Discover how to choose and use CHR0603-1 100Ohm SMD resistors for electronics projects in South Africa: specs, selection, application examples, and sourcing tips from Communica.
Understand the ratings and coding of CHR0603-1 100Ohm SMD resistors.
How to choose, solder, and troubleshoot 0603 SMD resistors locally.
Find stock, lead times, and SA favourites at Communica branches.
The CHR0603-1 100Ohm resistor is a compact, surface-mount, chip resistor popular in South African electronics for its precise 100-ohm value and space-saving size. The 0603 (metric 1608) SMD package measures just 1.6mm x 0.8mm, making it ideal for high-density PCBs in IoT, embedded, and educational projects. These resistors are used for current limiting, pull-up/down, voltage dividers, filtering, and signal conditioning-critical in circuit stability and reliability for both students and professional engineers.
| Parameter | Typical Value | Notes |
|---|---|---|
| Resistance | 100Ohm 1% (E24 series) | Standard tolerance for general use |
| Package | SMD 0603 (1608M) | 1.6mm x 0.8mm footprint |
| Power Rating | 0.1W (100mW) | Verify if higher dissipation is needed |
| Max Working Voltage | 50V (typical) | Check datasheet for exact value |
| Temperature Coefficient | 200ppm/ degreesC | Affects high-precision or high-temp use |
| Code Marking | 101 | Standard 3-digit code for 100Ohm |
To use a 100-ohm resistor safely, check power and voltage drop:
+-----[101]-----+ | | Vdd Input/Out
In SMD layouts, ensure pad size matches 0603-typically 0.8mm wide with 0.5mm spacing to suit reflow soldering.
