FRM-A: ultra-compact and powerful

It is particularly the modest dimensions that make the SCHURTER FRM-A closed fuse holder a great one. Not only is it the most compact in its class, but it also shines with its enormous robustness and IP67 protection. Successful vibration, shock and salt mist tests confirm this in an impressive manner. The FRM-A has been developed exclusively for the SMT ceramic fuse DRM-A.

DRM-A: using gold against whisker

Tin whiskers represent a risk for short circuits in electronics. The underlying physical process has not yet been fully identified. However, the problem has always been circumvented by adding lead. But lead is often an undesirable element (RoHS guidelines). The DRM-A therefore completely dispenses with a lead-containing coating and relies on gold in its place. Gold-plated end caps offer no surface for whiskers to attack. The DRM-A, which was developed specifically for Avionics applications, is suitable wherever the highest demands are made on reliability and robustness. But this does not necessarily have to be at an altitude of 50,000 feet and installed in the FRM-A. Thanks to its design, it is also ideally suited for industrial and telecom applications.
