EZA-ST43AAAJ

Overview

The Panasonic EZA-ST43AAAJ is a surface-mount RC network designed for EMI suppression. It integrates four resistors and four capacitors within a single SMD1608 package measuring 4 x 2.1 x 0.65 mm. The component features a rated voltage of 25 V DC, with each resistor valued at 220 Ohms having a ±5% tolerance and each capacitor at 100 pF with a -20/+30% tolerance. It operates reliably between -25°C and +85°C.

Feature Summary

• Integrates four isolated RC filter channels in a compact footprint
• Designed to attenuate electromagnetic interference on data lines
• Utilizes thin-film technology for stable signal processing

Applications

• Attenuating noise on high-speed digital data lines
• EMI filtering in portable electronic devices
• Signal integrity protection in consumer electronics

Procurement Notes

Verify the specific datasheet revision before integration, as component specifications may evolve. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the SMD1608 package dimensions align with your PCB land pattern design to prevent assembly defects.

Selection Notes

Select this component when space constraints require multiple discrete filters in a single package. The 220 Ohm resistance value is suitable for general-purpose data line damping. Verify that the 25 V rating meets the circuit's operational voltage requirements and that the temperature range covers the intended environment.

Part Context

This part belongs to the Panasonic EZA series of chip RC networks. These components are engineered for high-density mounting on printed circuit boards. The series provides consistent electrical performance for EMI/RFI suppression applications across various industrial and consumer electronics sectors.

Replacement Considerations

Check for direct substitutes within the EZA series with matching R/C values. Verify pin compatibility and thermal characteristics if replacing with components from other manufacturers.
