LNY2W182MSEG

The LNY2W182MSEG is an aluminum electrolytic, screw‑terminal capacitor in Nichicon’s LNY series, delivering 1.8 mF nominal capacitance at a 450 V rating. Designed for general‑purpose applications and equipment downsizing, it combines high capacitance and high ripple‑current capability in a radial can with screw terminals.

This part is specified for operation from −40°C to +85°C, with a rated load life of 2000 hours at 85°C under applied ripple current, and is RoHS compliant.

Key Features

• Electrical Performance 1.8 mF nominal capacitance with ±20% tolerance and a 450 V rated voltage for high‑voltage energy storage and filtering.
• Ripple Current Handling High ripple capability with 8.9 A at 120 Hz and 12.46 A at 10 kHz to support applications with substantial AC ripple content.
• Thermal and Reliability Specified operating range −40°C to +85°C and a load life of 2000 hours at 85°C with rated ripple current; endurance requirements address capacitance change, tan δ and leakage current after test.
• Mechanical & Mounting Radial can with screw terminals (M5 bolt nominal for applicable diameters) for secure, high‑current connections and straightforward panel/bracket mounting.
• Insulation & Voltage Proof Insulation resistance more than 100 MΩ at DC 500 V between terminal and bracket, and no abnormality under AC 2500 V for 1 minute between terminal and bracket.
• Environmental Compliance Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Power Systems — Energy storage and smoothing where a high‑voltage electrolytic capacitor is required in a compact, screw‑terminal package.
• Equipment Downsizing — High capacitance in a radial can supports reduced system footprint while maintaining ripple handling and energy storage.
• High‑Ripple Circuits — Suitable where sustained ripple current at 120 Hz and higher frequencies (10 kHz) is present, based on the specified ripple current ratings.

Unique Advantages

• High‑Voltage Capability: 450 V rating enables use in high‑voltage DC link and filtering functions without series stacking.
• High Capacitance Density: 1.8 mF in a compact radial can (L: 7.5 × D: 6.35 cm) supports equipment downsizing objectives.
• Robust Ripple Performance: Specified ripple currents at both 120 Hz and 10 kHz provide predictable behavior across common power frequencies.
• Screw‑Terminal Mounting: M5 screw terminal configuration offers reliable, low‑impedance connection for high‑current applications and simple mechanical retention.
• Durability under Load: 2000‑hour rated life at 85°C with rated ripple current demonstrates endurance for long‑term operation under specified conditions.
• Verified Insulation and Voltage Proof: Insulation resistance and AC voltage proof test criteria support safe isolation between terminal and bracket.
