ohm. If your circuit needs tighter than 1%, this part is the wrong pick — do not hope the part you get sits near the middle. Do not swap in an 8.25k ohm part: 8.25K is a different E96 value, not the same part.
• Body and fit: your board must take a 0603 surface-mount body. Measure the old part and match it against the pads and the space on your board. The series body is about 1.60 mm long, 0.80 mm wide, and 0.45 mm high — if your old part is much bigger, check the board list again before you order. A 100 ohm part in the same 0603 body is a different value for a different job, not a swap for this one.
• Fit for the job: if your circuit only needs a fraction of a tenth of a watt, this part still works. Match the value first, then the power, then the body — a through-hole resistor is the wrong shape for a surface-mount board, even if the value matches.

Specifications

Other names for the same part (good to know)

Shoppers and repair techs call this same part by a few names. 8.2k ohm 0.1w is the plain name from its value and power. 8.2k ohm resistor is the name buyers use with the unit spelled out. 8.2k ohm 0603 resistor is the name buyers use when the value and the body size both matter. SMD resistor is the name for its surface-mount style. 8.2k ohm 1% is the short name that carries the value and the tolerance together. If your board list calls for 8.2k ohm at 0.1W with 1% tolerance in a 0603 body, this page is the right match. Do not judge by size alone — check the value, the power, and the tolerance too.

Frequently Asked Questions

What does 8.2k ohm mean?

It means 8,200 ohms of resistance — the part resists current flow by 8,200 ohms.

What does 1% mean, and what does 0.1W mean?

1% is the tolerance: the real resistance may sit up to 1% above or below 8.2k ohm, so between 8,118 and 8,282 ohm. 0.1W is the power rating: the most power the part can turn into heat without damage, rated at 70°C ambient, with less allowed as it gets hotter.

What is the 8K2 marking on the body?

It is the K-code for this part: the K is the decimal point, so 8K2 means 8.2K ohm. The 4-digit code for the same value is 8202, and the 3-digit code is 822. There is no EIA-96 code for 8.2K ohm, because 8.2K is an E24 value only; the nearest E96 value is 8.25K ohm.

Can I use this part at 75 V if the power is small?

No. At 8.2k ohm the 0.1W rating is the limit that matters: it caps the steady voltage at about 28.6V. At 75V this part would use about 0.69W, far above its rating. The 75V figure is the series voltage limit, not a voltage you can use at this value.

How do I fit a 0603 chip resistor?

Solder it onto the matching pads on the board — it has no leads, so it sits flat on the pads. Check the pad spacing against the 1.6 mm body before you solder, use a fine tip and a small amount of solder, and do not overheat the part.

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.
