VISHAY Intertechnology Inc., represented in Australia by Soanar , has released new surface-mount chip resistor attenuators capable of replacing three or more discrete components, in turn reducing board space requirements and simplifying manufacture of smaller, lighter electronic systems.
Intended for RF signal attenuation applications in telecom and mobile wireless products, the new Vishay Dale CZA04S and CZA06S reduce component count while improving performance with tolerance matching and temperature tracking superior to that provided by individual components.
The CZA04S features a power rating of 0.040W and impedance of 50Ω, while the CZA06S features a power rating 0.075W with impedance values of 50Ω, 75Ω, 100Ω, 300Ω, and 600Ω.
Both devices offer attenuation ranges and tolerance values of 1dB to 5dB at 0.3dB (L) and 6dB to 20dB at 0.5dB (H). The frequency range for both the CZA04S and CZA06S is dc to 3GHz.
The space-saving dimensions of the CZA04S are 1.00mm x 1.00mm with a height profile of 0.36mm. The CZA06S measures 1.60mm x 1.50mm with a height profile of 0.51mm.
Operating temperature ranges for the new CZA attenuator solutions are 55°C to +125°C for the CZA04S and 55°C to +150° for the CZA06S.
Both tin/lead (Sn/Pb) and RoHS-compliant, lead (Pb)-free versions of the new devices are available. Extended values, non-standard tolerances, impedance matching, and other attenuation values are available upon request.
