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. OUTLINE & DIMENSIONS SPECIFICATION
FEATURES
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 PACKAGING OPTIONS CX11SM crystals are available either tray packed (<250pcs) or tape and reel (>250 pieces). 12mm tape, 178mm or 330mm reels (EIA 418).

Specifications may change without notice. 1. Other load capacitance values are available. 2. The crystal frequency f as a function of temperature T follows the parabolic relationship: f(T)=f(T 0) [1 + k(T T0)2] where T0 is the turnover tmperature na dk is the frequency- temperature constant. 3. Other turnover temperature available. 4. Tighter tolerances available. Drive Level: 0.5µW max.
