Overview

Description

The MICROSMD005F-2 is a miniature surface-mount fuse designed for overcurrent protection in compact electronic circuits. Key features include:
- Current Rating: 500 mA (0.5A)
- Voltage Rating: 32V DC
- Fast-Acting: Quick response to overcurrent conditions
- Compact Size: Ultra-small form factor (e.g., 0402 or similar) for high-density PCBs
- Agency Approvals: Typically meets UL/CSA/IEC standards
Commonly used in portable electronics, IoT devices, and automotive applications, it safeguards sensitive components from short circuits and excessive current. Its surface-mount design ensures easy integration into automated assembly processes.
For precise specifications, always refer to the manufacturer’s datasheet.

The MICROSMD005F-2 is a resettable fuse (PPTC). Equivalent products include:
- Bourns MF-R005
- TE Connectivity RUEF005
- Littelfuse 0505L005WR
- Raychem PolySwitch 1812L005
These alternatives offer similar 0.05A hold current and 30V ratings. Verify specs like trip time and max current for exact compatibility. Always check datasheets for precise substitution.

Features

The MICROSMD005F-2 is a resettable fuse (PPTC) with the following key features:
- Current Rating: 0.05A (50mA) hold, 0.10A (100mA) trip
- Voltage Rating: 30V DC
- Compact Size: 0402 (1005 metric) SMD package
- Fast Trip Response: Protects against overcurrent and short circuits
- Resettable Function: Automatically resets after fault removal
- Low Resistance: Typical <1.5Ω for minimal power loss
- Operating Temp Range: -40°C to +85°C
Ideal for protecting sensitive electronics in space-constrained applications.

Application

The MICROSMD005F-2 is a surface-mount fuse used in compact electronic devices for overcurrent protection. Key application areas include:
- Consumer Electronics (smartphones, tablets, wearables).
- Automotive Electronics (infotainment, sensors, lighting).
- Industrial Equipment (PLC, control systems).
- Telecommunications (routers, modems).
- Medical Devices (portable diagnostics, monitoring).
Its small size (0402 footprint) and fast-acting characteristics make it ideal for space-constrained, high-reliability circuits.
