AWSCR-4.00CP-T

Overview

The AWSCR-4.00CP-T is a surface-mount ceramic resonator manufactured by Abracon LLC, designed for precise frequency control in electronic circuits. Operating at a nominal frequency of 4.0000 MHz, this component features an integrated load capacitance of 30 pF to simplify circuit design and reduce external component requirements. It exhibits a frequency tolerance of ±0.5% and a stability of ±0.3%, ensuring reliable performance across varying conditions. The device operates within a temperature range of -40°C to +85°C and has a series resistance of 30 Ohms. Packaged in a standard SMD form factor, it supports automated assembly processes.

Feature Summary

• Integrates 30 pF load capacitance directly into the package to minimize external circuit complexity.
• Provides high frequency stability with ±0.3% tolerance for accurate timing applications.
• Supports wide operating temperatures ranging from -40°C to +85°C for industrial environments.

Applications

• Microcontroller clock sources
• Communication interface timing
• General-purpose digital logic circuits

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm that the 30 pF internal capacitance matches the oscillator circuit requirements of the target microcontroller or logic family. Ensure the 30 Ohm impedance is compatible with the driving gate's output characteristics to guarantee proper oscillation startup.

Selection Notes

Select this component when a 4 MHz reference is required with minimal external components. Compare against the AWSCR-4.00CPLB-C30-T4 if higher temperature stability up to 125°C is needed. Verify that the SMD footprint dimensions align with the PCB layout constraints. Consider the ±0.5% tolerance sufficient for most general digital applications requiring precise timing.

Part Context

This part belongs to Abracon's AWSCR series of ceramic resonators, which are widely used as cost-effective alternatives to quartz crystals. The CP series specifically denotes standard surface-mount packages with built-in capacitors. These components bridge the gap between simple RC oscillators and more complex crystal oscillators, offering better accuracy than RC solutions without the sensitivity of bare crystals.

Replacement Considerations

AWSCR-4.00CPLB-C30-T4 offers similar electrical specifications but supports an extended temperature range up to 125°C compared to the standard 85°C limit of the CP-T variant.
