EZA-ST12AAAJ

Overview

The Panasonic EZA-ST12AAAJ is a surface-mount RC network from the EZA series, designed for EMI filtering applications. It integrates four resistors and four capacitors within a compact 1608 package measuring 4 x 2.1 x 0.65 mm. The component features a capacitance of 47 pF with a tolerance of -20% to +30%, and a resistance of 22 ohms with ±5% tolerance. Rated for 25 V DC, it operates between -25°C and +85°C.

Feature Summary

• Integrates four isolated resistor-capacitor pairs in a single surface-mount package
• Designed for effective electromagnetic interference (EMI) suppression
• Utilizes thin-film technology for stable electrical performance

Applications

• High-speed digital signal line filtering
• Clock circuit noise suppression
• Data bus protection against EMI

Procurement Notes

Verify the specific suffix 'ST12' to confirm the 22-ohm resistor and 47-pF capacitor configuration. Ensure the 1608 footprint matches the PCB layout. Confirm RoHS compliance status through official documentation before integration.

Selection Notes

Select this component when space-constrained designs require multiple RC filter stages. The 1608 package offers a balance between component count reduction and thermal management. Verify that the 25V rating and temperature range suit the target operating environment.
