Product description Function: A 5 x 20 mm glass-tube sacrificial fuse with a 0.2 A cut-off current. Designed to interrupt the circuit when current exceeds the rated value, protecting either the load or the source from overcurrent and overload damage. Construction and size: Transparent glass tube (5 x 20 mm) that allows visual inspection of the element. Low internal resistance to minimize voltage drop during normal operation. Protection: Provides overcurrent and overload protection by acting as a replaceable sacrificial element; when the current exceeds 0.2 A the fuse opens and isolates the faulted section. Compatibility: Fits standard 5 x 20 mm fuse clips and holders and is suitable for any circuit that requires a 0.2 A fuse for protection. Use where a glass-tube form factor and a precise 0.2 A cutoff are specified. Key benefits — why you need it and how it helps Prevents component and circuit damage by reliably disconnecting power when current rises above 0.2 A. Low resistance construction maintains normal circuit performance while providing protection, avoiding unnecessary voltage drop in regular operation. Transparent glass body makes it easy to confirm a blown fuse without disassembly, simplifying troubleshooting and maintenance. Standard 5 x 20 mm size ensures easy replacement and broad compatibility with common fuse holders. Typical applications Small power supplies and wall adapters where a 0.2 A protection rating is required to protect downstream components. Consumer electronics, instrumentation, and audio equipment that use 5 x 20 mm glass fuses for circuit protection. Control panels, LED drivers, and low-current circuits where a visible, replaceable fuse is preferred for maintenance and safety. What it delivers Reliable overcurrent interruption at the specified 0.2 A rating. Simple drop-in replacement for any device designed around a 5 x 20 mm glass fuse. Clear visual indication of fuse condition and easy field replacement to minimize downtime.
