Overview of LNY2V123MSEH – Aluminum Electrolytic Capacitor, Screw Terminal, 12,000 µF / 350 V

The LNY2V123MSEH is a screw-terminal aluminum electrolytic capacitor providing 12,000 µF capacitance at a 350 V rating. Designed as a high-capacitance, screw-terminal radial can, it targets equipment downsizing where bulk energy storage and high-voltage capability are required in a compact footprint.

Its construction and specifications emphasize reliability under sustained ripple current and elevated temperature conditions: rated for operation from −40 °C to +85 °C, a 2000 hour load-life under rated ripple at 85 °C, and RoHS compliance for modern manufacturing requirements.

Key Features

  • High bulk capacitance: 12,000 µF (12 mF) at 350 V supplies substantial energy storage for high-voltage applications that need large capacitance in a single component.
  • Robust ripple-current handling: Rated ripple current of 24 A at 120 Hz and 33.6 A at 10 kHz supports demanding AC ripple conditions without premature degradation.
  • Endurance at elevated temperature: Load life specified as 2000 hours when rated ripple current is applied at 85 °C, demonstrating sustained performance under thermal stress.
  • Wide operating temperature: Specified for −40 °C to +85 °C to suit a wide range of environmental conditions.
  • Leakage and insulation characteristics: Leakage current after 5 minutes is limited to not more than 3√CV (µA) or 5 mA (whichever is smaller); insulation resistance exceeds 100 MΩ at DC 500 V between terminal and bracket.
  • Voltage proof and reliability tests: Withstands AC 2500 V for 1 minute between terminal and bracket; endurance and shelf-life conditioning follow defined test intervals from the datasheet.
  • Practical package and mounting: Radial can with screw terminals provides secure electrical and mechanical connections for assemblies, with dimensions L: 15 × D: 7.62 cm and a screw-terminal mounting style.
  • Regulatory compliance: RoHS compliant (2011/65/EU, (EU)2015/863), supporting environmental and manufacturing requirements.

Typical Applications

  • General purpose equipment: Use where a high-capacitance, high-voltage screw-terminal capacitor is required for bulk energy storage and system downsizing.
  • Screw-terminal assemblies: Suitable for equipment designs that prefer radial can capacitors with screw connections for robust terminal attachment.
  • High-capacitance, high-voltage modules: Ideal for installations specifying a 350 V, 12,000 µF capacitor with defined ripple-current and endurance characteristics.

Unique Advantages

  • Substantial single-component capacitance: Minimizes the number of parallel devices required by delivering 12,000 µF at 350 V in one package.
  • High ripple-current capability: Handles 24 A (120 Hz) and 33.6 A (10 kHz), reducing thermal stress and supporting stable operation under ripple loading.
  • Load-life proven at elevated temperature: 2000-hour endurance at 85 °C under rated ripple demonstrates predictable long-term behavior in thermally demanding applications.
  • Wide temperature tolerance: −40 °C to +85 °C rating and an impedance ratio of 12 between −40 °C and +20 °C help ensure performance across temperature extremes.
  • Engineered for secure mounting and serviceability: Screw-terminal radial can form factor simplifies mechanical installation and replacement in field-serviceable designs.
  • Measurable leakage and insulation standards: Clear leakage current limits and >100 MΩ insulation resistance at DC 500 V give quantifiable reliability metrics for design validation.

Why Choose LNY2V123MSEH?

LNY2V123MSEH combines high bulk capacitance and high-voltage capability in a screw-terminal radial can designed for equipment downsizing. Its rated ripple-current performance, defined endurance at 85 °C, and broad temperature range make it a reliable choice where predictable long-term behavior and robust mounting are required.

This part is suited to designers and buyers seeking a RoHS-compliant, general-purpose aluminum electrolytic capacitor that delivers measurable electrical and mechanical characteristics for mid- to high-voltage systems where a single high-capacitance component simplifies BOM and installation.
