LNCD1-12M

Overview

The LNCD1-12M is a surface-mount MHz crystal manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a nominal frequency of 12.0000 MHz with a frequency tolerance of ±50ppm and stability of ±50ppm. The component features an 8pF load capacitance and an equivalent series resistance (ESR) of 120 Ohms. Designed for base fundamental mode operation, it utilizes a 2-SMD, No Lead package measuring 5.00mm x 3.20mm with a maximum height of 1.50mm. The device supports a standard operating temperature range of -40°C to +85°C.

Feature Summary

• Compact 2-SMD no-lead surface mount package design
• Base fundamental oscillation mode operation
• Standard industrial temperature rating capability

Applications

• General clock signal generation in embedded systems
• Microcontroller oscillator circuits
• Consumer electronic timing references

Procurement Notes

Verify the specific lot date code and RoHS compliance status against current manufacturer declarations prior to procurement. Confirm that the 2-SMD footprint matches the target PCB layout dimensions exactly. Ensure ESR requirements align with the host oscillator circuit design specifications to guarantee reliable startup conditions.

Selection Notes

Select this component when a compact 2-pin SMD crystal is required for 12 MHz applications. The 120 Ohm ESR value dictates compatibility with specific oscillator topologies. Consider the ±50ppm stability limit against system timing accuracy requirements. Verify thermal performance within the specified -40°C to +85°C operational envelope for the intended environment.

Part Context

This part belongs to the NDK crystal portfolio, categorized under MHz crystals and resonators. It serves as a passive frequency control element within larger electronic assemblies. The 2-SMD form factor distinguishes it from larger through-hole or multi-pin SMD alternatives, offering space-saving integration for dense circuit board designs.
