LNY2G332MSEF

The LNY2G332MSEF is a screw-terminal aluminum electrolytic capacitor in Nichicon's LNY series, delivering 3.3 mF (3300 µF) at a 400 V rating. Designed as a radial can with screw terminals, it targets general-purpose power applications where high capacitance, robust ripple handling and reliable end-of-life performance are required.

Key value drivers include high ripple current capability, a 2000-hour rated life at 85°C under ripple load, and a compact φ51 × 145L footprint suited for equipment downsizing.

Key Features

• Capacitance & Voltage: 3.3 mF (3300 µF) rated at 400 V for high-energy storage in a single device.
• Screw Terminal Package: Radial can with screw terminals (nominal bolt dia. M5 for φ51) for secure, low-impedance connections in power assemblies.
• High Ripple Current Capability: 12.4 A at 120 Hz (low frequency) and 17.36 A at 10 kHz (high frequency) to support designs with significant AC ripple currents.
• Endurance & Temperature Range: Rated for 2000 hours at 85°C under applied ripple; operating temperature range −40°C to +85°C.
• Loss Angle & Leakage: tan δ = 0.25 (reference measurement conditions available in series datasheet) and specified leakage current of 3440 µA.
• Tolerance & Polarization: ±20% capacitance tolerance (polarized device) for predictable performance in DC circuits.
• Form Factor & Packaging: φ51 × 145L size (L: 14.5 × D: 5.1 cm), supplied in cardboard packing and available in mass production.
• Regulatory: RoHS compliant as stated for the LNY series.

Typical Applications

• General-Purpose Power Systems: Provides bulk energy storage and smoothing where a high-voltage, high-capacitance polarized capacitor is required.
• Equipment Downsizing: Suited for designs aiming to reduce module size while maintaining capacitance, leveraging the high capacitance in a φ51 footprint.
• High Ripple Current Environments: Appropriate for circuits that impose substantial ripple currents, supported by specified low- and high-frequency ripple ratings.

Unique Advantages

• High Voltage and High Capacitance Combination: 400 V rating with 3300 µF capacitance enables significant energy density for DC power applications.
• Robust Ripple Handling: Specified ripple currents of 12.4 A (120 Hz) and 17.36 A (10 kHz) reduce the need for parallel devices in high-ripple designs.
• Long Endurance Under Load: 2000-hour load life at 85°C under rated ripple current provides predictable aging and maintenance planning.
• Secure Screw-Terminal Mounting: M5-compatible screw terminals and radial can construction ensure reliable mechanical and electrical connections in power assemblies.
• Clear Specification Set: Tangent of loss angle, leakage current, operating temperature, and tolerance are documented to support design verification and qualification.
• Production Availability and Packaging: Mass production status and cardboard packing support volume procurement and handling.
