The 2 Ohm ESR is the key thermal parameter: at ripple frequencies typical of a buck converter, the ESR sets the self-heating and the capacitor's ripple-current limit. The 16 V rating provides a 50% derating margin on a 5 V rail, which is standard practice to reduce tantalum failure rates from voltage surges.
The TAJ series remains a standard molded tantalum line with broad distributor stocking.
Engineers need to verify electrical characteristics and pinout before design-in.
Buyers need to quickly find a supplier with stock to fill BOM lines.
Price comparison across distributors is critical for sourcing decisions.
Lifecycle status affects long-term availability and design risk.
Cross-referencing ensures supply chain flexibility when the exact part is unavailable.
Design engineers need PCB land pattern dimensions to ensure proper mounting.
