405C11A16M80000

Crystals Overview

The CTS-Frequency Controls 405C11A16M80000 is a surface-mount MHz crystal resonator operating at a fundamental frequency of 16.8 MHz. It features a frequency stability and tolerance of ±10ppm, with a load capacitance of 10pF and an equivalent series resistance (ESR) of 60 Ohms. Designed for the -20°C to +70°C industrial temperature range, this component utilizes a 4-SMD, no-lead package measuring 5.00mm x 3.20mm in footprint and 0.85mm in maximum height. The device supports base harmonic operation mode.

Crystals Feature Summary

• Provides precise frequency control through fundamental mode crystal resonance
• Supports automated assembly via compact surface-mount packaging
• Enables circuit shutdown or isolation through low power consumption characteristics

Crystals Applications

• Industrial communication systems requiring stable clock signals
• Microcontroller peripheral timing circuits
• Consumer electronics utilizing standard serial interfaces

Crystals Procurement Notes

Verify the specific package dimensions and thermal requirements against the target PCB layout before finalizing procurement decisions. Confirm that the operating environment remains within the specified -20°C to +70°C range to ensure long-term frequency stability. Ensure compatibility with the intended load capacitance values in the host circuit design to maintain accurate oscillation performance.

Crystals Selection Notes

Select this component when a 16.8 MHz fundamental frequency is required for synchronous data transmission or processing clocks. Consider the ±10ppm tolerance for applications demanding tight timing accuracy without active temperature compensation. Evaluate the 4-SMD form factor for space-constrained designs where leaded alternatives are unsuitable.

Crystals Part Context

This part belongs to the 405 Series of MHz crystals manufactured by CTS-Frequency Controls. The series focuses on general-purpose surface-mount solutions for consumer and industrial markets. These components serve as primary timekeeping elements in digital logic circuits, replacing older through-hole technologies with more compact and reliable SMD variants.

Crystals Replacement Considerations

Direct substitutes include the 405C11A19M80000 from the same manufacturer family, which shares identical physical dimensions and electrical interface standards while differing only in nominal frequency output specifications.
