Overview of LNY2G392MSEFBN – Screw Terminal Aluminum Electrolytic Capacitor, 3900 µF, 400 V

The LNY2G392MSEFBN is a screw-terminal aluminum electrolytic capacitor designed for high-capacitance, high-voltage DC applications. As a member of the LNY series, it offers a compact radial can package with screw terminals and is suited for equipment downsizing where reliable bulk capacitance is required.

With a rated capacitance of 3900 µF at 400 V, an operating temperature range of −40 °C to +85 °C, and a specified load life under ripple current, this capacitor is intended for general-purpose power applications demanding sustained performance under ripple-loading conditions.

Key Features

  • Capacitance & Voltage — 3900 µF nominal capacitance with a 400 V rated voltage provides substantial energy storage for high-voltage DC circuits; capacitance tolerance is ±20% (120 Hz, 20 °C).
  • High Ripple Endurance — Specified ripple current capability of 13.8 A at 120 Hz and 19.32 A at 10 kHz supports sustained ripple-loading conditions encountered in power electronics.
  • Load Life — Designed for 2000 hours of rated ripple-current application at 85 °C, providing predictable life performance under elevated-temperature ripple stress.
  • Temperature Range — Rated for operation from −40 °C to +85 °C to cover a broad range of industrial and equipment environments.
  • Mechanical & Mounting — Radial can with screw terminals (M5 bolt nominal for φ51 size) enables secure, low-resistance connections for panel or chassis mounting; nominal dimensions L: 17 cm × D: 5.1 cm (φ51 × 170 mm length).
  • Polarized Design — Polar aluminum electrolytic construction for DC applications requiring polarized bulk capacitance.
  • RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863), meeting environmental substance restrictions.

Typical Applications

  • High-voltage DC filtering — 400 V rating and 3900 µF capacitance provide bulk energy storage and smoothing in high-voltage DC circuits.
  • Power supply decoupling — Screw-terminal mounting and high ripple-current capability make it suitable for DC bus decoupling and bulk filtering in compact power assemblies.
  • Equipment designed for downsizing — Part of the LNY series aimed at enabling equipment size reduction while retaining high capacitance and reliable ripple performance.

Unique Advantages

  • High-voltage bulk capacitance — 3900 µF at 400 V supplies substantial stored energy for DC systems without requiring series-parallel stacking.
  • Engineered for ripple stress — Rated ripple-current values at both low and high frequencies help maintain performance under real-world AC ripple loads.
  • Predictable lifetime under load — 2000-hour load-life specification at 85 °C with rated ripple current provides measurable reliability for thermal and ripple-stressed designs.
  • Robust screw-terminal connections — M5-compatible screw terminals and radial can format simplify secure mechanical and electrical integration into assemblies.
  • Wide operating temperature range — −40 °C to +85 °C rating supports deployment across varied industrial environments.
  • RoHS compliance — Meets current directive requirements for restricted substances.
