Overview
The Panasonic EZA-DT41AAAJ is a discontinued surface-mount RC network filter designed for EMI/RFI suppression. It features a low-pass, first-order Pi topology with four independent channels. Each channel integrates a 220-ohm resistor and a 22-picofarad capacitor. The component operates at a maximum voltage of 12 volts and is housed in a compact 1206 package measuring 3.20mm by 1.60mm.
Feature Summary
- Four-channel configuration providing independent signal filtering paths within a single package
- First-order low-pass RC Pi topology optimized for high-frequency noise attenuation
- Surface-mount construction suitable for automated assembly processes
Applications
- Digital equipment such as PCs, printers, and HDDs
- PCMCIA cards and PDAs
- Communication equipment
Procurement Notes
This part number is officially marked as obsolete by the manufacturer due to continuous decline in market demand. Verify availability through secondary distributors only. Confirm component authenticity and storage conditions carefully, as stock may be aged. No new production units are available directly from Panasonic Electronic Components.
Selection Notes
Select this component only if legacy compatibility is required for existing designs utilizing the EZA series. Evaluate alternative modern RC networks with similar electrical characteristics if redesigning. Ensure the 12V rating and 1206 footprint meet the target PCB constraints. Check for updated equivalents that offer improved supply chain stability.
Part Context
The EZA-DT41AAAJ belongs to the Panasonic EZA series of chip RC filters. This series includes variants like EZA-C, EZA-D, and EZA-N. The DT suffix indicates specific resistance and capacitance values within the family. Other models in the series share similar packaging and application scopes but differ in internal component values.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the available documentation. Designers should consult official Panasonic replacement guides or identify generic RC networks matching the 220 Ohm / 22 pF specifications.
