The MFR25F 4k7 or 4.7kOhm 1/4W resistor is a staple in South African electronics projects, valued for its reliability and versatility in analog and digital circuits. Used widely by hobbyists, students, and engineers, these resistors are essential for tasks like pull-up/pull-down networks, voltage dividers, timing circuits, and input protection. The key to a trouble-free project is sourcing genuine, specification-compliant components from a trusted distributor with local support.
The "MFR25F" part code refers to a metal film resistor series, commonly 1/4 watt (0.25W) with a 1% tolerance. The "4k7" (4700 ohms) value makes it suitable for current limiting, biasing, and signal control. Metal film types are prized for low noise, stable tolerance, and improved temperature stability compared to carbon film types.
| Feature | Spec |
|---|---|
| Resistance | 4.7kOhm (4k7), E24 series |
| Tolerance | 1% (F) |
| Power Rating | 0.25W (1/4W) |
| Type | Axial (through-hole), metal film |
| Typical Applications | Signal conditioning, pull-up/pull-down, voltage divider |
Procurement teams, students, and hobbyists often need reliable, traceable sources in South Africa to avoid sub-par, off-spec components. Look for suppliers that:
A critical question is: How much current and power can the resistor handle in your circuit? The MFR25F 1/4W is suitable for most signal-level and LED-limiting applications at 5V or 3.3V logic.
This demonstrates the 4k7 resistor is an excellent choice for such indicator or signal roles, both in student labs and low-power applications.
| Parameter | Recommended Range | Notes |
|---|---|---|
| Resistance | 4.7kOhm | Colour code: yellow-purple-red-gold |
| Tolerance | 1% | Blue or beige body (metal film), low drift |
| Power | 0.25W (1/4W) | Derate above 70 degreesC ambient in high-heat enclosures |
