Procurement Notes
This component is currently listed as no longer manufactured by the supplier. Procurement efforts should focus on verifying availability through authorized distributors or secondary market channels. Buyers must confirm the authenticity of the source and check for potential tariff implications if shipping to specific regions. Due to its discontinued status, lead times may vary significantly, and alternative sourcing strategies should be evaluated prior to finalizing orders.
Selection Notes
Engineers selecting this part should prioritize designs requiring passive RC filtering solutions within a small footprint. The 16-XFDFN package offers thermal dissipation benefits through the exposed pad. Considerations should include the specific impedance requirements matching the 200 Ohm resistance and 21 pF total capacitance values inherent to this model. Ensure the application environment supports the operating conditions defined for this specific filter variant.
Part Context
The PEMI8QFN/WR,132 belongs to the broader category of EMI/RFI filters produced by NXP Semiconductors. It shares functional similarities with other models in the PEMI series, such as the PEMI8QFN/RG,132 and PEMI4QFN/RE,132, which also utilize RC networks for interference suppression. These components are typically employed in scenarios where passive filtering is preferred over active solutions due to simplicity and reliability requirements.
Replacement Considerations
Direct substitutes include the PEMI8QFN/RG,132 and PEMI8QFN/WE,132 from Nexperia/NXP, which share similar RC Pi filter characteristics. Verification of pinout compatibility and exact electrical parameters is required before substitution. Given the discontinued status, cross-referencing datasheets for equivalent packages and performance metrics is essential.
