With prices tailored for education, bulk, and industry needs, you get genuine value and real product choice-no need to risk overseas shipping costs or long delays.
Popular Fuse Types and Applications
| Type | Typical Use | Common Ratings | Local Stock Notes |
|---|---|---|---|
| Glass Cartridge (5x20mm, 6.3x32mm) | General electronics, power boards, battery packs | 250mA-10A | High availability, sold as singles or value packs |
| Ceramic Cartridge | High-blow and thermal protection for power supplies | 500mA-32A | Stocked for robust applications |
| Blade/Mini Blade | Automotive, robotics, DC systems | 2A-30A | Specialist and standard sizes |
| Resettable Polyfuse (PTC) | PCB protection for microcontrollers, USB | 100mA-6A | Popular for makers and repairs |
Fuse Value - What to Check for on a Budget
- Verify voltage (V) and current (A) ratings for your application-undersizing leads to nuisance trips, oversizing can reduce protection.
- Choose between fast-blow (quick to react, for delicate circuits) and slow-blow (for tolerance to inrush or startup surges).
- Bulk packs often provide the most affordable price per fuse for labs or busy service benches.

Specification Tips & Local Buying Advice
- For Arduino, Raspberry Pi, and low-voltage prototyping, 5x20mm glass cartridge fuses (e.g. 500mA, 1A, 2A) offer ample protection and are widely available affordably in Cape Town.
- Mini blade fuses fit automotive and solar applications and are simple to source in packs at a lower unit cost.
- Resettable PTC fuses (polyfuses) suit USB, motor drive or power control projects-ideal if you want self-resetting protection without needing to replace blown fuses repeatedly.
Fuse Sizing Calculation
To size your fuse, a basic rule is to multiply your normal operating current by 1.5 (to allow some margin) without exceeding the maximum cable or device rating. For example:
| Application | Normal Current (A) | Fuse Calculation | Suggested Fuse |
|---|---|---|---|
| LED Project (breadboard) | 0.08A | 0.08A x 1.5 ~ 0.12A | Glass Cartridge 250mA |
| Arduino Uno Board | 0.5A | 0.5A x 1.5 = 0.75A | Glass Fast-blow 1A |
| Small DC Motor (robotic) | 0.9A (stall) | 0.9A x 1.5 = 1.35A | Blade Fuse 1.5A or 2A |
