SXT2249DC07-20.000M

Crystals Overview

The SXT2249DC07-20.000M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc., operating at a nominal frequency of 20.000 MHz. It features a standard 4-SMD, no-lead package with dimensions of 2.5mm x 2.0mm. The component exhibits a normal temperature frequency tolerance of ±20ppm and a load capacitance of 9pF. Its equivalent series resistance (ESR) is specified at 80 Ohms. The device is designed for commercial applications within an operating temperature range of 0°C to +70°C.

Crystals Feature Summary

• Four-pad surface mount design provides grounding capability for improved electromagnetic interference shielding compared to two-pin variants.
• AT-cut fundamental resonance mode ensures stable oscillation without requiring additional matching inductors.
• Compact 2.5mm x 2.0mm footprint supports high-density circuit board layouts.

Crystals Applications

• Bluetooth low energy (BLE) communication modules
• Short-range wireless devices
• PCMCIA interfaces
• Industrial control systems

Crystals Procurement Notes

Verify the specific suffix DC07 against the official datasheet to confirm the 0°C to +70°C commercial temperature rating and ±20ppm tolerance. Ensure the ordering information matches the required 9pF load capacitance and 80 Ohm ESR specifications for the target application circuit design.

Crystals Selection Notes

Select this component when a compact 2520 package is required for RF sections sensitive to electromagnetic interference. The four-terminal structure offers superior shielding compared to two-terminal alternatives. Confirm that the commercial temperature range meets the environmental requirements of the end product.

Crystals Part Context

This part belongs to the SXT224 series of ceramic surface-mount crystals from Suntsu Electronics. The series utilizes AT-cut quartz resonators housed in small form-factor packages. The SXT224 line is engineered for wireless and industrial applications requiring stable frequency generation in space-constrained designs.

Crystals Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 20MHz frequency, 9pF load capacitance, 80 Ohm ESR, and 2.5x2.0mm package dimensions.
