402F27112ILT

Crystals Overview

The CTS-Frequency Controls 402F27112ILT is a fundamental mode MHz crystal resonator designed for surface-mount applications. It operates at a nominal frequency of 27.12 MHz with a frequency tolerance and stability of ±10ppm. The component features a load capacitance of 12pF and an equivalent series resistance (ESR) of 100 Ohms. It utilizes a 4-SMD, No Lead package with dimensions of 2.00mm x 1.60mm and a maximum height of 0.55mm. The device supports operation within a temperature range of -40°C to +85°C and is RoHS compliant.

Crystals Procurement Notes

Verify the specific suffix requirements against the manufacturer's current documentation, as packaging and availability statuses may change. Confirm that the 100 Ohm ESR and 12pF load capacitance align with the target circuit design before procurement. Check for any recent lifecycle notices regarding discontinuation or last-time-buy status from official CTS channels.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental resonance is required with tight ±10ppm stability. Ensure the application circuit can accommodate the 100 Ohm ESR value. Compare against the 402F27133CLR if a ±30ppm tolerance is acceptable, or consider the 402F2701XILR variants for different frequency codes within the same 402 series footprint.

Crystals Part Context

This part belongs to the CTS 402 series of miniature crystals, which are characterized by their small 2.00mm x 1.60mm SMD footprint. The series is widely used in portable electronics and industrial controls where space constraints and thermal stability are critical factors for frequency reference accuracy.

Crystals Replacement Considerations

Direct substitutes include 402F27112IAR and 402F27112IJR from CTS-Frequency Controls. Parameter-equivalent alternatives may include parts with similar electrical characteristics but potentially different tolerances or packages, requiring careful verification of ESR and load capacitance.
