STDCRG1-27M

Overview

The STDCRG1-27M is a surface-mount MHz crystal manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a nominal frequency of 27 MHz with a frequency tolerance of ±20ppm and stability of ±30ppm. The component features an 8pF load capacitance and 50 Ohms equivalent series resistance (ESR). It utilizes a 4-SMD, No Lead package with dimensions of 3.20mm x 2.50mm and a maximum height of 0.60mm. Designed for base harmonic operation, it supports a commercial temperature range of -10°C to +70°C.

Feature Summary

• Compact 4-SMD surface mount footprint suitable for space-constrained designs
• High frequency stability within the specified commercial operating temperature range
• Base harmonic oscillation mode for standard circuit integration

Applications

• General purpose clock signal generation in consumer electronics
• Timing reference for microcontrollers and digital logic circuits
• Communication module oscillator applications

Procurement Notes

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

Selection Notes

Select this component when a 27 MHz timing source is required in a compact 3.2x2.5mm SMD package. Ensure the design accommodates the 8pF load capacitance and 50 Ohms ESR characteristics. Verify that the -10°C to +70°C operating range meets the environmental requirements of the end product. Consider alternative packages if stricter thermal or size constraints exist.
