LITTELFUSE 466 Series SMD Fuse, Very Fast Acting, 1206, 63V, 2A

The LITTELFUSE 466 Series SMD Fuse (0466002.NR) is a 2A/63V, very fast-acting surface-mount fuse engineered for precision and reliability in compact, secondary circuit protection. Its advanced high-temperature substrate body, combined with a conformal coating element cover, ensures robust performance and durability in demanding environments.

The device features a 100% tin-plated over nickel over copper termination, guaranteeing excellent solderability and compatibility with modern lead-free solders and higher temperature reflow profiles. The alloy-based element construction provides superior inrush withstand characteristics (I²t), outperforming traditional ceramic or glass-based 1206 chip fuses, making it ideal for applications experiencing high initial current surges.

Designed for space-constrained applications, this small, thin-film 1206-size fuse offers a low profile suitable for height-sensitive designs. The flat top surface facilitates reliable automated pick-and-place operations during assembly, streamlining production. For easy identification, the product is clearly marked on its top surface with a code that denotes its amperage rating, eliminating the need for post-installation testing.

With its precise electrical characteristics, including a nominal voltage drop of 78.73mV, nominal power dissipation of 0.1575W, and a nominal cold resistance of 0.031Ω, this fuse ensures efficient and predictable operation within its specified -55 to 90°C temperature range. Its high breaking capacity of 50A AC/DC provides dependable protection against overcurrent events.

Ideal for safeguarding sensitive electronics, this fuse is a critical component for ensuring the safety and longevity of circuits in portable devices, consumer electronics, computers, and computer peripherals, offering a superior blend of performance, size, and reliability.
