• WiFi-enabled consumer electronics

Crystals Procurement Notes

Verify the specific suffix codes against the manufacturer's official naming convention to ensure accurate frequency tolerance and temperature range selection. Confirm that the required load capacitance matches the circuit design specifications. Check for lead-free status compliance if environmental regulations apply to the target assembly process. Ensure storage conditions adhere to moisture sensitivity level requirements prior to soldering.

Crystals Selection Notes

Select this component when space constraints require a footprint smaller than standard 0402 resistors. The four-pad design offers superior noise immunity compared to two-pad alternatives of similar dimensions. Consider the -20°C to +70°C operating range for indoor consumer electronics rather than harsh industrial environments requiring wider thermal margins. Validate ESR limits against the oscillator circuit's drive level requirements to prevent overdriving or startup failures.

Crystals Part Context

This part belongs to the SXT114 series of ultra-small crystals from Suntsu Electronics. The series covers frequencies from 24 MHz to 54 MHz, targeting Bluetooth and WiFi bands. The 'C' indicates ±25 ppm tolerance, 'A' denotes the specific stability grade, and '27' specifies the -20°C to +70°C temperature range. These components are engineered for portable devices where miniaturization and signal integrity are critical design priorities.

Crystals Replacement Considerations

Direct substitutes must match the 1.6 x 1.2 mm 4-pad form factor and 24 MHz frequency. Verify equivalent load capacitance and ESR values to maintain circuit stability. Cross-reference temperature ranges and tolerance grades to ensure functional parity in the final application environment.
