CK4M000000S030

Overview

The CK4M000000S030 is a surface-mount ceramic resonator manufactured by TGS. It operates at a nominal frequency of 4.0MHz and features an integrated capacitor of 30pF. The component utilizes the 7434 SMD package type with dimensions of 7.4mm length, 3.4mm width, and 1.8mm height. It provides three connection pads for PCB mounting. The device offers a frequency accuracy of ±0.5% and includes built-in capacitors to simplify circuit design. It is rated for operation within a temperature range of -25°C to +85°C.

Feature Summary

• Integrated capacitor design eliminates external components
• Surface mount construction for automated assembly
• Three-pad configuration for stable mounting

Applications

• Microcontroller clock circuits
• Simple oscillator applications
• Consumer electronics timing references

Procurement Notes

Verify the specific manufacturer designation when sourcing, as TGS may refer to Tiger Electronic Co., Ltd in certain contexts. Confirm the package dimensions and pin count match the target footprint. Ensure the operating temperature range meets the environmental requirements of the final application. Cross-reference the part number with official distributor catalogs to confirm availability and authenticity.

Selection Notes

Select this component for cost-sensitive designs requiring moderate frequency stability. The built-in capacitor reduces bill of materials complexity compared to discrete crystal solutions. Consider the ±0.5% accuracy specification against system timing requirements. Evaluate the surface mount profile for compatibility with reflow soldering processes and existing manufacturing equipment.

Part Context

This ceramic resonator belongs to the family of passive timing components used in digital logic circuits. Unlike quartz crystals, it offers lower Q-factor performance but simplified integration. The 4.0MHz frequency is common for low-speed microcontrollers and simple communication interfaces. The component serves as a primary timebase generator where high precision is not critical.

Replacement Considerations

Compatible substitutes include other 4.0MHz ceramic resonators with similar package dimensions and built-in capacitance values. Verify that replacement parts maintain the same frequency tolerance and temperature range specifications.
