Resettable fuses - Fuzetec

How do PPTC Resettable fuses work?

The resettable fuses of Fuzetec™ are designed and made of patented novel PPTC material in thin chip form where conductive particles are dispersed in a polymer that has a crystalline structure.

At normal operating conditions there are numerous chains forming conductive paths throughout the PPTC material. Under fault conditions (Tripped State), excessive current flows through the PPTC device and the PPTC material heats up.

This makes the polymer matrix’s morphology change from crystalline to amorphous. Under these conditions the conductive particles move apart from each other, most of them no longer conduct current and the resistance of the device increases sharply.

Upon fault current being removed, the resettable fuse is reset and allows the current to flow through the circuit again.
 

Bluetooth® 5.2 Combi Module – LM833 - LM Technologies

This versatile module combines WiFi and Bluetooth® radios, plus an ARM Cortex-M3 microcontroller.

The LM833 utilises a powerful Infineon chipset which enables the LM833 HCI Module to be compatible with the latest Android / Linux platforms. It’s SMT side and bottom pads allow for easy manufacture and placement within your product.

The LM833 module incorporates an intelligent coexistences mechanism for Wi-Fi 802.11 b/g/n via SDIO and Dual Mode Bluetooth® v5.2 via UART. This is ideal for significantly minimizing the BoM cost and PCB space. Available with IPEX connector or with integrated PCB antenna.

Supports Bluetooth adaptive power management mechanism 19mm x 12mm x 2mm.
