What are the key features of MF-NSHT016KX-2?
- 160 mA hold current with automatic reset after fault clearance eliminates manual fuse replacement in field-deployed equipment
- Compact 3.4 mm x 1.8 mm x 0.85 mm SMT chip package fits tight PCB layouts alongside other surface-mount components
- PTC thermistor technology limits fault current by increasing resistance with temperature, protecting downstream ICs and cables
- RoHS-compliant lead-free construction meets international environmental and supply chain compliance requirements
What is MF-NSHT016KX-2 used for?
The MF-NSHT016KX-2 is used for board-level overcurrent protection in USB ports, portable consumer electronics, and IoT device power inputs where a 160 mA nominal current path must be protected against short circuits or overloads. Its automatic-reset PTC behavior is preferred over one-time fuses in applications where field access for replacement is impractical, such as sealed enclosures or embedded industrial modules. The compact SMT footprint integrates with standard 0603 or 1206 passive component placement processes.

Frequently Asked Questions
What is the hold current rating of MF-NSHT016KX-2 and how does that define its application range?
The MF-NSHT016KX-2 has a hold current of 160 mA at 23 °C, meaning it remains in its low-resistance state for sustained currents up to 160 mA. For trip currents typically 2x the hold current (approximately 320 mA), the PTC resistance rises sharply to limit fault current. This makes it appropriate for protecting USB 2.0 ports, low-power sensor nodes, and signal-level power rails where normal operating current stays below 160 mA.
How does the resettable PTC mechanism of MF-NSHT016KX-2 differ from a conventional one-time fuse?
Unlike a one-time blow fuse, the MF-NSHT016KX-2 uses a polymer PTC material that dramatically increases resistance when self-heated by fault current, limiting the fault to a safe level. Once the overcurrent condition is removed and the device cools, its resistance returns to the normal low-resistance state within seconds to minutes, restoring normal circuit operation. This automatic reset eliminates the need for field service or board replacement after a fault event.
What are the physical dimensions of MF-NSHT016KX-2 and which SMT package footprint does it use?
The MF-NSHT016KX-2 measures 3.4 mm length x 1.8 mm width x 0.85 mm height in a rectangular SMT chip package. This footprint is close to a 1206 chip component size, allowing it to share a PCB pad library with standard passive components. The surface-mount style is compatible with standard pick-and-place and reflow soldering processes used in volume SMT production.
Can MF-NSHT016KX-2 protect a USB port power line, and what happens during a short-circuit event?
Yes. A USB 2.0 port that supplies up to 100 mA to 500 mA operates within the range addressable by the MF-NSHT016KX-2's 160 mA hold current. During a short-circuit event, the fault current heats the PTC element above its trip threshold, causing resistance to rise from milliohms to hundreds of ohms within milliseconds, dropping most of the supply voltage across the fuse and protecting the downstream circuitry. The device resets automatically once the short is cleared and the board is powered down briefly.
