Claim 0:
1. A vibration damping device for use with one or more downhole electronics, the downhole electronics having a longitudinal axis, the vibration damping device comprising:
a device housing mechanically coupled to the downhole electronics, the device housing defining a receptacle having a volume and an inner surface, wherein the downhole electronics comprise a sensor, and wherein the device housing along with the downhole electronics together create a sensor string maintained in a centralized position inside a drill string;
an inertia element movably supported in the receptacle and having a volume, a mass, and a non-zero moment of inertia about the longitudinal axis;
wherein the volume of the receptacle is greater than the volume of the inertia element so as to define an interstitial volume therebetween and wherein the interstitial volume is occupied by a fluid or an elastomer.
