EZA-DT43AAAJ

Overview

The EZA-DT43AAAJ is an EMI filter circuit manufactured by Panasonic Industry. It is a Chip RC Network configured as a PI filter with four channels. Each channel integrates a resistor of 220 Ohms and a capacitor of 100 pF. The component has a voltage rating of 25 V and operates within a temperature range of -25 C to +85 C. It utilizes SMD/SMT termination and is housed in a 1206 package measuring 3.2 mm in length, 1.6 mm in width, and 0.65 mm in height.

Feature Summary

• Integrates four independent RC filter channels within a single compact surface-mount package
• Provides electromagnetic interference suppression through low-pass filtering characteristics
• Designed for high-density mounting on printed circuit boards

Applications

• Data line protection in electronic equipment
• Signal integrity enhancement in communication interfaces
• Noise reduction in consumer electronics circuits
