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)
