Applications
The 0805L075SLYR is commonly used to protect USB ports, battery charger circuits, and portable device power inputs against overcurrent faults caused by cable shorts or faulty peripherals. Its automatic reset behavior makes it ideal in consumer electronics where user-accessible fuse replacement is impractical, such as tablets, laptops, and IoT hub USB interfaces. It is also suitable for protecting telecom line card inputs and low-voltage DC distribution circuits up to 750mA from sustained overloads.

Frequently Asked Questions
What is the hold current and trip current of the 0805L075SLYR PTC fuse?
The 0805L075SLYR has a 750mA hold current, meaning it passes this current indefinitely without tripping under normal operation. The trip current is typically 1.5A, at which point the PTC polymer resistance increases dramatically to limit current, protecting the connected circuit from sustained overloads while allowing automatic recovery once the fault clears.
How does the 0805L075SLYR resettable fuse recover after an overcurrent event?
The 0805L075SLYR uses a polymeric PTC (positive temperature coefficient) element that transitions to high resistance when overheated by excess current above 750mA hold rating. Once the overcurrent source is removed and the device cools below its transition temperature, the polymer returns to low resistance within a few seconds, automatically restoring protection without any manual intervention or replacement.
In which circuit protection applications is the 0805L075SLYR most commonly used?
The 0805L075SLYR is most commonly applied on USB 2.0 VBUS power lines rated at 500mA, charging circuits for Li-ion batteries, and low-voltage DC distribution rails up to 750mA. Its self-resetting characteristic is particularly valuable in consumer electronics where users cannot access internal fuses, and in industrial IoT devices requiring automatic fault recovery without field service.
What is the PCB footprint and height of the 0805L075SLYR and why does it matter for assembly?
The 0805L075SLYR occupies a standard 0805 SMD footprint of 2.2mm x 1.5mm with a height of just 0.75mm, enabling high-density PCB layouts with standard 0805 stencil paste and reflow assembly processes. The low profile is essential for thin devices such as smart cards, wearables, and compact IoT modules where component height is constrained to under 1mm.
