CVD Diamond Chip Resistor

EMC Technology surface mount (CR) chip resistors with extreme high power ratings may be used in applications from DC to 30 GHz and are ideal for military and space applications because of their high power capability, broad frequency response and small, light-weight size. They are manufactured using all thin film construction and have a thin film gold finish that is both wire bondable and solderable. Because of their total thin film construction they are ideal for peak power applications. The terminal material is thin film, gold solderable or bondable finish. Standard chip and high reliability tested versions based on Mil-PRF-55342 are also available. Select from tape and reel, bulk, or waffle packaging. These products are lead free, RoHS complaint and S-level approved. Standard available values are 50 & 100 ohms. Contact us directly for non-standard resistance values.

Reduce the Size and Weight of Phased Array Radar Feed Network Easily

Corporate-feed networks in phased array radars have benefited from the small footprint, high power handling, and excellent high-frequency characteristics of Diamond Rf resistors. The use of Diamond Rf resistors such as CR0505D, in place of the traditionally larger components, has significantly reduced thsize and weight of the feeder network without compromising power handling and thermal performance.
