Why Choose the Mersen D208199 High-Speed Semiconductor Fuse?
The Mersen D208199 is a compact high-speed semiconductor protection fuse developed to safeguard sensitive electronic components against damaging overcurrents and short circuits. Also identified by the catalogue number MI6FAP50V0.2, this miniature fuse provides very fast fault interruption for semiconductor circuits and industrial electronic equipment.
With a rated current of 0.2 A and a rated voltage of 500 V AC, the D208199 is suitable for low-current circuits where rapid and precise protection is essential. Its low melting and clearing I²t values restrict the energy passing through the circuit during a fault, helping reduce electrical and thermal stress on valuable components.
The fuse uses a durable 6.3 × 32 mm ceramic body with axial leads for direct soldering onto printed circuit boards. This compact construction makes it ideal for converters, control systems, power supplies and electronic assemblies requiring dependable PCB-mounted semiconductor protection.
