Capacitors Claimed As Industry’s Thinnest

Touted as the industry’s first silicon-based capacitors optimized for smart card applications, two new devices claim to set a new standard for high capacitance in a compact package. The HPC0402B and HPC0402C high-precision capacitors are said to operate at higher frequencies with higher performance than conventional low-profile capacitors. Developed in 16 capacitance options ranging from 10 pF to 180 pF with tight tolerances up to ±1%, the HPC0402B and HPC0402C are rated for 6V, 10V, 16V and 25V operation. Both capacitors have highly accurate dimensions, measuring 1.02 mm x 0.51 mm, with height profiles of 0.18 mm for the B model and 0.25 mm for the C model. High capacitance and a small size result in a greater circuit Q and longer transmission range. Since a smaller capacitor is less likely to be delaminated due to flexation stresses, smart card reliability is improved, the company says. Both the HPC0402B and HPC0402C have been designed in surface-mount or wire-bondable configurations. VISHAY INTERTECHNOLOGY INC., Malvern, PA. (610) 644-1300.
