■Mounting Method
●Do not leave a space between the terminator and
the microstrip board.
●Make the terminator tab height from the housing and
the thickness of the microstrip board the same
amount.
●Note: The HT-025-1 type is attached with high
temperature solder (having a melting point of 280ç).
The soldering temperature to the microstrip board
must be less than this.
HT-025-1
●Mounting is performed by soldering over the
microstrip line pattern.
●The mounting should be completed by soldering
within 5 seconds using Sn-Pb type eutectic solder
containing 2 to 5% Ag with a soldering iron adjusted
to about 260ç.
●The resoldering of an item that has already been
soldered once and then removed is not effective
since solder cracks will develop at the electrode
portion.
HT-05-2
●Do not leave a space between the terminator and
the microstrip board.
●Do not leave a space between the the microstrip
board.
●Note: The HT-1-1, HT-1-2, HT-1-3, HT-10-2, HT-203, and HT-50-1 tabs are attached with high
temperature solder (having a melting point of 280ç).
The soldering temperature to the microstrip board
must be less than this.
Note: Although the high frequency characteristics will
deteriorate somewhat, please attach with some slack
in the tabs in order to raise the thermal reliability.

Terminations for the Division Part of a Wilkinson Divider (100 ohms Type)
HT Series
■Features
1.High Performance
These wide bandwidth/ultra high matching nonreflective termination use Hirose Electric original
high frequency matching technology.
2.Equipped with Tabs
Termination are equipped with tabs to permit direct
mounting to Wilkinson type flat circuits.
3.High Power and Small Size
Beryllia is used for the material of the resistance
element to enable the termination to be of small
size and used with high power.
