The LGL2W471MELB45 is an aluminum electrolytic, snap‑in terminal capacitor from the Nichicon LGL series, offering 470 µF capacitance at a 450 V rating. It is designed for general‑purpose power applications that require high-voltage bulk capacitance in a compact snap‑in can package.

Key attributes include a −25 to +105 °C operating temperature range, 2000 hours endurance at 105 °C under rated conditions, and tray packing for mass production. The part delivers specified ripple performance across frequency and controlled leakage and loss characteristics per the LGL series datasheet.

Key Features

• Capacitance & Voltage: 470 µF capacitance with a 450 V rated voltage provides high-voltage bulk energy storage for general-purpose designs.
• High-temperature operation: Rated for operation from −25 °C to +105 °C and specified for 2000 hours endurance at 105 °C under D.C. bias plus rated ripple current.
• Endurance and shelf life: Endurance defined as capacitance change within ±20%, tan δ within 200% of initial value, and leakage current not exceeding initial specified value after the 2000 hour test; shelf life treatment specified after 1000 hours at 105 °C.
• Ripple current performance: Rated ripple current of 1.48 A at 120 Hz and 2.116 A at 100 kHz; frequency coefficient data in the LGL series supports ripple handling across frequencies.
• Low-temperature stability and loss: Impedance ratio Z(−25 °C)/Z(+20 °C) specified (max. 8) and tan δ max. of 0.20 at 450 V (measured at 120 Hz, 20 °C), enabling predictable behavior across temperature and frequency.
• Package & mounting: Snap‑in radial can, compact size L: 4.5 × D: 3.0 cm (φ30 × 45 mm), delivered in tray packing for production handling.
• Tolerance & polarity: Capacitance tolerance ±20% (−20% to +20%), polarized device—observe correct polarity in application.
• Leakage current specification: Leakage current defined as I ≤ 3√CV (µA) after 5 minutes application of rated voltage at 20 °C, per datasheet criteria.

Typical Applications

• High-voltage power supplies: Provides bulk capacitance and smoothing for general‑purpose high‑voltage supply circuits requiring 450 V ratings and high-temperature endurance.
• Industrial power electronics: Suited for general-purpose power circuits where compact snap‑in mounting and long endurance at elevated temperatures are required.
• Energy storage and filtering: Used where 470 µF of capacitance at 450 V and controlled ripple handling across frequency are needed for AC/DC or DC/DC stages.

Unique Advantages

• High-voltage bulk capability: 470 µF at 450 V supplies substantial energy storage for designs needing high DC voltage support.
• Designed for elevated temperatures: 105 °C rating and 2000 hours endurance under rated stress reduce risk of premature degradation in hot operating environments.
• Predictable ripple handling: Specified ripple current values at 120 Hz and 100 kHz plus frequency coefficients enable designers to size components against expected ripple spectra.
• Compact, production‑friendly package: Snap‑in radial can with tray packing simplifies assembly and handling for volume manufacturing.
• Measured reliability parameters: Datasheet limits for tan δ, impedance ratio at low temperature, and leakage current provide verifiable electrical behavior for system validation.
