Mersen J208227 MISIPTF76 open-type single-pole miniature fuse base for 5 x 20 mm cartridge fuses, rated at 6.3 A and 250 V AC for printed circuit board mounting.
£0.67
The Mersen J208227 is a compact open-type miniature fuse base designed to securely accommodate standard 5 × 20 mm cartridge fuses. Also identified by the catalogue reference MISIPTF76 and designation SI PTF 76, it provides a simple and reliable fuse mounting solution for printed circuit boards and electrical equipment.
Part of the Mersen IEC Miniature Fuse Bases range, the J208227 is rated for operation at up to 250 V AC and 6.3 A. Its open construction provides convenient access to the installed fuse, making inspection and replacement straightforward where protection against direct contact is not required.
The fuse base features solder-pin terminals for direct printed circuit board mounting. Its flame-retardant UL94 V-0 material, low contact resistance and broad operating temperature range make it suitable for dependable circuit protection within industrial controls, electronic assemblies and OEM equipment.
Miniature fuse bases provide a secure connection point between a replaceable cartridge fuse and the protected electrical circuit. When fitted with a correctly selected fuse, the J208227 helps protect electronic equipment against overload and short-circuit conditions.
The open design is particularly suitable for equipment housings and internal assemblies where the fuse base is inaccessible during normal operation. Its compact dimensions and solder-pin mounting make it easy to integrate into new printed circuit board designs and replacement applications.
