750 Ohm 0.25W 1206 1% SMD Resistor

If your board needs a 750 ohm resistor, and the old part is a 1% 0.25W chip in a 1206 body, this is the part to order. It is a 750 ohm resistor in a small rectangular surface-mount body, built for precision work in solar inverters and other electronic circuits where a steady mid value must hold. It fits current limiting, voltage division, and power management jobs that need a fixed 750 ohm value at up to 0.25W. It does not fit jobs that need a different resistance value, a through-hole body, or more than 0.25W 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 750 ohm 1% resistor holds its 750 ohm value within 1%, so a board that calls for 750 ohm gets between 742.5 and 757.5 ohm. The 750 ohm value is a useful middle value: it passes more current than a high-value part, so it fits current limiting and power work, while the 0.25W rating in the 1206 body gives it more room for heat than the smaller 0603 parts. The 1206 body is about 3.1 mm long, so it fits boards where a larger part would not.

Repair techs use a part like this as a 750 ohm 1206 resistor for current limiting, where it holds the current through a stage to a safe level, and for voltage division, where it takes a share of the voltage so the next stage sees the right level. It also fits power management, where a steady value keeps a supply stage stable. You can check the value from the marking: the 4-digit value code for this part is 7500, which reads as 750 followed by no more zeros, or 750 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 750 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 1206 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 0.25W, and that 0.25W 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 0.25W with room to spare.
• Voltage: the voltage across this part must stay at or below about 13.7V in steady use. At this value the power rating is the real limit: at 200V the part would use about 53W, far above its rating, even though 200V 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 750 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 1206 surface-mount body. Measure the old part and match it against the pads and the space on your board. The series body is about 3.10 mm long, 1.60 mm wide, and 0.55 mm high — if your old part is much smaller, check the board list again before you order. A 665K part in the same 1206 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 quarter 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. 750 ohm is the plain name from its value. 750 ohm resistor is the name buyers use with the unit spelled out. 750 ohm 1206 resistor is the name buyers use when the body size matters. SMD resistor is the name for its surface-mount style. 750 ohm 1% is the short name that carries the value and the tolerance together. If your board list calls for 750 ohm at 0.25W with 1% tolerance in a 1206 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 750 ohm mean?

It means 750 ohms of resistance. Ohm is the unit of resistance, so a 750 ohm part resists current flow by 750 ohms.

What does 1% mean, and what does 0.25W mean?

1% is the tolerance: the real resistance may sit up to 1% above or below 750 ohm, so between 742.5 and 757.5 ohm. 0.25W 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 7500 marking on the body?

It is the 4-digit value code for this part: 750 stands for the digits 750, and the last 0 means no more zeros, so 7500 means 750 ohm. The 3-digit code for the same value is 751, and the EIA-96 code is 85B, where 85 stands for 750 and B means ×10.

Can I use this part at 200 V if the power is small?

No. At 750 ohm the 0.25W rating is the limit that matters: it caps the steady voltage at about 13.7V. At 200V this part would use about 53W, far above its rating. The 200V figure is the series voltage limit, not a voltage you can use at this value.

How do I fit a 1206 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 3.1 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.

Use note kept from the old page: this part was listed before as a 750 ohm 1206 SMD resistor for precision and stability in electronic circuits, for power management work, with 1% tolerance for accurate and dependable resistance, used in solar inverters where consistent resistance matters for efficient energy conversion, compact and easy to fit in high-density boards — and that use still stands.
