Vishay introduced the industry’s first surface-mount multilayer ceramic chip capacitors (MLCCs) for high-frequency RF and microwave applications to offer an operating temperature range to +200°C. For telecom base stations and military communication systems, the Vitramon VJ HIFREQ HT series provides ultra high Q and low ESR in four compact case sizes.
For high-power communication transmitters and high-frequency inverters exposed to temperatures of +175°C or higher, designers previously had to rely on MLCCs only qualified to +150°C. With their operating temperature range from -55°C to +200°C, the new devices provide reliable, long term performance in these applications. For increased design flexibility, their small 0402, 0603, 0805 and 1111 case sizes allow for placement close to components with high dissipation, such as SiC and GaN switches.
VJ HIFREQ HT series devices are based on an ultra stable ceramic dielectric and offer a high serial resonant frequency (SRF) and parallel resonant frequency (PRF). The MLCCs feature broad working voltages from 16 V to 500 V and a wide capacitance range from 0,1 pF to 3,3 nF, with tolerance as tight as ±0,05 pF. The devices offer an excellent ageing rate of 0% per decade and high ESD withstand capabilities to protect against high-voltage transients.
