RFTS
Features and Applications
High power surface mount termination for all DC up to 6GHz applications.
Small size and wide frequency range specifications realized with through large heat conducting AlN
substrate.
Sufficient mechanical strength metallization from spattered thin film technology.
50ohm and 75ohm resistance with tolerance 1% and 10W, 50W, 100W and 250W provided as
standard, and other resistance and power available.
Long life and temperature stability a result of Ni-Cr thin film technology.
Flanged termination will be available in the RFTF series.
Termination for isolator/circulators, fixed station of mobile communication electronics, and high power
microwave amplifiers.

Derating Curve
(1) Other resistance value and substrate thickness are available.
Please consult Nikkohm factory.
(2) Power rating assumes that chip attached on metal insulated PC
board.
(3) Solder joint design should assure a solder thickness within 50
micron meters.
