LGU1C333MELC

The LGU1C333MELC is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGU series, offering 33,000 µF capacitance at a 16 V rating in a φ35 × 35 mm can. It is a polarized, radial can snap‑in package designed for general‑purpose applications that require high bulk capacitance and robust ripple endurance.

Engineered for demanding thermal and ripple environments, this capacitor withstands rated ripple current for 3000 hours at 105°C and is RoHS compliant, making it suitable for long‑life general‑purpose power designs that need reliable bulk energy storage and smoothing.

Key Features

• Capacitance & Voltage — 33,000 µF capacitance at a 16 V rated voltage, with a tolerance of ±20% (120 Hz, 20°C).
• Package & Mounting — Snap‑in radial can (φ35 mm diameter, 35 mm length) for secure chassis or PCB mounting in applications that require robust mechanical retention.
• High‑temperature Endurance — Endurance qualified for 3000 hours at 105°C with rated ripple current applied; capacitors meet endurance criteria after restoration to 20°C per datasheet requirements.
• Operating Temperature Range — Rated for –40°C to +105°C, supporting a wide ambient operating range for general‑purpose equipment.
• Rated Ripple Current — 4.27 A at 120 Hz and 4.91 A at 50 kHz, enabling effective ripple handling in power circuits within the specified voltage class.
• Frequency Coefficient Support — Frequency coefficient of rated ripple current (16–100 V range) increases with frequency up to 1.15 at 1 kHz and above, per the LGU series data.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power filtering — Bulk capacitance and smoothing where 33,000 µF at 16 V is required; suitable for reducing ripple and stabilizing DC rails in general‑purpose designs.
• Power supply energy storage — Provides energy buffering and ripple handling in power supplies that operate within the –40°C to +105°C range and require long endurance under rated ripple current.
• Industrial and equipment electronics — Snap‑in mounting and high ripple endurance make it a fit for industrial control and other equipment that needs robust bulk capacitors in a radial can package.

Unique Advantages

• Large bulk capacitance: 33,000 µF provides substantial energy storage for smoothing and hold‑up in low‑voltage power systems.
• Designed for sustained ripple: Rated ripple currents (4.27 A at 120 Hz, 4.91 A at 50 kHz) and 3000‑hour endurance at 105°C ensure long service life under continuous ripple stress.
• Snap‑in radial can: Mechanical snap‑in terminals simplify installation and provide secure retention for chassis or PCB mounting.
• Wide operating temperature: –40°C to +105°C rating supports use across a broad range of ambient conditions encountered in general‑purpose equipment.
• RoHS compliant: Meets applicable RoHS requirements for environmentally conscious designs.
