806K Ohm 0.1W 0603 1% SMD Resistor

 

If your board needs a 806k ohm resistor, and the old part is a 1% 0.1W chip in a 0603 body, this is the part to order. It is a 806k ohm resistor in a small rectangular surface-mount body, built for precision work in solar inverters and other electronic circuits where a steady very high value must hold. It fits voltage division, signal work, and sensing jobs that need a fixed 806K 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 806k ohm 1% resistor holds its 806K value within 1%, so a board that calls for 806K gets between 797.94K and 814.06K. The 806K value is an E96 value — a fine step in the precision series — which is why it fits feedback and sensing, where the exact value sets how the circuit behaves. The 0603 body is only about 1.6 mm long, so it fits boards where space is tight.

Repair techs use a part like this as a 806k ohm 0603 resistor for voltage division, where it takes a share of the voltage so the next stage sees the right level, and for sensing, where a fixed very high resistance sets a level without loading the circuit down. It also fits signal work, where a steady high value keeps a signal path clean. You can check the value from the marking: the EIA-96 code for this part is 88D, which reads as 806 times 1,000, or 806,000 ohm. The 4-digit value code for the same part is 8063.

Checks before you order

• Value: your board list must call for 806K. A nearby value is not the same part — an 800K part is close but not the same E96 value, so if your board needs 806K, stop and check the board list again. A 270K 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. This is a small part with little room for heat, so do not run it near its limit.
• Voltage: the voltage across this part must stay at or below the 75V series cap. From power alone the figure would be higher (about 284V at 0.1W), so the 75V cap is the limit that binds — stay below it. Above that, this part is the wrong pick.
• Tolerance: the real value may sit up to 1% away from 806K. If your circuit needs tighter than 1%, this part is the wrong pick — do not hope the part you get sits near the middle.
• 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 15K 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.

Other names for the same part (good to know)

Shoppers and repair techs call this same part by a few names. 806k ohm is the plain name from its value. 806k ohm resistor is the name buyers use with the unit spelled out. 806k ohm 0603 resistor is the name buyers use when the body size matters. SMD resistor is the name for its surface-mount style. 806k ohm 1% is the short name that carries the value and the tolerance together. If your board list calls for 806K 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 806K mean?

It means 806,000 ohms of resistance. K stands for kilo, which means one thousand, so 806K is 806 × 1,000 ohms. It is an E96 value, a fine step in the precision resistor series.

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 806K, so between 797.94K and 814.06K. 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 88D marking on the body?

It is the EIA-96 code printed on a 1% 806K 0603 chip. In the EIA-96 table, 88 stands for 806 and D stands for a multiplier of 1,000, so 88D means 806 times 1,000, or 806,000 ohms. The 4-digit value code for the same part is 8063.

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

No. The maximum working voltage is 75 V, and it applies even when the power is tiny. At 806K the current is always small, so voltage, not power, is the limit to watch.

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. A magnifier helps, because the part and its marking are very small.

What is the price of this part?
