LGJ2E221MELA20

The LGJ2E221MELA20 is a snap‑in terminal aluminum electrolytic capacitor designed for 250 V systems. It is a low‑profile, radial can device sized φ25 × 20 mm and rated for continuous operation to 105°C, intended for general‑purpose power applications.

Engineered to provide bulk capacitance and ripple handling in compact assemblies, this part combines a 220 µF capacitance with snap‑in mounting and endurance characteristics suited to production environments.

Key Features

• Capacitance & Voltage — 220 µF rated at 250 V with ±20% tolerance, providing predictable bulk energy storage for mid‑voltage circuits.
• High Temperature Endurance — Rated for operation from −40°C to +105°C with a specified life of 3000 hours at 105°C.
• Snap‑in Radial Can Package — φ25 × 20 mm low‑profile can with snap‑in terminals for secure, quick mounting in tray‑packed mass production.
• Ripple Current Capability — 920 mA at 120 Hz (low frequency) and 1.38 A at 50 kHz (high frequency) to support smoothing and decoupling under dynamic loads.
• Leakage Current — Specified leakage current of 700 µA, allowing designers to account for standby and quiescent currents.
• Polarized Electrolytic — Standard polarized construction for DC bulk and filtering applications.

Typical Applications

• Power supply filtering — Bulk smoothing and ripple reduction in mid‑voltage AC/DC and DC/DC supplies.
• Industrial electronics — General‑purpose energy storage and decoupling in control and power modules operating up to 105°C.
• Power conversion — Support for DC link and intermediate bus capacitors in converter and inverter circuits that require high ripple handling.

Unique Advantages

• Compact low‑profile form factor: φ25 × 20 mm can minimizes board area while delivering 220 µF at 250 V.
• Robust high‑temperature rating: 3000 hours at 105°C provides predictable end‑of‑life performance for demanding thermal environments.
• Frequency‑aware ripple capability: Rated ripple current of 920 mA at 120 Hz and 1.38 A at 50 kHz, with frequency coefficients that allow higher ripple handling at higher frequencies.
• Production‑ready packaging: Tray packing and snap‑in terminals simplify automated assembly and mechanical retention for volume builds.
• Clear electrical parameters: Specified leakage current (700 µA) and ±20% tolerance allow accurate power‑budget and tolerance planning.
