402F54012IKT

Crystals Overview

The CTS-Frequency Controls 402F54012IKT is a fundamental mode quartz crystal resonator designed for surface-mount applications. It operates at a nominal frequency of 54 MHz with a frequency tolerance of ±10 ppm and a frequency stability of ±20 ppm. The component features an 8 pF load capacitance and an equivalent series resistance (ESR) of 60 Ohms. It utilizes a 4-SMD, No Lead package with dimensions of 1.60mm x 1.20mm x 0.45mm maximum height. The device supports a wide operating temperature range from -40°C to +85°C and is compliant with RoHS3 standards.

Crystals Feature Summary

• Fundamental mode quartz crystal operation for precise timing
• Compact 4-SMD no-lead surface mount package design
• Wide industrial temperature range capability
• RoHS3 compliant construction

Crystals Applications

• Timing circuits requiring stable 54 MHz reference
• Low-power signal processing designs
• Consumer electronics with space constraints

Crystals Procurement Notes

Verify the specific suffix 'IKT' against the manufacturer's current datasheet to confirm packaging and availability status. Cross-reference the exact load capacitance and ESR values required by the target circuit design. Ensure the 4-SMD footprint matches the PCB layout specifications. Check for any recent obsolescence notices or lifecycle changes directly from CTS-Frequency Controls before finalizing procurement plans.

Crystals Selection Notes

Select this component when a 54 MHz fundamental mode crystal is required in a compact SMD form factor. The 8 pF load capacitance must match the oscillator circuit's external capacitors. Verify that the ±10 ppm tolerance meets the system's frequency accuracy requirements. Consider the -40°C to +85°C temperature range for environmental suitability. Confirm the 60 Ohm ESR is compatible with the driving circuit's power limits.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. It shares the same physical footprint and electrical characteristics as other variants in the series with different frequencies or tolerances. The 'I' suffix typically indicates a specific tape and reel packaging configuration. It is distinct from the 416 series which may have different dimensional or performance profiles.

Crystals Replacement Considerations

Direct substitutes include 402F54012IAR and 402F54012ITR from CTS-Frequency Controls, which share identical electrical parameters. Verify that the alternative suffixes do not introduce differences in packaging or moisture sensitivity levels. Ensure any cross-brand replacement maintains the 54 MHz frequency, 8 pF load capacitance, and 4-SMD package dimensions.
