Learn how and where to use CHR1206-1 100 ohm resistors in your circuits. Includes specs, best practices, calculations, and South African sourcing advice.
Understand ratings and benefits of 1206 100Ohm SMD resistors.
Get practical tips to calculate power, place, and solder these resistors.
Discover where to find CHR1206-1 resistors for engineering and education in South Africa.
The CHR1206-1 100Ohm resistor is a surface-mount (SMD) component with a 1206 metric footprint. Widely used for signal conditioning, pull-up/down tasks, and current limiting in modern electronics, it offers reliable performance for both prototyping and soldered production PCBs. The '1206' refers to 3.2mm x 1.6mm size, making it a standard for engineers designing compact and automated assemblies.
| Parameter | CHR1206-1 100Ohm Typical Value | Notes |
|---|---|---|
| Resistance (R) | 100Ohm 1% | Suitable for precision signal uses |
| Package Size | 1206 (3216 Metric) | Industry SMD standard |
| Max Power Rating | 0.25W (250mW) | Check for thermal safety |
| Tolerance | 1% (E24 series) | Tighter than general 5% |
| Operating Temperature | -55 degreesC to +155 degreesC | Typical, check datasheet |
CHR1206-1 resistors suit a wide range of electronics, including:
Communica supplies 100Ohm 1206 resistors under several brands. Always match your design files or BOM with stock codes for minimising project delays.
Consider driving a standard LED (forward voltage 2V) from a 5V microcontroller pin. What current will the CHR1206-1 100Ohm provide, and is the resistor operating within its power rating?
This is well below the CHR1206-1 0.25W rating, allowing safe operation in typical switching or status indicator scenarios.
The SMD 1206 footprint is forgiving for hand soldering with a fine-tip iron and 0.5mm solder. Secure one pad with tweezers, tack solder one end, then reflow the other side. For mass production or student batch runs, use a hot air station or reflow oven.
| Problem | Diagnosis Tips | Fix |
|---|---|---|
| No current through load | Resistor open/poor solder joint; test with DMM resistance | Re-solder, verify track continuity |
| Excessive heating | Over-power due to under-sized resistor | Change to higher wattage, adjust circuit values |
| Wrong resistance measured | Possible wrong part fitted or parallel paths | Check part numbering, layout, and DMM on bare PCB |
