403C11E16M00000

Crystals Overview

The CTS-Frequency Controls 403C11E16M00000 is a surface-mount quartz crystal resonator operating at a nominal frequency of 16 MHz. It features a load capacitance of 20pF and offers high frequency stability of ±10ppm across the operating temperature range, with an initial frequency tolerance of ±10ppm. The component utilizes a 4-SMD, No Lead package with dimensions of 3.20mm x 2.50mm and a maximum height of 0.030 inches (0.75mm). It operates in fundamental mode with an equivalent series resistance (ESR) of 80 Ohms. The device supports a supply voltage context typical for standard crystals and functions within a temperature range of -20°C to +70°C.

Crystals Feature Summary

• High precision frequency stability of ±10ppm ensures reliable timing performance in sensitive digital circuits.
• Compact 4-SMD no-lead package design facilitates automated surface-mount assembly and space-constrained layouts.
• Fundamental mode operation provides stable oscillation characteristics with low equivalent series resistance.

Crystals Applications

• Microcontroller clock sources requiring precise timing synchronization
• Communication interfaces such as UART, SPI, or I2C bus controllers
• Digital signal processing systems needing stable reference frequencies

Crystals Procurement Notes

Verify that the target circuit design accommodates the specific 20pF load capacitance requirement to ensure accurate frequency output. Confirm that the PCB footprint matches the 3.2mm x 2.5mm 4-SMD no-lead package dimensions. Ensure the operating environment remains within the specified -20°C to +70°C range to maintain the guaranteed ±10ppm stability specification during production and deployment.

Crystals Selection Notes

Select this component when a 16 MHz fundamental frequency with tight ±10ppm stability is required for surface-mount applications. It is suitable for designs where space is limited due to its small 3.2x2.5mm footprint. Consider the 80 Ohm ESR value for oscillator circuit compatibility. This part is appropriate for general-purpose digital logic timing rather than high-stability RF applications requiring lower ppm values.

Crystals Part Context

This crystal belongs to the M403 Series from CTS-Frequency Controls, designed for general-purpose surface-mount applications. It serves as a passive frequency control element, distinct from active oscillators like the 625 series. The component relies on external oscillator circuits for operation and is RoHS compliant, meeting modern environmental standards for electronic manufacturing.

Crystals Replacement Considerations

The 403C11A13M00000 is listed as a similar alternative by the manufacturer, though it differs in frequency and package specifics. Direct substitutes must match the 16 MHz frequency, 20pF load capacitance, and 4-SMD no-lead package constraints to ensure functional compatibility without redesigning the host circuit board.
