Built to the standardized metric dimensions of 5mm x 20mm (imperial 0.2" x 0.79"), this glass tube fuse features nickel-plated copper alloy endcaps designed for reliable insertion into standard clips and fuseholders. With a rated current of 630 mA and a voltage rating of 250 VAC, it offers a low breaking capacity of 35 A at 250 VAC and adheres strictly to IEC 60127-2 standards for supplementary circuit protection. Operating with a time-lag (Time Delay / Slow-Blow, Characteristic T) blow profile, this component accommodates temporary inrush currents and transient startup surges without nuisance tripping, making it well-suited for power supply inputs, audio/video systems, and industrial control architectures complying with IEC/UL 62368-1 safety requirements. It features a maximum voltage drop of 300 mV at 1.0 In, a typical melting integral ($I^2t$) of 4.35 $A^2s$, and is rated for a wide admissible ambient air temperature range of -55Β°C to 125Β°C. Supported by international safety approvals including VDE, UR, CCC, and CQC, this RoHS and REACH-compliant device delivers dependable fault interruption for demanding electronic applications. ## Specifications | Parameter | Value | |---|---| | Svhc | No SVHC (04-Feb-2026) | | Fuse Current | 630mA | | Product Range | FST | | Fuse Size Metric | 5mm x 20mm | | Fuse Size Imperial | 0.2" x 0.79" | | Voltage Rating Vac | 250V | | Blow Characteristic | Time Delay | | Breaking Capacity Current Ac | 35A | ## Datasheet πŸ“„ [Download PDF](https://novapart.co/datasheet/farnell:1360808/) **Fuses** FST 5x20 https://www.schurter.com /PG01_2 Miniature Fuse, 5 x 20 mm, Time-Lag T, L, 250 VAC ## IEC 60127-2 Β· 250 VAC Β· Time-Lag T See below: ## **Approvals and Compliances** ## **Description** - IEC Standard Fuse - L = Low Breaking Capacity (Glass Tube) ## **Applications** - Primary Protection in Equipment ## **References** Pigtail Type FST 5x20 Pigtail Assembled Fuseholder Fuse Kit Fuse Kit FST 5x20; Fuse Kit FST 5x20 / SP 5x20 **Weblinks** pdf data sheet, html datasheet, General Product Information, DistributorStock-Check, Detailed request for product Application Note Primary Protection in Equipmentwith further information on increased Pulse Strength and their test conditions according to international standards see Impulse Withstand Voltage |**Technical Data**|| |---|---| |Rated Voltage|250 VAC| |Rated current|0.05-20 A| |Breaking Capacity|35 A-200 A| |Characteristic|Time-Lag T| |Admissible Ambient Air Temp.|-55Β°C to 125Β°C| |Climatic Category|55/125/21 acc. to IEC 60068-1| |Material: Tube|Glass| |Material: Endcaps|Nickel-Plated Copper Alloy| |Unit Weight|1 g| |Storage Conditions|0Β°C to 60Β°C, max. 70% r.h.| |Product Marking|, Rated current, Rated Voltage, Cha-
