LGL2W471MELC35

The LGL2W471MELC35 from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LGL series designed for general-purpose high-voltage applications. It provides 470 µF capacitance at a 450 V rated voltage in an ultra-smaller-sized, radial snap-in can.

Engineered for elevated operating conditions, the capacitor supports an ambient category temperature range of −25°C to +105°C and is specified for endurance under DC bias plus rated ripple current for 2000 hours at 105°C, making it suitable where compact high-voltage bulk capacitance and reliable thermal performance are required.

Key Features

• Electrical Core — 470 µF capacitance with a 450 V rated voltage and capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• High-temperature Endurance — Endurance tested: 2000 hours at 105°C with DC bias plus rated ripple current. After recovery to 20°C, capacitance remains within ±20% and leakage is at or below the initial specified value.
• Ripple Current Performance — Rated ripple current 1.48 A at 120 Hz and 2.116 A at 50 kHz, with documented frequency coefficients for higher-frequency operation.
• Temperature Stability — Category temperature −25°C to +105°C with a low-temperature impedance ratio Z(−25°C)/Z(+20°C) up to 8 (max), supporting stable performance across the specified range.
• Loss and Leakage Characteristics — Specified tan δ maximum of 0.20 at 450 V (measured at 120 Hz, 20°C) and leakage current defined by I ≤ 3√(C·V) μA after 5 minutes at 20°C.
• Package & Mounting — Radial snap-in can package for secure PCB mounting; compact footprint L: 3.5 × D: 3.5 cm and polarized construction for power circuit use.

Typical Applications

• High-voltage power supplies — Bulk smoothing and energy storage where 450 V rating and elevated ripple capability are needed.
• Industrial power conversion — DC-link and filter applications that require high-voltage capacitance in a compact, snap-in radial package.
• General-purpose high-voltage circuits — Systems requiring reliable, polarized aluminum electrolytic bulk capacitance across −25°C to +105°C.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage designs without stacking multiple capacitors.
• Thermal endurance: Tested for 2000 hours at 105°C under DC bias plus rated ripple current, demonstrating sustained performance in hot environments.
• Measured ripple performance: Defined ripple currents at 120 Hz and 50 kHz (1.48 A and 2.116 A respectively) support designs with both low- and high-frequency ripple content.
• Compact radial snap-in package: Small 3.5 × 3.5 cm footprint in a snap-in can simplifies board layout where space is constrained.
• Predictable electrical characteristics: Clear limits for tan δ, leakage current, and low-temperature impedance ratio enable engineering trade-offs and reliable BOM planning.

Why Choose LGL2W471MELC35?
