AWCR-4.00MD-AMMO

Overview

The AWCR-4.00MD-AMMO is a ceramic resonator manufactured by Abracon LLC, designed for surface-mount or through-hole integration depending on the specific variant configuration. This component operates at a fundamental frequency of 4.00 MHz and incorporates built-in capacitors with a specified capacitance value of 30 pF to simplify circuit design. It is housed in a Tape & Box (TB) package format, facilitating automated assembly processes. The device is RoHS3 compliant, ensuring adherence to environmental standards for restricted hazardous substances in electronic equipment manufacturing.

Feature Summary

• Integrates built-in capacitors to reduce external component count
• Operates at a stable 4.00 MHz fundamental frequency
• Complies with RoHS3 environmental regulations

Applications

• Microcontroller clock generation circuits
• Simple oscillator applications requiring moderate stability
• Consumer electronics timing references

Procurement Notes

Verify the exact physical package type and termination style against the specific datasheet revision, as the AMMO suffix indicates bulk tape packaging but does not define the mechanical footprint. Confirm that the 30 pF internal capacitance matches the load requirements of the target oscillator circuit to ensure proper frequency accuracy and startup reliability.

Selection Notes

Select this component when a cost-effective, low-stability clock source is required for non-critical timing applications. It is suitable for designs where board space is limited but high-frequency precision is not mandatory. Ensure the operating temperature range of the standard ceramic resonator aligns with the environmental conditions of the final product application.

Part Context

This part belongs to Abracon's ceramic resonator family, which provides an alternative to quartz crystals for applications tolerant of wider frequency tolerances. Ceramic resonators offer lower cost and smaller form factors compared to traditional crystal oscillators, making them ideal for budget-conscious consumer devices and simple digital logic timing needs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other Abracon AWCR series variants only if electrical parameters and mechanical dimensions are identical.
