AWSCR-4.00CRLB-C15-T3

Overview

The AWSCR-4.00CRLB-C15-T3 is a ceramic resonator from the Abracon AWSCR-CRLB series, designed for surface mount applications. It operates at a nominal frequency of 4 MHz with a frequency stability of ±0.4% and a tolerance of ±0.5%. The component features an integrated load capacitance of 15 pF and a motional impedance of 40 Ohms. It is housed in a compact 3-SMD non-standard package measuring 4.50mm x 2.00mm x 1.80mm. The device supports a wide operating temperature range from -40°C to +125°C and complies with RoHS3 standards.

Feature Summary

• Integrated 15 pF load capacitors eliminate external components
• Compact 3-SMD surface mount footprint for automated assembly
• Wide industrial temperature rating for harsh environments

Applications

• Microcontroller clock sources
• Communication module timing circuits
• Consumer electronics control boards

Procurement Notes

Verify that the specific suffix CRLB matches the required impedance and capacitance values for the target circuit design. Confirm that the 3-SMD non-standard package dimensions align with the PCB land pattern to ensure proper solder joint formation. Check for RoHS3 compliance requirements if the end product targets restricted substance regulations. Ensure the operating temperature range meets the environmental specifications of the final application.

Selection Notes

Select this component when a cost-effective timing solution with built-in capacitors is required for 4 MHz applications. The 40 Ohm impedance suits standard oscillator circuits without additional loading adjustments. Consider the physical size constraints as the 4.50mm length may require specific layout spacing compared to smaller alternatives. Validate that the ±0.4% stability meets the system's jitter and drift requirements.

Part Context

This part belongs to the AWSCR-CRLB series of ceramic resonators manufactured by Abracon LLC. These devices are engineered as direct replacements for quartz crystals in many applications, offering lower cost and higher shock resistance. The series provides various frequency options and package sizes to accommodate diverse embedded system designs.

Replacement Considerations

Direct substitutes include other 4 MHz ceramic resonators with 15 pF internal capacitance and similar SMD footprints. Verify impedance matching when swapping between different manufacturers' ceramic resonators to maintain oscillation reliability.
