Key Features
- Fast-blow characteristic with 101 J joule integral for precise overcurrent protection in sensitive circuits
- Compact 3812 package measuring 10.1 mm × 3.1 mm body for space-efficient PCB mounting
- 3000 mA current rating with REACH and RoHS e4 compliance suitable for industrial and consumer electronics
Applications
The SF-3812FG3000T-2 is designed for overcurrent protection in power supply inputs, battery chargers, and consumer electronics where fast response to fault conditions is essential. Its 3000 mA fast-blow rating and compact 3812 body allow designers to place it directly in series with supply rails in portable devices and industrial control boards. The component is also used in automotive accessory circuits and USB power distribution systems requiring reliable 3 A fuse protection within a small footprint.

Frequently Asked Questions
What is the blow characteristic and joule integral rating of the SF-3812FG3000T-2 fuse?
The SF-3812FG3000T-2 is a fast-blow fuse with a joule integral of 101 J, which defines how much energy the fuse can absorb before opening. At a 3000 mA current rating, the fast-blow characteristic ensures the fuse opens quickly under overload or short-circuit conditions, protecting downstream components in power supplies, USB ports, and battery management circuits within milliseconds of a fault event.
What physical dimensions does the 3812 package offer, and how does it fit on a standard PCB?
The SF-3812FG3000T-2 uses a 3812 package with a body length of 10.1 mm and a body breadth and height of 3.1 mm each. This through-hole or surface-mount compatible form factor is widely supported by standard PCB footprint libraries. The compact 3.1 mm cross-section makes it suitable for mounting on boards with moderate component density where a 3 A fuse must fit without requiring a large keep-out zone.
When would SF-3812FG3000T-2 be preferred over a slow-blow 3 A fuse in a power circuit?
SF-3812FG3000T-2 is preferred when the protected circuit cannot tolerate sustained overcurrent even briefly, such as in sensitive analog front-ends, precision sensors, or USB host ports where a short circuit must clear within milliseconds. Slow-blow fuses are better for inductive loads with high inrush currents, like motors or transformers, because they tolerate a 3000 mA transient for hundreds of milliseconds without opening. For purely resistive or capacitive loads at 3 A, the fast-blow SF-3812FG3000T-2 provides tighter protection margins.
