LNY2W123MSEJBN

The LNY2W123MSEJBN is a screw-terminal aluminum electrolytic capacitor designed for high-capacitance, high-voltage power applications. As a radial can with screw terminals, it provides 12,000 µF at 450 V with construction tailored for general-purpose equipment where reliable bulk energy storage and filtering are required.

Key technical advantages include high allowable ripple current, a rated operating range of −40°C to +85°C, a 2,000-hour life at 85°C, and RoHS compliance—making it suitable for volume production and equipment downsizing where robust power-handling and easy installation are needed.

Key Features

• High Capacitance & Voltage — 12,000 µF at 450 V nominal capacitance and rated voltage for bulk energy storage and smoothing in high-voltage circuits.
• Screw Terminal Mounting — Radial can package with screw terminals for secure, low-resistance connections and straightforward mechanical installation.
• High Ripple Current Handling — 26,000 mA (26 A) at 120 Hz and 36,400 mA (36.4 A) at 10 kHz, supporting significant AC ripple and transient loads.
• Electrical Loss and Leakage — tan δ of 0.25 at 20°C and 120 Hz and leakage current specified at 5,000 µA, providing predictable loss characteristics for design calculations.
• Operating Temperature & Endurance — Rated for −40°C to +85°C with a load-life endurance of 2,000 hours at 85°C under rated ripple conditions.
• Mechanical Size & Packaging — Physical dimensions φ90 × 190 mm (L: 19 × D: 9 cm) with cardboard packing; mass production status indicates availability for volume builds.
• Regulatory Compliance — RoHS compliant to support environmental requirements in regulated markets.

Typical Applications

• Power Supply Filtering — Bulk smoothing and ripple attenuation in high-voltage DC power supplies where large capacitance and high ripple current capability are required.
• DC Link / Energy Storage — Energy buffering and decoupling in industrial power electronics and inverters that operate within the specified voltage and temperature range.
• Industrial and Commercial Equipment — General-purpose use in equipment that benefits from secure screw-terminal connections and long endurance at elevated operating temperatures.

Unique Advantages

• High Voltage with High Capacity — 450 V rating combined with 12,000 µF gives designers substantial stored energy per component for space-efficient power designs.
• Robust Ripple Performance — Separate ripple ratings at 120 Hz and 10 kHz (26 A and 36.4 A) allow predictable performance across low and high frequency ripple environments.
• Designed for Equipment Downsizing — Series characteristics and the LNY form factor support smaller overall power module footprints.
• Durability Under Load — 2,000-hour rated life at 85°C under applied ripple current provides a clear endurance benchmark for thermal and electrical stress planning.
• Installation Reliability — Screw terminals and radial can package simplify secure electrical and mechanical integration in production assemblies.
• Production-Ready Availability — Cardboard-packed, mass-production status supports procurement for volume manufacturing.
