Overview
The Panasonic EZA-ST62AAAJ is a discontinued RC (Pi) EMI filter circuit designed for surface mount applications. It features a fourth-order low-pass configuration with four channels, integrating resistors of 1 kOhms and capacitors of 47 pF per channel. The component operates within a voltage rating of 25 V DC and functions across a temperature range of -25°C to +85°C. Housed in a compact 1608 (4021 metric) concave package measuring 4.00 mm x 2.10 mm x 0.85 mm, it utilizes SMD/SMT termination types.
Feature Summary
- Integrates multiple passive components into a single compact surface-mount unit to reduce printed wiring board space compared to discrete parts.
Applications
- Data line protection in mobile devices
Procurement Notes
This component is officially discontinued by Panasonic Industry due to continuous decline in market demand. Verification of availability should focus on remaining stock from authorized distributors or secondary markets, as new production has ceased. Confirm end-of-life status and substitute part numbers before finalizing design implementations.
Selection Notes
Select this component only if legacy compatibility is required, as it is no longer in active production. Ensure the 1608 package dimensions and 25 V rating align with the target circuit constraints. Verify that the 1 kOhm resistance and 47 pF capacitance values meet the specific filtering requirements for the intended data lines.
Part Context
The EZA-ST62AAAJ belongs to the Panasonic EZA series of chip RC networks. This series is engineered to provide efficient EMI suppression while minimizing footprint on electronic assemblies. The ST variant specifically denotes the RC (Pi) topology, offering structured filtering for high-speed signal integrity in consumer electronics.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult Panasonic Industry for current alternative recommendations compatible with the EZA-ST series specifications.
