Overview
The Panasonic ELK-D501FB is an obsolete surface-mount EMI/RFI filter designed for data lines in mobile devices. It utilizes LC technology to provide low-pass filtering capabilities. The component features a compact 0805 (2012 Metric) package with dimensions of 2.00mm x 1.25mm and a height of 1.09mm. It operates without ESD protection and has a tolerance of 30%. The device is rated for a current of 100mA and includes a moisture sensitivity level of 1, indicating unlimited shelf life under standard conditions.
Feature Summary
- Provides low-pass filtering for electromagnetic interference suppression using LC network topology
- Designed specifically for signal integrity preservation on data lines within mobile device architectures
- Utilizes a compact surface-mount footprint suitable for high-density PCB layouts
Applications
- Data line filtering for mobile devices
- EMI suppression in portable electronics
- Signal conditioning for communication interfaces
Procurement Notes
This component is officially listed as obsolete by the manufacturer. Verification of availability should focus on surplus distributors or secondary markets rather than direct factory orders. Confirm the specific revision status and authenticity when sourcing from non-authorized channels, as lead times and stock levels vary significantly across third-party suppliers.
Selection Notes
Engineers replacing this part must account for its obsolete status and seek equivalents that match the 0805 footprint and LC filtering characteristics. Ensure the substitute component supports the required current rating and maintains similar insertion loss profiles for the target frequency range. Verify compatibility with existing assembly processes and reflow soldering temperatures.
Part Context
The ELK series represents Panasonic's lineup of passive EMI filters intended for consumer electronics. This specific model addresses noise reduction requirements in compact mobile form factors. As an LC filter, it combines inductive and capacitive elements to attenuate high-frequency noise while preserving signal integrity on data transmission lines.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Due to the obsolete status, engineers should evaluate generic 0805 LC filters with comparable electrical specifications from other manufacturers.
