LGN2H221MELC35

The LGN2H221MELC35 is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose high‑voltage applications. This smaller‑sized member of Nichicon’s LGN series pairs a 220 µF capacitance with a 500 V rating and a snap‑in radial can package for robust board mounting.

Engineered for durability in elevated temperatures, the part withstands rated ripple current for 3000 hours at 105°C and is RoHS‑compliant, making it suitable for designs that require sustained performance under thermal stress.

Key Features

• Capacitance & Voltage — 220 µF capacitance at a 500 V rated voltage for high‑voltage energy storage in general‑purpose circuits.
• High‑Temperature Endurance — Specified endurance of 3000 hours at 105°C under D.C. bias plus rated ripple current, with post‑test limits: capacitance change within ±20%, tan δ ≤ 200% of initial, and leakage current ≤ initial specified value.
• Snap‑In Radial Can Package — Snap‑in terminals and compact case (L: 3.5 × D: 3.5 cm) for secure mounting and reduced board footprint; one rank smaller case than LGU series.
• Ripple Current Capability — Rated ripple current of 1.02 A at 120 Hz and 1.459 A at 100 kHz to handle AC ripple across a range of frequencies.
• Operating Temperature Range — Specified for −25°C to +105°C operation for use in elevated temperature environments.
• Electrical Characteristics — Capacitance tolerance −20% to +20%; leakage current per series specification (I ≤ 3√(µA) after 5 minutes’ application of rated voltage at 20°C); tan δ max 0.20 for 450–600 V at 120 Hz, 20°C.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose High‑Voltage Circuits — Suited to designs that call for a 500 V, 220 µF capacitor in a snap‑in radial can form factor for energy storage and smoothing in general applications.
• Power Electronics and Supplies — The combination of voltage rating, capacitance and ripple handling supports use where sustained ripple current and elevated operating temperatures are expected.
• Industrial Equipment — Small‑footprint, high‑voltage capability and long high‑temperature endurance make it applicable to industrial power modules and assemblies requiring reliable electrolytic capacitance.

Unique Advantages

• Long High‑Temperature Life: 3000 hours endurance at 105°C under rated ripple current delivers predictable aging and characteristic retention in hot environments.
• Compact Snap‑In Packaging: Snap‑in radial can with one rank smaller case than LGU saves board space while providing robust mechanical retention.
• High Voltage and Capacitance Combination: 500 V rating with 220 µF capacitance addresses high‑voltage energy storage needs without upsizing the case.
• Measured Ripple Performance: Specified ripple current values at 120 Hz and 100 kHz enable designers to match capacitor selection to expected ripple spectra.
• RoHS Compliance: Meets current RoHS directive requirements for environmentally restricted substances.
• Series Electrical Specs: Defined leakage current and tan δ limits provide clear acceptance criteria for quality control and design verification.
