Schurter launches the open fuse holder
OGN-SMD in blister tape and in with fuse-links assembled versions
Do you use an open SMD-fuse holder with 5x20 fuse-links and would like to reduce the process steps when assembling and therewith significantly save time and money?
Schurter now offers a solution by offering the already existing product OGN-SMD also in blister tape of 400 pieces per roll. This new offer includes a wide range of with fuse-links pre-assembled products and optionally with cover as well.
The fuse-links are versions of the quick acting, time lag and super time lag Schurter standard types FSF, FST and FTT, which show the necessary solder resistance. They have the characteristic and approvals of the corresponding Schurter catalogue types and cover a range of 50mA to 10A.
These products are used almost in all classical 5x20 applications areas as circuit protection in the household area, for manufacturing automats, battery chargers, measuring equipment, laboratory equipment, etc.
The OGN-SMD parts from Schurter are deliverable in blister tape of 400 pieces per roll.

5 x 20 SMD Fuses
SMD 5x20mm fuses cut space, as well as assembly time and expense because they are soldered directly onto the printed circuit board (PCB).
Gold plated end-caps allow for direct solder to the PCB and enable the fuses to easily withstand the heat of the soldering process. This simple solution eliminates the need for conventional axial leads (or pig-tails), which consume more board space and can jam during auto insertion because of lead-to-hole misalignment.
The FST/SPT series includes the same slow reaction time as the standard time-lag 5x20mm fuses according to IEC 127-2. The FTT offers a super time-lag opening. Time-lag fuses withstand current surge or repeated pulse currents.
The FST has a current range of up to 20 Amps at 250 Volts AC. The SPT type offers a high-breaking capacity of up to 1500 Amps at 250 Volts AC, allowing for safe interruption of dangerous fault.
