Malvern, Pa. Vishay Intertechnology, Inc. has developed a new series of surface-mount chip resistor attenuators that can replace three or more discrete components, which will help designers reduce component count and save board space in their new electronic system designs.
Designed for RF signal attenuation applications in telecommunications and mobile wireless products, the new Vishay Dale CZA04S and CZA06S devices are also said to improve performance with better tolerance matching and temperature tracking than what's provided by discrete components.
The CZA04S features a power rating of 0.040 W and impedance of 50 Ω while the CZA06S features a power rating 0.075 W with impedance values of 50 Ω, 75 Ω, 100 Ω, 300 Ω, and 600 Ω. Both devices offer attenuation ranges and tolerance values of 1 dB to 5 dB at 0.3 dB (L) and 6 dB to 20 dB at 0.5 dB (H). The frequency range for both the CZA04S and CZA06S is DC to 3 GHz.
The CZA04S measures 0.039 x 0.039 in. (1.00 x 1.00 mm) with a height profile of 0.014 in. (0.36 mm), while the CZA06S offers dimensions of 0.063 x 0.059 in. (1.60 mm x 1.50 mm) with a height profile of 0.020 in. (0.51 mm). The operating temperature range for the CZA04S is -55°C to 125°C and -55°C to 150° for the CZA06S.
The new CZA devices are available in tin/lead (Sn/Pb) and RoHS-compliant, lead-free versions. Extended values, non-standard tolerances, impedance matching, and other attenuation values are available on request.
Pricing for the CZA devices starts at $0.028 each in quantities of 25,000 or more for U.S. delivery. Samples and production quantities are available now, with a lead time of 10 weeks for larger orders.
