LGG2G121MELZ25

The LGG2G121MELZ25 is a snap‑in terminal aluminum electrolytic capacitor rated at 400 V with a nominal capacitance of 120 µF. It is part of Nichicon's LGG series, a 105°C ultra‑smaller‑sized snap‑in family designed for compact equipment applications.

Optimized for general‑purpose use, this radial can capacitor delivers high‑voltage filtering capability in a compact L: 2.5 × D: 2.2 cm package, with RoHS compliance for applications that require lead‑free materials and environmental conformity.

Key Features

• Electrical Performance — 120 µF nominal capacitance at 400 V rated voltage with a tolerance of −20% to +20%. Polarized design for conventional electrolytic capacitor applications.
• Low Loss Characteristics — Maximum tan δ of 0.15 (measured at 120 Hz, 20°C for voltages up to 420 V), supporting stable AC performance in filtering and energy‑storage roles.
• Ripple Handling — Rated ripple current of 680 mA at 120 Hz and 972.4 mA at 100 kHz, enabling effective suppression of AC ripple across a range of frequencies.
• Thermal and Reliability — Operating temperature range of −25°C to +105°C for the 400 V variants, with endurance specified as 2000 hours at 105°C under D.C. bias plus rated ripple current. After endurance testing, capacitance remains within ±20% and leakage current remains at or below initial specified values.
• Mechanical Package — Snap‑in terminal, radial can (snap‑in) package with physical dimensions L: 2.5 × D: 2.2 cm for compact board mounting and secure mechanical retention.
• Leakage Current Specification — Leakage current follows the characteristic I ≤ 3√(C·V) µA (measured after 5 minutes’ application of rated voltage at 20°C), allowing predictable sizing for standby and leakage budgets.
• Low‑Temperature Impedance Stability — For 400 V parts, impedance ratio Z(−25°C)/Z(+20°C) is specified (max) at 8, supporting performance in cooler ambient conditions down to −25°C.
• Marking and Compliance — Marked with white lettering on a black sleeve and compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Electronic Equipment — Suitable where a 400 V, 120 µF polarized capacitor is required for standard power filtering or energy storage in AC/DC or DC/DC systems.
• Compact Power Supplies and Converters — Designed for equipment downsizing goals, offering a smaller‑case snap‑in option from the LGG series for tighter layouts.
• Higher‑Temperature Environments — For designs operating up to 105°C where endurance and stable leakage characteristics over time are required.

Unique Advantages

• Compact Snap‑in Format: Small radial can with snap‑in terminals enables secure board mounting while minimizing occupied volume.
• High‑Voltage Capability: 400 V rating provides margin for high‑voltage filtering and bulk energy storage in power electronics designs.
• Designed for Downsizing: LGG series offers a one‑rank smaller case size than the LGN series, helping reduce overall equipment footprint.
• Predictable Endurance: 2000 hours at 105°C (with defined post‑test limits on capacitance, tan δ and leakage) supports long‑term reliability planning.
• Frequency Versatility: Specified ripple currents at both 120 Hz and 100 kHz provide designers with quantifiable performance across low and high ripple frequencies.
• RoHS Compliant: Meets current RoHS directive requirements for lead‑free assemblies and regulatory conformity.
