200K Ohm 0.1W 0603 1% SMD Resistor

 

If your board needs a 200k 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 200k ohm resistor in a small rectangular surface-mount body, built for stable voltage regulation and signal control in solar inverters and other power management circuits where a steady high value must hold. It fits DC-DC converters, power supplies, and inverter systems that need a fixed 200k 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 200k ohm 1% resistor holds its 200k ohm value within 1%, so a board that calls for 200k ohm gets between 198,000 and 202,000 ohm. The 200k ohm value is a high value: it passes only a very small current at the same voltage, so it fits sensing, dividing, and regulation work, while the small 0603 body keeps it out of the way on crowded boards. 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 200k ohm 0603 resistor for voltage regulation, where it takes a share of the voltage so the next stage sees the right level, and for signal control, where a steady high resistance keeps a signal clean without loading the circuit down. It also fits power management, where a fixed high value sets a level without wasting power. You can check the value from the marking: the 4-digit value code for this part is 2004, which reads as 200 followed by four more zeros, or 200,000 ohm. The EIA-96 code for the same value is 30D, where 30 stands for 200 and D means ×1,000.

Checks before you order

• Value: your board list must call for 200k ohm. A nearby value is not the same part — if your board needs a different value, stop and check the board list again. A 7.5k 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. At this high value the current is always small, so the power stays low in normal use — do not run it near its limit all the same.
• Voltage: the voltage across this part must stay at or below 75V in steady use. At this value the series voltage cap is the limit that binds: the power formula alone would allow about 141V, but the 75V series limit comes first. Work out the voltage from your circuit before you order.
• Tolerance: the real value may sit up to 1% away from 200k 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.
• 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 820k 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. 200k ohm is the plain name from its value. 200k ohm resistor is the name buyers use with the unit spelled out. 200k ohm 0603 resistor is the name buyers use when the body size matters. SMD resistor is the name for its surface-mount style. 200k ohm 1% is the short name that carries the value and the tolerance together. If your board list calls for 200k 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 200k ohm mean?

It means 200,000 ohms of resistance. The letter K stands for kilo, or one thousand, so 200k ohm is 200 × 1,000 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 200k ohm, so between 198,000 and 202,000 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 2004 marking on the body?

It is the 4-digit value code for this part: 200 stands for the digits 200, and the last 4 means four more zeros, so 2004 means 200,000 ohm. The 3-digit code for the same value is 204, and the EIA-96 code is 30D, where 30 stands for 200 and D means ×1,000.

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

Yes, up to 75V. At 200k ohm the series voltage cap is the limit: at 75V this part uses only about 0.028W, well inside its 0.1W rating. Do not go above 75V, even though the power formula alone would allow about 141V — the 75V series limit comes first.

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?
