Introduction

The Bel Fuse 0ZLK Low Rho PTC Fuses are advanced circuit protection components designed to safeguard electronic circuits from overcurrent conditions. With their compact size and efficient performance, these fuses are ideal for modern electronic devices that demand reliability and space-saving solutions.

Part Description

The 0ZLK Low Rho PTC Fuses from Bel Fuse are surface-mount devices (SMD) featuring a small 0805 chip size. They are designed to operate at a maximum voltage of 6V DC and can handle up to 100A of current. These fuses stand out for their faster trip time and lower resistance compared to standard SMD fuses, making them highly responsive to overcurrent events. The hold current ranges from 750mA to 3A, and they function effectively within a temperature range of -40°C to +85°C. Additionally, these fuses comply with the 2011/65/EU and 2015/863 RoHS directives, ensuring they meet environmental and safety standards.
