AWSCR-14.75CV-T

Overview

The AWSCR-14.75CV-T is a built-in capacitance ceramic resonator manufactured by Abracon LLC, designed for surface-mount applications. It operates at a nominal frequency of 14.75 MHz with a tolerance of ±0.5% and a stability of ±0.3%. The component features an integrated load capacitance of 22 pF and an equivalent series resistance of 60 Ohms. It supports operating voltages of 6 V and 15 V and functions within a temperature range of -25°C to +85°C. The physical dimensions are 3.7 mm in length and 3.1 mm in width.

Feature Summary

• Built-in capacitance design eliminates external capacitors
• Surface-mount package for automated assembly
• Wide operating temperature range capability

Applications

• Microcontroller clock sources
• Communication module timing
• Embedded system oscillators

Procurement Notes

Verify the specific suffix 'T' indicates reel or cut tape packaging configuration as per manufacturer documentation. Confirm RoHS compliance status through official Abracon datasheets before integration. Ensure supply chain partners provide valid certificates of conformity. Cross-reference the full part number against current Abracon product lists to avoid obsolete variants. Validate that the 22 pF internal capacitance matches the circuit requirements without additional external components.

Selection Notes

Select this component when a compact solution for 14.75 MHz timing is required without external loading capacitors. Consider the 60 Ohm impedance for driver compatibility. Evaluate the -25°C to +85°C range against environmental conditions. Compare performance against quartz alternatives if higher stability is needed. Verify footprint compatibility with PCB layout constraints.

Part Context

This part belongs to the AWSCR-CV series of ceramic resonators from Abracon. The series offers various frequencies with built-in capacitance options. These components serve as cost-effective alternatives to crystal oscillators in consumer electronics. The CV designation typically indicates specific casing and mounting characteristics within the Abracon portfolio.

Replacement Considerations

Direct substitutes include other Abracon AWSCR models with matching 14.75 MHz frequency and 22 pF capacitance. Check pinout compatibility and mechanical dimensions for direct replacement. Verify electrical parameters such as ESR and stability match the original design requirements.
