LGY1C333MELB45

The LGY1C333MELB45 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGY long‑life assurance series. It provides a polarized, high‑capacitance solution (33 mF at 16 V) in a radial can snap‑in package suitable for robust board mounting.

Engineered for industrial power systems, this capacitor is optimized for applications requiring reliable performance under sustained ripple current and elevated temperature conditions—rated for operation from −40°C to +105°C with a demonstrated 5000‑hour endurance at 105°C under rated ripple current.

Key Features

• Long‑life endurance — Designed to withstand 5000 hours of DC bias plus rated ripple current at 105°C; capacitance change and leakage remain within the endurance limits after test.
• High ripple capability — Rated ripple currents: 4 A at 120 Hz and 4.6 A at 50 kHz, with frequency coefficient data available in the LGY series specifications.
• Wide operating temperature — Specified category temperature range from −40°C to +105°C for use across demanding industrial environments.
• Electrical characteristics — Capacitance 33 mF with ±20% tolerance and polarization; leakage current specified as I ≤ 3√CV (μA) after 5 minutes at 20°C.
• Loss tangent (tan δ) — tan δ maximum of 0.50 at 16 V (measured at 120 Hz, 20°C), supporting predictable ESR behavior for power applications.
• Snap‑in radial can package — Radial, can‑type snap‑in mounting for secure mechanical and electrical board attachment; physical size L: 4.5 × D: 3 cm simplifies board layout planning.
• RoHS compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863), suitable for designs requiring restricted‑substance compliance.

Typical Applications

• Industrial power supplies — Bulk smoothing and energy storage where long life and sustained ripple handling at elevated temperatures are required.
• Ballast applications — Suitable for ballast circuits that demand dependable performance over extended operating periods.
• General purpose power systems — Applications requiring a polarized, high‑capacitance snap‑in solution for robust board mounting and reliable filtering.

Unique Advantages

• Proven long‑life capability — 5000‑hour endurance at 105°C under rated ripple current reduces the risk of premature replacement in high‑stress environments.
• High ripple current handling — Rated ripple specs at both low and high frequencies (4 A at 120 Hz; 4.6 A at 50 kHz) enable use in power stages with significant AC content.
• Wide temperature range — −40°C to +105°C rating supports deployment across a broad range of industrial climate conditions.
• Predictable electrical behavior — Clear specifications for leakage current and tan δ (16 V) allow accurate margining in power‑supply designs.
• Board‑friendly snap‑in package — Radial snap‑in can simplifies mechanical retention and layout for power assemblies.
• Regulatory compliance — RoHS conformity aligns with restricted‑substance requirements for commercial and industrial products.
