AWSCR-4.00CRLA-C15-T3

Overview

The AWSCR-4.00CRLA-C15-T3 is a surface-mount ceramic resonator manufactured by Abracon LLC, designed for precise frequency generation in electronic circuits. It operates at a nominal frequency of 4 MHz with a frequency tolerance of ±0.5% and stability of ±0.3%. The component features an integrated load capacitance of 15 pF and an impedance of 40 Ohms, eliminating the need for external capacitors. It supports a wide operating temperature range from -40°C to +85°C and is housed in a compact 3-SMD non-standard package measuring 4.50mm x 2.00mm x 1.00mm.

Feature Summary

• Integrates 15 pF load capacitance to simplify circuit design
• Provides stable 4 MHz frequency output with high accuracy
• Supports operation across extended industrial temperature ranges

Applications

• Microcontroller clock sources
• Communication system timing references
• General-purpose oscillator circuits

Procurement Notes

Verify that the replacement part matches the specific 4 MHz frequency, 15 pF capacitance, and 40 Ohm impedance parameters. Ensure the physical footprint corresponds to the 4.50mm x 2.00mm SMD package dimensions. Confirm compliance with RoHS3 standards if environmental regulations apply to the target assembly. Cross-reference the manufacturer's datasheet for any updates on pin configuration or mounting recommendations.

Selection Notes

Select this component when a cost-effective, space-saving solution is required for microcontroller applications. The built-in capacitor reduces bill-of-materials complexity compared to discrete crystal setups. Consider the ±0.3% stability requirement against application needs. Evaluate the 40 Ohm impedance compatibility with the driving circuitry to ensure signal integrity without additional buffering components.
