• Extended industrial temperature capability
• Fundamental mode operation

Crystals Applications

• Industrial control systems
• Communication equipment
• Consumer electronics

Crystals Procurement Notes

Verify the specific suffix 'I' indicates the required -40°C to +85°C temperature rating, as standard variants may differ. Confirm the 16pF load capacitance matches the target oscillator circuit design. Ensure the 4-SMD footprint aligns with the PCB layout. Check RoHS compliance status if restricted substances are a constraint.

Crystals Selection Notes

Select this part when a 12 MHz reference is needed in harsh thermal environments. The 50 Ohm ESR suits standard drive level requirements. Compare against 445C23C12M00000 if a narrower -20°C to +70°C range suffices. Validate that the 16pF load capacitance does not require external trimming capacitors in the host circuit.

Crystals Part Context

This component belongs to the 445 Series of SMD crystals from CTS. It shares the 5x3.2mm form factor with other industry-standard packages. The 'I' suffix typically denotes the wider industrial temperature grade compared to commercial variants. It serves as a timing reference for microcontrollers and logic circuits.
