445W31D24M57600

Crystals Overview

The CTS-Frequency Controls 445W31D24M57600 is a passive quartz crystal resonator designed for surface-mount applications. It operates at a fundamental frequency of 24.576 MHz with a frequency tolerance and stability of ±30 ppm. The component features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 40 Ohms. It utilizes a glass-sealed construction within a 2-SMD, no-lead package measuring 5.0 mm in length, 3.2 mm in width, and 1.35 mm in height. The device supports a maximum drive level of 100 µW and functions reliably across an operating temperature range of 0°C to +50°C.

Crystals Procurement Notes

Verify the specific suffix 'D' against official CTS documentation to confirm the exact load capacitance and temperature range specifications. Ensure that the required 18 pF load capacitance matches the target circuit design. Confirm compliance with RoHS standards and check for any specific moisture sensitivity level requirements before integration into the production workflow.

Crystals Selection Notes

Select this component when a 24.576 MHz reference is required with ±30 ppm stability. The 18 pF load capacitance must align with the oscillator circuit's external capacitor values. Consider the 0°C to +50°C operating range for industrial or commercial environments. The 40 Ohm ESR should be compatible with the driving gate's capability to sustain oscillation without excessive power dissipation.

Crystals Part Context

This part belongs to the CTS 445 Series of glass-sealed crystals. The series is characterized by high reliability and consistent performance in surface-mount formats. The 445W31D variant specifically denotes the 24.576 MHz frequency point with defined electrical parameters for general-purpose timing applications.

Crystals Replacement Considerations

Direct substitutes within the same series include parts with identical frequency and package dimensions but potentially different load capacitances or temperature ranges. Verify compatibility of the new part's load capacitance and ESR with the existing oscillator circuit to ensure stable operation.
