Procurement Notes
Verify the specific suffix codes against official TDK documentation to confirm exact electrical ratings and mechanical tolerances. Ensure that the M16 threaded interface matches the mounting hardware specifications of the target application panel. Confirm compliance requirements such as RoHS status through the manufacturer's current product declarations before finalizing procurement orders.
Selection Notes
Select this component when high-current handling and low impedance at high frequencies are required. The bolt-mount configuration offers superior thermal dissipation and mechanical stability compared to surface mount alternatives. Consider the 600 V DC rating for appropriate insulation coordination in DC bus applications.
Part Context
This component belongs to the B85321 series of feed-through capacitors manufactured by TDK Electronics. These components are engineered for use in environments where strict electromagnetic compatibility standards must be met. The series is widely utilized in industrial and automotive sectors for protecting sensitive electronics from conducted disturbances.
Replacement Considerations
Consult official TDK cross-reference lists for verified substitutes. Ensure any replacement maintains the M16 thread size and equivalent capacitance values to preserve circuit performance and mechanical fit.
