Learn to identify faults in 10K CFR200J resistors: symptoms, testing steps, SA-part sourcing, and replacement guides from Communica's extensive components range.
Spot overheating, open circuits, and incorrect resistance in CFR200J 10K resistors.
Use a multimeter to measure, compare, and confirm resistor function on the bench.
Find compatible 10K carbon film resistors from trusted brands in SA stock.
The CFR200J 10K is a 10-kiloohm, 0.25W carbon film resistor, widely used in educational electronics kits, industrial control boards, and repairs across South Africa. The part code typically denotes: CFR (carbon film resistor), 200 (0.25W or 250mW), J (5% tolerance), and 10K (10,000 ohms). Familiarity with this standard code assists students, makers, and technicians in identifying direct replacements and understanding circuit values.
| Property | Value |
|---|---|
| Resistance | 10 Ω kΩ (10,000 Ohm) |
| Tolerance | ±5% (J-grade) |
| Power Rating | 0.25W (250mW) |
| Body Type | Carbon film, axial leaded |
In South African contexts, CFR200J 10K resistors are stocked by brands like Royal Ohm, KOA Speer, and Uniohm, with immediate collection available at Communica's Samrand and regional branches. Lead times are minimal for standard carbon film values.
If your circuit experiences voltage irregularities, unpredictable output, or won't power up after a spike or overload event, the CFR200J 10K resistor may be at fault-particularly if it's located in biasing, pull-up, or feedback positions. Rapid troubleshooting helps avoid deeper board-level damage.
A student's power supply stops regulating. On inspection, the bias resistor - marked as CFR200J 10K - is charred and reads >50KΩ on a DMM. Replacing with a same-value carbon film resistor sourced at Communica restores normal voltage output.
| Nominal | −5% | +5% |
|---|---|---|
| 10 000Ω | 9 500Ω | 10 500Ω |
If your measurement is outside this range, the resistor is likely faulty and should be replaced with a new CFR200J 10K or equivalent rated part.
---[10K]--- | | Input Output
The typical axial format allows straightforward through-hole replacement. Observe orientation for best soldering access, though polarity does not apply to resistors.
