DESCRIPTION

The 'HT' range of crystals are designed for applications subjected to

high operating temperatures. The CX1HT, CX4HT and CX9HT crystals

operate up to 200°C and feature an expected life in excess of 1000

hours at these temperatures. The frequency range is:

CX1HT: 8.0MHz to 250MHz

CX4VHT: 14MHz to 250MHz

CX9VHT: 14MHz to 250MHz.
