ESD components, inductors, PMICs, and capacitors play crucial roles in the IoT industry.

ESD (electrostatic discharge) components are used to protect sensitive electronic devices from damage caused by electrostatic discharge events. In IoT devices, ESD components are commonly found in input/output ports, such as USB and HDMI ports, as well as in communication modules such as Wi-Fi and Bluetooth.

Inductors are used to filter noise and smooth out power supply ripple in IoT devices. They are commonly found in power management circuits, where they help regulate the flow of current to the device.

PMICs (power management integrated circuits) are essential components for efficient power management in IoT devices. They are used to control and regulate the power supply to the device, ensuring that it runs smoothly and efficiently.

Capacitors are used in IoT devices for a variety of purposes, including filtering noise, regulating voltage, and storing energy. They can be found in power management circuits, communication modules, and other areas of the device where electrical energy needs to be controlled or stored.

Overall, ESD components, inductors, PMICs, and capacitors are critical components for the proper functioning and protection of IoT devices. Without these components, the reliability and performance of IoT devices would be greatly diminished.
