VISHAY'S NEW CHIP RESISTOR ATTENUATORS WITH 0.040 W AND 0.075 W POWER RATINGS
27 April 2006 - Vishay Electronic

Vishay Intertechnology, Inc. today announced the release of 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 0.040 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 announced today 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 space-saving dimensions of the CZA04S are 0.039 in. by 0.039 in. [1.00 mm by 1.00 mm] with a height profile of 0.014 in. [0.36 mm]. The CZA06S measures 0.063 in. by 0.059 in. [1.60 mm by 1.50 mm] with a height profile of 0.020 in. [0.51 mm]. Operating temperature ranges for the new CZA attenuator solutions are -55 °C to +125 °C for the CZA04S and -55 °C to +150 °C 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.

Samples and production quantities of the new CZA surface-mount chip resistor attenuators are available now, with a lead time of 10 weeks for larger orders.
