CX4VHT-TF Datasheet, PDF (1/2 Pages) IQD Frequency Products Ltd – Quartz Crystal Specification
ISSUE 1; January 2016
Description
An increasing number of applications require the use of
high-temperature crystals. For these applications,we offer
CX4VHT crystals. These crystals are designed to operate at
temperatures up to and including 200ºC, and feature an
expected life in excess of 1,000 hours at these temperatures.
The frequency range offered is 30kHz to 250kHz
-SM1 SM1 (gold plated, RoHS compliant)
-SM5 SM5 (Solder dipped, RoHS compliant)
Please note that all data is only valid at 25°C unless otherwise
stated.
