Crystals Procurement Notes

Verify the specific manufacturer datasheet to confirm electrical parameters such as load capacitance and ESR match your circuit design requirements. Ensure the 4-SMD package dimensions align with your PCB footprint. Cross-reference the part number with official distributor catalogs to confirm availability and authenticity from Shenzhen SCTF Electronics or authorized channels before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 25 MHz reference signal is required in a minimal footprint environment. The 12 pF load capacitance must match the external capacitors used in the oscillator circuit to achieve the specified frequency accuracy. Consider the ±10 ppm initial tolerance if tight frequency alignment is critical for synchronization tasks. Evaluate the 30 Ohm ESR against the oscillator amplifier's drive level capabilities to prevent over-driving the crystal.

Crystals Part Context

This part belongs to the SX1B series of surface-mount crystal resonators, characterized by small form factors suitable for modern portable devices. The naming convention typically indicates frequency, load capacitance, and tolerance specifications. Similar parts in the series may offer different frequencies or package sizes, but share the same general construction principles for high-reliability timing applications in digital systems.

Crystals Replacement Considerations

Direct substitutes must maintain the 25 MHz frequency, 12 pF load capacitance, and 2.0x1.6mm package size. Verify that alternative components meet the same ±10 ppm tolerance and ≤30 Ohm ESR specifications to ensure circuit compatibility without redesigning the oscillator network.
