Detailed characteristics and datasheet highlights of the CFR200J-220R carbon film resistor.
Tips for choosing, handling, and using the CFR200J-220R in your builds.
Availability and lead time details for South African buyers at Communica.
The CFR200J-220R is a 220-ohm, 2-watt carbon film resistor, widely used in analog and digital circuits across South Africa. Makers, engineering students, and technicians often choose it for signal limiting, voltage dividers, LED protection, and power supply applications, owing to its robust power rating and reliable construction.
| Feature | CFR200J-220R Spec |
|---|---|
| Resistance | 220 Ohm (ohms) |
| Power Rating | 2 W (watts) @ +70 degreesC |
| Tolerance | 5% (J) |
| Maximum Working Voltage | 350 V |
| Temperature Range | -55 degreesC to +155 degreesC |
| Body Size (approx.) | L: 15 mm, D: 5.5 mm |
| Leads | Axial, tinned copper |
| Coating | Flame retardant epoxy |
This resistor is made with a carbon film deposited on a ceramic rod, trimmed to value, then spiral-cut for tunable resistance and coated for reliability. The carbon film structure gives moderate noise performance and long-term stability within general-purpose circuits.
Common applications in South Africa include:
For student labs and tertiary practicals, the rugged 2W power rating lets you safely prototype with higher input voltages or pulses than smaller 1/4 or 1/2 watt resistors. This makes it a go-to choice for engineering courses and project kits stocked via Communica's education-focused offering.
Suppose you want to drive a red LED (forward voltage ~2V, recommended current 10 mA) from a 5V GPIO pin. Using Ohm's Law (V = IR):
GPIO O---[220Ohm]---|>|---GND
LED
