Notes / Handling

• Observe polarity; do not exceed rated voltage (VDC + VAC ripple must remain within rating).
• Re‑aging may be required after long shelf storage. Follow Itelcond recommended re‑aging procedure if stored >2 years.
• Consult the Itelcond datasheet for frequency/temperature ripple correction factors, expected‑life graphs, surge/ transient limits and mechanical mounting details.
