Explore detailed reviews and hands-on user experiences of the CFR25J-150R resistor. Learn specs, best applications, and local stocking options at Communica South Africa.
Consistent performance makes the CFR25J-150R popular in schools, labs, and test builds.
Rated 150Ohm, 0.25W, 5% tolerance-well-suited for standard circuits and breadboarding.
Widely stocked at Communica branches, with VAT invoices and student-friendly bulk packs.
The CFR25J-150R is a carbon film fixed resistor rated at 150 ohms (Ohm), 0.25 watt (W) power dissipation, and 5% tolerance (J). It's a staple in electronics education, repair benches, and rapid prototyping across South Africa. Its affordability, availability, and solid reliability make it popular among university students, hobbyists, and production engineers alike.
This resistor's core use is in signal conditioning, pull-up/pull-down applications, LED current limiting, and timing circuits. Whether you're building your first breadboard project or specifying replacements for repairs, understanding hands-on user experiences provides valuable context for selecting passive components.
| Attribute | Value |
|---|---|
| Resistance | 150 Ohm |
| Power Rating | 0.25 W (1/4 W) |
| Tolerance | 5% (J) |
| Body Type | Axial, Leaded |
| Technology | Carbon Film |
Choosing the CFR25J-150R comes down to these factors:
| Model | Type | Power (W) | Tolerance | Typical Applications |
|---|---|---|---|---|
| CFR25J-150R | Carbon Film | 0.25 | 5% | Education, LED limiting |
| MFR25S-150R | Metal Film | 0.25 | 1% | Precision, analog |
| CF1/4-150R | Carbon Film | 0.25 | 5% | General use |
Most South African circuit building workshops recommend the CFR25J series for basic builds due to its balance of price, quantity options, and availability at local distributors.
A typical use for the CFR25J-150R is in series with 5V microcontroller GPIO driving an LED. Calculation example:
Using Ohm's law: R = (V - Vf) / I = (5V - 2V) / 0.02A = 150Ohm. Power dissipated: P = I2 x R = 0.022 x 150 = 0.06W, well within the 0.25W rating. This margin is typical of SA STEM classes and student designs.
Repeated user input from South African makers indicates that the CFR25J-150R:
