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. OUTLINE & DIMENSIONS SPECIFICATION
FEATURES
Frequency Range 32kHz to 160kHz High shock resistance Ultra-small ceramic package Low ageing Designed for low power applications Full MIL testing available PACKAGING OPTIONS CX9VSM crystals are available either tray packed (<250pcs) or tape and reel (>250 pieces). 16mm tape, 178mm or 330mm reels (EIA 418).
