STDCZS1-26M

Overview

The STDCZS1-26M is a surface-mount quartz crystal resonator manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a fundamental frequency of 26 MHz with a load capacitance of 8 pF. The component exhibits a frequency tolerance of ±15 ppm and an equivalent series resistance (ESR) of 60 Ohms. It is housed in a compact 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a maximum height of 0.039 inches (1.00 mm). Designed for base mode operation, it supports a standard operating temperature range of -10°C to +75°C.

Feature Summary

• Compact 4-SMD no-lead surface mount package suitable for automated assembly
• Fundamental mode operation providing stable frequency generation
• Compliant with RoHS standards for environmental safety

Applications

• General purpose digital circuits requiring precise timing references
• Consumer electronics utilizing surface mount technology
• Industrial control systems operating within standard temperature ranges

Procurement Notes

Verify the specific suffix and frequency tolerance against the official NDK datasheet before procurement. Confirm that the required operating temperature range aligns with the -10°C to +75°C specification. Ensure compatibility with the 8 pF load capacitance in the target circuit design. Check for any recent product change notifications or end-of-life announcements from the manufacturer. Validate packaging options such as tape and reel availability for production volume requirements.

Selection Notes

Select this component when a 26 MHz fundamental frequency is required in a small form factor. Consider the 60 Ohm ESR value for oscillator circuit stability calculations. Evaluate the ±15 ppm tolerance against system clock accuracy requirements. Compare the -10°C to +75°C temperature range with application environmental conditions. Assess the 4-SMD package dimensions against available PCB real estate constraints.

Part Context

This part belongs to the NDK crystal resonator portfolio, designed for surface mount applications. It utilizes quartz crystal technology for frequency stability. The component is distinct from oscillators as it requires an external oscillator circuit. It serves as a passive frequency-determining element in electronic assemblies.
