TaNFilm® Microwave Chip Resistor IRC Advanced Film Division MWR Series • • • • • Long life self passivating TaNFilm® element Low absolute TCR to ±25ppm/°C Performance characterized to 40GHz Wire-bonded, ribbon-bonded or solder mounted Flip chip mounting – keeps resistor element in the same plane as circuit 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.
