Model C18A50Z4
Surface Mount Termination
18 Watts, 50Ω
Description
The C18A50Z4 is a high performance RoHS compliant Alumina (Al2O3)
surface mount termination intended as a lower cost alternative to
Aluminum Nitride (AIN) and Beryllium Oxide (BeO). The SMD termination
is well suited to all cellular frequency bands such as: AMPS, GSM, DCS,
PCS, PHS and UMTS. The high power handling makes the part ideal for
terminating 90º hybrids, directional couplers, and for use in isolators.

For best thermal performance the PCB should be soldered to
the heat sink.
To ensure good thermal connectivity to heat sink, which is critical for proper
operation drill and tap heatsink and mount PCB to heat sink using screws.
