Procurement Notes

Verify the specific suffix against official manufacturer documentation, as ordering codes may indicate variations in packaging or tape-and-reel specifications that do not alter electrical performance. Confirm RoHS compliance status through the latest datasheet revision. Ensure the procurement source provides valid traceability records for automotive-grade components requiring AEC-Q200 certification. Cross-reference the part number with authorized distributor catalogs to confirm current manufacturing status and availability constraints.

Selection Notes

Select this component when designing circuits requiring robust common mode noise attenuation for differential signaling interfaces. The 1 kOhm impedance at 100 MHz makes it suitable for higher frequency signal integrity preservation. Consider the 230 mA current rating to ensure the component does not saturate under peak operating conditions. The wide temperature range supports deployment in harsh industrial or automotive settings where thermal stability is critical for consistent filter performance.

Part Context

This component belongs to the SRF3216A series of common mode chip inductors manufactured by Bourns Electronic Solutions. The series is engineered specifically for suppressing electromagnetic interference in compact electronic assemblies. These inductors are characterized by their small physical dimensions and high magnetic permeability cores, which allow for effective noise filtration without occupying excessive board real estate in modern miniaturized devices.

Replacement Considerations

The SRF3216-102Y is listed as an alternative variant within the same product family. Verify dimensional compatibility and electrical parameter alignment before substitution.
