MFU Series SMD Chip Fuses

MFU Thin Film Chip Fuses are the perfect choice for the most fields of modern electronics

Beyschlag's MFU Series SMD Chip FusesThe new SMD chip fuse series MFU from Vishay is an over current protection device that avoids the risks of fire hazards caused by overload situations or short circuits on electronic devices, as well as enabling the engineering of low power electronics to design very small power circuits.

With a standard SMD size range of 0402, 0603, 0805, and 1206 and a rated current range of 0.5 A up to 6.3 A, the MFU series increases the safety level of electronic devices like cell phones, TFT-flat screens, notebooks, game consoles, DC/DC-inverters, control units, and motion control units. For circuits with higher requirements regarding miniaturization like cell phones or portable media players, the MFU 0402 offers the same electrical performance as the MFU 0603.

The homogeneous crystal structure of the metal layer has an important influence over the long-term stability, due to aging factors such as power dissipation or external high temperatures in combination with thermal cycles. To simultaneously improve control over the dimensions and crystal structure of the fuse element, Vishay Beyschlag MFU-series chip fuses are created using a thin film sputtering process. This process leverages precision chip resistor manufacturing knowledge and assembly capacity.

In addition, a special protective coating now raises the capability of MFU chip fuses to withstand harsh thermal shocks and wide-ranging humidity requirements.
