Crystals Procurement Notes

Verify the specific ordering suffix to confirm packaging type, such as tape and reel or cut tape, as this affects handling procedures. Ensure the requested quantity matches the standard reel size if bulk procurement is required. Cross-reference the manufacturer's latest datasheet to confirm current availability and any potential obsolescence notices before finalizing orders.

Crystals Selection Notes

Select this component when a 27.12 MHz reference signal is required for wireless protocols. The 10 pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR for power consumption constraints. The wide temperature range makes it suitable for automotive or outdoor applications where thermal stability is critical for frequency accuracy.

Crystals Part Context

This part belongs to the TZ series of crystal resonators manufactured by TST (Tai-Saw Technology Inc.). The series is specifically engineered for RF and timing applications in consumer electronics and telecommunications. These components utilize quartz technology to provide precise frequency control for synchronization in digital circuits.

Crystals Replacement Considerations

Direct substitutes must match the 27.12 MHz frequency, 10 pF load capacitance, 60 Ohm ESR, and 2.0x1.6mm footprint. Verify that alternative manufacturers offer the same ±10 ppm tolerance and -40°C to +85°C operating range to ensure circuit compatibility.
