56K Ohm 0.1W 0603 1% SMD Resistor

 

If your board needs a 56k ohm resistor, and the old part is a 1% 0.1W chip in a 0603 body, this is the part to order. It is a 56k ohm resistor in a small rectangular surface-mount body, built for stable voltage division and signal work in solar inverters and other power electronics where a steady high value must hold. It fits voltage regulation, signal conditioning, and power supply jobs that need a fixed 56K value at up to 0.1W. It does not fit jobs that need a different resistance value, a through-hole body, or more than 0.1W of power. Check the checks below before you order, so the value, the power, the voltage, and the body all match your board.

This is an original, high-quality part.

What it does

A resistor limits current and drops voltage in a circuit. A chip resistor 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 56k ohm 1% resistor holds its 56K value within 1%, so a board that calls for 56K gets between 55.44K and 56.56K. The high value is the point here: at the same voltage, a 56K part passes far less current than a low-value part, which is why it fits voltage division and signal work rather than heavy load work. The 0603 body is only about 1.6 mm long, so it fits boards where space is tight.

Repair techs use a part like this as a 56k ohm 0603 resistor for voltage division, where it takes a share of the voltage so the next stage sees the right level, and for signal conditioning, where a fixed high resistance shapes or scales a signal without loading it down. It also fits power supply work, where a steady high value keeps a supply stage stable. You can check the value from the marking: the 4-digit value code for this part is 5602, which reads as 560 followed by 2 zeros, or 56,000 ohm. Some makers print the 3-digit code 563 on a body this small instead, and some print no marking at all, so the board list is the final check.

Checks before you order

• Value: your board list must call for 56K. A nearby value is not the same part — if your board needs a different value, stop and check the board list again. A 20K part in the same 0603 body is a different value for a different job, not a swap for this one.
• Power and heat: the power this part turns into heat must stay at or below 0.1W, and that 0.1W counts only up to 70°C ambient — above that, the safe power drops, so check the derating for your real working temperature. Work out the power from your real voltage and current (power = voltage × current) and keep it inside 0.1W with room to spare.
• Voltage: the voltage across this part must stay at or below about 74.8V in steady use. At this value the power rating is the limit that binds, by a hair: at 75V the part would use just over 0.1W, even though 75V is the series voltage limit. Work out the voltage from your circuit before you order.
• Tolerance: the real value may sit up to 1% away from 56K. If your circuit needs tighter than 1%, this part is the wrong pick — do not hope the part you get sits near the middle.
• Body and fit: your board must take a 0603 surface-mount body. Measure the old part and match it against the pads and the space on your board. The series body is about 1.60 mm long, 0.80 mm wide, and 0.45 mm high — if your old part is much bigger, check the board list again before you order. A 30K part in the same 0603 body is a different value for a different job, not a swap for this one.
• Fit for the job: if your circuit only needs a fraction of a tenth of a watt, this part still works. Match the value first, then the power, then the body — a through-hole resistor is the wrong shape for a surface-mount board, even if the value matches.

Other names for the same part (good to know)

Shoppers and repair techs call this same part by a few names. 56k ohm is the plain name from its value. 56k ohm resistor is the name buyers use with the unit spelled out. 56k ohm 0603 resistor is the name buyers use when the body size matters. SMD resistor is the name for its surface-mount style. 56k ohm 1% is the short name that carries the value and the tolerance together. If your board list calls for 56K at 0.1W with 1% tolerance in a 0603 body, this page is the right match. Do not judge by size alone — check the value, the power, and the tolerance too.

Frequently Asked Questions

What does 56K mean?

It means 56,000 ohms of resistance. K stands for kilo, which means one thousand, so 56K is 56 × 1,000 ohms.

What does 1% mean, and what does 0.1W mean?

1% is the tolerance: the real resistance may sit up to 1% above or below 56K, so between 55.44K and 56.56K. 0.1W is the power rating: the most power the part can turn into heat without damage, rated at 70°C ambient, with less allowed as it gets hotter.

What is the 5602 marking on the body?

It is the 4-digit value code for this part: 560 stands for the digits 560, and the last 2 means two more zeros, so 5602 means 56,000 ohms. Some makers print the 3-digit code 563 on a body this small instead, and some print no marking at all. There is no EIA-96 code for this value, because 56 is not an E96 series value.

Can I use this part at 75 V if the power is small?

No. At 56K the 0.1W rating is the limit that matters, by a hair: it caps the steady voltage at about 74.8V, and at 75V the part would use just over 0.1W. The 75V figure is the series voltage limit, not a voltage you can use at this value.

How do I fit a 0603 chip resistor?

Solder it onto the matching pads on the board — it has no leads, so it sits flat on the pads. Check the pad spacing against the 1.6 mm body before you solder, use a fine tip and a small amount of solder, and do not overheat the part. A magnifier helps, because the part and its marking are very small.

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 56K ohm 0.1W surface-mount resistor for stable resistance with minimal variation, with 1% tolerance for accurate performance in solar inverters and power supply systems, in the 0603 package for compact PCB designs, for precise voltage regulation and signal conditioning, for engineers and designers working with renewable energy solutions, built for long-term reliability in demanding environments — and that use still stands.
