4.0 Part Number
These 3042, 1632, and 1220 size chip attenuators exhibit excellent high frequency characteristics. The surface
mount package is ideal for low noise, low inductance and parasitic capacitance applications. Thin film metal-
ization provides for very stable characteristics over temperature and time.
