LNR2E332MSE

The LNR2E332MSE is a screw-terminal aluminum electrolytic capacitor offering 3300 µF capacitance at a rated voltage of 250 V. Designed for general-purpose power applications, it combines high bulk capacitance with robust screw-terminal connections for secure mounting and high-current handling.

Key value propositions include high ripple-current capability (5.4 A at 120 Hz and 6.48 A at 100 kHz), a 5000-hour endurance rating at 85 °C, and a wide operating range from −25 °C to 85 °C, making it suitable for demanding industrial and power-electronics environments.

Key Features

• Capacitance & Voltage — 3300 µF nominal capacitance with a rated voltage of 250 V and tolerance of ±20% for bulk energy storage and smoothing at high DC voltages.
• Screw-Terminal Package — Radial can with screw terminals (φ51 body) for secure, low-resistance connections and robust mechanical mounting.
• High Ripple-Current Capability — 5.4 A at 120 Hz (low frequency) and 6.48 A at 100 kHz (high frequency) to support heavy AC ripple and switching loads.
• Endurance & Temperature Rating — Rated for 5000 hours at 85 °C with operating temperature range of −25 °C to 85 °C for sustained performance under elevated temperature stress.
• Leakage & Loss Characteristics — Specified leakage current of 2720 µA and capacitance stability/tan δ requirements per the LNR series datasheet for predictable behavior after long-term use.
• Mechanical Dimensions & Mounting — Body diameter φ51 mm with length 100 mm and standard 3-leg bracket provision for secure chassis attachment; nominal bolt size M5 for terminal connections.
• RoHS Compliant — Manufactured to meet RoHS environmental requirements.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and filtering at up to 250 V where 3.3 mF capacitance and high ripple-current capability are required.
• Power Conversion Systems — DC-link and energy-storage duties in converters and inverters that demand sustained ripple handling and thermal endurance at 85 °C.
• UPS and Backup Modules — Bulk energy storage for temporary hold-up and smoothing in uninterruptible power systems and standby power equipment.
• Laboratory and Test Equipment — Reliable high-voltage bulk capacitance for bench supplies and power-test setups that require screw-terminal connections for flexible wiring.

Unique Advantages

• Large Bulk Capacitance at High Voltage: 3300 µF at 250 V provides significant energy storage in a single capacitor, reducing the number of components required for bulk filtering.
• High Ripple-Current Handling: Rated ripple currents of 5.4 A (120 Hz) and 6.48 A (100 kHz) support both line-frequency and switching-regime loads without premature degradation.
• Screw-Terminal Robustness: Screw terminals and M5 nominal bolt sizing enable secure, low-resistance connections suitable for high-current power paths.
• Long Endurance at Elevated Temperature: 5000-hour endurance at 85 °C provides predictable lifespan and performance retention under continuous stress.
• Practical Mounting Options: φ51 body size with standard 3-leg bracket configuration simplifies chassis integration and mechanical stability.
• Regulatory Compliance: RoHS-compliant construction supports environmentally conscious designs.
