multi-layer ceramic chip capacitors

Vishay Intertechnology recently unveiled its latest multi-layer ceramic chip capacitors in the VJ Safety series. Vishay's new chip capacitors are offered with C0G (NP0) and X7R dielectrics and provide X1/Y2 and X2 safety classifications and 250VAC voltage ratings. The devices are also optimised for EMI and AC line filtering and are also equipped for lightning-strike and voltage protection in power supplies, battery chargers, and isolators for fax machines, telephones, modems, routers, and AC equipment and appliances.

VJ Safety capacitors with a C0G (NP0) dielectric cover a capacitance range of 10pF to 1.0nF, with a temperature coefficient of capacitance (TCC) of 0 ppm/°C ±30ppm/°C from -55°C to 125°C and an ageing rate of 0 per cent maximum per decade. If higher capacitance values are needed, X7R devices provide capacitance to 12nF, TCC of ±15 per cent from -55°C to 125°C with 0VDC applied, and an ageing rate of 1 per cent maximum per decade. Capacitors with X1/Y2 and X2 safety classifications handle peak impulse voltages of 5000V and 2500V, respectively.

Packaging options for the devices include 2008, 2012, and 2220 case sizes with low profiles. Datasheets for Vishay's multi-layer ceramic chip capacitors can be found below:
