0 Ohm 0.25W 1206 1% SMD Resistor

If your board needs a 0 ohm jumper in a 1206 body, and the old part is a 0.25W chip, this is the part to order. It is a 0 ohm 1206 SMD resistor in name, but it works as a flat link: it bridges two points on a board with almost no resistance, so it carries current instead of limiting it. It fits PCB trace bridging, board options, and repair jobs where a connection must be made or changed without redrawing the board.

It does not fit any job that needs real resistance — if your board list calls for 1 ohm or more, this part is the wrong pick. Check the checks below before you order, so the value, the body, and the current all match your board.

This is an original, high-quality part.

What it does

A normal resistor limits current. A 0 ohm jumper resistor does the opposite job: it joins two points on a board with a neat, solderable link, the way a short piece of wire would, but in the same flat chip body as the other resistors on the board. Repair techs use it to bridge a gap in a PCB trace, to select one of two circuit options at build time, to route a signal around a damaged track, or to ground a point that needs a solid connection. Because its resistance is near zero, the voltage drop across it is near zero too, so it does not change the circuit the way a real resistor would.

This 0 ohm 1206 smd part is built as a thick film chip with wraparound ends that solder flat onto the board, in the 1206 body about 3.1 mm long. Its small size suits dense boards, and it works with normal reflow soldering and automated assembly. It is a chip resistor in form, but a jumper in function — judge it by its current, not by its power rating.

Key features

• 0 ohm nominal — a jumper link, not a resistance value
• Maximum resistance less than 50 mΩ
• Maximum current 3.5 A (see the gates note on the source)
• 0.25W body size class (RC1206) at 70°C ambient
• 1206 body: about 3.10 mm × 1.60 mm × 0.55 mm
• Thick film chip, surface mount, no polarity — fits either way round
• Wide temperature range: −55°C to +155°C
• Value code 0000 (jumper code)

Checks before you order

• Value: your board list must call for 0 ohm. If it calls for any real resistance — even 1 ohm — this part is the wrong pick, because a jumper passes current almost freely while a 1 ohm part still drops voltage. Do not order this part as a stand-in for a low-value resistor.
• Current, not power: the limit that matters for a jumper is current, not watts. The 0.25W in the name is the body size class — it does not tell you how much current this link can carry. The cross-check series document gives 3.5 A as the maximum current for a 1206 jumper, so keep your circuit current well inside that. If your circuit carries heavy current, stop and check the board design before you order. A 665K part in the same 1206 body is a resistor, not a jumper, and is a different job.
• Do not use it as a fuse: a 0 ohm jumper is not a fuse and must never be fitted where a fuse belongs. It will not break the circuit at a set current, so a fault will pass straight through it. If the old part was a fuse, order a fuse.
• Tolerance: the 1% in the name means nothing at 0 ohm — 1% of zero is zero. What matters is that the real resistance is very small, under 50 mΩ by the series jumper rule. Do not treat it as a resistance range.
• 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 10K part in the same 1206 body is a resistor, not a jumper, and is a different job.
• Fit for the job: a through-hole 0 ohm link is the same idea in a different form, but it mounts through holes, not onto pads — do not order a through-hole jumper for a surface-mount board. Match the form first, then the value.

Specifications

Other names for the same part (good to know)

Shoppers and repair techs call this same part by a few names. 0 ohm 1206 is the short name from its value and its body size. 0 ohm resistor is the plain name from its value. 0 ohm jumper resistor is the name buyers use when the jumper job matters. 0 ohm 1206 smd is the name buyers use when the size and the surface-mount style matter. 1206 jumper is the short name from its body size and its job. If your board list calls for 0 ohm in a 1206 surface-mount body, this page is the right match. Do not judge by size alone — check that the board really needs a jumper, not a resistor.

Frequently Asked Questions

Is a 0 ohm resistor really zero ohms?

Not exactly zero. It is a link with a very small resistance, under 50 mΩ by the series jumper rule, close enough to zero that the circuit treats it as a wire. It is sold as a jumper, not as a measured resistance.

What does 0.25W mean for a 0 ohm part?

It is the body size class — the same 1206 body as the 0.25W resistors in this family. It is NOT a current limit. For a jumper, current is the limit that matters, and the cross-check series document gives 3.5 A as the maximum current for a 1206 jumper.

What does 1% mean for a 0 ohm part?

Nothing useful — 1% of zero is zero. The 1% comes from the family naming, not from a real tolerance band on this part. Do not treat it as a resistance range.

Can I use this part instead of a wire?

Yes, that is what it is for — it bridges two points on a board the way a wire link would, but in a neat flat chip body that solders like the other chip resistors. Use it for trace bridging, board options, and grounding links.

Can I use this part instead of a fuse?

No. A jumper will not break at a set current, so it gives no protection. If the old part was a fuse, order a fuse of the right rating.

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 0 ohm resistor for reliable electrical continuity and PCB trace bridging in solar inverter circuits, for efficient circuit routing and minimal resistance applications in power electronics, with the 1206 package suiting automated assembly, used for current flow management, grounding, signal transmission, circuit protection, and layout flexibility in solar inverters and energy-efficient designs — and that use still stands.
