Description and Introduction

PTC Resettable Fuses **Introducing the MF-USMD035-2: A High-Performance Resettable Fuse for Modern Electronics**  

In today’s fast-evolving electronics landscape, reliable circuit protection is essential to safeguard sensitive components from overcurrent events. The **MF-USMD035-2** from Bourns delivers precision and durability in a compact surface-mount package, making it an ideal solution for a wide range of applications.  

Designed for low-voltage circuits, this **PolySwitch® resettable fuse** offers a hold current of **350 mA** and a trip current of **700 mA**, ensuring robust protection while minimizing downtime. Its fast response to fault conditions helps prevent damage to connected devices, automatically resetting once the fault is resolved—eliminating the need for manual replacement.  

The **MF-USMD035-2** features a **small 1206 footprint**, making it suitable for space-constrained designs in consumer electronics, IoT devices, and industrial control systems. With an operating voltage of **30 VDC** and a wide temperature range of **-40°C to +85°C**, it performs reliably in demanding environments.  

Engineers will appreciate its **low resistance (0.25 Ω max)**, which reduces power loss and improves efficiency in power-sensitive applications. Additionally, its **UL and TUV certifications** ensure compliance with industry safety standards, providing peace of mind for critical designs.  

Whether integrated into battery packs, USB ports, or embedded systems, the **MF-USMD035-2** combines cutting-edge protection with long-term reliability. For engineers seeking a cost-effective, maintenance-free solution to overcurrent challenges, this resettable fuse stands out as a smart choice.  

Upgrade your circuit protection strategy with the **MF-USMD035-2**—where performance, safety, and efficiency converge.
