LGM2W471MELC30

The LGM2W471MELC30 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGM series, designed for general‑purpose use in equipment where high voltage and compact size are required. Its ultra‑smaller‑sized case (one rank smaller than LGL) supports equipment down‑sizing while delivering a 470 µF, 450 V capacitance solution with polarized snap‑in mounting.

Engineered for elevated operating temperatures and sustained ripple handling, this part is suitable where durable high‑voltage bulk capacitance and compact packaging are priorities.

Key Features

• Capacitance & Voltage — 470 µF rated capacitance at 450 V provides high‑voltage bulk energy storage for power applications requiring substantial charge capacity.
• Compact Snap‑in Package — Radial can with snap‑in terminals for reliable PCB mounting; one rank smaller case than LGL to aid equipment downsizing.
• High Temperature Endurance — Rated for operation from –25°C to +105°C with an endurance specification of 2000 hours at 105°C when DC bias plus rated ripple current is applied.
• Ripple Current Performance — Rated ripple current of approximately 1.00 A at 120 Hz (1000 mArms) and frequency performance supporting up to 1.43 A at higher frequencies (50 kHz coefficient), enabling effective ripple handling across a range of operating frequencies.
• Electrical Loss and Leakage — Tangent of loss angle (tan δ) ≤ 0.20 at 120 Hz, 20°C; leakage current specified as I ≤ 3√(C·V) µA after 5 minutes at 20°C, providing predictable DC characteristics.
• RoHS Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863), supporting environmental and regulatory requirements.
• Polarized Device — Designed as a polarized electrolytic capacitor for DC applications requiring correct polarity handling.
• Physical Dimensions — Compact dimensions corresponding to a 35 × 30 mm case (nominally L: 3.0 cm × D: 3.5 cm) suitable for space‑constrained assemblies.

Typical Applications

• High‑voltage power supplies — Bulk energy storage and smoothing where a 450 V rating and 470 µF capacitance are required for stable DC rails.
• Equipment downsizing — Replacement or redesign scenarios demanding smaller case sizes without sacrificing capacitance or voltage capability.
• General‑purpose industrial electronics — Applications that need reliable polarized high‑voltage capacitors with elevated temperature endurance.

Unique Advantages

• Space‑efficient high voltage solution: One rank smaller case than LGL lets designers maintain capacitance and voltage while reducing PCB footprint.
• High temperature reliability: 2000‑hour endurance at 105°C under rated conditions supports long‑term performance in hot operating environments.
• Predictable ripple handling: Specified ripple current values and frequency coefficients enable tighter design margins for ripple and thermal management.
• Measurable electrical stability: Defined tan δ and leakage current limits provide verifiable electrical behavior for system modeling and validation.
• Assembly‑friendly termination: Snap‑in radial can simplifies mechanical retention and PCB insertion for manufacturability.
• Regulatory compliance: RoHS conformity helps meet environmental requirements for commercial and industrial equipment.
