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.

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(T⁰) [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.
