LNT2A333MSEB

The LNT2A333MSEB is a screw-terminal aluminum electrolytic capacitor specified for general-purpose power applications. It delivers high bulk capacitance (33,000 µF) at a 100 V rating in a robust radial can with screw terminals for secure electrical and mechanical connections.

Designed for heavy-duty smoothing and energy-storage duties, the part combines high ripple-current capability, a wide operating temperature range (−40°C to +105°C) and a 2,000-hour rated life at 105°C to meet demanding industrial power requirements.

Key Features

• Capacitance & Tolerance — 33 mF (33,000 µF) with ±20% tolerance for bulk energy storage and smoothing.
• Rated Voltage — 100 V DC continuous rating suited for medium-voltage DC bus applications.
• High Ripple Current — 12.7 A at 120 Hz (low frequency) and 14.61 A at 100 kHz (high frequency), enabling effective ripple absorption under both mains-frequency and switching conditions.
• Loss Angle (tan δ) — tan δ ≤ 0.3 (measurement reference: 120 Hz, 20°C), indicating controlled ESR-related losses for power applications.
• Leakage Current — Up to 5,000 µA (per datasheet leakage-current measurement condition: after 5 minutes’ application of rated voltage at 20°C).
• Temperature & Life — Operating range −40°C to +105°C with a rated life of 2,000 hours at 105°C under specified ripple and bias conditions.
• Package & Mounting — Radial can with screw terminals (φ76.2 × 140 mm), designed for secure screw-terminal mounting and robust mechanical attachment.
• Regulatory — RoHS compliant; supplied in cardboard packing for production handling.

Typical Applications

• Power supply bulk smoothing — Large capacitance and high ripple-current capability make the LNT2A333MSEB suitable for smoothing DC bus and bulk storage in industrial and commercial power supplies.
• DC link and energy storage — The 100 V rating combined with 33,000 µF capacitance supports DC-link filtering and short-term energy buffering in medium-voltage converter stages.
• UPS and backup systems — High ripple handling and extended operating temperature range support reliable performance in uninterruptible power and standby systems.
• Industrial drives and converters — Screw-terminal mounting and high ripple capability address mechanical and thermal demands typical in motor-drive and converter assemblies.

Unique Advantages

• High energy density: 33,000 µF at 100 V provides substantial bulk capacitance in a single radial can, reducing component count for energy-storage needs.
• Robust ripple performance: Rated ripple currents at both 120 Hz and 100 kHz let designers rely on the capacitor for smoothing across mains and switched-power regimes.
• Wide temperature tolerance: −40°C to +105°C operation and a defined 2,000-hour life at 105°C help ensure predictable behavior in harsh thermal environments.
• Screw-terminal mounting: Secure electrical and mechanical connection suitable for high-current installations and serviceable assemblies.
• Measurable loss characteristics: Specified tan δ (≤ 0.3 at 120 Hz, 20°C) provides a clear basis for thermal and ESR budgeting in power designs.
• Production-ready packaging: Cardboard packing and mass-production availability support procurement and assembly workflows.
