SXT22420BB16-50.000M

Crystals Overview

The SXT22420BB16-50.000M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc., designed for precision timing applications. It operates at a fundamental frequency of 50.000 MHz with a load capacitance of 20 pF and an equivalent series resistance (ESR) of 50 Ohms. The component features a frequency tolerance of ±30 ppm and supports an operating temperature range from -10°C to +60°C. Packaged in a compact 4-SMD, no-lead form factor, it utilizes AT-cut technology for stable performance in wireless and industrial control systems.

Crystals Feature Summary

• Four-pad ceramic SMD design provides enhanced grounding and shielding compared to standard two-pin packages.
• AT-cut fundamental mode operation simplifies circuit design without requiring additional matching inductors.
• High insulation resistance ensures reliability in industrial-grade environments.

Crystals Applications

• Bluetooth low energy (BLE) devices
• Short-range wireless communication equipment
• Industrial control systems with high-density board layouts

Crystals Procurement Notes

Verify the specific suffix '16' against official Suntsu documentation to confirm the exact temperature range and tolerance specifications. Ensure the required load capacitance matches the target circuit design. Confirm package dimensions align with PCB footprint requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when space constraints require a 2.5x2.0 mm footprint but electromagnetic interference mitigation is critical. The four-terminal configuration offers superior noise immunity for 2.4 GHz RF sections compared to two-terminal alternatives. Consider the ±30 ppm stability sufficient for general wireless protocols while ensuring the -10°C to +60°C range meets environmental operational needs.

Crystals Part Context

This part belongs to the SXT224 series of industrial-grade ceramic surface-mount crystals. The series is characterized by small form factors suitable for portable and wearable electronics. Variants within the series differ primarily in frequency, tolerance, and temperature range, sharing common mechanical and electrical interface standards.

Crystals Replacement Considerations

Direct substitutes must match the 50 MHz frequency, 20 pF load capacitance, and 4-SMD package. Verify that alternative components support similar ESR values and offer comparable thermal stability ranges to maintain system timing integrity.
