LGN2E471MELZ40

The LGN2E471MELZ40 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGN series, rated 470 µF at 250 V. It is a smaller-sized, radial can snap-in design intended for general-purpose applications that require sustained ripple handling and high-temperature endurance.

Key value propositions include a 105°C rated operating temperature, verified endurance under rated ripple conditions, and RoHS compliance — making it suited for designs where sustained performance at elevated temperatures is required.

Key Features

• Capacitance & Rated Voltage — 470 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance, providing predictable energy storage for DC-link or bulk applications.
• High-Temperature Endurance — Specified for operation up to 105°C with a guaranteed endurance of 3000 hours at 105°C under D.C. bias plus rated ripple current.
• Ripple Current Performance — Rated ripple current of 1.4 A at 120 Hz and 2.1 A at 100 kHz, supporting circuits with significant AC ripple components.
• Snap-in Radial Can Package — Snap-in terminal type in a radial can package with compact dimensions (L: 4.0 × D: 2.2 cm) and a one-rank smaller case size than the LGU series for space-constrained assemblies.
• Polarized Construction — Polarized electrolytic capacitor suitable for DC applications where polarity is defined.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-Purpose Power Electronics — Serves bulk energy storage and smoothing roles in designs that require 470 µF at 250 V with high ripple endurance.
• Industrial and Commercial Equipment — Useful where components must withstand elevated operating temperatures (up to 105°C) and continuous ripple stress.
• High-Ripple Circuits — Appropriate for circuits with significant AC ripple at low and high frequencies, supported by specified ripple current ratings at 120 Hz and 100 kHz.

Unique Advantages

• Proven High-Temperature Reliability: 3000-hour endurance at 105°C under rated ripple current provides long-term stability for heat-exposed assemblies.
• Compact Snap-In Form Factor: One-rank smaller case than LGU and a radial snap-in can reduce board footprint without sacrificing capacitance or ripple capability.
• Frequency-Responsive Ripple Ratings: Specified ripple current at both 120 Hz and 100 kHz addresses performance across common ripple spectra.
• Clear Specification Window: Polarized design with ±20% tolerance and explicit leakage/tangent loss characteristics available from the series datasheet simplifies selection and risk assessment.
• RoHS Compliance: Conforms to 2011/65/EU and (EU)2015/863 requirements for restricted substances.
