Murata's official reason: high voltage machine market is decreasing and they do not earn money from that product range. In fact, we know Murata not only cut the high voltage ceramic capacitor but also quit the general purpose MLCC market in 2017. The basic raw ceramic material for MLCC and hv ceramic disc caps are the same SrTiO3 and BaTiO2 they just invested these resources to more profitable market -Automobile MLCC business. Murata is the world No.1 market share of MLCC, and also world No.1 market share of high voltage ceramic capacitors, a major market in West Europe, USA and most of the Japanese market. HVC understands that Murata's existing customers are urgently seeking for fine replacement hv capacitors with good performance and not changing PCB board. Also, they need component upgrade support to design their new models.
