Measuring 2 x 1.6 x 0.45 mm, the XRCGD crystal is available with nominal operating frequencies from 24 to 48 MHz. Operating temperature is -30 to +85C. Equivalent series resistance (ESR) is in the range of 60 – 22 Ω and is model-dependent. Murata believes it is the first in the industry to adopt a fusion sealing technique for complete hermetic seal that uses an alloy in the metal cap structure. Its proprietary packing technology, unavailable in existing crystal resonators, enables superior quality and cost performance, and is suitable for mass production. At the same time it achieves high density mounting and slimming of the unit.
