STDCIX1-40M

Overview

The STDCIX1-40M is a surface-mount crystal resonator manufactured by NDK. It operates at a fundamental frequency of 40 MHz with a frequency stability and tolerance of ±10 ppm. The component features an 8 pF load capacitance and a maximum equivalent series resistance (ESR) of 60 Ohms. It utilizes a 4-SMD, no-lead package with dimensions of 3.20mm x 2.50mm and a maximum height of 0.90mm. Designed for industrial applications, it supports a temperature range of -40°C to +85°C and complies with RoHS standards.

Feature Summary

• High frequency stability of ±10 ppm ensures precise timing performance
• Compact 4-SMD no-lead footprint suitable for space-constrained designs
• Industrial-grade temperature rating for reliable operation in varied environments

Applications

• Industrial control systems requiring stable clock signals
• Communication equipment utilizing 40 MHz reference frequencies
• Embedded systems needing compact surface-mount timing solutions

Procurement Notes

Verify the specific datasheet version, as documentation references may vary between STD-CIX-1 and other series identifiers. Confirm that the 60 Ohm ESR specification aligns with your oscillator circuit requirements. Ensure the 4-SMD package dimensions match your PCB land pattern design. Check for any specific handling instructions regarding moisture sensitivity level 1 compliance during assembly processes.

Selection Notes

Select this component when a 40 MHz fundamental mode crystal with tight ±10 ppm stability is required. The 8 pF load capacitance must match the host oscillator circuit's design parameters. Consider the 60 Ohm ESR limit to ensure proper oscillation startup. The industrial temperature range makes it suitable for harsher environments compared to commercial grade alternatives.
