IRC Advanced Film Division
The MWR series is specifically designed for transmission line termination
at high frequencies. Characterized for high frequency performance to 40GHz, the MWR series provides
superior terminator performance to generic “off-the-shelf” chip resistors.
Constructed with IRC’s proprietary TaNFilm
®
self passivating thin film resistive element, the MWR series chips
possess the rugged environmental characteristics proven through decades of the most demanding military,
space, telecommunications, computer, medical and networking applications.
Available with a choice of solderable or bondable termination finishes, the MWR series termination chips are
suitable for solder attachment as well as chip and wire or ribbon attached hybrid circuits. Back side mounting
is facilitated by an optional gold finish.
For demanding microwave/RF transmission line termination applications in harsh environments, select the
IRC MWR series of high frequency termination chips.
