Crystals Procurement Notes

Verify the specific suffix 'H' against the official manufacturer datasheet to confirm the exact electrical parameters and packaging configuration. Ensure the requested quantity aligns with the manufacturer's standard reel size of 1,000 units or available cut-tape options. Confirm lead times directly with authorized distributors as availability may vary.

Crystals Selection Notes

Select this component when a 12 MHz fundamental frequency with ±20 ppm tolerance is required in a 5.0x3.2mm footprint. The 32 pF load capacitance must match the oscillator circuit requirements. Consider the 50 Ohm ESR and limited temperature range (-20°C to +70°C) relative to the application environment.

Crystals Part Context

This component belongs to the 445 Series of glass-sealed crystals from CTS-Frequency Controls. These parts are designed for general-purpose timing applications requiring reliable performance in a small surface-mount form factor. The series offers various frequencies and load capacitances within standardized packages.
