LGW2W471MELC45

The LGW2W471MELC45 is a snap‑in terminal type aluminum electrolytic capacitor rated at 470 µF and 450 V with a 105°C temperature rating. Designed for general‑purpose high‑voltage applications, it offers high ripple current capability and long endurance under rated ripple current conditions.

Key Features

• Electrical Rating — 470 µF capacitance with ±20% tolerance and 450 V rated voltage for high‑voltage DC applications.
• High Temperature & Endurance — Rated for operation to 105°C and guaranteed to withstand 3000 hours of rated ripple current at 105°C when tested per the datasheet endurance conditions.
• High Ripple Current — Specified ripple current of 2.67 A at 120 Hz and 3.818 A at 50 kHz; frequency coefficients for the 400–450 V group are provided (e.g., 0.77 at 50 Hz, 1.00 at 120 Hz, 1.43 at ≥50 kHz).
• Reliability Metrics — Leakage current limit defined as I ≤ 3√CV (µA) after 5 minutes at 20°C; tan δ limit at 450 V is 0.20 measured at 120 Hz and 20°C.
• Package & Mounting — Radial can, snap‑in terminal package for secure PCB mounting.
• Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose high‑voltage power circuits — Provides bulk capacitance and high ripple current endurance where 450 V rated capacitors are required.
• Systems requiring high‑temperature endurance — Suitable for designs that operate up to 105°C and need long ripple current life.
• Snap‑in PCB assemblies — Intended for radial, snap‑in mounting in assemblies that prefer can‑type electrolytic capacitors for ease of installation.

Unique Advantages

• High ripple‑current endurance: Withstands 3000 hours of rated ripple current at 105°C, enabling longer service life under continuous AC loading.
• High‑voltage capability: 450 V rating supports higher DC bus and power supply voltages without requiring series stacks.
• Clear reliability limits: Endurance and shelf‑life criteria (capacitance change, tan δ, leakage) are specified in the datasheet for predictable performance over time.
• Frequency performance data: Published frequency coefficients and ripple current values for 120 Hz and high frequencies (up to 50 kHz) simplify thermal and ripple‑current derating in design calculations.
• RoHS compliant: Meets applicable RoHS requirements for material compliance.
