Non-reflective Terminations (Box Type)
N, BNC-TM Series
1.High Performance
These super wide bandwidth/ultra high matching non-
reflective termination use Hirose Electric original high
frequency matching technology.
2.Heat Sink Equipped Type
The usable power has been increased to 30 W through
the use of a heat sink. (5 W without heat sink)
