Crystals Procurement Notes

Verify the specific suffix DC48 against official Suntsu datasheets to confirm the exact temperature range and stability specifications, as distributor listings may vary. Ensure the 4-SMD no-lead footprint matches the target PCB layout. Cross-reference the ESR value of 150 Ohms with circuit requirements. Confirm active status directly with the manufacturer or authorized distributors before ordering.

Crystals Selection Notes

Select this component when a 27.12 MHz frequency is required with ±20 ppm stability. The 8 pF load capacitance must match the host circuit's design. The 150 Ohm ESR should be compatible with the oscillator driver circuit. The wide temperature range makes it suitable for harsh environments compared to commercial-grade alternatives.

Crystals Part Context

This part belongs to the SXT series of surface-mount crystals from Suntsu Electronics. The series typically offers various frequency options and packaging styles. The SXT1148DC48 variant specifically targets applications requiring robust performance in a small form factor, distinguishing it from larger through-hole or standard SMD packages.

Crystals Replacement Considerations

Direct substitutes include other 27.12 MHz crystals with identical 8 pF load capacitance and similar ESR values. Check pin compatibility for 4-SMD no-lead packages. Verify that alternative parts meet the -40°C to +85°C temperature requirement and ±20 ppm stability specification.
