LGW2E821MELC30

The LGW2E821MELC30 is an aluminum electrolytic capacitor from Nichicon's LGW series featuring a snap-in terminal radial can design. It delivers 820 µF at a 250 V rating with polarized construction and is intended for general-purpose applications that require high ripple current handling and extended endurance at elevated temperatures.

Designed for continuous operation up to 105°C, this part provides a combination of capacitance, voltage capability and ripple tolerance suitable for demanding power environments and industrial electronics where long-term stability is required.

Key Features

• Capacitance & Voltage: 820 µF rated capacitance at 250 V to support bulk energy storage and decoupling in power systems.
• High ripple current handling: Rated ripple currents include 3 A at 120 Hz and 4.5 A at 50 kHz; frequency coefficients in the LGW series increase allowable ripple at higher frequencies (up to 1.50 for 200–250 V at 50 kHz or more).
• 105°C endurance: Endurance proven to withstand 3000 hours of rated ripple current application at 105°C, with defined limits for capacitance change, tan δ and leakage current after test.
• Operating temperature range: –40°C to +105°C for the 200–250 V range, suitable for elevated-temperature environments.
• Leakage current specification: I ≤ 3√CV (µA) after 5 minutes' application of rated voltage at 20°C, per the LGW series specification.
• Tangent of loss angle (tan δ): Maximum tan δ of 0.15 (measured at 120 Hz, 20°C) for the 200–400 V range.
• Mechanical/package: Snap-in terminal, radial can package; size L: 3 × D: 3.5 cm for compact board mounting.
• Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).
• Capacitance tolerance: ±20% at 120 Hz, 20°C.

Typical Applications

• General-purpose power circuitry: Bulk capacitance and high ripple capability make this capacitor suitable for general-purpose power applications requiring energy storage and filtering.
• Industrial equipment: Extended 105°C endurance and high ripple rating support prolonged operation in industrial power subsystems.
• High-frequency power modules: Frequency-dependent ripple coefficients allow this part to support higher allowable ripple at elevated switching frequencies in power electronics.

Unique Advantages

• Proven high-ripple endurance: Specified to withstand 3000 hours at rated ripple and 105°C, providing predictable long-term behavior under continuous ripple stress.
• Frequency-adaptive ripple capability: Ripple current allowance increases with frequency (per series frequency coefficients), supporting modern switching environments.
• Compact snap-in package: Radial, snap-in can simplifies secure PCB mounting while offering substantial capacitance in a compact footprint (L: 3 × D: 3.5 cm).
• Controlled leakage and dissipation: Leakage current limited by I ≤ 3√CV and tan δ specified for the voltage range, enabling reliable performance characterization.
• Regulatory compliance: RoHS compliant for use in systems requiring restricted-substance conformity.
