• Leakage and loss characteristics: Product-specified leakage current of 3650 µA and a tangent of loss angle (tan δ) of 0.2.
• Ripple current capability: 12.9 A at 120 Hz and 18.06 A at 10 kHz as specified for this part.
• Mechanical size and packaging: φ76.2 × 100L form factor (size dimension L: 10 cm × D: 7.62 cm) supplied in cardboard packing; mass production status.
• RoHS compliant: Conforms to RoHS requirements per the product data.
• Insulation and voltage proof (series specification): Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket and AC 2500 V one-minute voltage proof between terminal and bracket (per datasheet series characteristics).

Typical Applications

• General-purpose power circuits — For designs requiring 3.3 mF at 450 V in a screw-terminal package where long load life at elevated temperature is needed.
• General-purpose industrial systems — Suitable where robust mechanical mounting and high-voltage bulk capacitance are needed within the specified −25 °C to +85 °C range.
• General-purpose energy storage — Appropriate for applications that require significant stored charge at 450 V and specified ripple current handling.

Unique Advantages

• Large bulk capacitance at high voltage: 3300 µF at 450 V provides substantial energy storage for DC-link and high-voltage bulk requirements.
• Screw-terminal reliability: Screw terminals deliver secure, low-resistance connections suited to repeated installation and maintenance.
• Defined ripple performance: Rated ripple current values (12.9 A at 120 Hz, 18.06 A at 10 kHz) support designs with varying frequency ripple profiles.
• Proven endurance: 5000-hour load life at 85 °C under rated ripple current aligns with long-term performance expectations for continuous-duty applications.
• Clear electrical characteristics: Specified leakage current (3650 µA) and tan δ (0.2) enable predictable behavior in system-level designs.
• Regulatory conformity: RoHS compliance supports deployment in regions requiring restricted substance adherence.
