STDCSF3-7.3728M

Overview

The STDCSF3-7.3728M is a surface-mount crystal manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a nominal frequency of 7.3728 MHz with a frequency tolerance and stability of ±20 ppm. The component features an 8 pF load capacitance and a maximum equivalent series resistance (ESR) of 250 Ohms. It utilizes a 2-SMD, no-lead package with dimensions of 8.0 mm in length, 4.5 mm in width, and a maximum height of 1.6 mm. Designed for fundamental mode operation, it supports a temperature range from -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Surface-mount design in a compact 2-SMD no-lead package
• Fundamental oscillation mode for stable frequency generation
• Compliant with RoHS3 environmental regulations

Applications

• Microcontroller clock sources
• Communication interface timing circuits
• General-purpose digital logic timing

Procurement Notes

Verify the specific package dimensions and ESR limits against the official NDK datasheet before integration. Confirm that the ±20 ppm stability meets the system timing requirements. Ensure the operating temperature range aligns with the intended application environment. Check for any specific handling precautions related to the surface-mount form factor during assembly.

Selection Notes

Select this component when a 7.3728 MHz fundamental frequency is required for standard baud rates or clock division. The 250 Ohm ESR limit suits applications with moderate drive levels. The 8 pF load capacitance must match the circuit's stray capacitance to ensure accurate frequency. Consider the 2-SMD footprint constraints for PCB layout density.
