Get CFR50J 100KOhm resistors from Communica's national warehouse for reliable, quick supply.
Widely used for labs, repairs, and educational kits in South Africa.
Order online, check stock levels, and choose branch pickup or delivery.
The CFR50J 100K resistor is a popular 100,000 ohm (100KOhm) carbon film resistor, rated at 0.5W (1/2 watt), and suitable for a wide range of South African electronic builds. Used by students, makers, and professionals, these resistors are frequently specified for voltage dividers, bias networks, signal conditioning, and as general-purpose drop-in components for breadboarding, repairs, or circuit prototyping.
Communica stocks tens of thousands of CFR series resistors with robust local inventory management, VAT-compliant invoicing, and in-branch collection from Samrand, Pretoria CBD, and Cape Town. Whether you need a few units for a university project or a bulk reel for production, reliable supply is a click away.
The code CFR50J-100K tells you the key specs:
| Parameter | Value | Typical Use |
|---|---|---|
| Resistance | 100KOhm | Voltage Divider, Pull-Up/Down, Filters |
| Power Rating | 0.5W (1/2W) | General Purpose, Analogue Loads |
| Tolerance | 5% (J) | Student, Maker Builds, Non-critical |
| Technology | Carbon Film | Breadboard, Solder Prototyping |
For typical South African projects, the CFR50J 100K suits:
Communica's warehouse model means you can check live stock status online before ordering. Bulk pack sizes are available (e.g. 10s or 100s) for education and workshop use. If you need guaranteed availability for orders over 1,000 units, enquire for procurement/invoice options with confirmed ZAR pricing and scheduled branch collection. Trusted brands are in stock, including Royal Ohm, Uniohm, Sussex, and others.
| Attribute | CFR50J Series | Other Types (for comparison) |
|---|---|---|
| Rated Voltage | Up to 350VDC | Metal Film: Up to 500VDC |
| Lead Pitch | ~9mm | Varies by type |
| Temperature Range | -55 degreesC to +155 degreesC | Metal Film: Better stability |
For most breadboard and repair applications, CFR50J 100KOhm strikes the right balance of price, availability, and durability under normal South African temperature ranges and lab environments.
Use the power formula to check if a 0.5W (1/2W) resistor is suitable:
If you place a 100KOhm resistor across 50V:
It's safe for most logic and analog circuits. For higher voltage or current, select a higher wattage (1W or 2W series).
Visit the All Products or Circuit Protection & Passive Components categories on the Communica website. Filter by resistance value (100KOhm), power rating (1/2W), and brand. Select the desired pack size, check the Samrand, Pretoria, or Cape Town branch stock availability, and order online for VAT invoicing or collection.
