Crystals Procurement Notes

Verify the specific suffix configuration against the manufacturer's datasheet to ensure compatibility with required load capacitance and tolerance specifications. Confirm that the tape and reel packaging aligns with your pick-and-place equipment capabilities. Check RoHS compliance status if restricted substances are mandated by your product regulations. Ensure storage conditions adhere to moisture sensitivity levels defined in the component documentation prior to soldering.

Crystals Selection Notes

Select this component when a standard 32.768 kHz reference is required for low-power timekeeping functions. The 12.5 pF load capacitance matches common oscillator circuit designs found in microcontrollers and dedicated RTC chips. The plastic package offers cost-effective protection compared to metal cans while maintaining adequate performance for general-purpose applications. Consider the physical dimensions for PCB layout constraints in compact enclosures.

Crystals Part Context

This part belongs to the CS1041 series of tuning fork crystals from Transko Electronics. These components are widely used as secondary oscillators in digital systems. The series provides various frequency options, though 32.768 kHz remains the industry standard for dividing down to one-second intervals. The CS1041 variant specifically denotes the plastic SMD form factor, distinguishing it from other package types within the broader product line.

Crystals Replacement Considerations

Cross-reference with other manufacturers offering 32.768 kHz SMD tuning fork crystals with 12.5 pF load capacitance. Verify mechanical footprint compatibility including the 10.4 x 4.0 x 3.6 mm dimensions. Ensure electrical parameters such as ESR and tolerance meet or exceed the original requirements. No direct substitute part numbers are confirmed in public documentation.
