EURO QUARTZ CX11SM CRYSTAL 32.768kHz, 100kHz to 180kHz Ultra-Miniature SMD Crystal FEATURES OUTLINE & DIMENSIONS Frequency Range 32.768kHz and 100kHz to 180kHz High shock resistance Ultra-small ceramic package Low ageing Designed for low power applications Full MIL testing available DESCRIPTION CX11SM crystals are leadless devices designed for surface mounting on PCBs or hybrid substrates. The crystals have very small outline and low-profile and are suited for all low frequency applications. SPECIFICATION Specifications stated are typical at 25°C unless otherwise indicated. Specifications may change without notice.
