LGZ2W181MELC35

The LGZ2W181MELC35 is an aluminum electrolytic capacitor in a snap-in terminal radial can designed as a long-life member of the LGR/LGZ series. It delivers 180 µF capacitance at a 450 V rating in a compact φ35 × 35 mm package.

Built for general-purpose applications that require sustained performance, the component offers extended endurance at elevated temperatures and compliance with RoHS directives to support environmentally conscious designs.

Key Features

• Electrical Performance — 180 µF rated capacitance with ±20% tolerance (measured at 120 Hz, 20°C), suitable for high-voltage capacitor requirements up to 450 V.
• High-Temperature Endurance — Endurance tested for 20,000 hours at 105°C with DC bias plus rated ripple current; after endurance the capacitance change remains within ±25% and leakage current remains at or below initial specified values.
• Operating Temperature Range — Specified for –25°C to +105°C operation, enabling use across a wide thermal envelope.
• Ripple Current Capability — Rated ripple current of 870 mArms at 105°C, 120 Hz; high-frequency ripple performance specified at 1.244 A at 100 kHz, with frequency coefficients provided for other operating frequencies.
• Leakage and Loss Characteristics — Leakage current defined by I ≤ 3√CV (µA) after 5 minutes at 20°C; tangent of loss angle (tan δ) ≤ 0.20 at 120 Hz, 20°C.
• Package & Mounting — Snap-in terminal, radial can construction in φ35 × 35 mm format for secure board mounting and mechanical stability.
• Environmental Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose — High‑Voltage Circuits — Provides 180 µF at 450 V for designs requiring a high-voltage electrolytic capacitor with long-life assurance.
• General Purpose — Thermal Stress Environments — Rated for continuous operation up to 105°C and endurance of 20,000 hours, suitable where extended elevated-temperature reliability is required.

Unique Advantages

• Long-life assurance: 20,000-hour endurance at 105°C helps extend equipment service intervals and reduces replacement frequency.
• High-voltage capability: 450 V rating supports circuits that require elevated DC voltages with stable capacitance.
• Predictable ripple handling: Rated ripple current of 870 mArms at 120 Hz (105°C) and published frequency coefficients enable accurate thermal and ripple budgeting.
• Robust electrical characteristics: Tight specifications for leakage (I ≤ 3√CV) and tan δ (≤ 0.20) provide predictable behavior after assembly and during operation.
• RoHS compliant: Conformance to RoHS directives supports regulatory and sustainability objectives.
• Secure snap-in mounting: Radial snap-in can simplifies PCB installation while delivering mechanical stability in through-hole assemblies.
