Description:
Thin Film Technology's FL9 series of surface mount low pass filters are designed for use in Duo-Binary modulation
schemes where flat group delay and return loss beyond the cutoff frequency are important characteristics. The discrete
(0.25Ghz) cutoff series of 1/4 bitrates are intended for use in varying bitrates and application requirements including OC-
192(10Gb/s) and forward error correction beyond 12Gb/s.
This product is currently available with solder finishes of Sn63/Pb37, as well as a RoHS compliant / Lead Free solder
finish of Sn95.5/Ag3.8/Cu0.7. For the RoHS compliant / Lead Free part, the customer must specify this upon ordering
by following the instructions in the part numbering section of this specification.
