220 Ohm 0.25W 1206 1% SMD Resistor

If your board needs a 220 ohm 0.25w resistor, and the old part is a 1% 0.25W chip in a 1206 body, this is the part to order. It is a 220 ohm resistor in a small rectangular surface-mount body, built for stable and efficient electrical performance in solar inverters where a steady low value must hold. It fits voltage regulation, current limiting, and signal conditioning jobs that need a fixed 220 value at up to 0.25W. It does not fit jobs that need a different resistance value, a through-hole body, or more than 0.25W 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 220 ohm 1% resistor holds its 220 value within 1%, so a board that calls for 220 gets between 217.8 to 222.2 ohm. The 220 ohm value is a low value: at the same voltage it passes far more current than a mid-value part, so it fits regulation and limiting work rather than dividing work, while the 1206 body handles a quarter of a watt. The 1206 body is about 3.1 mm long, so it fits boards where a larger part would not.

Repair techs use a part like this as a 220 ohm 1206 resistor for current limiting, where it holds the current through a stage to a safe level, and for voltage regulation, where a steady low resistance keeps the voltage even. It also fits signal conditioning, where a fixed low resistance sets a level without wasting power. You can check the value from the marking: the 4-digit value code for this part is 2200, which reads as 220 followed by 1 zero, or 220 ohm. The 3-digit code for the same value is 221. There is no EIA-96 code for 220 ohm, because 220 is not an E96 value — the E96 series has 221 ohm instead.

Key features

• 220 Ohm (220 Ω) fixed resistance, ±1% tolerance

• Thick film chip construction, surface mount
• 1206 body: about 3.10 mm × 1.60 mm × 0.55 mm
• Maximum working voltage 200V (series limit — the 0.25W rating caps this value at about 7.4V)
• Temperature coefficient ±100 ppm/°C
• Wide temperature range: −55°C to +155°C
• 4-digit value code 2200; 3-digit code 221; no EIA-96 code (220 is E24 only)

Checks before you order

• Value: your board list must call for 220. A nearby value is not the same part — if your board needs a different value, stop and check the board list again. A 200 Ohm part in the same 1206 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 0.25W, and that 0.25W 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 0.25W with room to spare.
• Voltage: the voltage across this part must stay at or below about 7.4V in steady use. At this value the power rating is the real limit: at 200V the part would use about 182W, far above its rating, even though 200V 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 220. 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 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 100 Ohm part in the same 1206 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 quarter 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.

Specifications

Other names for the same part (good to know)

Shoppers and repair techs call this same part by a few names. 220 ohm 0.25w is the plain name from its value and power. 220 ohm resistor is the name buyers use with the unit spelled out. 220 ohm 1206 resistor is the name buyers use when the value and the body size both matter. SMD resistor is the name for its surface-mount style. 220 ohm 1% is the short name that carries the value and the tolerance together. If your board list calls for 220 at 0.25W with 1% tolerance in a 1206 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 220 mean?

It means 220 ohms of resistance.

What does 1% mean, and what does 0.25W mean?

1% is the tolerance: the real resistance may sit up to 1% above or below 220, so between 217.8 to 222.2 ohm. 0.25W 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 2200 marking on the body?

It is the 4-digit value code for this part: 220 stands for the digits 220, and the last 0 means no more zeros, so 2200 means 220 ohm. The 3-digit code for the same value is 221. There is no EIA-96 code for 220 ohm: 220 is an E24 value only, and the E96 series has 221 ohm instead, so do not use the code 31A here — 31A is 205 ohm, a different value.

Can I use this part at 200 V if the power is small?

No. At 220 the 0.25W rating is the limit that matters: it caps the steady voltage at about 7.4V. At 200V this part would use about 182W, far above its rating. The 200V figure is the series voltage limit, not a voltage you can use at this value.

How do I fit a 1206 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 3.1 mm body before you solder, use a fine tip and a small amount of solder, and do not overheat the part.

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.
