LNCD1-20M

Overview

The LNCD1-20M is a 20 MHz fundamental mode quartz crystal resonator manufactured by NDK. It features an 8 pF load capacitance and operates within a temperature range of -10°C to +70°C. The component exhibits a frequency tolerance of ±50 ppm and a stability of ±30 ppm. It has an equivalent series resistance (ESR) of 70 Ohms maximum. The device is housed in a compact 2-SMD, No Lead package with dimensions of 5.0 mm x 3.2 mm and a maximum height of 1.5 mm. It complies with RoHS standards and has a Moisture Sensitivity Level (MSL) rating of 1.

Feature Summary

• Fundamental mode operation for stable frequency generation
• Compact surface-mount design suitable for automated assembly
• RoHS compliant construction for environmental safety

Applications

• General purpose clock signal generation in consumer electronics
• Timing reference for microcontroller systems
• Industrial control circuitry requiring standard frequency stability

Procurement Notes

Verify the specific lot date code and manufacturing origin upon receipt to ensure compliance with project requirements. Confirm that the received components match the LNCD1-20M part number exactly, as NDK offers various packages and tolerances. Check for physical damage to the SMD terminals before soldering. Ensure storage conditions adhere to the specified MSL 1 rating to prevent moisture absorption prior to reflow.

Selection Notes

Select this component when a 20 MHz timing source with moderate frequency stability is required. The ±50 ppm tolerance makes it suitable for applications where high precision is not critical. The 2-SMD package offers space efficiency compared to larger through-hole alternatives. Consider higher stability variants if the application environment experiences significant temperature fluctuations or requires tighter clock accuracy.
