LNY2G332MSEGBN

The LNY2G332MSEGBN is a screw‑terminal aluminum electrolytic capacitor in Nichicon’s LNY series designed for higher capacitance at elevated voltage ratings. It provides 3.3 mF capacitance at a 400 V rating in a radial can with screw terminals, targeted at general‑purpose power applications and equipment downsizing.

Key value propositions include high ripple‑current capability across both low and high frequencies, a rated load life under ripple for 2000 hours at 85 °C, and RoHS compliance for environmental conformity.

Key Features

• High voltage and capacitance — Rated capacitance of 3.3 mF at 400 V for bulk energy storage and smoothing in high‑voltage power circuits.
• Screw‑terminal radial package — Radial can with screw terminals for secure, low‑impedance connections and robust mechanical mounting.
• Designed for equipment downsizing — Higher capacitance density intended to support smaller power module designs and compact equipment layouts.
• High ripple‑current capability — Rated ripple current of 13 A at 120 Hz and 18.2 A at 10 kHz to support demanding AC ripple conditions.
• Endurance at elevated temperature — Load life specified as 2000 hours with rated ripple current at 85 °C.
• Wide operating temperature range — Specified for operation from –40 °C to +85 °C.
• Leakage and insulation controls — Leakage current limited to 3√(C·V) µA or 5 mA (whichever is smaller) after 5 minutes; insulation resistance exceeds 100 MΩ at DC 500 V between terminal and bracket.
• Voltage proof between terminal and bracket — Withstands AC 2500 V for 1 minute without abnormality when tested between terminal and bracket.
• Capacitance tolerance — ±20% (measured at 120 Hz, 20 °C) for predictable capacitance budgeting in designs.
• RoHS compliant — Conforms to RoHS requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power circuits — Bulk smoothing and energy storage where a 3.3 mF, 400 V capacitor with high ripple capability is required.
• Compact power supplies and equipment downsizing — Higher capacitance per package supports reduced board space and smaller power module footprints.
• High-ripple environments — Suitable where sustained ripple currents (13 A at 120 Hz / 18.2 A at 10 kHz) are present and thermal endurance at 85 °C is required.

Unique Advantages

• High voltage plus high capacitance: Enables consolidation of bulk capacitance in 400 V systems, reducing the number of required units.
• Screw‑terminal robustness: Provides secure electrical and mechanical connections ideal for serviceable or rugged installations.
• Engineered for sustained ripple: Specified ripple currents at both 120 Hz and 10 kHz accommodate a range of switching and line frequency conditions.
• Reliable performance at elevated temperature: 2000‑hour load life at 85 °C offers predictable aging and endurance for thermal environments within the specified range.
• Measured leakage and insulation specifications: Defined leakage current limits and >100 MΩ insulation resistance support predictable system behavior and safety margins.
• Regulatory compliance: RoHS conformity supports environmentally restricted designs and procurement requirements.
