Key Features
- 0.30 A rated current surface-mount chip fuse with minimum resistance (Rmin) characteristic at 23°C enabling precise overcurrent protection for sensitive low-current circuits
- Compact rectangular chip package measuring 4.73 mm x 1.1 mm for space-efficient SMT integration on dense PCBs in consumer and industrial electronics
- RoHS and REACH compliant construction (JESD-609 code e4) meeting global environmental and hazardous substance regulations for international market access
Applications
The PFMF.030.2 surface-mount chip fuse is used in overcurrent protection circuits for sensitive electronic subsystems requiring reliable protection at 0.30 A continuous current, such as battery management circuits, USB power path protection, and low-power sensor interfaces. Its compact 4.73 mm x 1.1 mm SMT form factor integrates directly on PCBs in consumer electronics, industrial IoT devices, and medical instrumentation where board space is constrained. The minimum resistance characteristic at 23°C minimizes series voltage drop in precision analog and battery-powered circuits sensitive to resistive losses.

Frequently Asked Questions
What current rating and package dimensions does the PFMF.030.2 chip fuse provide?
The PFMF.030.2 is rated at 0.30 A continuous current and housed in a rectangular surface-mount chip package measuring 4.73 mm in length and 1.1 mm in height. This compact chip fuse form factor allows integration directly on PCBs using standard SMT reflow soldering, making it suitable for protecting low-power circuits in sensor modules, USB interfaces, and battery management systems operating below 0.30 A.
What does the Rmin characteristic at 23°C mean for the PFMF.030.2 in precision circuit designs?
The Rmin at 23°C specification indicates that the PFMF.030.2 is characterized at a minimum resistance value measured at room temperature (23°C), which helps circuit designers predict the exact series resistance contribution of the fuse in the signal or power path. For precision analog circuits and battery-powered sensors where even a few milliohms of series resistance affect measurement accuracy or battery discharge characteristics, knowing the minimum cold resistance helps designers calculate worst-case voltage drops and efficiency losses accurately.
How does the PFMF.030.2 comply with RoHS and REACH environmental regulations?
The PFMF.030.2 carries a JESD-609 code of e4, indicating that it is manufactured without lead (Pb) and uses only RoHS-compliant materials. SCHURTER also lists the part as REACH compliant, confirming that restricted hazardous substances are below threshold concentrations. This dual compliance allows the PFMF.030.2 to be designed into products sold in the European Union, the United Kingdom, and other markets with RoHS or REACH import restrictions without requiring material declarations or exemptions.
In which low-current protection applications is the PFMF.030.2 a preferred surface-mount fuse choice?
The PFMF.030.2 is preferred in USB 2.0 bus power protection circuits limited to 0.5 A where the 0.30 A rating provides upstream overcurrent protection for connected peripheral devices, in lithium-ion cell protection boards where primary cell current is below 0.30 A, and in industrial IoT sensor nodes with current-limited power rails. Its 4.73 mm chip package and SMT mounting also make it suitable for wearable electronics and medical monitoring devices where board area and mass constraints favor chip fuses over leaded through-hole alternatives.
