LGY1J332MELA35

The LGY1J332MELA35 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGY series, offering 3.3 mF capacitance at a 63 V rating. It is a long‑life, radial can device designed for robust bulk energy storage and smoothing in industrial and general‑purpose power applications.

Key value comes from its 5000‑hour endurance at 105°C, high ripple current capability, and a wide operating temperature range of −40°C to 105°C—attributes that support reliable performance in demanding power supply and ballast environments.

Key Features

• Capacitance & Voltage — Rated capacitance 3.3 mF (3300 µF) with a tolerance of ±20% at 120 Hz, 20°C; rated voltage 63 V.
• Long‑life Endurance — Specified for 5000 hours at 105°C with DC bias and rated ripple current applied; after test the part meets defined limits for capacitance change, tan δ and leakage current.
• High Ripple Current — Rated ripple current 2200 mA at 120 Hz (low frequency) and 2530 mA at 50 kHz (high frequency) to support high‑duty filtering and smoothing tasks.
• Low Loss (tan δ) — Maximum tan δ of 0.25 at 20°C, 120 Hz for the 63 V rating, giving predictable dissipation characteristics for thermal and loss budgeting.
• Leakage Current — Specified leakage current of 1360 µA (after rated voltage applied for 5 minutes at 20°C); datasheet also references the standard leakage formula I ≤ 3√(C·V).
• Temperature Range — Operating from −40°C to +105°C, suitable for industrial ambient conditions.
• Package & Mounting — Snap‑in terminal radial can, size φ25 × 35 mm (L: 3.5 × D: 2.5 cm), tray packing and mass production availability for board‑level installation.
• Frequency Coefficient — Datasheet provides a frequency coefficient for rated ripple current (e.g., 0.88 at 50 Hz, 1.00 at 120 Hz, rising to 1.15 at 1 kHz and above) to aid ripple derating across frequencies.
• RoHS Compliant — Manufactured in compliance with the RoHS directive as stated in the datasheet content.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and energy storage where long‑term reliability and high ripple handling are required.
• Ballast and Lighting Systems — Designed for ballast applications highlighted in the series documentation, offering stable performance under continuous ripple load.
• Power Conversion & Filtering — Suitable for DC‑link, filtering and bulk decoupling in converters and inverters operating up to 63 V.
• General‑Purpose Industrial Electronics — Bulk capacitance and smoothing for control systems, drives, and instrumentation that demand extended endurance at elevated temperatures.

Unique Advantages

• Designed for long service life — 5000 hours endurance at 105°C supports predictable lifecycle planning in industrial designs.
• Handles significant ripple — High rated ripple currents at both low and high frequencies reduce the need for paralleling multiple capacitors.
• Thermal and loss predictability — Specified tan δ and leakage figures enable accurate thermal and performance budgeting during system design.
• Robust operating range — −40°C to +105°C operation covers a wide span of industrial environments.
• Service‑friendly snap‑in package — Radial snap‑in can simplifies board mounting and replacement in production and field service scenarios.
• Compliance and production readiness — RoHS compliance and tray packing support regulatory and high‑volume manufacturing needs.
