What are the key features of 1812L260/12MR?
- 2.6 A hold current with 5.2 A typical trip current at 23°C, providing precise overcurrent protection for 12 V USB power and battery management circuits
- 1812 SMT package (4.73 mm x 3.41 mm x 1.34 mm) with rectangular footprint enabling reliable surface mount reflow soldering at standard 260°C profiles
- Resettable PTC polymer technology automatically restores normal conductance after fault clearance, eliminating manual fuse replacement in field-deployed equipment
What is 1812L260/12MR used for?
The 1812L260/12MR resettable fuse is commonly used in USB power distribution boards, battery pack protection circuits, and AC/DC power supply outputs operating at up to 12 V where 2.6 A continuous current must be protected against short-circuit and overload conditions. Its PTC self-resetting behavior makes it ideal for consumer electronics, IoT gateways, and industrial panel equipment where replacing blown fuses in the field is impractical. Surface mount assembly in the 1812 package simplifies PCB layout for automated production lines supplying compact power management modules.

Frequently Asked Questions
What hold current and trip current does the 1812L260/12MR support at room temperature?
At 23°C, the 1812L260/12MR has a hold current of 2.6 A (the maximum current it passes indefinitely without tripping) and a trip current of approximately 5.2 A, meaning it will self-reset after clearing any fault current exceeding 5.2 A on a 12 V circuit.
For a USB power delivery board running at 12 V, how does the 1812L260/12MR protect downstream components?
On a 12 V USB power rail, the 1812L260/12MR limits sustained fault current by increasing its PTC resistance within milliseconds when current exceeds approximately 5.2 A, clamping power dissipation to a safe level and protecting downstream ICs, cables, and connectors from thermal damage during short-circuit events.
What are the physical package dimensions of the 1812L260/12MR and how does its footprint compare to smaller 1206 resettable fuses?
The 1812L260/12MR measures 4.73 mm (length) x 3.41 mm (width) x 1.34 mm (height) in the 1812 SMT package, which is physically larger than the 1206 package (3.2 mm x 1.6 mm) to accommodate the higher 2.6 A hold current rating and the additional PTC polymer mass needed for reliable thermal trip performance.
