Overview

The Littelfuse 263001L PICO II 263 Series Fuse is a high-reliability axial leaded fuse engineered for precise overcurrent protection in space-constrained electronic and industrial applications. Rated at 250V and 1A, this fast-acting fuse delivers rapid response to fault conditions while maintaining a compact footprint ideal for tight PCB layouts and miniaturized designs. The 263 Series supports a wide current rating range from 62mA to 15A across the entire family, allowing engineers to standardize on a single fuse platform for diverse project requirements. RoHS-compliant and available in halogen-free variants, the 263001L meets stringent environmental regulations without compromising performance. Its wide operating temperature range and low temperature rerating ensure consistent operation from -55°C to +125°C, making it suitable for automotive, industrial control, power supplies, and consumer electronics where thermal stability is critical. The axial lead design simplifies manual or automated insertion, reducing assembly time and cost. With a 250V rating, this fuse provides robust protection for both primary and secondary circuits in equipment operating on global power standards. The 263001L is manufactured in the USA by Littelfuse, a trusted leader in circuit protection with over 100 years of innovation. Use this fuse to safeguard sensitive components such as microcontrollers, sensors, LED drivers, and communication modules where even brief overcurrent events can cause catastrophic failure. The fast-acting characteristic ensures minimal let-through energy during fault events, preserving downstream circuitry integrity. Available in bulk packaging (0263001.MXL) for high-volume production environments.
