Press Release Summary:

The SUT-H Ceramic Fuse is designed for applications with high inrush current and comes in 6.3 x 32 mm dimensions with rated current range from 10 A to 50 A. The product comes with axial leads for direct mounting on PCB or without leads for insertion into solid beryllium-copper fuse clips. The fuse meets UL 248-14, cURus and RoHS standards. The SUT-H fuse features a breaking capacity up to 500 A at 250 VAC and 10 kA at 125 VAC.

Original Press Release:

SUT-H 6.3x32 mm Ceramic Fuse Sustains High Inrush Currents

Santa Rosa, California, November 20, 2018 – SCHURTER introduces a new 6.3x32 mm ceramic fuse with a rated current range from 10 A to 50 A. The SUT-H is particularly suited for applications with high inrush currents. 

In contrast to SCHURTER’s standard SUT, the SUT-H has a much higher melting integral, which makes it extremely pulse resistant to high inrush currents, as in providing absorption of such occurrences in power supply units. The fuse series also has a high breaking capacity up to 500 A @ 250 VAC, 10 kA @ 125 VAC. 

The SUT-H is offered with axial leads for direct mounting on the PCB or without leads for insertion into SCHURTER’s solid beryllium-copper fuse clips, series CQP. The clips are rated for use up to 30 A, which is substantially higher than conventional tin-plated clips, which are often limited to a maximum operating current of 10 A. 

The new 6.3x32 mm SUT-H ceramic fuse opens up completely new areas of application, due to the extended rated current range up to 50 A. It also provides for more compact innovative application designs. The fuse series meets the requirements of the UL 248-14 standard. It is cURus approved and RoHS compliant. 

Pricing for the SUT-H version without leads starts at $.47 each at 1K pieces. It is supplied in 10 packs. The leaded version is $.60 each and supplied in bulk 1K pieces.
