LGC2H121MELZ35

The LGC2H121MELZ35 from Nichicon is an aluminum electrolytic, snap‑in terminal capacitor delivering 120 µF at a 500 V rating. It belongs to the LGC series designed for long life and ultra‑small sizing—one rank smaller than the LGX series—making it suitable for equipment down‑sizing where high voltage capacitance and reliable long‑term operation are required.

Engineered for general‑purpose use, this polarized capacitor supports an operating range of –40°C to +105°C and is RoHS‑compliant.

Key Features

• High Voltage / Capacitance — 120 µF rated at 500 V for applications that require substantial DC energy storage at elevated voltages.
• Snap‑In Terminal Package — Radial, can‑snap‑in mounting for secure board attachment and straightforward assembly.
• Compact, Space‑Saving Case — Ultra‑smaller‑sized design (one rank smaller than LGX) with dimensions approximately 22 × 35 mm (L × D), enabling equipment downsizing.
• High Temperature, Long Life — Rated for –40°C to +105°C with an endurance specification of 5000 hours at 105°C under D.C. bias plus rated ripple current.
• Ripple Current Capability — Rated ripple current of 960 mA at 120 Hz and 1.373 A at 50 kHz to support filtering and smoothing under AC ripple conditions.
• Leakage and Loss Characteristics — Leakage current defined as I ≤ 3√(CV) µA (after 5 minutes at 20°C); tangent of loss angle (tan δ) ≤ 0.25 at 120 Hz, 20°C.
• Low‑Temperature Stability — Impedance ratio Z(–25°C)/Z(+20°C) ≤ 8 (120 Hz) for maintained performance in colder environments.
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Power Circuits — Provides bulk capacitance and ripple smoothing where a 500 V, 120 µF polarized capacitor is required.
• Equipment Downsizing — Ultra‑smaller case footprint (one rank smaller than LGX) helps shrink power module and system layouts without sacrificing rated capacitance.
• High‑Temperature Environments — Rated to +105°C with 5000 hours endurance, suitable for designs that operate or are stored at elevated temperatures.

Unique Advantages

• High Voltage Handling: 500 V rating supports higher‑voltage DC link and filtering duties without additional series stacking.
• Long Operational Life: Endurance specified at 5000 hours at 105°C under D.C. bias plus rated ripple current, providing predictable long‑term performance.
• Space Efficiency: One rank smaller case than LGX offers a direct size advantage for designers focused on compacting assemblies.
• Robust Ripple Performance: Defined ripple current ratings (960 mA at 120 Hz; 1.373 A at 50 kHz) and frequency coefficients in the datasheet allow accurate thermal and ripple budgeting.
• Predictable Leakage and Loss: Leakage current and tan δ limits enable engineers to estimate standby and power losses for system-level design.
• RoHS Compliance: Conforms to current RoHS directives for ease of regulatory compliance in global product deployments.
