The NUF2230XV6T1 is a discontinued two-channel RC (Pi) EMI filter integrated with electrostatic discharge protection, manufactured by onsemi. It features a low-pass configuration with a resistance of 100 ohms and capacitance of 16 pF per channel. The device operates within a temperature range of -40°C to 85°C and utilizes an SOT-563 or SOT-666 surface-mount package measuring 1.60mm x 1.20mm x 0.60mm. Designed for mobile data lines, it provides attenuation of -30dB at frequencies between 800MHz and 900MHz, with a cutoff frequency of 125MHz.
This component is officially marked as obsolete and no longer manufactured by onsemi. Verification of current availability requires checking authorized distributors for remaining stock or approved replacement parts. Do not assume standard supply chain availability. Confirm RoHS compliance status separately, as historical documentation indicates potential non-compliance for this specific revision. Source only from verified channels to ensure authenticity.
Select the direct replacement NUF2230XV6T1G for equivalent functionality. Verify that the updated version meets specific environmental compliance requirements such as RoHS, which may differ from the original NUF2230XV6T1 specifications. Ensure the SOT-563/SOT-666 footprint remains compatible with existing PCB layouts when transitioning to the substitute part number.
The NUF2230 series belongs to onsemi's portfolio of passive components designed for signal conditioning and protection. This specific model combines filtering and protection functions into a single compact package, reducing board space compared to discrete solutions. It targets applications requiring simultaneous EMI reduction and transient voltage suppression for sensitive digital interfaces.
NUF2230XV6T1G is the confirmed direct replacement part number.
