Overview of LGN2W121MELA30 – 450 V, 120 µF Snap‑In Aluminum Electrolytic Capacitor

The LGN2W121MELA30 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGN series, rated for 450 V and 120 µF. It is a smaller‑sized, high‑voltage snap‑in can designed for general‑purpose applications that require elevated temperature performance and reliable ripple handling.

Key value comes from its 105°C endurance capability with rated ripple current, compact radial can snap‑in package, and RoHS compliance for regulatory alignment.

Key Features

  • Capacitance & Voltage — 120 µF nominal capacitance with a 450 V rated voltage and capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
  • High‑Temperature Endurance — Rated operating temperature range −25°C to +105°C with demonstrated endurance of 3000 hours at 105°C under D.C. bias plus rated ripple current.
  • Ripple Current Performance — Rated ripple current of 720 mA at 120 Hz and 1.03 A at 100 kHz, specified for sustained operation at rated conditions.
  • Package & Mounting — Radial snap‑in can (snap‑in terminal type) for secure board retention and straightforward assembly in power modules and frames.
  • Electrical Stability — Leakage current specification I ≤ 3/√(C) µA after 5 minutes at 20°C; tan δ limit for 450 V class per datasheet and defined impedance behavior at low temperature (Z(−25°C)/Z(+20°C) up to 8 for 350–600 V range).
  • Compact Size — One rank smaller case than the LGU series and physical dimensions L: 3 × D: 2.5 cm with a seated height spec (max) provided for board layout considerations.
  • Regulatory Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

  • General‑purpose electronic circuits — Specified by the manufacturer for general‑purpose use where a 450 V, high‑temperature snap‑in electrolytic capacitor is required.
  • General‑purpose power modules — Applicable in board‑level power assemblies that require sustained ripple handling at elevated temperatures.
  • General‑purpose industrial equipment — Suited to general‑purpose installations demanding 105°C rated electrolytic capacitance and RoHS compliance.

Unique Advantages

  • Elevated temperature endurance: 3000 hours at 105°C under rated ripple conditions provides predictable aging characteristics for long‑duration operation.
  • High‑voltage capability: 450 V rating supports designs that require higher DC bus voltage handling within a single component.
  • Strong ripple performance: Defined ripple current ratings at both 120 Hz and 100 kHz allow selection based on supply frequency and switching characteristics.
  • Space‑efficient form factor: One rank smaller case than LGU delivers a more compact solution while maintaining snap‑in mounting and robust electrical performance.
  • Measurable electrical limits: Clear leakage current, tan δ, and low‑temperature impedance specifications make it easier to predict behavior during design and qualification.
  • RoHS compliant: Meets RoHS directive requirements for material compliance in modern electronic assemblies.
