LGR2E331MELZ40

The LGR2E331MELZ40 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGR Long Life series. It provides a polarized 330 µF capacitance at a 250 V rated voltage and is designed for long‑life operation at elevated temperatures.

Targeted at general‑purpose electronic applications, this component delivers extended endurance — specified for 10,000 hours under rated ripple current at 105°C — combined with snap‑in radial can mounting for secure PCB retention.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance.
• High‑Temperature Long Life — Rated for operation from –40°C to 105°C with endurance specified as 10,000 hours at 105°C under D.C. bias plus rated ripple current.
• Snap‑In Radial Can — Snap‑in terminal type for through‑hole PCB mounting and robust mechanical retention.
• Ripple Current Capability — Rated ripple current of 1.2 A at 120 Hz (low frequency) and 1.8 A at 50 kHz (high frequency).
• Polarized Design — Polarized aluminum electrolytic construction for bulk energy storage and decoupling in polarized circuits.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU,(EU)2015/863).
• Compact Profile — Package dimensions approximately L: 4 × D: 2.2 cm in a radial, snap‑in can form factor.

Typical Applications

• General Purpose — General‑purpose electronic designs requiring a polarized 330 µF, 250 V electrolytic capacitor with long life at elevated temperature.
• High‑Temperature Long‑Life Systems — Designs that require sustained operation at up to 105°C and endurance verified to 10,000 hours under rated ripple conditions.
• Snap‑In PCB Assemblies — Through‑hole assemblies where snap‑in radial cans provide secure mechanical mounting and straightforward PCB placement.

Unique Advantages

• Proven Long‑Life Specification — Endurance defined as 10,000 hours at 105°C under rated ripple current provides predictable aging behavior for longer maintenance intervals.
• High Voltage Capability — 250 V rating supports higher voltage applications within the LGR series’ rated range.
• Designed for Ripple Stress — Specified ripple current values (1.2 A at 120 Hz; 1.8 A at 50 kHz) and frequency coefficients from the series data help designers size capacitors for real‑world ripple profiles.
• Easy PCB Integration — Snap‑in radial can package simplifies placement and mechanical retention in through‑hole assemblies.
• Regulatory Compliance — RoHS compliance supports use in regions and projects with restricted substance requirements.
