LiBC crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Li1+ is bonded in a 6-coordinate geometry to six equivalent C4- atoms. All Li–C bond lengths are 2.37 Å. B3+ is bonded in a trigonal planar geometry to three equivalent C4- atoms. All B–C bond lengths are 1.59 Å. C4- is bonded in a distorted trigonal planar geometry to six equivalent Li1+ and three equivalent B3+ atoms.
In 2023 AVX developed a new technology of feed-through capacitors that can be used for high (up to GHz range) frequency signal filtering for FPGA, microswitches or micro-DC-DC converters as a replacement for the currently used MLCCs. This part is a Low Inductance Bulk Capacitor (LIBC). It has low ESR and insertion loss values and is manufactured using technology similar to chip polymer tantalum capacitors and have. The purpose of this work is to evaluate the design and performance of the parts using engineering samples from AVX, address potential reliability issues, and suggest screening and lot acceptance procedures necessary to use these capacitors in space projects.
