EURO QUARTZ CX9VSM CRYSTAL Ultra-Miniature Low-Profile SMD Crystal FEATURES 32kHz to 160kHz OUTLINE & DIMENSIONS Frequency Range 32kHz to 160kHz High shock resistance Ultra-small ceramic package Low ageing Designed for low power applications Full MIL testing available DESCRIPTION CX9VSM crystals are leadless devices designed for surface mounting on PCBs or hybrid substrates. The crystals have a very low-profile (<0.94mm) and are suited for all low frequency applications. SPECIFICATION Specifications stated are typical at 25°C unless otherwise indicated. Specifications may change without notice.
