68K Ohm 0.25W 1206 1% SMD Resistor

If the board list calls for a 68k resistor in a 1206 footprint, and the old part is a 1% chip resistor, this is the part to order. It is a 68k ohm resistor rated at 0.25 W with ±1% tolerance, in a 1206 body about 3.1 mm long. It fits precision circuits where the resistance must stay close to 68 kΩ, such as divider, bias, and sensing stages. 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 68k resistor is a mid-to-high value resistor, often used to set a bias point, divide a voltage down, or limit current to a very small level without loading the stage before it. The 1% tolerance means a new part measures between 67.32 kΩ and 68.68 kΩ, which keeps divider ratios and bias points 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 68k 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 68 kΩ. A 6.8 kΩ part or a 680 kΩ part is a different part, even though the digits look close. If the old part is marked 6802, that is the same 68 kΩ value. The code 683 is the 5% version’s code — if your old part says 683 and your list says 1%, check the list again before ordering.
• 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 voltage: at 68 kΩ, 0.25 W means about 130.4 V and about 1.92 mA at most. Work out the real voltage in your circuit and keep it at or below 200 V, and keep the power at or below 0.25 W.
• 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 power.

Other names for the same part (good to know)

Shoppers and repair techs call this same part by a few names. 68k resistor is the short name from its value. 68k ohm resistor is the plain name with the unit spelled out. 68k 1206 resistor is the name buyers use when the size matters. 6802 resistor is the name from the code printed on the body, where 680 are the value digits and 2 means two zeros, giving 68,000 ohms. 1206 SMD resistor 1% is the name buyers use when they search by size and tolerance. If you see 6802 on a 1206 body, and your board list says 68 kΩ at 1%, this page is the right match. Do not judge by size alone — check the value too.

Frequently Asked Questions

What does 6802 mean on the body?

It means 68 followed by two zeros, which is 68,000 ohms, or 68 kΩ. The first three digits are the value digits and the last digit is the number of zeros to add.

Is 683 the same part?

No. The code 683 is the 3-digit code used for the 5% version of the same value. This page is the 1% part, marked 6802. The value is the same, but the tolerance is tighter, so check your board list before swapping.

How much voltage can this part take?

Up to 200 V of working voltage, and up to 0.25 W of power, at the same time. At 68 kΩ the power limit is reached at about 130.4 V, so in most circuits the power limit matters first.

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?

Use note kept from the old page: this part was listed before as a high-precision surface-mount component for stable and reliable electrical performance in compact electronic designs and precision applications requiring consistent resistance values — and that use still stands.
