416F27035IKR

Crystals Overview

The 416F27035IKR is a fundamental mode crystal oscillator manufactured by CTS-Frequency Controls. It operates at a nominal frequency of 27 MHz with a frequency tolerance of ±30 ppm and a load capacitance of 8 pF. The component utilizes a hermetic ceramic surface mount package in a 4-SMD, no-lead configuration, measuring 1.60 mm x 1.20 mm x 0.45 mm maximum height. It exhibits an equivalent series resistance (ESR) of 120 Ohms and maintains a frequency stability of ±50 ppm across an operating temperature range of -40°C to +85°C.

Crystals Procurement Notes

Verify the specific suffix 'KR' corresponds to tape and reel packaging when sourcing. Confirm that the 8 pF load capacitance matches the target circuit design requirements. Ensure compliance with RoHS3 standards if restricted substances are a concern. Check for moisture sensitivity level 1 classification during storage handling. Validate the 120 Ohm ESR against the oscillator circuit's drive level limitations.

Crystals Selection Notes

Select this component for applications requiring a 27 MHz reference signal in space-constrained designs. The 4-SMD package facilitates automated surface mount assembly processes. Consider the ±30 ppm initial tolerance for timing accuracy needs. The hermetic seal provides reliability advantages over non-hermetic alternatives in harsh environments. Evaluate the 1.60mm x 1.20mm dimensions against available PCB real estate.
