Description
If the board list calls for a 75 ohm resistor in a 1206 footprint, and the old part is a 1% chip resistor, this is the part to order. It is a 75 ohm resistor rated at 0.25 W with ±1% tolerance, in a 1206 body about 3.1 mm long. It fits signal work where the resistance must stay close to 75 Ω, which is a common value for matching signal lines. It does not fit a 0603 or 0805 footprint, a through-hole board, or any circuit that needs more than 0.25 W or more than 200 V across it. Check the checks below before you order, so the value, the size, and the power all match your board.
This is an original, high-quality part.
What it does
A resistor limits current and sets a voltage in a circuit. A 75 ohm resistor is a low-value resistor, often used to match a signal line so the signal travels cleanly without reflections, and to limit current in a small part of a circuit. The 1% tolerance means a new part measures between 74.25 Ω and 75.75 Ω, which keeps matched lines and divider circuits close to their design values. The ±100 ppm/°C temperature coefficient means the value moves only about 0.01% per degree, so it stays steady as the board warms up.
This 75 ohm 1206 resistor is a thick-film chip resistor with wraparound ends that solder flat onto the board. Its 1206 SMD resistor 1% body is easy to place by hand and by machine, and it works with normal reflow soldering.

- Working temperature −55 °C to +155 °C, with power derated above 70 °C
Checks before you order
- Value: the board list must say 75 Ω. A 750 Ω part or a 7.5 Ω part is a different part, even though the digits look close. If the old part is marked 75R0, that is the same 75 Ω value.
- Size: the pads on your board must be for a 1206 body (about 3.1 × 1.6 mm). A 0603 or 0805 part is smaller and will not sit right on 1206 pads.
- Power and current: at 75 Ω, 0.25 W means about 4.33 V and about 57.7 mA at most. Work out the real voltage and current in your circuit and keep both inside the limits — a low-value resistor can draw more current than a high-value one at the same voltage.
- Tolerance: your circuit must accept ±1%. If the old part was 5%, this 1% part still works in its place, because it is tighter. If the old part was 0.1% or 0.5%, do not swap down to 1% without checking the circuit.
- Fit for the job: a different value on the same board, such as a 15 ohm part, is a different job, not a swap for this one. Match the value first, then the size, then the power.

Other names for the same part (good to know)
Shoppers and repair techs call this same part by a few names. 75 ohm resistor is the plain name from its value. 75 ohm 1206 resistor is the name buyers use when the size matters. SMD resistor 75 ohm is the name buyers use when they search by type and value. 75R0 resistor is the name from the code printed on the body, where R marks the decimal point. 1206 SMD resistor 1% is the name buyers use when they search by size and tolerance. If you see 75R0 on a 1206 body, and your board list says 75 Ω at 1%, this page is the right match. Do not judge by size alone — check the value too.
Frequently Asked Questions
What does 75R0 mean on the body?
It means 75.0 ohms. The R marks the decimal point, so 75R0 reads as 75.0 Ω.
Why is 75 ohms a common value?
Because many signal and video lines are built for 75 ohm impedance. A 75 ohm resistor matches such a line so the signal travels cleanly instead of reflecting back.
How much current can this part carry?
At its 0.25 W rating and 75 Ω, the most is about 57.7 mA, at about 4.33 V. In your real circuit, keep both the power and the voltage inside the limits in the table.
Can I use a 75 ohm part in a 0805 footprint?
No. The value may match, but the body is a different size and will not sit right on the pads. Order the size your board was made for.
Does this resistor have a polarity?
No. A chip resistor works either way round. You can solder it in either direction and the circuit works the same.
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 compact surface-mount resistor for accurate resistance control, used for signal matching, current limiting, voltage division, impedance control, and general PCB work, in communication circuits, signal lines, audio circuits, power control boards, repair work, and compact electronic devices where stable and precise resistance is required — and that use still stands.
