Overview of LASW6121MELZ35ZB – Snap‑in Aluminum Electrolytic Capacitor, 420 V, 120 µF

The LASW6121MELZ35ZB is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LAS series. It delivers 120 µF capacitance at a 420 V rating in a compact radial can (φ22 × 35 mm) designed for general‑purpose power applications.

Engineered for high ripple environments and extended operation at elevated temperature, this part supports 2000 hours endurance at 105°C, enhanced safety features for abnormal voltage conditions, and RoHS compliance—making it suited to equipment that experiences voltage fluctuations and sustained thermal stress.

Key Features

  • Electrical Rating: 120 µF capacitance with ±20% tolerance at 120 Hz, 20°C, and a 420 V rated voltage—providing stable bulk energy storage for high‑voltage circuits.
  • High Temperature Endurance: Qualified for 2000 hours at 105°C under rated ripple current conditions, supporting reliable long‑term operation in hot environments.
  • Ripple Current Performance: Low‑frequency ripple current 750 mA (120 Hz) and high‑frequency ripple current 862.5 mA (10 kHz), with frequency coefficients defined by the LAS series to account for increased ripple capability at higher frequencies.
  • Loss and Leakage: Low loss tangent (tan δ ≤ 0.20 at 120 Hz, 20°C) and a measured leakage current of 670 µA, enabling predictable dissipation and leakage behavior in power designs.
  • Snap‑in Radial Package: Snap‑in terminal can (φ22 × 35 mm) for secure board mounting and compact installation; packaged in trays for production handling.
  • Safety Features: LAS series includes improved safety for abnormally excessive voltage and a pressure relief vent designed to operate under fault conditions without flame or dangerous dispersion.
  • Compliance: RoHS compliant and offered in a mass‑production status for consistent supply availability.

Typical Applications

  • General‑purpose power equipment: Bulk energy storage and smoothing in high‑voltage power systems where 420 V rating and substantial ripple tolerance are required.
  • Industrial electronics: Use in equipment exposed to voltage fluctuations or sustained elevated temperatures, leveraging the 2000 h endurance at 105°C.
  • Power conversion modules: Suitable for high‑voltage sections of converters and supplies that demand snap‑in mounting and reliable ripple handling.

Unique Advantages

  • Extended high‑temperature life: 2000 hours endurance at 105°C ensures predictable aging and stability in thermally demanding installations.
  • High‑voltage capability: 420 V rating provides headroom for 400–450 V class power systems and fluctuating supply conditions.
  • Robust ripple handling: Defined low‑ and high‑frequency ripple currents (750 mA at 120 Hz; 862.5 mA at 10 kHz) and frequency coefficients help designers size for real operating spectra.
  • Compact snap‑in form factor: φ22 × 35 mm radial can minimizes board area while providing a secure mechanical and electrical connection.
  • Built‑in safety measures: Pressure relief vent and LAS series improvements for abnormal voltage reduce the risk of dangerous failure modes under fault conditions.
  • Manufacturing readiness: Tray packaging and mass‑production status support streamlined procurement and assembly processes.
