Overview of LGG2G181MELZ30 – 180 µF, 400 V Snap‑In Aluminum Electrolytic Capacitor

The LGG2G181MELZ30 is an aluminum electrolytic capacitor in Nichicon’s LGG series, configured with a snap‑in terminal radial can. It delivers 180 µF nominal capacitance at a 400 V rated voltage with ±20% tolerance and is supplied in tray packing for mass production.

Designed for compact, high‑voltage applications, this snap‑in capacitor combines a small φ22 × 30 mm case size with endurance to 105°C (2000 hours), controlled loss (tan δ 0.15 at 20°C, 120 Hz), and defined ripple handling for both low and high frequency environments.

Key Features

  • Capacitance & Voltage — 180 µF nominal capacitance with a 400 V rated working voltage and ±20% tolerance, suitable where high DC voltage capacitance is required.
  • Snap‑In Radial Package — Snap‑in terminal, radial can package (φ22 × 30 mm) for secure mounting and simplified assembly in chassis or PCB snap‑in designs.
  • Low Loss (tan δ) — tan δ ≤ 0.15 measured at 20°C and 120 Hz, providing predictable dissipation characteristics for stable AC performance.
  • Ripple Current Capability — 730 mA ripple current at 120 Hz and 1.044 A ripple current at 100 kHz, enabling use under both low‑ and high‑frequency ripple conditions.
  • Leakage Current — Specified leakage current of 800 µA, measured after rated voltage application at 20°C.
  • High‑Temperature Endurance — Rated for 2000 hours at 105°C under DC bias plus rated ripple current, with defined post‑test limits for capacitance, tan δ and leakage current.
  • Operating Temperature Range — –25°C to +105°C for the 400 V products in the LGG series, matching thermal requirements for many high‑voltage designs.
  • RoHS Compliant — Conforms to RoHS requirements.

Typical Applications

  • General‑purpose high‑voltage systems — Suitable where a 400 V, 180 µF snap‑in capacitor is needed for DC bus or energy storage in general equipment.
  • Compact equipment designs — The LGG series is specified as an ultra‑smaller‑sized snap‑in type, making this part appropriate for designs targeting reduced case size.
  • High‑temperature environments — With a rated operating range to 105°C and 2000 h endurance at 105°C, this capacitor addresses applications that require prolonged elevated‑temperature reliability.
  • Chassis or PCB snap‑in mounting — Snap‑in radial can format provides robust mechanical mounting for assemblies that prefer snap‑in terminals.

Unique Advantages

  • Compact, high‑voltage package: 180 µF at 400 V in a φ22 × 30 mm snap‑in can supports smaller footprint designs without sacrificing voltage capability.
  • Balanced AC performance: Low tan δ (0.15 at 20°C, 120 Hz) combined with specified ripple ratings at 120 Hz and 100 kHz gives predictable behavior across common ripple conditions.
  • Proven thermal endurance: 2000 hours at 105°C under rated conditions delivers measurable longevity for elevated‑temperature applications.
  • Defined leakage and stability: 800 µA leakage current spec and endurance/shelf‑life limits ensure consistent recovery and performance after voltage treatment.
  • Industry compliance: RoHS‑compliant construction supports regulatory requirements for lead‑free assemblies.
  • Production ready: Supplied in tray packing and indicated for mass production to support volume manufacturing workflows.

Why Choose LGG2G181MELZ30?
