402WF20015HKR

Crystals Overview

The 402WF20015HKR is a surface-mount quartz crystal oscillator manufactured by CTS-Frequency Controls. It operates at a nominal frequency of 20 MHz with a frequency tolerance of ±10 ppm and stability of ±20 ppm. The component features an 8 pF load capacitance and an equivalent series resistance (ESR) of 100 Ohms. Designed for fundamental mode operation, it utilizes a 4-SMD, no-lead package measuring 2.0 mm x 1.6 mm x 0.55 mm. It supports a drive level of 10 µW and functions within a temperature range of -40°C to +85°C.

Crystals Feature Summary

• Sub-miniature surface-mount design optimized for space-constrained applications
• Enhanced frequency stability suitable for IoT and high-reliability systems
• Fundamental mode quartz construction for precise timing control

Crystals Applications

• Internet of Things (IoT) devices requiring compact timing solutions
• High-frequency digital circuits needing stable clock references
• Portable electronic equipment with strict size limitations

Crystals Procurement Notes

Verify the specific suffix HKR against official CTS documentation to confirm package and tape specifications. Ensure compatibility with reflow soldering profiles defined in the manufacturer datasheet. Confirm that the 8 pF load capacitance matches the target circuit design requirements before integration.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency with tight ±10 ppm tolerance is required in a 2.0x1.6 mm footprint. Consider the 100 Ohm ESR and 10 µW drive level constraints for oscillator circuit design. Evaluate thermal performance within the -40°C to +85°C range against application environmental conditions.

Crystals Part Context

This part belongs to the 402W series of sub-miniature surface-mount crystals from CTS-Frequency Controls. The series is characterized by small physical dimensions and enhanced performance metrics compared to standard 402 series components, targeting modern electronics where board space is limited.

Crystals Replacement Considerations

Direct substitutes include other 402W series variants with identical electrical parameters. Verify package dimensions and pin configuration compatibility when considering alternative frequencies or tolerances from the same manufacturer family.
