Explore the CFR200J 10K resistor: full datasheet, specifications, tolerances, application tips, and buying guidance for South African electronics projects-available at Communica.
Get detailed ratings, dimensions, and tolerance for the CFR200J 10K carbon film resistor.
See where to use this resistor and how to choose for SA projects.
Find real-world stock and advice for South African hobbyists and engineers.
The CFR200J 10K is a widely used carbon film resistor valued for reliability, stable performance, and practicality within educational, hobby, and industrial South African electronics. Its 10,000-ohm nominal resistance and standard 200 mW (1/5 W) power rating suit analog, digital, and signal-limiting circuits commonly found in local labs, schools, and service benches.
This guide details the official datasheet information for the CFR200J 10K, practical selection tips for South African conditions, and local notes on brand options, stock access, and usage scenarios.
| Parameter | CFR200J 10K Typical |
|---|---|
| Resistance | 10,000 Ohm (10 kOhm) |
| Tolerance | 5% |
| Rated Power | 0.2 W (200 mW) at 70 degreesC |
| Max Working Voltage | 250 V |
| Max Overload Voltage | 500 V |
| Body Size (Dia x L) | Approx. 2.2 x 6.3 mm |
| Lead Diameter | 0.50-0.55 mm |
| Temperature Range | -55 degreesC to +155 degreesC |
CFR200J 10K (carbon film) is preferred when cost, ease of availability, and non-critical noise are priorities. For precision or lower temperature coefficient, metal film equivalents (MFR series) can be sourced from Communica's broader selection.
On physical inspection, expect the resistor to display the following markings:
Use a standard multimeter for on-bench verification, especially when prototyping frequently with local E12 kits.
Always ensure the resistor can dissipate expected power safely. For breadboard logic circuits, power dissipation is typically under 0.05 W, well within the CFR200J 10K's 0.2 W rating. For applications with prolonged high voltage, verify the max working voltage (250 V typical).
Use Ohm's Law:
P = V2 / R or P = I2 x R
| Scenario | Applied Voltage (V) | Resulting Power (W) |
|---|---|---|
| 3.3V microcontroller pull-up | 3.3V | ~1.1 mW |
| 12V LED series current limit | 12V | ~14.4 mW |
Both cases are well under the 200 mW max load, offering a good margin under typical environmental conditions found in SA education labs or garages.
