Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required specifications. Check for obsolescence status as availability may be limited. Ensure compliance with RoHS directives if required by the application. Validate packaging details against project requirements before ordering.

Selection Notes

Select this component when a compact, third-order low-pass filter is needed for signal lines. The 1812 package size supports space-constrained designs. Ensure the 300 mA current rating meets the circuit demands. Verify that the 50 V voltage rating is sufficient for the operating environment. Consider the vertical mounting option for board density optimization.
