PA2-7CB

Free-standing .Beryllium copper clip is designed to provide high clamping pressure, which assures low thermal resistance between dissipator and semiconductor, allowing a 150% power increase in natural convection to more than 400% in forced air. heat dissipator and clip assembly -requires no special tools or mounting hardware. .Clip's spring design firmly attaches to device and dissipator, stays attached even in severe shock and vibration environments. .Clip may be used alone to attach semiconductor to a customer designed heat conduction plane. .Free-standing assembly can be mounted either vertically or horizontally on board PA1-7 DESCRIPTION OF CURVES A.
