Key Features
- 2.6 A hold current with 16 V maximum voltage rating for overcurrent protection in 5 V to 12 V power rails
- Self-resetting PTC polymer technology automatically recovers after fault clearance — no manual fuse replacement required
- Compact SMT package (4.83 mm x 3.41 mm x 1.52 mm) enables board-level integration in space-constrained designs
- RoHS compliant and Pb-free (JESD-609 e3) for use in lead-free manufacturing processes
Applications
The MINISMDC260F/16-2 is used to protect USB ports, battery chargers, and DC power distribution rails operating at up to 16 V where repeated overcurrent faults are expected. Its 2.6 A hold rating is well suited for 5 V to 12 V power lines in industrial IoT gateways, consumer electronics hubs, and portable instrument chargers. The self-resetting nature eliminates field service interruptions caused by blown fuses in hard-to-access equipment.

Frequently Asked Questions
What are the hold current and voltage ratings of the MINISMDC260F/16-2?
The MINISMDC260F/16-2 has a 2.6 A hold current and a 16 V maximum voltage rating. The trip current threshold is typically around 5.2 A (2x hold current), at which point the PTC element transitions to a high-resistance state within milliseconds, limiting fault current to a safe level on the protected 5 V to 12 V rail.
How does the PTC resettable mechanism in this Littelfuse device benefit a USB power distribution design?
Unlike one-time blade or glass fuses, the polymeric PTC in MINISMDC260F/16-2 automatically resets to its low-resistance conducting state once the overcurrent fault is removed and the device cools below its trip temperature, typically within 10 seconds to 60 seconds. This means a USB port protected by this device can recover from a 2.6 A overload without board access or manual intervention, reducing field service costs in multi-port USB hubs.
What SMT package dimensions does MINISMDC260F/16-2 use, and how does it fit in a compact PCB layout?
The MINISMDC260F/16-2 is housed in a rectangular SMT package measuring 4.83 mm in length, 3.41 mm in width, and 1.52 mm in height. This footprint occupies approximately 16.5 mm² of PCB area, compatible with standard reflow soldering and fitting within typical 5 mm x 4 mm keepout zones used in dense power management layouts.
Is MINISMDC260F/16-2 a suitable overcurrent protector for a 12 V industrial IoT gateway power input?
Yes, with its 16 V maximum voltage rating and 2.6 A hold current, the MINISMDC260F/16-2 is appropriate for protecting 12 V DC input rails carrying up to 2.6 A continuously. It will trip at approximately 5.2 A, protecting downstream 12 V to 5 V converters and microcontroller modules from short-circuit currents while automatically restoring power once the fault condition clears.
