LGU1E333MELC

The LGU1E333MELC is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LGU series, offering 33,000 µF capacitance at a 25 V rating in a radial, snap-in can (φ35 × 50 mm). It is designed for general-purpose applications that require large bulk capacitance combined with defined ripple-current capability and durability at elevated temperatures.

Key value propositions include a 105°C rated operating range with 3,000 hours endurance under rated ripple current, measurable loss-angle characteristics (tan δ), and tray packaging for production handling.

Key Features

• Capacitance & Tolerance — 33,000 µF (33 mF) with tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage — 25 V DC.
• Snap-in Radial Can — Snap-in terminal mounting for secure through-hole installation; package dimensions φ35 × 50L mm.
• High-Temperature Endurance — Specified life of 3,000 hours at 105°C when subjected to DC bias plus rated ripple current.
• Ripple Current Ratings — Low-frequency ripple current: 5.5 A at 120 Hz; high-frequency ripple current: 6.325 A at 50 kHz.
• Loss Angle (tan δ) — tan δ = 0.4 measured at 20°C, 120 Hz (rated voltage 25 V condition).
• Leakage Current — 2,720 µA (specified value).
• Operating Temperature Range — -40°C to 105°C.
• Production & Compliance — RoHS compliant and in mass production; packaged in trays for handling.

Typical Applications

• General-purpose power filtering — Bulk capacitance and ripple-current capability for smoothing DC rails at 25 V.
• High-temperature systems — Use where sustained operation up to 105°C and proven 3,000-hour endurance are required.
• Through-hole, chassis-mounted designs — Snap-in radial can provides mechanical stability for secure mounting in power assemblies.

Unique Advantages

• Sustained high-temperature performance: 3,000 hours endurance at 105°C under rated ripple current supports long service intervals in elevated-temperature environments.
• High bulk capacitance in a compact can: 33,000 µF in a φ35 × 50 mm package reduces the number of components needed for bulk storage.
• Defined ripple handling: Rated for 5.5 A at 120 Hz and 6.325 A at 50 kHz, enabling predictable filtering performance across low and high frequencies.
• Measured electrical characteristics: Specified tan δ (0.4 at 20°C, 120 Hz) and leakage current (2,720 µA) provide quantifiable parameters for design margins.
• Assembly-ready packaging: Snap-in terminal and tray packing streamline through-hole mounting and production handling.
• Regulatory readiness: RoHS compliant and available in mass production for volume deployment.
