Abstract Ancorsteel FLD-49HP is a nickel copper-molybdenum alloy steel powder developed for high-performance sinter-hardening applications. This alloy conforms to MPIF Material standard 35, designation FLDN4C2-4905. The nickel and copper are diffusion-alloyed to the molybdenum pre-alloyed powder during processing to maintain good compressibility while enabling high hardness and toughness in sinter-hardened parts. This datasheet provides information on composition, physical properties, and tensile properties as well as fracture toughness. It also includes information on powder metal forms. Filing Code: SA-809.

Purpose This paper aims to investigate the usability of the nickel copper zinc ferrite with the composition Ni0.4Cu0.2Zn0.4Fe1.98O3.99 for the realization of high-temperature multilayer coils as discrete components and integrated, buried function units in low temperature cofired ceramics (LTCC). Design/methodology/approach LTCC tapes were cast and test components were produced as multilayer coils and as embedded coils in a dielectric tape. Different metallization pastes are compared. The properties of the components were measured at room temperature and higher temperature up to 250°C. The results are compared with simulation data. Findings The silver palladium paste revealed the highest inductance values within the study. The measured characteristics over a frequency range from 1 MHz to 100 MHz agree qualitatively with the measurements obtained from toroidal test samples. The inductance increases with increasing temperature and this influence is lower than 10%. The characteristic of embedded coils is comparable with this of multilayer components. The effective permeability of the ferrite material reaches values around 130. Research limitations/implications The research results based on a limited number of experiments; therefore, the results should be verified considering higher sample sizes. Practical implications The results encourage the further investigation of the material Ni0.4Cu0.2Zn0.4Fe1.98O3.99 for the use as high-temperature ferrite for the design of multilayer coils with an operation frequency in the range of 5-10 MHz and operation temperatures up to 250°C. Originality/value It is demonstrated for the first time, that the material Ni0.4Cu0.2Zn0.4Fe1.98O3.99 is suitable for the realization of high-temperature multilayer coils and embedded coils in LTCC circuit carriers with high performance.
