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.

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.
