XDCAF21M400RAA00P0

Overview

The XDCAF21M400RAA00P0 is a monolithic crystal filter manufactured by Murata Electronics. It operates at a center frequency of 21.4 MHz and utilizes a surface-mount package with dimensions of 7.00mm x 5.00mm (6-SMD, No Lead). The component supports an operating temperature range from -20°C to +70°C. It features a two-pin configuration designed for board mounting applications requiring precise frequency selection.

Feature Summary

• Provides high-selectivity bandpass filtering utilizing quartz piezoelectric resonance
• Designed for compact surface-mount integration in radio frequency circuits
• Ensures stable signal processing within specified industrial temperature limits

Applications

• Radio frequency bandpass filtering
• Frequency selection in communication equipment
• Signal conditioning in wireless transceivers

Procurement Notes

Verify the specific electrical parameters against the official Murata datasheet before integration. Confirm that the 21.4 MHz center frequency aligns with system requirements. Ensure the 6-SMD package footprint matches the PCB layout. Validate the -20°C to +70°C operating range for the target environment. Check for any obsolete status or lifecycle changes directly from the manufacturer.

Selection Notes

Select this component when a fixed 21.4 MHz monolithic crystal filter is required for surface-mount designs. Consider the 7.0x5.0mm package size for space-constrained layouts. Evaluate the thermal performance against the -20°C to +70°C operational limits. Compare impedance characteristics with circuit design specifications. Ensure compatibility with automated assembly processes for SMD components.

Part Context

This part belongs to Murata's monolithic crystal filter series, which leverages quartz material properties for high-performance filtering. These filters are distinct from standard quartz resonators, offering superior selectivity for frequency generation and signal processing. The XDCAF series is engineered for reliability in demanding electronic environments.
