0 ohm 1W 2512 1% SMD RESISTOR

If your board needs a 0 ohm 1w resistor, and the old part is a 1W jumper in a 2512 body, this is the part to order. It is a 0 ohm jumper in a small rectangular surface-mount body, built to bridge two points on a board with almost no resistance, for solar inverters and other power electronics where a clean current path must hold. It fits grounding, circuit debugging, and signal routing jobs that need a solid bridge at up to 2.0A steady current. It does not fit jobs that need a real resistance value, a through-hole body, or more than 2.0A of steady current. Check the checks below before you order, so the current, the voltage, and the body all match your board.

This is an original, high-quality part.

What it does

A jumper is a zero-ohm bridge: it joins two points on a board so current can flow straight through, the way a short length of wire would. A chip jumper 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 0 ohm 2512 resistor is a jumper, not a resistor with a value — its resistance stays under 50mΩ, so it adds almost no resistance to the path. The 2512 body is about 6.35 mm long, so it fits boards where a smaller jumper would not carry the current, while the 1W rating gives it room for demanding energy systems. You can check the part from the marking: a jumper is marked “0”. There is no 4-digit code and no EIA-96 code for 0 ohm, because there is no resistance value to code.

Repair techs use a part like this as a 0 ohm 2512 resistor for circuit bridging, where it joins two tracks so the layout stays simple, and for grounding, where it gives a solid zero-ohm path to ground. It also fits circuit debugging, where a jumper can be fitted or removed to test one part of a board, and signal routing, where it carries a signal across the board without adding resistance. Do not use it where the circuit needs a real resistance value — a jumper passes almost everything, so it cannot limit current or drop voltage the way a resistor does.

Checks before you order

• Value: your board list must call for a 0 ohm jumper. A jumper is not a resistor value — if your board needs 10 ohm or any other value, this part is the wrong pick, so stop and check the board list again. A 22 ohm part in the same 2512 body is a different value for a different job, not a swap for this one.
• Current: the steady current through this part must stay at or below 2.0A. The 10.0A figure is a short-peak maximum only — at 10.0A a worst-case 50mΩ jumper would turn 5W into heat, far above its 1W rating, so never run it there in steady use. Work out the current from your real circuit and keep it inside 2.0A with room to spare.
• Voltage: the voltage across this part stays tiny in normal use, because the resistance is under 50mΩ — at 2.0A the drop is at most 0.1V. The 200V figure is the series voltage limit for the body, not a voltage you will see across a jumper. If your circuit puts a large voltage across this part, something else is wrong — check the circuit before you order.
• Tolerance: the 1% in the name is the part-number tolerance class. The jumper itself is specified by its maximum resistance (under 50mΩ), not by a 1% resistance value — do not expect it to measure a fixed resistance. If your circuit needs a set resistance value, order a resistor with that value, not a jumper.
• Body and fit: your board must take a 2512 surface-mount body. Measure the old part and match it against the pads and the space on your board. The series body is about 6.35 mm long, 3.10 mm wide, and 0.55 mm high — if your old part is much smaller, check the board list again before you order. A 0 ohm jumper in the smaller 0805 body is a different size and a lower power rating, not a swap for this one.
• Fit for the job: if your board only needs a bridge for a small signal current, this part still works, but match the current first, then the body — a through-hole wire link is the wrong shape for a surface-mount board, even if it carries the same current.

Specifications

Other names for the same part (good to know)

Shoppers and repair techs call this same part by a few names. 0 ohm 1w is the plain name from its value and power. 0 ohm resistor is the name buyers use with the unit spelled out. 0 ohm 2512 resistor is the name buyers use when the value and the body size both matter. SMD jumper is the name for what it does — a surface-mount bridge. 2512 smd resistor is the name buyers use when the body size matters most. If your board list calls for a 0 ohm jumper at 1W in a 2512 body, this page is the right match. Do not judge by size alone — check the current rating too.

Frequently Asked Questions

What does 0 ohm mean?

It means the part has almost no resistance — under 50mΩ. It is a jumper, a bridge that joins two points on a board so current flows straight through.

What is the 0 marking on the body?

It is the marking for a jumper: a single “0”. There is no 4-digit code and no EIA-96 code for 0 ohm, because there is no resistance value to code.

How much current can this jumper carry?

2.0A steady current. The 10.0A figure is a short-peak maximum only — never run it at 10.0A in steady use, because at that current a worst-case 50mΩ jumper would turn 5W into heat, far above its 1W rating.

Can I use this part as a resistor?

No. A jumper adds almost no resistance, so it cannot limit current or drop voltage the way a resistor does. If your circuit needs a resistance value, order a resistor with that value.

What size is a 2512 body?

About 6.35 mm long, 3.10 mm wide, and 0.55 mm high. The metric size code is 6332.

What is the price of this part?
