LNT2E332MSE

The LNT2E332MSE from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNT series, offering 3.3 mF (3300 µF) capacitance at a 250 V rating. It is a radial can with screw terminals engineered for general-purpose power applications that require high capacitance, elevated temperature endurance, and robust ripple handling.

Designed for operation from −25°C to +105°C and specified with a 2000 hour endurance at 105°C, this capacitor provides a balance of capacitance density, ripple capability and service-life suitable for demanding industrial and power electronics environments.

Key Features

• Capacitance & Voltage — 3.3 mF (3300 µF) nominal capacitance with a rated voltage of 250 V and tolerance of −20% to +20%, suitable for bulk energy storage and smoothing in high-voltage DC circuits.
• Screw-Terminal Package — Radial can with screw terminals (φ63.5 × 100 mm) for secure, high-current connections and straightforward mounting in chassis or busbar-based layouts.
• High Ripple Current Capability — Rated low-frequency ripple current 4.3 A (120 Hz) and high-frequency ripple current 5.16 A (100 kHz), supporting continuous AC ripple and switching workloads.
• Elevated-Temperature Endurance — Rated life of 2000 hours at +105°C under specified conditions, enabling sustained operation in high-temperature environments.
• Leakage and Dissipation — Specified leakage current of 2720 µA and tangent of loss angle (tan δ) of 0.2 measured at 20°C, 120 Hz, for predictable loss characteristics in power designs.
• Regulatory & Packaging — RoHS compliant; supplied in cardboard packaging for handling and storage.

Typical Applications

• General-purpose power filtering — Bulk smoothing and decoupling in power supply rails where 3300 µF at 250 V and high ripple handling are required.
• DC link / energy storage — Energy buffering in mid-to-high-voltage DC circuits that demand robust screw-terminal connections and elevated temperature capability.
• Industrial power electronics — Filtering and ripple absorption in converters and motor drive power stages operating up to 105°C.

Unique Advantages

• High-capacity, high-voltage option: 3.3 mF at 250 V provides substantial energy storage within a compact radial can form factor.
• Robust termination for high-current layouts: Screw terminals enable secure mechanical and electrical connection for busbar or heavy-gauge wiring.
• Designed for elevated temperatures: 2000 hour life at 105°C offers predictable endurance in hot operating environments.
• Wide ripple-frequency performance: Specified ripple current at both low (120 Hz) and high (100 kHz) frequencies supports a range of power topologies.
• Measurable, predictable losses: Specified tan δ and leakage current values allow engineers to model dissipation and standby loss precisely.
• RoHS compliant packaging: Meets regulatory requirements and is delivered in cardboard packing for handling and storage.
