LGNW6680MELY25

The LGNW6680MELY25 is an aluminum electrolytic capacitor in Nichicon’s LGN series, featuring a snap-in terminal, radial can package and a compact φ20 × 25 mm footprint. It delivers 68 µF at a 420 V voltage rating with a -20% to +20% tolerance and is intended for general-purpose electronic applications.

Key value propositions include high-voltage capability, specified ripple current performance across low and high frequencies, extended endurance at elevated temperature, and RoHS compliance for production usage.

Key Features

• Electrical Performance — 68 µF capacitance with a 420 V rated voltage and capacitance tolerance of -20% to +20%, providing predictable bulk capacitance for medium-voltage designs.
• Dissipation Factor — tanδ (DF) of 0.15 measured at 20°C and 120 Hz for controlled loss characteristics under normal operating conditions.
• Ripple Current Ratings — Low-frequency ripple current 500 mA at 120 Hz and high-frequency ripple current 715 mA at 100 kHz, specified to help manage AC stress across frequency ranges.
• Leakage Current — Specified leakage current of 500 µA after voltage application, useful for predictable standby and leakage behavior.
• Thermal Endurance — Rated operating temperature range of -25°C to 105°C with a life/endurance rating of 3000 hours at 105°C under rated ripple conditions.
• Package & Mounting — Snap-in terminal type in a radial can (φ20 × 25 mm) for secure mechanical mounting; product is supplied in tray packing and is in mass production.
• Standards & Compliance — RoHS compliant; part of the LGN series which is specified for 3000 hours’ ripple endurance at 105°C.

Typical Applications

• General-purpose electronics — Designed for applications that require 68 µF at 420 V in a compact snap-in form factor.
• Power supply modules — Suitable where a 420 V rated capacitor with specified ripple endurance at 105°C is required for smoothing or energy buffering.
• Industrial assemblies — Snap-in radial can and tray packing simplify mechanical integration and production handling in assembly environments.

Unique Advantages

• High-voltage capability: 420 V rating supports medium-voltage circuit requirements without needing larger form factors.
• Extended high-temperature life: 3000 hours at 105°C under rated ripple current reduces replacement frequency for applications exposed to elevated temperatures.
• Frequency-aware ripple specs: Separate ripple current ratings at 120 Hz and 100 kHz provide clear expectations for performance across low and high frequency conditions.
• Compact snap-in package: φ20 × 25 mm radial can with snap-in terminals offers secure mounting and smaller board footprint compared with larger cases.
• Production-ready supply: Mass production status and tray packing support volume procurement and automated assembly processes.
