STDCQR1-16M

Overview

The STDCQR1-16M is a surface-mount MHz crystal manufactured by NDK. It operates at a nominal frequency of 16 MHz with a frequency tolerance and stability of ±15ppm. The component features an 8pF load capacitance and an equivalent series resistance (ESR) of 80 Ohms. Designed for fundamental mode operation, it utilizes a 4-SMD, No Lead package with dimensions of 3.20mm x 2.50mm and a maximum height of 0.60mm. The device supports a standard operating temperature range from -10°C to +75°C.

Feature Summary

• Fundamental resonance mode operation for stable frequency generation
• Compact 4-SMD no-lead surface mount package design
• RoHS compliant construction meeting environmental standards

Applications

• General clock signal generation in electronic circuits
• Microcontroller and processor timing references
• Communication interface synchronization modules

Procurement Notes

Verify the specific manufacturer part number STDCQR1-16M against official NDK documentation to ensure authenticity. Confirm that the received components match the specified 16MHz frequency, 8pF load capacitance, and 4-SMD package dimensions. Check for RoHS compliance markings and ensure storage conditions adhere to the specified moisture sensitivity level requirements prior to assembly.

Selection Notes

Select this component when a 16MHz fundamental mode crystal is required with ±15ppm stability. Ensure the application circuit provides an 8pF load capacitance to maintain frequency accuracy. Verify that the operating environment remains within the -10°C to +75°C range. Consider the 80 Ohm ESR value for oscillator circuit compatibility and confirm the 4-SMD footprint fits the PCB layout constraints.
