32.768 kHz Crystal KX-327NHT with innovative improvement

With the model name KX-327NHF is now
available with an extended temperature
range of -40°C ~ +125°C for Automotive
applications. AECQ 200 qualified.


The KX-327NHT is a precise and a high-
performance Clock crystal and available with
a series resonance of only 50k Ohm max.
This innovative improvement offers secure
oscillation, a shorter start-up time, and higher
Trim Sensitivity, thereby saving power. The working temperature range extends
from -40 to +85°C.
The Chipset series 8, from Manufacturer Intel, states a need to only use a
Crystal with a maximum ESR of 50k Ohm.
