BOURNS SinglFuse™ SF-1206S Series Slow-Blow Fuse - 32V 6A

The BOURNS SinglFuse™ SF-1206S Series Slow-Blow Fuse represents a high-reliability surface-mount device (SMD) engineered for critical overcurrent protection in modern, compact electronic circuits. Designed with a standard 3216 (EIA 1206) footprint, it is perfectly suited for automated pick-and-place assembly processes, streamlining production for a wide range of consumer and industrial electronic devices.

As a slow-blow, or time-lag, fuse, it is specifically crafted to tolerate temporary inrush currents, such as those encountered during the power-up of capacitive or inductive loads, without nuisance blowing. This characteristic makes it an ideal choice for protecting power supplies, motor controllers, and other circuits where initial surge currents are expected. The fuse ensures reliable protection under sustained overloads, opening decisively to safeguard sensitive components downstream.

Constructed using a robust thin-film process on a ceramic substrate with tin (Sn) plating, the fuse offers excellent electrical and thermal stability. It is UL recognised, compliant with RoHS directives, and manufactured with halogen-free materials, aligning with stringent environmental and safety standards for global electronic applications. This combination of features provides designers with a dependable, space-saving solution for circuit protection that does not compromise on performance or regulatory compliance.

Key Characteristics & Applications

• High Breaking Capacity: Capable of safely interrupting high fault currents up to 50A at its rated voltage, ensuring system safety during severe short-circuit events.
• Low Resistance: A typical resistance of just 13mΩ minimises power loss and voltage drop within the circuit, contributing to overall system efficiency.
• Predictable Performance: Characterised by a typical I²t (let-through energy) value, allowing for precise coordination with other circuit
