Construction:
 High Purity Alumina Substrate
 Ni alloy thin-film resistive elements
 Wrap around electrodes
 100% matte tin over Ni terminations
(RoHS compliant and Pb Free)
Features:
 0402, 0404, 0603, 0805, 1206 and 1712
English case sizes
 Attenuation values between 0-20dB
 50Ω impedance (75Ω also available in
1712 size)

commercial and special applications
Description:
These precision chip attenuators exhibit excellent high frequency characteristics. The surface mount package is ideal
for applications requiring low noise, low inductance and low parasitic capacitance. The thin film metallization provides
for very stable characteristics over temperature and time.
