The CFR25J-1M0 is a 1 megaohm (1,000,000 ) carbon film resistor commonly used for signal conditioning, pull-ups, measurement circuits, and voltage dividers. Popular for its affordability and reliability, this resistor is part of the CFR series, typically rated at 0.25W (1/4W), making it suitable for breadboarding, prototyping, educational kits, and repair work in a South African context.
Selecting the right resistor depends on correct value, power rating, and physical size-particularly for students, technicians, and engineers sourcing locally. The datasheet is the definitive source for voltage rating, tolerance, and environmental specs, ensuring fit-for-purpose use in both academic and industrial builds.
| Parameter | Value | Notes (SA context) |
|---|---|---|
| Resistance | 1 M (1,000,000 ) | Standard E24/E96 value - often used in audio, analog & logic pulls |
| Tolerance | 5% | Marked with gold band |
| Power Rating | 0.25W (1/4W) | Suits most breadboard & PCB use |
| Body Size | ~6.3mm x 2.3mm | Standard through-hole form |
| Max Working Voltage | 250V | Exceeding this risks breakdown |
| Temperature Coefficient | 350ppm/ degreesC | Relevant for precision circuits |
The full official datasheet for the CFR25J-1M0 can be found directly from the manufacturer's or principal distributor's website. This document provides:
When specifying the CFR25J-1M0, consider these local factors:
For basic circuit design, check that your resistor selection remains within its safe power limit. Use Ohm's Law to confirm:
Example: In a 5V pull-up circuit using a CFR25J-1M0:
This makes it suitable for low-power digital and analog projects common in education and prototyping across South Africa.
