Description:
This specification applies to a generalized family of passive element networks performing equalization. These networks
compensate the loss in high speed data transmission media. This component is a 0603 package with an 0402 footprint
intended for SMT assembly. This series covers application data rates of 2.5, 3.125, 5.0, 6.25, 10.0, 12.5 Gb/s, for Bessel
function losses of 3, 6, 9, 12 dB.
Applications include high speed cables, backplanes, test equipment, and optical
modules. Custom precision equalization for other loss functions are available.
This product is currently only available with an electrode finish of gold (Au) over Nickel (Ni). This product is fully RoHS
compliant.

Mounting Recommendation:
Assembly Considerations:
Type 3 solder paste, use 0.005 inch stencil thickness.
Nitrogen purge is recommended during solder reflow.
This is a Pb-free part. Both Sn-Pb eutectic and Pb-free profiles are shown.
This is a recommendation based on third party testing. Each end user should test and determine their own optimum
conditions.
