IoT Components AVX Internet of Things (IoT) Components meet the requirements of IoT microcontroller (MCU) chips. These IoT MCU chips require an input voltage filtering / decoupling network and an output impedance matching network for the RF antenna. The antenna usually communicates using BLUETOOTH® LE, ZigBee, ANT, or other wireless network protocol. AVX provides passive components are suitable for use in all required networks of operation for IoT devices.
