Overview of LLS2V121MELZ – 350V Snap-in Aluminum Electrolytic Capacitor, 120 µF

The LLS2V121MELZ is a Nichicon LLS series aluminum electrolytic capacitor in a snap-in terminal can. It provides 120 µF capacitance at a 350 V rated voltage with polarized construction and a compact φ22 × 25L package.

Designed for general-purpose power applications, this snap-in capacitor delivers high-voltage energy storage, elevated ripple-current capability, and 3,000 hours endurance at 85°C—making it suitable where reliable DC filtering and bulk energy buffering are required.

Key Features

  • Rated Capacitance and Voltage — 120 µF capacitance rated at 350 V for high-voltage DC applications.
  • Snap-in Terminal Package — Radial, can-type snap-in construction for through-hole mounting and secure board attachment.
  • Endurance — 3,000 hours life at 85°C under rated ripple current conditions, with specifications restored at 20°C after test.
  • Ripple Current Capability — Low-frequency ripple current 1,040 mA at 120 Hz and high-frequency ripple current 1,487.2 mA at 50 kHz to support power supply smoothing and decoupling.
  • Electrical Loss — Tangent of loss angle (tan δ) of 0.15 maximum measured at 20°C and 120 Hz (typical for 350 V rating).
  • Leakage Current — Specified leakage current of 610 µA after voltage application at 20°C.
  • Operating Temperature — Rated for operation from –25°C to +85°C (350 V category temperature range).
  • RoHS Compliant — Meets RoHS directive requirements.
  • Compact Dimensions — Package diameter φ22 mm and length 25 mm for space-efficient placement.

Typical Applications

  • General-purpose power filtering — Bulk capacitance and ripple current handling for DC power supplies and smoothing stages.
  • Energy storage and buffering — High-voltage energy storage for intermediate DC link or hold-up functions within general-purpose equipment.
  • Power conversion stages — Support for decoupling and ripple attenuation where a 350 V rated aluminum electrolytic is required.

Unique Advantages

  • High-voltage capability: 350 V rating enables use in higher-voltage DC circuits without series stacking.
  • Robust ripple performance: 1,040 mA at 120 Hz and 1,487.2 mA at 50 kHz provide headroom for demanding ripple-current loads.
  • Long endurance at elevated temperature: 3,000 hours at 85°C supports sustained operation under rated ripple and bias conditions.
  • Compact, secure mounting: Snap-in radial can (φ22 × 25L) offers a space-efficient, board-secure solution for through-hole assemblies.
  • Measured low-loss behavior: tan δ ≤ 0.15 at 20°C/120 Hz for predictable ESR-related performance in AC conditions.
  • Regulatory compliance: RoHS-compliant construction aligns with modern environmental requirements.

Why Choose LLS2V121MELZ?

LLS2V121MELZ combines a high 350 V rating, substantial 120 µF capacitance, and elevated ripple-current capability in a compact snap-in aluminum can from Nichicon’s LLS series. Its 3,000-hour endurance at 85°C and controlled loss characteristics make it a reliable choice for general-purpose power filtering, energy storage, and decoupling tasks where stability over time and temperature is important.

This part is suited to designers and procurement teams seeking a mass-production-ready, RoHS-compliant electrolytic capacitor with proven endurance and clearly specified electrical characteristics for higher-voltage DC applications.
