LGG2G331MELA40

The LGG2G331MELA40 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGG series, offering 330 µF capacitance at a 400 V rating. It is a compact, radial can (φ25 × 40 mm) designed for general‑purpose electronic and power applications that require high‑voltage bulk capacitance in a snap‑in PCB mounting format.

Engineered for elevated temperature operation, this device is specified for use up to 105°C with documented endurance, and is supplied in tray packing for mass production environments. The part is RoHS compliant.

Key Features

• Capacitance & Voltage — 330 µF rated at 400 V provides high‑voltage bulk capacitance in a single component.
• High‑temperature endurance — Rated for operation up to 105°C with an endurance specification of 2000 hours at 105°C when subjected to D.C. bias plus rated ripple current.
• Compact snap‑in package — Radial, can-type snap‑in mounting in a φ25 × 40 mm package supports secure PCB installation and tray packing for production.
• Ripple current capability — Rated ripple currents of 1.15 A at 120 Hz and 1.645 A at 100 kHz for handling AC content on the DC bus.
• Electrical stability & loss — Capacitance tolerance ±20% (at 120 Hz, 20°C); tan δ maximum 0.15 measured at 120 Hz, 20°C for the applicable voltage range.
• Leakage current specification — Leakage defined as I ≤ 3√CV (µA) after 5 minutes’ application of rated voltage at 20°C (C: µF, V: volts), enabling predictable design margining.
• Polarized, snap‑in terminals — Polarized electrolytic construction with snap‑in terminals for robust mechanical retention on PCBs.
• Regulatory compliance — RoHS compliant.

Typical Applications

• General‑purpose electronics — Intended for general‑purpose circuits requiring 330 µF at 400 V.
• High‑temperature power circuits — Suited for applications that must maintain capacitance and reliability at up to 105°C with long endurance.
• Production PCB assemblies — Snap‑in radial can and tray packing support repeatable assembly and high‑volume manufacturing.

Unique Advantages

• High‑voltage bulk capacitance: 330 µF at 400 V supplies substantial energy storage in a single component, simplifying BOM for high‑voltage designs.
• Compact, space‑efficient package: φ25 × 40 mm snap‑in can offers a smaller case profile within the LGG series, helping reduce board area used for bulk capacitors.
• Designed for elevated temperatures: 105°C rating and 2000 hours endurance specification provide predictable long‑term performance under thermal stress.
• Defined ripple performance: Rated ripple currents at both low and high frequencies (1.15 A @120 Hz, 1.645 A @100 kHz) support designs with varying ripple spectra.
• Predictable leakage behavior: Leakage current limited by the datasheet formula (I ≤ 3√CV) after voltage application, enabling reliable bias current budgeting.
• RoHS compliant: Meets RoHS requirements for environmental regulatory alignment.
