F1 Technology and Simulated Breakdown Screening

F1 Technology and Simulated Breakdown Screening

KEMET Corporation has introduced new technologies targeted for high-reliability solutions in industries such as military, aerospace, and medical. These technologies allow KEMET to provide the highest-reliability capacitors with high breakdown voltage resistance as well as stable and low DC leakage current. Details of these technologies are outlined below:

F1 Technology for Improved Anode Quality

KEMET’s F1 Technology package incorporates three process methodologies for improved anode quality. Two of these technologies aid in slowing the crystallization process that naturally occurs in the anode. By minimizing oxygen and carbon content in our anodes, we address two of the main contaminants that can lead to crystallization of the anode. The remaining technology provides a stronger mechanical connection point between the Ta lead wire and Ta anode, thus improving robustness and product reliability.

KEMET is offering our F1 technology currently on limited part types as indicated below:

T493 Series - select D and X case capacitance values in 20 V and higher rated voltage
T497 Series - select H case capacitance values in 20 V and higher rated voltage

Simulated Breakdown Screening

KEMET has developed a special patented screening technique which allows the identification of capacitors with hidden defects in the dielectric, without any damage to the general population of the capacitors. The screening is based on the simulation of breakdown voltage (BDV) without actually damaging the capacitors. The BDV test is an ultimate test of the dielectric in a capacitor. Low BDV indicates defects in the dielectric and, therefore, higher probability of failure in the field. High BDV indicates stronger dielectric and high-reliability performance in the field. This new screening method allows KEMET to identify the breakdown voltage of each individual capacitor so that we provide only the strongest capacitors from each lot.

KEMET is offering our screening technology currently on part types in the T493 and T497 product series.

KEMET offers these technologies in the following arrangements: 1) F1 Technology alone, 2) Simulated Breakdown Screening alone, or 3) combination of both F1 and Simulated Breakdown Screening technologies. Please see Frequently Asked Questions or contact KEMET tantalum product management for details on the ordering of these product reliability improvements.
