LGN2W331MELC35

The LGN2W331MELC35 is an aluminum electrolytic capacitor in a snap‑in terminal, radial can package designed for general‑purpose power applications. It delivers 330 µF capacitance at a 450 V rated voltage with polarization and a compact 3.5 × 3.5 cm footprint.

Built for elevated operating conditions, this part is specified for continuous operation up to 105°C and is designed to withstand rated ripple current for 3000 hours at 105°C, making it suitable for equipment requiring high temperature endurance and stable filtering performance.

Key Features

• Capacitance and Voltage — 330 µF nominal capacitance with a 450 V rated voltage for high‑voltage DC filtering and smoothing.
• Snap‑In Radial Can Package — Snap‑in terminal mounting for robust mechanical retention and straightforward board installation.
• High Temperature Endurance — Rated for operation up to 105°C with endurance specified as 3000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Capability — Rated ripple current of 1.38 A at 120 Hz and 1.973 A at 100 kHz, supporting typical power supply ripple handling requirements.
• Compact Size — One rank smaller case size than the LGU series; physical dimensions L: 3.5 × D: 3.5 cm with a seated height maximum of 1.378 inches.
• Electrical Characteristics — Capacitance tolerance ±20%; leakage current after 5 minutes at 20°C meets I ≤ 3/√C (µA); tan δ limits up to 0.20 depending on rated voltage.
• Environmental Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering — Bulk smoothing and ripple attenuation in DC power supplies and high‑voltage regulators where a 450 V rating is required.
• Industrial power modules — Energy buffering and decoupling in industrial converters and power control equipment operating at elevated temperatures.
• High‑voltage DC circuits — Bulk capacitance for DC link, smoothing, and energy storage in systems that demand sustained performance at 105°C.

Unique Advantages

• Extended high‑temperature life — 3000 hours rated endurance at 105°C provides predictable long‑term behavior under sustained thermal stress.
• High voltage capability — 450 V rating enables deployment in higher DC voltage stages without component stacking.
• Measured ripple performance — Specified ripple currents at both low and high frequency (120 Hz and 100 kHz) help designers match capacitor selection to system ripple profiles.
• Compact, board‑friendly form factor — Snap‑in radial can and a smaller case size than the LGU series reduce board area while maintaining performance.
• Standards‑based electrical limits — Defined leakage current formula and tan δ limits provide verifiable acceptance criteria during qualification and incoming inspection.
• RoHS compliant — Conforms to current RoHS requirements for regulated substances.
