Why capacitor pricing matters for your build
Choosing capacitors isn't just about finding the lowest price - it's about matching value, reliability and availability so your prototype or production run doesn't stall. At Communica we stock film, ceramic (MLCC), electrolytic (aluminium/polymer) and tantalum styles across common values and voltages, letting South African makers, students and technicians compare real costs and delivery options locally.
Local advantages that affect price and lead time
Buying locally reduces lead time, import VAT surprises and freight overheads. Collect from our Samrand head office or visit branches in Pretoria and Cape Town to avoid courier delays. For institutions and procurement teams we provide VAT invoices and account quoting - factors that change effective project cost even when catalogue prices look similar.
Quick price comparison table
Typical retail and small-bulk price bands you will see in our ranges (indicative - check live stock):
| Type | Typical Values | Price Band (ZAR each) | Common Use |
|---|---|---|---|
| MLCC (ceramic) | 1pF-10uF | R0.50-R20 | Decoupling, HF filtering |
| Film (polyester/PP) | 10nF-10uF | R5-R120 | Timing, audio, mains suppression |
| Aluminium electrolytic | 1uF-10,000uF | R8-R300 | Bulk storage, power rails |
| Polymer electrolytic | 4.7uF-4700uF | R25-R450 | Low ESR power supplies |
Specification callouts to watch (affects price)
- Voltage rating - overspec by 20-50% for electrolytics in switching supplies.
- ESR and ripple current - key for power supply caps; lower ESR usually costs more.
- Tolerance and temperature coefficient - MLCC class II vs class I pricing differs significantly.
- Package size and lead style - SMD vs radial leads change both unit cost and assembly expense.
