STDCSQ1-26M

Overview

The STDCSQ1-26M is a surface-mount crystal resonator manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a fundamental frequency of 26 MHz with a load capacitance of 10 pF. The component provides a frequency stability of ±10 ppm and a tolerance of ±20 ppm. It features an equivalent series resistance (ESR) of 50 Ohms and utilizes a 4-SMD, No Lead package measuring 3.20mm x 2.50mm. Designed for base mode operation, it supports a temperature range of -40°C to +85°C.

Feature Summary

• High frequency stability of ±10 ppm suitable for precision timing applications
• Compact 4-SMD No Lead package design for automated surface mount assembly
• Wide operating temperature range from -40°C to +85°C

Applications

• Mobile communication devices
• Automotive electronics systems
• IoT sensor modules

Procurement Notes

Verify the specific ordering suffix against the official NDK datasheet to ensure correct frequency tolerance and packaging configuration. Confirm that the selected variant matches the required load capacitance and ESR specifications for the target circuit design. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current availability status before finalizing procurement orders.

Selection Notes

Select this component when a 26 MHz reference signal with ±10 ppm stability is required in a compact SMD form factor. Ensure the application circuit accommodates the 10 pF load capacitance and 50 Ohm ESR characteristics. Verify that the -40°C to +85°C operating temperature range meets the environmental requirements of the end product.
