Knowles extends HiT high temperature MLCC range

Knowles capacitor brands Novacap and Syfer Technology have jointly announced a significant extension to their MLC chip capacitor product offering.

Knowles Capacitors' HiT range of MLCCs has an operating temperature range of -55 to +200ºC and will now be offering tin over nickel terminations not previously available in the company’s other high temperature MLCC ranges.

Launch specifications encompass both Stable (C0G) and ultra stable (X7R) dielectric options in case sizes 0805 to 2220, with a capacitance spread of 4.7pF to 3.3uF and rated voltages of 16 to 630V dc.An increase in specified max capacitor values for the 500/630V parts – with an upper limit now of 68nF – and the addition of an 0603 case size in X7R material will be announced shortly, according to Knowles.

This range is both RoSH compliant and lead free and is manufactured using a screen printing process unique to Knowles. The extended range is expected to be suitable for use in oil exploration, geothermal, military, automotive under-hood and avionic applications..
