Explore technical specs, tolerance, power, and uses of the CFR25J 8K2 resistor. Ideal for South African students and engineers. Sourcing tips from Communica.
CFR25J 8K2 offers reliable 8,200Ohm with 5% tolerance for most electronics circuits.
Durable construction, suitable for signals, bias circuits, and breadboarding.
Popular for education, prototyping, hobby, and repairs-easy to source from local branches.
The CFR25J 8K2 is a carbon film, through-hole resistor providing a precision of 8.2 kOhm (kilo Ohms) resistance. With a quarter-watt (0.25W) power rating, this resistor is a staple component for electronics designs, commonly utilized for voltage division, signal conditioning, filtering, and current limiting across education, hobbyist, and professional South African environments.
'CFR25J' designates the carbon film series, "25" the 0.25 watt rating, and "J" signifies the 5% tolerance. "8K2" is an engineering shorthand denoting 8,200 Ohms.
| Parameter | Value | Comment |
|---|---|---|
| Resistance | 8,200 Ohm (8K2) | E24 standard value |
| Tolerance | 5% (J) | Typical for carbon film |
| Power Rating | 0.25 W (1/4 W) | Max continuous |
| Max Working Voltage | 250 V DC | Per datasheet |
| Temperature Range | -55 degreesC to +155 degreesC | Derate above 70 degreesC |
| Body Size | Approx. 6.3mm x 2.3mm | Not including leads |
| Lead Spacing | ~5mm | Fits standard breadboards |
When choosing a CFR25J 8K2 resistor for your project in South Africa, keep in mind both availability and the following technical points:
Suppose you want to limit current for a red LED (forward voltage = 2V) using a 5V microcontroller supply. Desired LED current is 1 mA for a low-brightness indicator circuit.
Thus, the CFR25J 8K2 is suitable-no heat or tolerance problems in this scenario.
