Crystals Procurement Notes

Verify the specific suffix 'H' indicates the 32 pF load capacitance configuration against the official datasheet. Confirm the 0°C to +50°C operating temperature range meets application requirements. Ensure the 2-SMD footprint matches the PCB layout. Cross-reference the manufacturer's latest documentation for any updates to the 445 series specifications before finalizing procurement.

Crystals Selection Notes

Select this component when a 12 MHz fundamental frequency with 32 pF load capacitance is required. The 445W23H variant is suitable for applications requiring ±20 ppm tolerance. Consider the 0°C to +50°C temperature range limitations compared to industrial grade options. Verify the 40 Ohm ESR aligns with the oscillator circuit design constraints for stable startup.

Crystals Part Context

This component belongs to the 445 series of SMD crystals from CTS-Frequency Controls. The series provides various load capacitance options, with the 'H' suffix denoting 32 pF. It shares the standard 5.0 x 3.2 mm footprint with other variants like 445W23S and 445C32E, differing primarily in electrical parameters such as load capacitance and temperature range.

Crystals Replacement Considerations

Direct substitutes include 445I23D12M00000 and 445A2XF12M00000. Verify that alternative parts match the 32 pF load capacitance and 12 MHz frequency. Check if the replacement's temperature range and ESR values are compatible with the existing circuit design.
