STDCSW2-30M

Overview

The STDCSW2-30M is a surface-mount crystal resonator manufactured by NDK. It operates at a fundamental frequency of 30 MHz with a frequency stability and tolerance of ±10 ppm. The component features a load capacitance of 10 pF and an equivalent series resistance (ESR) of 50 Ohms. 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 base harmonic operation and functions within a temperature range of -10°C to +75°C. It complies with RoHS standards and has a Moisture Sensitivity Level (MSL) rating of 1.

Feature Summary

• Compact 4-SMD no-lead surface mount design for automated assembly
• High frequency stability of ±10 ppm for precise timing applications
• Fundamental mode operation with low equivalent series resistance

Applications

• General purpose clock generation in consumer electronics
• Timing reference for microcontrollers and digital logic circuits
• Communication interface modules requiring stable frequency sources

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct load capacitance and tolerance specifications. Confirm that the 4-SMD no-lead package dimensions align with the target PCB footprint and soldering profile requirements. Check for any recent updates to the RoHS compliance status or REACH restrictions relevant to the procurement region.

Selection Notes

Select this component when a 30 MHz fundamental frequency with ±10 ppm stability is required in a small form factor. Ensure the circuit design accommodates the 10 pF load capacitance and 50 Ohm ESR characteristics. Verify that the operating temperature range of -10°C to +75°C meets the environmental conditions of the final application.
