Overview of LLS2V121MELY – 350 V, 120 µF Snap‑in Aluminum Electrolytic Capacitor

The LLS2V121MELY is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LLS series, rated at 350 V and 120 µF with a ±20% capacitance tolerance. It is a radial, can‑type snap‑in part designed for general‑purpose applications that require high‑voltage capacitance in a compact, board‑mountable package.

Key value propositions include high voltage capability, engineered ripple current handling at both low and high frequencies, 3000 hours endurance at 85°C, and RoHS compliance — making it suitable where reliable, long‑life electrolytic capacitance is required.

Key Features

  • Rated Voltage & Capacitance — 350 V rated voltage with 120 µF nominal capacitance and ±20% tolerance for general‑purpose high‑voltage designs.
  • Snap‑in, Radial Can Package — Snap‑in terminal mounting in a radial, can‑style package (size: φ20×30L; L: 3 × D: 2 cm) for secure PCB installation and mechanical stability.
  • Ripple Current Performance — 960 mA low‑frequency ripple current at 120 Hz and 1.373 A high‑frequency ripple current at 50 kHz, supporting both low and higher frequency power environments.
  • Leakage & Dissipation — Specified leakage current of 610 µA and a tangent of loss angle (tan δ) of 0.15 at 20°C, 120 Hz, providing predictable electrical behavior.
  • Endurance — Withstands 3000 hours of rated ripple current at 85°C per LLS series endurance specification.
  • Operating Temperature & Polarization — Rated for operation from −25°C to 85°C and is a polarized electrolytic capacitor.
  • Compliance & Packaging — RoHS‑compliant, supplied in tray packing, and listed as in mass production status.

Typical Applications

  • General‑Purpose Power Systems — Use where a 350 V, 120 µF snap‑in electrolytic capacitor with 3000 h endurance at 85°C is required for bulk capacitance or filtering in general‑purpose equipment.
  • High‑Voltage DC Link and Energy Storage — Appropriate for designs that require a 350 V rated polarized capacitor with defined ripple current capability at both 120 Hz and higher frequencies.
  • Industrial Electronics — Suitable for industrial or commercial equipment requiring RoHS‑compliant, board‑mounted snap‑in capacitors with predictable leakage and dissipation characteristics.

Unique Advantages

  • High Voltage Capability: 350 V rating enables use in higher‑voltage circuits requiring electrolytic bulk capacitance.
  • Dual‑Frequency Ripple Handling: Explicit ripple current specifications — 960 mA at 120 Hz and 1.373 A at 50 kHz — give designers clear data for both mains‑frequency and higher‑frequency applications.
  • Long Endurance at Elevated Temperature: Rated endurance of 3000 hours at 85°C under rated ripple current provides quantifiable life performance for thermal stress scenarios.
  • Predictable Electrical Losses: Low dissipation factor (tan δ = 0.15 at 20°C, 120 Hz) and specified leakage current (610 µA) enable reliable circuit modeling.
  • Board‑Mount Snap‑in Form Factor: Radial, snap‑in can in a compact φ20×30L package simplifies mounting and mechanical retention on PCBs.
  • Production‑Ready Supply: Tray packing and mass production status support volume assembly and procurement planning.
