EZA-CT20AAAJ

Overview

The Panasonic EZA-CT20AAAJ is a surface-mount RC network from the EZA series, housed in a 1608 (0805) package with dimensions of 4 x 2.1 x 0.65mm. It integrates four resistor-capacitor pairs, featuring a capacitance value of 47pF with a tolerance of -20% to +30%, and a resistance value of 47Ω with a ±5% tolerance. Designed for DC voltages up to 25V, this component utilizes thin-film technology for stable performance in compact electronic designs.

Feature Summary

• Integrates four independent RC circuits within a single compact surface-mount package
• Utilizes thin-film construction for consistent electrical characteristics
• Designed for high-density PCB layouts with a low-profile form factor

Applications

• Signal filtering in communication equipment
• Timing circuits in digital logic systems
• Coupling and decoupling networks in consumer electronics

Procurement Notes

Verify the specific suffix 'AAAJ' against the manufacturer's current datasheet to confirm exact tolerance and termination specifications. Ensure the ordering part number matches the required capacitance and resistance values, as variations exist within the EZA-CT family. Cross-reference package dimensions with your PCB footprint library to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component when space constraints require multiple discrete RC elements in a single footprint. The 1608 package offers a balance between component density and thermal dissipation. Consider the -20/+30% capacitance tolerance if precise timing is not critical, or verify if tighter tolerance variants are available for more sensitive applications.

Part Context

This component belongs to Panasonic's EZA series of passive integrated networks, which are designed to replace multiple discrete resistors and capacitors. The EZA-CT variant specifically denotes a chip-style RC network configuration, widely used in portable devices and automotive electronics where board real estate is limited and reliability is paramount.

Replacement Considerations

Check Panasonic's official substitution guide for equivalent EZA-CT models with different RC values. Verify that any alternative maintains the same 1608 package dimensions and voltage rating to ensure direct mechanical and electrical compatibility without redesigning the PCB layout.
