Learn about CHR1206-1 220Ohm resistors: SMD sizing, ratings, how to choose the right spec, troubleshooting hints, and local buying advice from Communica.
Understand the CHR1206-1 220Ohm resistor's key ratings for safe, compact circuit design.
Get practical tips for choosing, calculating, and sourcing the right SMD resistor for your build.
Find reliable supply, quick branch pickup, and VAT invoicing for CHR1206 resistors in South Africa.
The CHR1206-1 220R resistor is a surface-mount device (SMD) with a resistance of 220 ohms, designed for modern compact electronic assemblies. The "1206" refers to its package size-measuring 3.2mm x 1.6mm-making it a popular choice for prototyping and production across South African projects. Its use spans microcontroller pull-ups, LED current limiting, sensor interfaces, and power regulation.
Key features of the CHR1206-1 series include stable resistance values, good power handling for size, and reliable solderability on standard PCBs. Understanding their parameters helps makers, students, and technicians ensure longevity and safe operation in dense layouts.
| Parameter | Typical Value (CHR1206-1 220R) | SA Buying Context |
|---|---|---|
| Resistance | 220Ohm (1% or 5%) | Common for LEDs & signal lines |
| Package Size | 1206 (3.2mm x 1.6mm) | Compatible with local PCB houses |
| Power Rating | 0.25W (250mW) | Suited for low-power circuits |
| Tolerance | 1% (E96), 5% (E24) | E24 and E96 are widely available |
| Temperature Coefficient | 100ppm/ degreesC typical | Sufficient for most hobby/edu use |
Choosing a suitable 220Ohm 1206 resistor goes beyond value alone. You must match the part's specs to your application's voltage, expected current, physical footprint, and environment.
Suppose you run a 5V supply, a standard red LED (forward voltage ~2V), and want 220Ohm as your current limiter.
This is well within the 1206-1's 0.25W capability-perfect for microcontroller outputs and hobby lighting. Extended use in higher ambient temperatures (common in SA workshops) may require derating the resistor to avoid exceeding safe limits.
