MALVERN, PENNSYLVANIA — Vishay
Intertechnology, Inc. 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.
(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.
production quantities of the new CZA surface-mount chip resistor attenuators are available now, with a lead time of
10 weeks for larger orders.
