LLS2E221MELZ

The LLS2E221MELZ is a Nichicon LLS series aluminum electrolytic capacitor in a snap‑in terminal radial can. It delivers 220 µF capacitance at a 250 V rating in a compact φ22 × 25 mm package and is polarized for DC applications.

Engineered for general‑purpose power electronics, the LLS2E221MELZ combines a long endurance profile — 3,000 hours at 85 °C under rated ripple conditions — with RoHS compliance and defined ripple current ratings for reliable performance in sustained operating environments.

Key Features

• Electrical Specification — 220 µF nominal capacitance with ±20% tolerance and a 250 V rated voltage for medium‑voltage DC applications.
• Endurance & Reliability — Rated to withstand 3,000 hours at 85 °C with DC bias plus rated ripple current applied, meeting the LLS series endurance criteria.
• Ripple Handling — Specified ripple current of 1.24 A at 120 Hz and 1.86 A at 50 kHz, enabling defined performance across common low and high frequency stress conditions.
• Operating Temperature Range — −40 °C to +85 °C, supporting a wide range of ambient conditions for general‑purpose electronic equipment.
• Package & Mounting — Snap‑in radial can (φ22 × 25 mm; length 2.5 cm × diameter 2.2 cm) for secure vertical mounting and convenient PCB insertion.
• Environmental Compliance — RoHS compliant per the LLS series declaration.

Typical Applications

• General‑Purpose Power Electronics — Use where 220 µF at 250 V is required for bulk capacitance or smoothing in DC circuits.
• Power Supply Filtering — Suitable for PCB-mounted filter stages that benefit from snap‑in mounting and defined ripple current capability.
• Industrial Equipment — Applicable where long endurance at elevated temperature (3,000 h at 85 °C) and a wide operating temperature range are needed.

Unique Advantages

• Long Endurance under Rated Ripple — 3,000‑hour endurance at 85 °C with applied rated ripple current reduces the need for frequent replacement in sustained duty applications.
• Defined Ripple Performance — Explicit ripple current ratings at 120 Hz and 50 kHz allow designers to size capacitance for both low‑ and higher‑frequency ripple environments.
• Compact Snap‑in Form Factor — φ22 × 25 mm radial can with snap‑in terminals provides a space‑efficient solution for vertical PCB mounting and secure retention.
• Wide Operating Range — −40 °C to +85 °C operation supports a variety of ambient conditions common in general‑purpose electronic systems.
• Regulatory Compliance — RoHS compliance supports designs targeting restricted‑substance requirements.
