The HPC0402A/B/C silicon-based surface-mount RF capacitors come in low-profile (0.40 mm, 0.18 mm, and 0.25 mm high for the A, B, and C versions, respectively) 0204-size packages measuring 1.02 by 0.51 mm, with values over 22 pF. Built on a proprietary Vishay Intertechnology process, they boost performance and trim pc-board space by as much as 45%.
The capacitors' innovative design decreases the distances between components placed on a pc board, reducing parasitic inductance to 0.032 nH. Moreover, self-resonant frequency is raised to ultra-high frequencies ranging from 1 MHz to several gigahertz.
The HPC0402A/B/C capacitors come in optional voltage ratings of 6, 10, 16, and 25 V. For the A version, overall capacitance values range from 0.6 up to 180 pF, with tight tolerances within ±1% or 0.05 pF. The B and C versions are available in 16 capacitance ranges from 10 pF to 180 pF with 1% tolerances. Other features include a temperature coefficient of capacitance (TCC) of ±30 ppm/°C and an operating-temperature range of −55°C to 125°C.
The HPC0402A is priced at $0.042 each (1 pF ±0.1 pF) and $0.055 each (180 pF ±5%) for production quantities. The HPC0402B and C capacitors cost $0.055 each in production quantities. Lead times are up to eight weeks.
