## Description

The Bourns MF-PSMF110X-2 is a surface-mount polymer positive temperature coefficient (PPTC) resettable fuse engineered for reliable overcurrent protection in space-constrained electronic designs. Built using a low-profile 0805 (2012 Metric) chip scale package with a symmetrical layout, this resettable PPTC thermistor features a holding current rating ($I_{hold}$) of 1.1 A and a trip current ($I_{trip}$) of 2.2 A at 23 °C. The component operates at a maximum DC voltage rating of 6 VDC and can safely interrupt fault currents up to a maximum interrupt rating of 40 A. With a rapid time to trip of 0.3 seconds under specified fault conditions, the device effectively limits excessive current to prevent thermal overload and component damage.

Designed to withstand rigorous operational environments, the MF-PSMF series functions reliably across an ambient temperature range of -40 °C to +85 °C, with thermal derating characteristics predictable up to maximum operating limits. The component utilizes nickel/gold-plated termination pads that comply with ANSI/J-STD-002 solderability standards, facilitating robust surface-mount assembly via standard lead and lead-free solder reflow profiles. Constructed to be halogen-free and RoHS compliant, the device exhibits high stability against environmental aging, including passive thermal aging, humidity exposure, and mechanical vibration.

This surface-mount resettable fuse is well-suited for high-density circuit protection applications prone to transient overcurrents or short circuits. Typical integration points include USB 2.0, 3.0, and OTG port protection, HDMI 1.4 source protection, mobile phone battery and peripheral interfaces, PC motherboard plug-and-play circuits, game console ports, and automotive electronic control modules. The compact 0805 footprint combined with tape-and-reel packaging (3000 pieces per reel) supports automated pick-and-place manufacturing workflows in modern consumer, industrial, and automotive electronics.
