| HC-49/U-S Miniature Quartz Crystal Unit for Microprocessor Model HC-49/U-S sFeatures Height 3.5mm, the volume is compact at about one-fourth that of the former product (HC-49/U). A resistance weld completely sealed type. The frequency stability is good, the reliability is high. Multiple standard frequencies. Copes with high density mounting and is optimum for mass production models. sSpecifications Type Main application Frequency Range Standard Frequency Overtone Order Operating Temp. Range Storage Temp.
