Thinnest, fused, undertab tantalum SMD chip capacitors

December 16, 2014 // By Graham Prophet
AVX has added a series of fused high CV tantalum SMD chip capacitors with undertab terminations.

F98-AS1 Series capacitors feature a proprietary lead-frame-less structure with precise dimensions and low stress packaging, an internal thin film fuse that protects against short circuits, and undertab termination technology which enables high volumetric efficiency and high PCB assembly density. Currently available in a 0805 (2012 metric) S case with four ratings (22µF/10V, 33µF/10V, 10µF/16V, and 1µF/35V) and a 0.9 mm maximum height, the F98-AS1 Series is positioned as the smallest and thinnest SMD fused tantalum product currently available. The series is suitable for use in a wide variety of applications in which safety and size are a primary concern.

The F98-AS1 Series capacitors are rated at 85°C and are designed for use in temperatures spanning -55°C to +125°C. The series is also lead-free compatible and RoHS compliant. Series extensions currently in development include a 0805 (2012 metric) case 47µF/10V capacitor and 10 capacitors packaged in 0603 (1608 metric) M cases: a 1µF/25V component, a 1µF/20V component, 10V components rated for 2.2µF, 4.7µF, 10µF, 22µF, and 33µF, and 16V components rated for 1µF, 2.2µF, and 4.7µF.
