402F5401XILR

Crystals Overview

The CTS-Frequency Controls 402F5401XILR is a fundamental parallel quartz crystal resonator designed for surface-mount applications. It operates at a nominal frequency of 54 MHz with a frequency tolerance and stability of ±10 ppm. The component features a load capacitance of 12 pF and an equivalent series resistance (ESR) of 60 Ohms. It utilizes a hermetic ceramic package in a 4-SMD, no-lead configuration with dimensions of 2.00 mm x 1.60 mm x 0.55 mm. The device supports a wide operating temperature range from -40°C to +85°C and complies with RoHS3 standards.

Crystals Procurement Notes

Verify the specific suffix 'LR' corresponds to tape-and-reel packaging requirements. Confirm that the ±10 ppm tolerance meets system timing accuracy needs. Ensure the 12 pF load capacitance matches the host circuit design. Check current availability status as distribution channels may vary.

Crystals Selection Notes

Select this component when a 54 MHz fundamental crystal with high stability is required. The 60 Ohm ESR must be compatible with the oscillator circuit drive level. Consider the 4-SMD package size constraints during PCB layout. Verify thermal performance within the specified -40°C to +85°C range for the target environment.

Crystals Part Context

This part belongs to the CTS 402 Series, which specializes in sub-miniature surface-mount crystals. The series covers frequencies from 16 MHz to 96 MHz. The 402F5401XILR represents a standard frequency option within this lineup, offering a balance between size and electrical performance for modern compact electronics.

Crystals Replacement Considerations

Direct substitutes include 402F5401XIAR and 402F5401XILR variants from CTS-Frequency Controls. Parameter-equivalent options may include other manufacturers' 54 MHz crystals with matching 12 pF load capacitance and similar ESR values. Verify package compatibility before substitution.
