Abstract : Retesting of 1 MHz, 100 C loss tangent has confirmed the value to be between 6.6 and .000127 which is higher than anticipated. Although data are incomplete, it has been suggested that a peak relationship between loss tangent and frequency exists. The peak position just below 1 MHz shifts higher with increasing temperature. Such a relationship is common for certain other dipolar dielectrics. (Author)
