Technology & family context
POSCAP uses a tantalum anode and polymer cathode. Do not confuse it with Panasonic’s aluminum polymer families. TPF and TPE documents are series references, not an assertion that every ordering code remains available.

Common procurement difficulties
Panasonic’s overview reports discontinuation of some TH, TPE, TPF and TC part numbers on 24 April 2026. Check the complete MPN against the notice and current manufacturer information. A listed example is not a current-production or stock claim.
What to verify
- Full MPN, technology and manufacturer series
- Capacitance, rated voltage, tolerance, ESR and leakage test conditions
- Ripple, derating, temperature, polarity and application requirements
- Case dimensions, land pattern, terminals and packaging suffix
- Batch/date-code requirements, source documents and required qualification
Lifecycle & obsolete requirements
Confirm lifecycle at complete-MPN level, including suffix and date of the manufacturer notice. Separate discontinued, not recommended for new designs and temporarily unavailable. Historic documentation is not proof of current production. An alternative requires engineering approval before changing the BOM.
