LGGW6151MELA25

The LGGW6151MELA25 is a snap-in terminal aluminum electrolytic capacitor in Nichicon’s LGG series. It delivers 150 µF capacitance at a 420 V rating in a compact 25 × 25 mm can, designed for general-purpose high-voltage applications that require reliable bulk capacitance and ripple handling.

Built for environments up to 105°C and supplied in tray packing for mass production, this polarized radial, snap-in capacitor balances a small case size with endurance and ripple performance for industrial and electronic power systems.

Key Features

• Core Electricals: 150 µF capacitance at a 420 V rated voltage with polarization—specified tolerance ±20% at 120 Hz, 20°C.
• Compact Snap‑In Package: Radial, can-type snap-in mounting in a 25 mm diameter × 25 mm length case for secure, board-level installation.
• High‑Temperature Endurance: Rated operating temperature –25°C to +105°C (for 400–450 V range) with endurance of 2000 hours at 105°C under rated DC bias plus rated ripple current.
• Ripple Current Capability: Specified ripple current of 820 mA at 120 Hz and 1.173 A at 100 kHz, supporting AC ripple and filtering duties across frequency ranges.
• Leakage Current Specification: Leakage current meets I ≤ 3√(C·V) (µA) after 5 minutes’ application of rated voltage at 20°C, providing predictable leakage behavior for design calculations.
• RoHS Compliant: Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).
• Identification: Marked with white lettering on a black sleeve for clear part identification.

Typical Applications

• General‑purpose power electronics: Bulk energy storage and smoothing in higher-voltage power supplies and DC link circuits where a 420 V rated capacitor is required.
• Industrial equipment: Filtering and ripple suppression in industrial control systems and power conversion modules operating within the –25°C to +105°C range.
• Mass-production assemblies: Tray-packed snap-in format simplifies board assembly and repeatable mounting for production environments.

Unique Advantages

• High-voltage capability: 420 V rating provides headroom for high-voltage power rails and DC-link applications.
• Compact footprint: One rank smaller case size in the LGG series enables equipment downsizing while retaining required capacitance.
• Designed for elevated temperatures: 2000-hour endurance at 105°C ensures consistent performance in thermally demanding installations.
• Frequency-flexible ripple handling: Specified ripple current at both 120 Hz and 100 kHz supports broad filtering and smoothing requirements.
• Predictable leakage behavior: Leakage current defined by I ≤ 3√(C·V) for straightforward design margins and reliability planning.
• RoHS compliance: Meets current RoHS requirements for environmentally conscious designs.
