What's New @ AVX - Issue 7

TBW SeriesMilitary Fused Tantalum CapacitorSolid tantalum capacitors are very reliable and can accommodate a large variety ofenvironmental conditions. Because of this high reliability, tantalums are seeing increased usage inmore harsh applications. Many of these environmental conditions may cause the capacitor to fail(short) and not allow the capacitor to take advantage of the inherent self healing mechanism. As asafety factor in these applications, AVX has developed a new fused tantalum capacitor. Thestandard fused tantalum on the market today from other manufacturers uses a bi-metallic fusewire. The single wire fuse limits flexibility in design and can increase the Equivalent SeriesResistance (ESR) of the complete package. The AVX (TBW) fused capacitor takes advantage of theAVX thin film fuse technology. By replacing the bi-metallic fuse wire with a thin film fuse, the userhas the ability to specify the fusing characteristics as well as take advantage of a lower overall ESR.This fused design allows for capacitors to be Weibull graded per Mil-PRF-55365 as well as surgecurrent tested. TBW fused tantalum capacitors come in standard EIA case sizes C, D and E, anddo not compromise the standard capacitance ratings available in non-fused designs.CAPACITORSApplications:TBW fused tantalum capacitors can beused in any application where applicationguidelines can be exceeded. The mostcommon use of a solid tantalum capacitoris in bypass, coupling, filtering and energystorage.Key Features/Benefits:• Lower ESR specification than competitivefused tantalums• Standard EIA case sizes• Available “lead free” designs as well astin-lead and gold terminations• Variety of fusing characteristics available• Available with COTS+ testing31
