SCHURTER released today the industry's first IEC quick-acting (F) chip fuse series USI 1206, Universal Modular Fuse (UMF). It is approved according to IEC 60127-4/2, and bears international approvals by cURus, METI and CCC.

The new fuse series has high melting I²t values, which provides greater withstand against high inrush or pulse currents. Its opening time compares to 1206 time-delay types according to UL in lower overcurrent conditions. Conversely, the fuse responds very quickly to higher overcurrents in the event of a fault condition. Current ratings range from 0.5 to 6.3 A with voltage ratings of 63 VDC and 32 VAC. The device has a breaking capacity of 63 A at rated voltages and an operating temperature range of - 55 °C to +90 °C.

The USI provides optimal secondary overcurrent protection in power inverters and low-voltage power supplies in an extremely small package 1206 (3.2 mm x 1.6 mm x 0.6 mm). It is also ideal for protection of integrated display and storage subsystems, portable medical devices and sensor-rich in-car electronics where reliability of performance is critical. The thin film technology process used to produce the fuse yields very predictable and stable performance results, as each fuse passes through the testing procedure in order to qualify for use in the most sensitive electronic systems.

The device supports lead (Pb)-free soldering in reflow, or vapor phase processes and is RoHS compliant according to the EU-Directive 2002/95/EG. It is supplied on tape either with 1k, 5k or 15k pieces. Each fuse is marked for clear visual identification. Delivery is stock to six weeks.

Datasheet

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.

Datasheet

SCHURTER's new SMD-fuse type MGA-S meets the standard of ESA/SCC Generic Specification No 4008 for space applications.

Based on the design of Schurter's existing MGA, the new version meets the requirements of the space industry and its demands for a fuse product with hermetic seal and robust construction, such that with a disconnection, no arcs or gasses can escape. The requirements also include additional pre-arcing times, consistency of over-current disconnects at rated voltage regardless of vacuum conditions, stable derating curves at higher ambient temperatures, and durability against mechanical vibration and shock.

The technology widely used for standard fuses today is not able to fulfil the requirements for a long-term reliability of 20 to 30 years. This long-term stability is influenced by leakage loss, ageing and ambient temperature in combination with thermal cycles, which are quite prevalent in satellite applications. This is mainly due to the ageing phenomena of the traditional tinned fuse links. The MGA-S with its thin film technology (metal sputter process) increases the long-term stability of the fuse through the homogeneous crystal structure of the metal layers.

Its small dimensions in a popular 1206 footprint [3.2 mm by 1.55 mm] make the MGA-S the smallest SMD fuse qualified for use in equipment for space. Applications include equipment that is launched into orbit with a specific focus on satellite power system architectures operating up to 125 VDC in vacuum environments. This includes protection of power supplies, batteries and solar arrays.

The MGA-S is the only European manufactured SMD fuse for space applications. It is built according to UL 248-14 and CSA 22.2 no. 248-14 and carries UL and CSA recognition. It is also tested according to Mil-Std 202, Method 108A, 103B, 106E, 107D, 211A & 215A.
