Reliable local supply of communication ICs
Find the communication ICs you need in Johannesburg without weeks-long lead times. Communica keeps common RF, wired-comm and interface semiconductors in stock so technicians, students and engineers can prototype, repair or deploy quickly. Shop Now or Check Stock in Samrand to confirm same-day branch pickup from our Pretoria/Samrand hub.
What we stock and why it matters
We focus on parts that matter for real projects: RF transceivers, PLLs, modulators/demodulators, UART/SPI/I2C interface ICs, CAN/LIN controllers, and SiP front-ends for LoRa and BLE. Having these locally stocked reduces risk for student labs and field technicians - fewer delayed builds and predictable VAT invoices for campus procurement.
Specification callouts you should check
When selecting a communication IC, prioritise signal standard, data rate, operating voltage, package and temperature range. Practical examples below show common selection trade-offs for Johannesburg deployments.
| Type | Typical use | Key spec |
|---|---|---|
| BLE/Thread SoC | Wearables, short-range IoT | Data rate, RF output power, power modes |
| LoRa/LPWAN transceiver | Long-range sensors | Frequency band (EU/AS923), sensitivity, regulator support |
| CAN controller | Automotive/industrial networks | Bus speed, timestamping, transceiver compatibility |
Compatibility & accessory bundles
Many communication ICs need external passives, crystals and antenna matching networks. Check our accessory bundles for evaluation: breakout boards, reference crystals and matched antennas save time during prototyping. Compare Specs to pick parts that match your MCU voltage and board layout constraints.
