Overview of SCHURTER MKF Surface Mount Fuse

The SCHURTER MKF datasheet summarizes the technical specifications, features, and compliance of the MKF series surface mount fuses. Designed to be compact in size (7 x 2.54 mm), these are quick-acting fuses (Type F) rated for 125VAC and 125VDC with a high breaking capacity. The fuses can be directly soldered onto printed circuit boards (PCBs).

Description and Applications

The MKF series comprises fuses suitable for use in various applications including telecommunications and household appliances. They come with a round solder pad design and are marked with their rated current for identification.

Technical Specifications

Ranging from 0.63A up to 15A, these fuses can operate in ambient air temperatures from -55°C to 85°C, as per the climatic category 55/085/56 in accordance with IEC 60068. They are made with a ceramic tube and tin-plated copper alloy end caps. For soldering, the datasheet recommends reflow or wave soldering profiles, and they are rated at Moisture Sensitivity Level (MSL) 1 according to J-STD-020.

Approvals and Product Standards

This fuse series adheres to the safety requirements listed in UL 248-14 for low-voltage fuses Part 14 and CSA 22.2 No. 248.14 for supplemental fuses. SCHURTER fuses comply with various guidelines, like CE, UKCA, and RoHS, ensuring their suitability for a wide range of markets and applications. Furthermore, the MKF series is designed for compatibility with IEC/UL 62368-1 for the safety of audio/video, information, and communication technology equipment.

Dimension and Soldering Characteristics

Key dimensions such as length, width, and pad size are clearly defined, with specific soldering pad recommendations given. Pre-arcing times across rated currents are specified, which detail the performance characteristics under various overload conditions.

Compliances

SCHURTER’s MKF fuses meet several regulatory demands. The CE and UKCA markings denote conformity with EU and British regulations respectively. They align with the European Union’s Restriction of Hazardous Substances (RoHS) Directive, China RoHS, as well as REACH, a European Community Regulation on chemicals and their safe use.
