The CHR1206-1 220R resistor is a popular surface-mount device (SMD), widely used for current-limiting, biasing, pull-up/pull-down, and signal-conditioning in both student labs and professional assemblies. It offers a resistance value of 220Ohm and is presented in a 1206 metric package-making it easy to handle for rework and reliable for automated assembly.
Selecting the right 220Ohm SMD resistor involves reviewing rated power, voltage, tolerance, and temperature stability. Datasheets-often provided by brands such as Yageo or Vishay-detail each parameter so makers and engineers match components to their needs. Communica stocks a deep range of 1206 SMD resistors for local purchase or branch pickup.
| Parameter | Specification | Notes |
|---|---|---|
| Resistance | 220Ohm (220R) | Standard marking: "221" (E24 series) |
| Case Size | 1206 (3.2 x 1.6 mm) | Metric: 3216; Imperial: 1206 |
| Power Rating | 0.25W (1/4 Watt) | Check datasheet for derating at >70 degreesC |
| Tolerance | 1% (F) or 5% (J) | Common options: confirm code |
| Temperature Coefficient | 100ppm/ degreesC typical | Lower ppm improves stability |
| Maximum Working Voltage | 200V (typical) | See datasheet; actual value varies |
| Packaging | Tape & Reel, Cut-tape | Reel size varies: 1k-5k pcs |
"CHR1206-1-220R" breaks down as follows:
Datasheets specify maximum ratings, temperature curves, recommended soldering profiles, and packaging. Always use these to confirm thermal and voltage margins, especially when designing for industry or tertiary education labs where reliability is critical.
| Scenario | Calculation | Result |
|---|---|---|
| 5V across 220Ohm | P = (5V)2 / 220Ohm = 0.114W | Safe (well within 0.25W) |
| 12V across 220Ohm | P = 144 / 220 ~ 0.655W | Exceeds-use higher-wattage or series |
| Feature | Typical Value |
|---|---|
| Resistance | 220Ohm |
| Package | 1206 SMD |
| Power | 0.25W (1/4W) |
| Tolerance | 1% or 5% |
| Temp. Coefficient | 100ppm/ degreesC |
