Schurter announces several new current ratings to its already popular UMT 250 series, for a total of twenty two unique ratings from 80mA to 10A. The series is designed to provide overcurrent and short-circuit protection in both primary and secondary circuits. The versatile one package solution streamlines design, procurement and automated assembly processes.
The UMT 250 maximizes circuit protection while its extremely compact size meets the demand for saving space and facilitating production. It can be mounted on both sides of the printed circuit board. Its low profile increases production rates when mounted with pick and place assembly machines. It is an ideal substitute for axial and radial leaded through-hole fuses where bending leads can cause assembly delays.
The Universal Modular Fuse (UMF) is time-lag (T) characteristic. It is rated at 250 VAC and 125 VDC, according to IEC and 277VAC and 250 VDC, according to UL. The series has a high breaking capacity of up to 200A at rated voltage. It is RoHS compliant and carries all the main approvals such as VDE, UL LISTing, cURus, PSE Jet (Japan), CCC (China) and KTL (Korea). Applications include protection of power supplies, storage systems, wireless base stations and many other electronic systems.
The UMT 250 is packaged in plastic bags of 100 pieces or taped reels for automated assembly.
SCHURTER released today the first 1206 chip fuse series UST 1206 with rated current values up to 25 A and slow-blow characteristic. It boasts high melting I2t values, which provides good inrush withstand performance. It’s a cost-effective solution for applications in which high inrush current and on-off cycling are present.
The UST 1206 with characteristics according to UL 248-14 complements the previously introduced and successful USI 1206 with characteristic according to IEC 60127-4. The current ratings of the UST 1206 range from 7 to 25 A with voltage ratings up to 63 VDC and 32 VAC. The device provides a breaking capacity of up to 400 A at defined voltage and an operating temperature range of - 55C to +90C.
The fuse is designed to provide secondary over current protection in power inverters, back lighted DC-AC inverters for monitors, wherein power consumption is high at a low voltage level, e.g. 5 or 12 VDC.
The legend marking on each fuse allows a clear visual identification. The fuse is approved according to UL 248-14 and holds a cURus approval. The device is RoHS compliant and is supplied on tape and reel either with 1k or 5k or 15k pieces.
It complies with ESA/ESCC Generic Specification No. 4008 for use in space. SCHURTER is the only European supplier of fuses holding this qualification, by virtue of its great competence and comprehensive know-how.
The MGA-S type fuse meets the high standards of the aerospace industry which requires hermetically encapsulated and rugged designs. MGA-S is manufactured using thin film technology. Rated for nominal currents from 140 mA to 3,5 A, it also features consistent minimal and maximal melting times under excess current conditions, irrespective of the operation mode, e.g. in a vacuum environment. Its small dimensions of 3.2 x 1.55 mm make it unique among fuses in this market segment.
MGA-S is especially suited to the protection of “payloads” often connected to DC power supplies such as those used in satellites, ensuring that in the event of a malfunction, such a payload is securely disconnected and will not cause any other systems to fail.
Lucerne, SCHURTER launches a component library with popular PCB components for Allegro and Orcad from Cadence. Electronics engineers will get the most important product information for the design of a printed circuit board in his preferred tool.
The new library offering contains schematic information for placement in equipment circuit diagrams and lets the designer select the relevant parameters suitable to his design from the supplied database. The actual simulation sources and references to the data sheets are also accessible from the database. The geometry of the pads matches the component dimensions and the pads are designed according to standard industry practices and assembly methods. Positioning information as well as solder mask layout is available in addition to the pad design. SCHURTER offers the designer a guaranteed pad design that enables the user to develop integrated circuit boards quickly and helps ensure their manufacturability.
