402F480XXCKR

Crystals Overview

The CTS-Frequency Controls 402F480XXCKR is a 48 MHz fundamental mode quartz crystal resonator designed for surface mount applications. It features a frequency stability of ±15 ppm and an equivalent series resistance (ESR) of 60 Ohms maximum. The component operates with a load capacitance of 8 pF and is housed in a compact 4-SMD, No Lead package measuring 1.60mm x 1.20mm x 0.45mm. It supports a standard operating temperature range of -20°C to +70°C.

Crystals Feature Summary

• Fundamental mode operation at 48 MHz
• Compact 4-SMD no-lead surface mount footprint
• Low equivalent series resistance of 60 Ohms
• Standard commercial temperature range support

Crystals Applications

• General purpose clock generation circuits
• Microcontroller system timing references
• Communication module oscillator circuits
• Consumer electronics timing control

Crystals Procurement Notes

Verify the specific load capacitance requirement of 8pF against the target circuit design to ensure accurate oscillation frequency. Confirm that the 4-SMD no-lead package dimensions align with the PCB land pattern specifications. Ensure the operating environment remains within the specified -20°C to +70°C range for guaranteed performance stability.

Crystals Selection Notes

Select this component when a fundamental mode crystal with low ESR is required for space-constrained designs. The 8pF load capacitance suits circuits with lower parasitic capacitance compared to 12pF or 18pF variants. Consider the ±15ppm stability limit for applications not requiring high-precision industrial grade timing sources.

Crystals Part Context

This part belongs to the CTS 402 series of surface mount crystals. It shares the same 48 MHz frequency and package style as other variants like the 402F480XXCJR but differs in load capacitance specifications. The series provides fundamental mode options across various frequencies up to 64 MHz.

Crystals Replacement Considerations

The 402F480XXCJR serves as a parameter-equivalent alternative from the same manufacturer, differing primarily in its 9pF load capacitance specification. Verify circuit compatibility regarding load capacitance changes before substitution.
