MU00529-32.768K

Overview

The MU00529-32.768K is a surface-mount crystal resonator manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a fundamental frequency of 32.768 kHz with a load capacitance of 7 pF and an equivalent series resistance of 70 kOhms. The component utilizes a 2-SMD, no-lead package measuring 1.6 mm in length, 1.2 mm in width, and 0.4 mm in maximum height. Designed for base mode operation, it supports a standard operating temperature range of -40°C to +85°C.

Feature Summary

• Compact 1.6x1.2mm SMD footprint suitable for space-constrained designs
• Optimized for low power consumption applications
• High stability timing performance for precise clock generation

Applications
