402F4801XIJT

Crystals Overview

The CTS-Frequency Controls 402F4801XIJT is a 48 MHz fundamental mode crystal oscillator designed for surface mount applications. It features a frequency tolerance of ±10ppm and an equivalent series resistance (ESR) of 60 Ohms. The component operates within a temperature range of -40°C to +85°C and utilizes a load capacitance of 9pF. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.00mm x 1.60mm.

Crystals Feature Summary

• Fundamental mode operation for stable frequency generation
• Compact 4-SMD no-lead surface mount packaging
• Wide industrial operating temperature range capability

Crystals Applications

• Clock signal generation for microprocessors
• Timing references for communication interfaces
• Frequency control in consumer electronic devices

Crystals Procurement Notes

Verify the specific suffix 'IJT' against the manufacturer's current datasheet to confirm tape and reel packaging specifications. Ensure that the load capacitance requirement of the target circuit matches the 9pF specification to maintain frequency accuracy. Cross-reference the ESR value of 60 Ohms with the oscillator circuit design parameters.

Crystals Selection Notes

Select this component when a 48 MHz reference with ±10ppm stability is required in a small form factor. The 4-SMD no-lead package suits automated assembly processes. Consider the -40°C to +85°C temperature range for industrial or automotive environments where standard commercial ranges are insufficient.

Crystals Part Context

This part belongs to the 402F series of surface mount crystals from CTS-Frequency Controls. The series offers various frequencies and package sizes optimized for space-constrained designs. The 402F series is widely used in portable electronics and embedded systems requiring reliable timing solutions.

Crystals Replacement Considerations

The 402F4801XIAR is a similar variant with a 10pF load capacitance instead of 9pF. Verify if the circuit design can accommodate the slight difference in load capacitance before substituting.
