View current pricing, bulk discounts, and near-instant local availability for CFR200J 8R2 2W carbon film resistors. Technical specs and procurement tips from Communica.
South African branches and online store for immediate CFR200J 8R2 resistor supply.
Competitive volume pricing and VAT invoicing for education, industry, and prototyping needs.
Core features, ratings, and compatible alternatives fully explained.
The CFR200J 8R2 is a popular carbon film resistor, commonly used for general electronics, prototyping, and circuit protection tasks. With a nominal value of 8.2 ohms and a 2W power rating, it is favoured by South African hobbyists, tertiary labs, and industry for both breadboard and production applications. Local availability and clear specifications make it a go-to for both students and professionals seeking reliable, price-efficient solutions.
| Parameter | Value / Description |
|---|---|
| Type | Carbon Film Fixed Resistor |
| Nominal Resistance | 8.2 Ohm |
| Tolerance | 5% (J code) |
| Power Rating | 2W |
| Body Size (Approx.) | 6.4 x 19.0 mm |
| Lead Spacing | About 22 mm |
| Temperature Coefficient | Typically 350 ppm/ degreesC |
CFR200J 8R2 resistors are offered in singles for bench work as well as in reels or bags for manufacturing runs. Pricing is quantity-dependent, and bulk orders often attract significant discounts. As of Q2 2024, single-unit pricing in South Africa typically ranges from ZAR 1.20-2.50 per piece, with reductions for orders of 100 and 1,000 units. Please note that prices may vary with exchange rates and global supply chain adjustments.
Local distributors such as Communica update live inventory via their website. Branch pickup means urgent prototyping or repair work can be supported with minimal downtime, and direct account management is available for high-volume or repeat business customers.
Alternative values and packages (e.g., 1W resistors, flameproof or metal film variants) are also locally stocked for cases where tighter tolerance or different environmental robustness is needed. Search the Resistors category to compare specifications and brands suited for your project.
Suppose you need to limit current to an indicator LED at 12V supply (Vsupply), using the CFR200J 8R2 (R = 8.2 Ohm). With a forward voltage of 2V for the LED (VF):
I = (Vsupply - VF) / R = (12V - 2V) / 8.2Ohm ~ 1.22A
At this current, power dissipation in the resistor is:
P = I2 x R ~ (1.22A)2 x 8.2Ohm ~ 12.2W
This substantially exceeds the 2W rating. Thus, always select your resistor so its dissipated power is below the specified maximum, with 25-50% margin advised for reliability, especially in the South African climate where ambient temperature can be elevated in non-airconditioned spaces.
