Procurement Notes

Verify the exact physical dimensions and terminal type against your PCB layout or chassis mounting requirements before ordering. Confirm the temperature rating matches your thermal management design. Ensure the supplier provides traceability documentation required for critical infrastructure projects. Check for any specific handling instructions regarding polarity and surge voltage limits during installation.

Selection Notes

Select this component when high bulk capacitance is required at moderate voltages in space-constrained industrial enclosures. Evaluate the allowable ripple current against your circuit's peak load demands. Consider the operating temperature range to ensure the projected lifespan meets system maintenance intervals. Compare equivalent series resistance (ESR) values if low impedance is critical for filtering performance.

Part Context

Cornell Dubilier capacitors are widely recognized in the power electronics industry for their robustness. This model belongs to a series focused on replacing older designs with higher performance metrics. The integration into Knowles Precision Devices highlights its role in specialized, mission-critical electronic systems where failure is not an option.

Replacement Considerations

Direct replacements must match the 100,000 µF capacitance and 162 V DC rating exactly. Verify that substitute components offer equal or superior ripple current ratings and ESR specifications. Physical footprint compatibility is essential for existing board layouts. Consult manufacturer cross-reference guides for approved equivalents from other reputable brands.
