Procurement Notes

Verify the specific suffix requirements against the official datasheet to ensure compliance with RoHS standards, as indicated by the LF designation. Confirm that the 4-40 thread size matches the mechanical design of the target enclosure. Ensure the 200V rating and 10A current capacity align with the circuit's operational limits before finalizing procurement orders.

Selection Notes

Select this component when high-frequency noise attenuation is required on lines carrying moderate currents. The axial bushing form factor is suitable for direct panel penetration. Compare the 1000 pF capacitance value against system impedance requirements to ensure effective filtering without excessive signal loading. Verify thermal stability needs against the specified operating temperature range.
