LGY1J332MELZ45

The LGY1J332MELZ45 is a Nichicon LGY series aluminum electrolytic capacitor in a snap-in terminal configuration, offering 3300 µF (3.3 mF) capacitance at 63 V. It is a long-life, radial can designed for general-purpose power applications and industrial power supplies, including ballast circuits, where dependable bulk capacitance and sustained ripple handling are required.

Designed for continuous operation across a wide temperature range, this part combines high-capacitance energy storage with snap-in mounting for secure assembly in mass-production environments (tray packing).

Key Features

• Capacitance & Rated Voltage — 3300 µF (3.3 mF) nominal capacitance with a rated voltage of 63 V and tolerance of ±20% at 120 Hz, 20°C.
• Snap-in Package & Mounting — Radial, can-style snap-in terminals for robust board retention and straightforward mechanical assembly in high-volume production.
• High Temperature Long Life — Rated for operation from −40°C to +105°C with endurance specified as 5000 hours at 105°C under rated ripple and DC bias.
• Ripple Current Capability — Rated ripple current of 2.2 A at 120 Hz and 2.53 A at 50 kHz; frequency coefficients are provided for scaling ripple with frequency (e.g., 120 Hz = 1.00, 50 Hz = 0.88, 1 kHz = 1.15).
• Reliability Parameters — Endurance condition: after 5000 hours at 105°C with rated ripple the capacitor meets specified limits (capacitance change within ±25%, tan δ ≤ 250% of initial spec, leakage ≤ initial value). Leakage current follows I ≤ 3√(C·V) µA after 5 minutes at 20°C.
• Physical Size — Compact footprint: diameter φ22 mm × length 45 mm (L: 4.5 × D: 2.2 cm), suitable where high bulk capacitance must fit a confined layout.
• RoHS Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing in industrial converters where long-term ripple endurance at elevated temperatures is required.
• Ballasts — Suitable for ballast circuits that require stable capacitance and reliable operation under continuous stress at elevated temperatures.
• General-Purpose Power Filtering — Use for DC bus smoothing and decoupling in power conversion systems and other general-purpose power electronics.

Unique Advantages

• Long-life assurance: Endurance rated for 5000 hours at 105°C ensures sustained performance in high-temperature duty cycles.
• Designed for ripple-heavy environments: Specified ripple current ratings at multiple frequencies and a published frequency coefficient table allow engineers to size capacitors confidently for expected operating conditions.
• Secure, assembly-friendly mounting: Snap-in terminals provide robust board retention for reliable mechanical and electrical connection in mass-production builds.
• Compact high-capacitance footprint: φ22 × 45 mm form factor delivers 3300 µF of bulk capacitance while keeping PCB real estate minimized.
• Clear reliability metrics: Defined limits for capacitance change, tan δ, and leakage after endurance testing make qualification and lifetime planning more predictable.
• RoHS-compliant manufacturing: Meets RoHS requirements for environmentally constrained projects and procurement specifications.
