LGW2D182MELC40

The LGW2D182MELC40 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGW series. It delivers 1.8 mF capacitance at a 200 V rating in a radial, can-style snap‑in package engineered for general-purpose power designs.

Designed for high ripple conditions and elevated operating temperature, this part is specified for continuous operation up to 105°C, withstanding 3,000 hours of rated ripple‑current application at that temperature. The component is RoHS compliant and intended for applications that require robust ripple handling and long thermal endurance.

Key Features

• Capacitance & Voltage — 1.8 mF capacitance rated at 200 V with polarization and a tolerance of −20% to +20%.
• High Ripple Current & Endurance — Specified ripple currents include 4.62 A at 120 Hz and 6.93 A at 50 kHz; rated to withstand 3,000 hours of rated ripple current at 105°C.
• Thermal Performance — Operating temperature range from −40°C to +105°C to support elevated‑temperature applications within the specified rating.
• Package and Mounting — Radial, can-style snap‑in package for secure board mounting; size dimensions L: 4 × D: 3.5 cm and maximum seated height 1.575 inch.
• Leakage and Loss Characteristics — Meets series leakage current specification I ≤ 3√CV (μA) after five minutes at 20°C; series tan δ limits apply per rated voltage.
• Environmental Compliance — Compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power systems — Provides bulk capacitance and high ripple handling for general‑purpose designs that require a 200 V rated capacitor with extended thermal endurance.
• High‑ripple environments — Suited to circuits where sustained ripple current at elevated temperature (up to 105°C) is a design requirement.
• Board‑mounted power modules — Radial snap‑in package facilitates secure mounting in power assemblies that use can‑style electrolytic capacitors.

Unique Advantages

• Proven ripple endurance: Withstands 3,000 hours of rated ripple current at 105°C, supporting designs that demand long‑term stability under continuous ripple stress.
• High ripple capability across frequency: Published ripple current values at both 120 Hz (4.62 A) and 50 kHz (6.93 A) allow design planning for different ripple spectra.
• Wide operating temperature: −40°C to +105°C rating enables use across a broad range of thermal conditions within the part’s specifications.
• Board‑secure mounting: Snap‑in radial can package simplifies installation and mechanical retention on PCBs.
• Regulatory compliance: RoHS conformity supports regulatory and environmental requirements.
• Clear electrical limits: Specified leakage current and tan δ limits (per series datasheet) provide measurable acceptance criteria during qualification and production test.
