Key Features
- Fast-blow characteristic for rapid response to short-circuit events, protecting sensitive components
- 500mA rated current in a standard 1206 SMD package for automated PCB assembly
- Ultra-low body height of 0.6mm suitable for thin form-factor electronic designs
- RoHS-compliant lead-free construction meeting modern environmental standards
Applications
The SF-1206F500-2 is used as a primary overcurrent protection element on USB power lines, Li-ion battery pack outputs, and 5V supply rails in consumer electronics and IoT devices. Its fast-blow action ensures immediate circuit interruption during short-circuit conditions, preventing damage to downstream components rated below 500mA. The 1206 chip format enables automated solder reflow assembly in high-volume production lines.

Frequently Asked Questions
What is the current rating and blow characteristic of the SF-1206F500-2?
The SF-1206F500-2 is rated at 500mA with a fast-blow characteristic, meaning it interrupts the circuit very quickly when current exceeds the rated threshold. This fast response is critical for protecting sensitive ICs and MOSFETs in USB ports, battery protection circuits, and 5V logic rails from sustained overcurrent conditions.
What are the physical dimensions of the SF-1206F500-2 and how do they fit standard PCB footprints?
The SF-1206F500-2 measures 3.1mm in length, 1.55mm in width, and 0.6mm in height, matching the standard IPC 1206 SMD land pattern. This standard footprint allows the fuse to be mounted on PCBs using automated pick-and-place equipment, and the 0.6mm low profile supports thin device designs in portable electronics.
How does SF-1206F500-2 compare to a polyfuse (PPTC) for overcurrent protection in USB circuits?
Unlike a PPTC resettable fuse that automatically resets after cooling, the SF-1206F500-2 is a one-time fast-blow fuse that permanently interrupts the circuit when 500mA is exceeded. This distinction makes it preferable for applications where resetting after a fault would be unsafe, such as medical device power inputs or battery cell protection boards requiring positive circuit isolation after overcurrent events.
Is the SF-1206F500-2 suitable for automotive or industrial environments regarding temperature and compliance?
The SF-1206F500-2 carries RoHS-compliant (JESD-609 e3) lead-free construction and is designed to operate across the typical industrial temperature range of -55°C to 125°C. Its 1206 chip fuse body with 0.6mm height meets industrial PCB design requirements, though for AEC-Q200 automotive qualification, designers should verify lot-specific test certificates from Bourns.
