(GSFT). The Flexiterm® is a surface mountable automo-
tive qualified termination that adds an extra margin
against damage due to flexture during installation.
The 504L Series has been designed with high quality
selected materials that yield excellent performance.
It can be supplied as either frequency compensated
or non-compensated. This product is ideal for use in
Optical Transceiver Modules or any application
requiring excellent ultra-broadband performance.

ATC accepts orders for our parts using designations
with
or
without
the “ATC” prefix. Both
methods of defining the part number are equivalent, i.e., part numbers referenced with the
“ATC” prefix are interchangeable to parts referenced without the “ATC” prefix. Customers are
free to use either in specifying or procuring parts from American Technical Ceramics.
