SXT22419DB38-22.1184M

Crystals Overview

The SXT22419DB38-22.1184M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc., operating at a fundamental frequency of 22.1184 MHz. It features a frequency stability of ±30 ppm and a load capacitance of 19 pF. The device utilizes an AT-cut resonator with an equivalent series resistance (ESR) of 80 Ohms maximum. Packaged in a compact 4-SMD, no-lead form factor measuring 2.5 mm by 2.0 mm, it supports industrial temperature ranges from -30°C to +85°C. This component is designed for precision timing applications requiring stable oscillation within small footprints.

Crystals Feature Summary

• Utilizes a standard 4-pad ceramic SMD package design that provides enhanced grounding and shielding capabilities compared to 2-pin alternatives, reducing electromagnetic interference in high-frequency circuits.

Crystals Applications

• Bluetooth low energy devices
• Short-range wireless communication systems
• Industrial control equipment with dense board layouts

Crystals Procurement Notes

Verify the specific suffix codes against official datasheets to ensure correct load capacitance and tolerance specifications. Confirm that the 4-SMD package dimensions align with PCB footprint requirements. Check for any manufacturing date codes or lot traceability requirements relevant to industrial compliance standards before finalizing orders.

Crystals Selection Notes

Select this component when space constraints require a 2.5x2.0 mm footprint but EMI performance remains critical. The 4-pad configuration offers superior noise immunity compared to 2-pin variants. Ensure the circuit design accommodates the 19 pF load capacitance and 80 Ohm ESR limits for reliable startup across the specified industrial temperature range.

Crystals Part Context

This part belongs to the SXT224 series of industrial-grade crystals from Suntsu Electronics. The series is characterized by its small 2520 package size and robust construction suitable for demanding environments. It serves as a timing reference for microcontrollers and RF transceivers where size and reliability are prioritized over cost-sensitive consumer applications.

Crystals Replacement Considerations

Direct substitutes include other 22.1184 MHz crystals with identical 19 pF load capacitance and 4-SMD no-lead packaging. Verify that alternative parts match the 80 Ohm ESR limit and ±30 ppm stability requirement to maintain system timing accuracy without redesigning the matching network.
