7.5K Ohm 0.1W 0603 1% SMD Resistor

If your board needs a 7.5k 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 7.5k ohm resistor in a small rectangular surface-mount body, built for precise resistance in solar inverters and other high-performance electronics where a steady value must hold. It fits power control, voltage division, and signal work that needs a fixed 7.5k 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 7.5k ohm 1% resistor holds its 7.5k ohm value within 1%, so a board that calls for 7.5k ohm gets between 7,425 and 7,575 ohm. The 7.5k ohm value is a high value: it passes only a small current at the same voltage, so it fits sensing, dividing, and control 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 7.5k ohm 0603 resistor for power control, where it sets a level or limits a current without wasting power, and for voltage division, where it takes a share of the voltage so the next stage sees the right level. It also fits signal work, where a steady high resistance keeps a signal clean without loading the circuit down. You can check the value from the marking: the 4-digit value code for this part is 7502, which reads as 75 followed by two more zeros, or 7,500 ohm. The EIA-96 code for the same value is 85B, where 85 stands for 750 and B means ×10.

Checks before you order

• Value: your board list must call for 7.5k ohm. A nearby value is not the same part — if your board needs a different value, stop and check the board list again. A 200k 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 low-power part, so even a small voltage across it makes real power — do not run it near its limit.
• Voltage: the voltage across this part must stay at or below about 27.4V in steady use. At this value the power rating is the real limit: at 75V the part would use about 0.75W, 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 7.5k 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 150 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. 7.5k ohm is the plain name from its value. 7.5k ohm resistor is the name buyers use with the unit spelled out. 7.5k ohm 0603 resistor is the name buyers use when the body size matters. SMD resistor is the name for its surface-mount style. 7.5k ohm 1% is the short name that carries the value and the tolerance together. If your board list calls for 7.5k 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 7.5k ohm mean?

It means 7,500 ohms of resistance. The letter K stands for kilo, or one thousand, so 7.5k ohm is 7.5 × 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 7.5k ohm, so between 7,425 and 7,575 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 7502 marking on the body?

It is the 4-digit value code for this part: 75 stands for the digits 75, and the last 2 means two more zeros, so 7502 means 7,500 ohm. The 3-digit code for the same value is 752, and the EIA-96 code is 85B, where 85 stands for 750 and B means ×10.

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

No. At 7.5k ohm the 0.1W rating is the limit that matters: it caps the steady voltage at about 27.4V. At 75V this part would use about 0.75W, 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. A magnifier helps, because the part and its marking are very small.

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 as a 7.5K ohm 0603 SMD resistor, a compact and reliable component for high-performance electronics and solar inverters, with 1% tolerance for precise resistance and consistent, accurate power control, 0.1W power rating, for space-constrained applications, with excellent thermal stability and low noise, for renewable energy systems, for designing or repairing solar inverters, with high-precision design that minimises energy loss so a solar inverter runs at peak efficiency — and that use still stands.
