CG18M43000S001

Overview

The CG18M43000S001 is a surface-mount ceramic resonator from the CRAV series, manufactured by TGS. It operates at a nominal frequency of 18.43 MHz with a tolerance of ±0.3%. The component features an impedance of 40 Ohms and functions within a temperature range of -25°C to +85°C. It utilizes a 3731 type package measuring 3.7mm in length, 3.1mm in width, and 1.2mm in height. The device has two pads for mounting and does not include built-in capacitance.

Feature Summary

• Surface-mount construction utilizing a compact 3731 type package for automated assembly integration
• High frequency stability achieved through a ±0.3% tolerance specification
• Designed without internal capacitance to allow flexible circuit configuration

Applications

• Microcontroller clock generation circuits

• Consumer electronics oscillator applications

Procurement Notes

Verify that the specific order matches the CRAV series designation and the 3731 package dimensions. Confirm the absence of built-in capacitance requirements against the target schematic design. Ensure the operating environment remains within the specified -25°C to +85°C range to maintain the stated ±0.3% frequency accuracy. Check for any recent updates to the datasheet regarding supply status or parameter changes.

Selection Notes

Select this component when a surface-mount solution is required for 18.43 MHz applications. Consider the 40 Ohm impedance and lack of internal capacitance when designing the load circuit. Evaluate the thermal constraints to ensure operation stays within the -25°C to +85°C limit. Compare physical footprint requirements against available board space for the 3.7x3.1x1.2mm package.
