Product Description
Bourns MF-S350 Resettable Fuse provides efficient and reliable circuit protection with a voltage rating of 30V and hold current of 3.5A. This axial leaded fuse offers automatic reset functionality that allows it to switch rapidly from low resistance to high resistance under electrical overload conditions.
It is specifically designed to protect electrical and electronic circuits from excessive currents, supporting a current rating of 100A and typical trip current of 6.3A with a time to trip of 3 seconds. Its compact size (14mm length x 13.5mm width x 1.1mm height) and quarter hard nickel terminals ensure easy integration and excellent conductivity.
The fuse operates reliably across a wide temperature range from -40°C to 85°C and features very low internal resistance (minimum 0.017Ω) for minimal power loss, with a power dissipation rating of 2.5W. The bulk packaging type is suited for manufacturing environments requiring efficient insertion into machinery.
Bourns MF-S350 complies with RoHS environmental standards and the MFS series designation indicates it meets current industry standards for performance and durability. This fuse is maintenance free with an automatic reset cycle capability running for thousands of operations without replacement.
Common industrial applications include security systems, power supplies, power switching devices, automotive electronics, medical instrumentation, control systems, computers, peripherals, audio visual, and telecommunications equipment.
