15 Ohm 0.25W 1206 1% SMD Resistor

If the board list calls for a 15 ohm resistor in a 1206 footprint, and the old part is a 1% chip resistor, this is the part to order. It is a 15 ohm resistor rated at 0.25 W with ±1% tolerance, in a 1206 body about 3.1 mm long. It fits current limiting, sensing, and damping work where a low, steady resistance is needed. It does not fit a 0603 or 0805 footprint, a through-hole board, or any circuit that pushes more than 0.25 W or more than about 129 mA through it. Check the checks below before you order, so the value, the size, and the current 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 15 ohm resistor is a low-value resistor, often used to limit current into a stage, to damp ringing on a line, or to sense current by the small voltage it drops. The 1% tolerance means a new part measures between 14.85 Ω and 15.15 Ω, which keeps current limits and sense readings 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 15 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.

Key features

• 15 Ω resistance, ±1% tolerance
• 0.25 W power rating at 70 °C
• Maximum working voltage 200 V
• Temperature coefficient ±100 ppm/°C
• 1206 (3216 metric) body, 3.10 × 1.60 × 0.55 mm
• Thick-film chip resistor, surface mount, no polarity — fits either way round
• Working temperature −55 °C to +155 °C, with power derated above 70 °C

Checks before you order

• Value: the board list must say 15 Ω — not 15 kΩ. A 15 kΩ part is one thousand times larger and will not do this job. If the old part is marked 15R0, that is the same 15 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.
• Current and power: at 15 Ω, 0.25 W means about 1.94 V and about 129 mA at most. Work out the real current in your circuit first — at such a low value, even a small voltage gives a large current, and the power limit is easy to cross by mistake.
• 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 75 ohm part, is a different job, not a swap for this one. Match the value first, then the size, then the current.

Other names for the same part (good to know)

Shoppers and repair techs call this same part by a few names. 15 ohm resistor is the plain name from its value. 15 ohm 1206 resistor is the name buyers use when the size matters. 15 ohm SMD resistor is the name buyers use when they search by type and value. 15R0 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 15R0 on a 1206 body, and your board list says 15 Ω at 1%, this page is the right match. Do not confuse it with a 15 kΩ part — that is a different value entirely.

Frequently Asked Questions

What does 15R0 mean on the body?

It means 15.0 ohms. The R marks the decimal point, so 15R0 reads as 15.0 Ω. It does not mean 15 kΩ.

How much current can this part carry?

At its 0.25 W rating and 15 Ω, the most is about 129 mA, at about 1.94 V. In your real circuit, keep both the power and the current inside the limits in the table.

Why does current matter more than voltage here?

Because the value is low. A small voltage across 15 Ω already gives a large current, so the 0.25 W power limit is reached at under 2 V. Check the current first, not the voltage.

Can I use this part in an 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 high-precision surface-mount component for stable resistance in demanding electronic circuits and compact circuit designs, used as a trusted choice for solar inverter components and precision applications needing consistent resistance with minimal deviation — and that use still stands.
