Non-magnetic surface-mount MLCCs from 6.3 VDC to 3000 VDC
Vishay’s VJ series devices feature a wet build process and a reliable Noble Metal Electrode (NME) system. This new non-magnetic series of capacitors can be assembled in an SMT process using conductive epoxy bonding or IR reflow. The capacitors are proven to have less interference than standard capacitors, which contain magnetic materials. The devices will typically be used in filter circuits for MRI equipment, implantable medical devices, ferromagnetic-sensitive instrumentation, electronic test systems, and high-end audio amplifiers. Offered in 11 case sizes from 0402 to 3640, the VJ series features high voltage ranges from 6.3 VDC to 3000 VDC. The devices offer a wide capacitance range of 0.5 pF to 56 nF (with C0G dielectric) and 100 pF to 6.8 μF (with X7R/X5R dielectric), and an operating temperature range of – 55°C to + 125°C. The capacitors provide a temperature coefficient of capacitance (TCC) of ± 30 ppm/°C from – 55 °C to + 125 °C (C0G), ± 15 % from – 55 °C to + 85 °C (X5R), and ± 15 % from – 55 °C to + 125 °C (X7R). The devices are compliant to RoHS Directive 2002/95/EC and halogen-free according to the IEC 61249-2-21 definition.
