• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Power Systems — Provides bulk energy storage and smoothing where a 450 V, 82 µF electrolytic capacitor is required.
• High‑Temperature Equipment — Suited to designs requiring sustained performance at elevated ambient temperatures up to 105°C, backed by a 20,000‑hour endurance rating.
• Chassis/PCB Snap‑In Assemblies — Snap‑in radial can mounting simplifies secure installation in power assemblies and enclosures.

Unique Advantages

• Proven long life: 20,000 hours endurance at 105°C under rated conditions reduces replacement frequency and extends equipment service life.
• High DC voltage capability: 450 V rating supports high‑voltage power rails and applications that require elevated DC blocking voltage.
• Compact footprint: φ30 × 25 mm package delivers substantial capacitance density in a snap‑in radial can.
• Robust ripple performance: Rated 560 mArms at 120 Hz (82 µF) with documented frequency coefficients for higher frequency ripple handling.
• Validated electrical characteristics: Specified tan δ ≤ 0.20 and defined leakage current behavior (I ≤ 3√CV μA formula in datasheet), enabling predictable design margins.
• Regulatory compliance: RoHS‑compliant construction supports regulatory needs for many markets.
