AWSCR-4.19CRLB-C15-T3

Overview

The AWSCR-4.19CRLB-C15-T3 is a ceramic resonator manufactured by Abracon LLC, designed for surface-mount applications. It operates at a nominal frequency of 4.19 MHz with a frequency tolerance of ±0.5% and a frequency stability of ±0.4%. The component features an integrated load capacitance of 15 pF and exhibits a maximum series resistance (ESR) of 40 Ohms. It is housed in a standard 3-SMD package with dimensions of 6.00 mm in length, 3.00 mm in width, and 1.50 mm in height. The device supports a wide operating temperature range from -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Integrated 15 pF load capacitance simplifies circuit design by eliminating external capacitors
• Compact 3-pin SMD footprint suitable for space-constrained PCB layouts
• Wide industrial temperature rating ensures reliable operation across extreme environments

Applications

• Microcontroller clock generation circuits
• Low-cost timing references for consumer electronics
• Industrial control system oscillators

Procurement Notes

Verify the specific suffix 'T3' against the manufacturer's latest datasheet to confirm packaging configuration and reel specifications. Ensure the selected variant matches the required 15 pF load capacitance and 40 Ohm impedance parameters for the target oscillator circuit design.

Selection Notes

Select this component when a cost-effective alternative to quartz crystals is required for moderate precision applications. The integrated capacitor reduces bill-of-materials complexity. Verify that the 4.19 MHz frequency aligns with the microcontroller or logic gate input requirements and that the 40 Ohm ESR is compatible with the driving circuit's gain capabilities.

Part Context

This part belongs to the AWSCR-CRLB series of ceramic resonators from Abracon. These components are positioned as economical timing solutions compared to traditional quartz crystals, offering higher volume production suitability for mass-market electronic devices where strict frequency stability is not critical.

Replacement Considerations

Direct substitutes include other 4.19 MHz ceramic resonators with 15 pF load capacitance and similar SMD footprints, such as the AWSCR-4.19CPLB-C15-T4 if higher stability is acceptable. Cross-reference pinout compatibility and thermal characteristics before substitution.
