LGJ2W680MELA20

The LGJ2W680MELA20 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGJ series, designed for high‑voltage, general‑purpose applications. It delivers 68 µF at a 450 V rating in a low‑profile φ25 × 20 mm radial can optimized for secure snap‑in mounting and tray packing for volume production.

Engineered for demanding thermal environments, this part supports operation from −25°C to 105°C with an endurance specification of 3000 hours at 105°C, combining high voltage capability with defined ripple and leakage characteristics for reliable power‑electronics use.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance with a 450 V rated voltage and a capacitance tolerance of ±20% (120 Hz, 20°C).
• High‑Temperature Endurance — Rated for continuous operation to 105°C with a specified lifetime of 3000 hours at 105°C.
• Ripple Current Performance — Specified ripple capabilities include 670 mA at 120 Hz (low frequency) and 958.1 mA at 50 kHz (high frequency), enabling defined AC stress handling in real circuits.
• Leakage Current — Initial leakage current specified at approximately 520 µA, consistent with the product's rated capacitance and voltage.
• Low‑Profile, Snap‑In Package — φ25 × 20 mm radial can with snap‑in terminals for secure board mounting and simplified assembly; supplied in tray packing for mass production.
• Electrical Stability — For 400–450 V ratings, low‑temperature impedance stability is specified (Z(−25°C)/Z(+20°C) = 8), and tan δ (loss factor) is specified up to 0.20 at 120 Hz, 20°C.

Typical Applications

• General‑Purpose Power Electronics — Suitable where a robust, high‑voltage electrolytic capacitor is required for bulk capacitance and energy storage in general‑purpose designs.
• Industrial Equipment — Applicable to industrial power modules and control equipment that require a high‑voltage, high‑temperature rated radial capacitor with snap‑in mounting.
• Power Conversion Modules — Use in power conversion and conditioning modules where specified ripple handling and predictable leakage are required.

Unique Advantages

• High Voltage Capability: 450 V rating supports demanding high‑voltage circuits while keeping footprint small.
• Defined Ripple Ratings: Explicit ripple current values at 120 Hz and 50 kHz allow designers to predict thermal and lifetime performance under AC stress.
• Compact Low‑Profile Form: φ25 × 20 mm package reduces board height without sacrificing capacitance, aiding dense power assemblies.
• Thermal Endurance: 3000 hours at 105°C provides a documented life metric for high‑temperature deployments.
• Snap‑In Mounting & Tray Packing: Snap‑in terminals provide mechanical stability; tray packing supports efficient handling in production lines.
• Measured Electrical Stability: Specified tan δ and low‑temperature impedance behavior give predictable performance across temperature and frequency ranges.
