Overview
The datasheet provides detailed specifications for the SCHURTER FSQ 5 X 20 miniature fuses. These are quick-acting, non-resettable fuses that come in a glass tube design and are commonly used in electronic circuit protection. They are designed according to UL 248-14 and CSA C22.2 No. 248.14 standards and have been granted GSA approvals.
Electrical Characteristics
The fuses are available in a wide range of rated currents, from 400 mA to 3.5 A. They have a breaking capacity of 10 000 A at 125V AC with a power factor (p.f) of COS $\phi$ 0.7-0.8, and 35 A at 250V AC with the same power factor. Additionally, the fuses can sustain a maximum non-fusing current (Inf) for specific durations: up to 4 hours for the lower limit and 1 hour for the upper limit of the rated current spectrum.
Performance Parameters
Pre-arcing time/current characteristic at an ambient temperature of 23°C is provided, indicating the fuse’s behavior under multiple rated current conditions. The voltage drop and sustained power dissipation are provided as typical values, ensuring the users can determine the amount of energy dissipated by the fuse under normal operation. Voltage drop values vary from 170 to 740 mV, and sustained power dissipation values are offered for different rated currents.
Ordering Information
For ordering, the datasheet states the unique Order No. as 0034.3969, which is essential for users to obtain the correct fuse specifications for their requirements.
Website and Standards
The official SCHURTER website is referenced as www.schurter.com for additional information. The fuses comply with standard safety and performance specifications outlined in UL 248-14 and CSA C22.2 No. 248.14, indicating their suitability for usage in various devices that require reliable overcurrent protection.
