Overview of LNY2G122MSEF – Aluminum Electrolytic Capacitor, Screw Terminal, 400 V, 1.2 mF

The LNY2G122MSEF is a screw-terminal aluminum electrolytic capacitor rated at 400 V and 1.2 mF (1200 µF) designed for general-purpose power applications. Its screw-terminal can and robust can-style package support high ripple currents and secure mechanical connections for high-current power hardware.

Built for reliability in compact equipment, this part offers a 2000-hour load life at 85°C, RoHS compliance, and packaging suitable for mass production, making it a practical choice where steady bulk capacitance, high voltage rating and durable terminations are required.

Key Features

  • Capacitance & Voltage — 1.2 mF nominal capacitance with a 400 V rated voltage and ±20% tolerance (120 Hz, 20°C), providing substantial energy storage for high-voltage systems.
  • High Ripple Current Capability — Supports 7.10 A at 120 Hz (low frequency) and 9.94 A at 10 kHz (high frequency), allowing effective smoothing under heavy AC ripple conditions.
  • Endurance & Temperature Range — Rated for 2000 hours of operation at 85°C with an operating temperature range of −40°C to +85°C, enabling stable performance in elevated-temperature environments.
  • Leakage and Loss Characteristics — Specified leakage current of 2070 µA and a tangent of loss angle (tan δ) of 0.25 at 20°C and 120 Hz, for predictable dissipation and self-heating behavior.
  • Rugged Mechanical Package — φ51 × 65 mm can with screw terminal mounting (radial can, screw terminals) and M5 bolt nominal terminal arrangement for secure, low-resistance connections.
  • Safety & Electrical Integrity — Datasheet specifies insulation resistance >100 MΩ at DC 500 V between terminal and bracket and voltage proof of AC 2500 V for 1 minute, ensuring electrical isolation and withstand capability.
  • Compliance & Production — RoHS compliant and supplied in cardboard packing; the part is in mass production.

Typical Applications

  • General-purpose power systems — Bulk energy storage and smoothing in 400 V-class power equipment requiring 1.2 mF capacitance and screw-terminal connections.
  • High-ripple current filtering — Filtering and decoupling where capability for 7.10 A (120 Hz) and 9.94 A (10 kHz) ripple currents is required.
  • Compact equipment designs — Suited for equipment downsizing where a high-capacitance aluminum electrolytic with a compact φ51 × 65 mm footprint is needed.

Unique Advantages

  • High-voltage bulk capacitance: 400 V rating combined with 1.2 mF nominal capacitance provides substantial charge storage for 400 V power rails.
  • Robust high-current termination: Screw terminals and M5 nominal bolt sizing enable secure, low-impedance connections for high-ripple applications.
  • Proven endurance at elevated temperature: 2000-hour rated life at 85°C when subjected to rated ripple current supports reliable long-term operation in warm environments.
  • Measurable electrical performance: Specified tan δ (0.25 at 20°C, 120 Hz) and defined leakage current (2070 µA) allow predictable thermal and loss budgeting in designs.
  • Electrical isolation assurance: Insulation resistance >100 MΩ at DC 500 V and AC 2500 V proof testing reduce risk of terminal-to-bracket breakdown.
  • Production-ready packaging: Cardboard packing and mass-production status simplify procurement and integration into manufacturing workflows.
