Présentation
Description
- Current Rating: 500 mA (0.5A)
- Voltage Rating: 32V DC
- Fast-Acting: Quickly interrupts excessive current to protect circuits.
- 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 systems, it ensures reliable protection in space-constrained applications. Its low resistance and high durability make it ideal for sensitive circuits.
For detailed specs, refer to the manufacturer’s datasheet.
Equivalent
- Littelfuse 0501.050 (500mA, 50V)
- Bourns MF-MSMF050 (500mA, 50V)
- TE Connectivity 0ZCM0050FF2E (500mA, 50V)
- Eaton MF-NSMF050 (500mA, 50V)
These are SMD fuses with similar ratings (500mA, 50V) and package sizes (0402/1005 metric). Verify specs for exact compatibility.
Features
- Current Rating: 500mA (0.5A) hold current.
- Voltage Rating: 30V DC max.
- Compact Size: 0805 footprint (2.0 × 1.25mm).
- Trip Current: 1A (typical).
- Fast Response: Quickly resets after fault removal.
- Operating Temp: -40°C to +85°C.
- Low Resistance: <0.25Ω typical.
Ideal for overcurrent protection in compact electronics like portable devices, IoT, and PCBs.
Pinout
- Pin Count: 2 (standard SMD design with two terminals).
- Function: Acts as a fast-acting fuse (rated for 50V and currents up to 2A, depending on the variant). It protects circuits by breaking the connection during overcurrent or short-circuit conditions.
Key features include a small footprint (e.g., 0603 or similar size) and low resistance, making it suitable for high-density PCBs.
For exact specifications (e.g., current rating, package size), refer to the datasheet for your specific model variant.
Manufacturer
Application
- Consumer Electronics (smartphones, tablets, wearables).
- IoT & Wireless Devices (sensors, modules).
- Portable Devices (power banks, USB hubs).
- Automotive Electronics (infotainment, lighting).
- Industrial Controls (PCBs, low-power circuits).
It offers fast response, self-recovery, and space-saving SMD packaging, ideal for protecting sensitive circuits from short circuits and overloads.
