The MFR12F 24K resistor is a precision metal film resistor with a resistance value of 24 kilo-ohms (24,000 Ohm), commonly adopted in South African academic, R&D, and repair settings. Its compact axial form factor, stable temperature coefficient, and tight tolerance make it a staple for analog, signal processing, and voltage divider circuits. Recognising its specifications and suitable applications helps ensure reliable and predictable circuit operation.
| Parameter | Value (Nominal) | Notes |
|---|---|---|
| Resistance | 24 kOhm (24,000 Ohm) | Marked as '24K0'; E24 or E96 series |
| Tolerance | 1% (F) | Marked 'F' for precision e.g. brown-black-orange-red-brown |
| Power Rating | 0.5W (1/2 Watt) | For continuous load at 70 degreesC ambient |
| Temperature Coefficient | 100 ppm/ degreesC | Stable over industrial range |
| Max Working Voltage | 350V (typical) | Check datasheet for exact rating |
| Body Size (approx.) | 3.2 mm x 9 mm | Axial, fits standard PCB pads |
A typical MFR12F 24K resistor uses five colour bands for 1% tolerance. Colour code: red (2), yellow (4), orange (multiplier 1,000), red (significant figures), brown (1% tolerance). Always check the manufacturer's marking or use a multimeter for confirmation when prototyping or repairing mixed-value circuits.
These resistors excel in:
In South African tertiary labs, the MFR12F 24K is popular in electronics practicals for biasing and calibration-balancing high enough resistance to reduce loading with low enough value to mitigate noise pickup in longer breadboard runs.
| Parameter | MFR12F 24K (Metal Film) | Carbon Film 24K |
|---|---|---|
| Tolerance | 1% | 5%-10% |
| Temp. Coefficient | 100 ppm/ degreesC | 300 ppm/ degreesC |
| Noise | Low | Higher |
| Typical Use | Precision/analog | General/low-cost |
While MFR12F is a common generic code, reputable manufacturers such as Yageo, Royal Ohm, Uniohm, and others are widely distributed in South Africa. Always verify datasheets for exact voltage, tolerance, and temperature ratings before finalising selection in professional designs.
