SXT2249DD07-16.000M

Crystals Overview

The SXT2249DD07-16.000M is a 16 MHz fundamental mode AT-cut crystal resonator manufactured by Suntsu Electronics, Inc. It features a frequency tolerance of ±20 ppm and a load capacitance of 9 pF. The equivalent series resistance (ESR) is specified at 100 Ohms. This component utilizes a ceramic package with a 4-SMD, no-lead footprint measuring 2.5 mm x 2.0 mm. It operates within an industrial temperature range of -40°C to +85°C and complies with RoHS standards.

Crystals Feature Summary

• Four-pad surface mount design provides grounding shielding to reduce electromagnetic interference in high-frequency circuits.
• Fundamental AT-cut quartz construction ensures stable oscillation without requiring additional matching inductors.
• Industrial-grade thermal stability maintains frequency accuracy across extended temperature variations.

Crystals Applications

• Bluetooth low energy (BLE) modules
• Short-range wireless communication devices
• PCMCIA cards and modems
• Industrial control systems with dense PCB layouts

Crystals Procurement Notes

Verify the specific suffix '07' against the manufacturer's latest datasheet to confirm the exact load capacitance and temperature grade. Ensure the ordering part number matches the required 9 pF load capacitance specification. Confirm that the 4-SMD no-lead package dimensions align with the target PCB footprint. Check for RoHS compliance documentation if environmental regulations apply to the final assembly.

Crystals Selection Notes

Select this component when space constraints require a 2.5x2.0 mm footprint but EMI performance necessitates a four-terminal ground shield. It is suitable for applications demanding ±20 ppm stability over an industrial temperature range. Consider the 100 Ohm ESR value for oscillator circuit compatibility. Avoid using two-pin variants if radiation emissions are a critical constraint in the design.

Crystals Part Context

This part belongs to the SXT224 series of ceramic surface-mount crystals from Suntsu Electronics. The series offers various frequencies and tolerances within a compact 2520 package. The four-pad configuration distinguishes it from standard two-pin SMD crystals by offering superior noise immunity. It is designed for modern miniaturized electronics where signal integrity is paramount.

Crystals Replacement Considerations

Cross-reference other SXT224 series variants with identical 16 MHz frequency and 9 pF load capacitance. Verify that substitute components maintain the same 4-SMD no-lead package outline and 100 Ohm ESR specifications. Ensure the replacement supports the -40°C to +85°C operating range.
