LGX2D152MELB50

The LGX2D152MELB50 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGX series designed for long‑life, high‑temperature power applications. It delivers 1.5 mF capacitance at a 200 V rating in a compact radial can with snap‑in mounting.

Engineered for rectifier stages and general power electronics, this part offers a 105°C operating range and a 5000‑hour long‑life assurance under rated ripple conditions, making it suitable for inverter and switching power supply designs that require sustained ripple handling and thermal endurance.

Key Features

• Form factor & termination — Snap‑in terminal, radial can package for secure board mounting and easy mechanical retention.
• Capacitance & voltage — 1.5 mF (1500 µF) nominal capacitance with a 200 V rated voltage and ±20% tolerance.
• High operating temperature & long life — Rated for −25°C to +105°C and specified for 5000 hours under rated ripple current at 105°C.
• Ripple current capability — Rated ripple current of 3 A at 120 Hz (low frequency) and 4.5 A at 50 kHz (high frequency) to support rectifier and switching stages.
• Reliability metrics — Endurance: after 5000 hours at 105°C with DC bias plus rated ripple, capacitance change within ±20%, tan δ ≤ 200% of initial spec, and leakage current at or below initial specified value.
• Leakage current specification — Leakage current defined as I ≤ 3√(C·V) µA after 5 minutes at 20°C (C in µF, V in V).
• Size — Compact dimensions (L: 5 × D: 3 cm) to support space‑constrained power designs.
• Environmental compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Polarized design — Intended for DC smoothing and bulk energy storage in polarized circuits.

Typical Applications

• Rectifier circuits for inverters — Bulk filtering and smoothing in inverter rectifier stages where high ripple currents and elevated operating temperature are present.
• Switching power supplies — DC link and output smoothing in switching PSUs requiring sustained ripple handling and long‑term stability at up to 105°C.
• General-purpose power electronics — Applications that need polarized bulk capacitance with snap‑in mounting and RoHS compliance for reliable, compact power designs.

Unique Advantages

• Proven long‑life performance: Rated for 5000 hours at 105°C under rated ripple, providing predictable endurance in high‑temperature operating environments.
• Dual-frequency ripple capability: Rated ripple currents of 3 A at 120 Hz and 4.5 A at 50 kHz, enabling use across rectifier and switching frequency domains.
• Compact, secure mounting: Snap‑in radial can design simplifies assembly and provides robust mechanical retention on the PCB.
• Measurable electrical stability: Endurance limits ensure capacitance remains within ±20% and leakage does not increase beyond initial specifications after life testing.
• Clear leakage specification: Leakage current governed by I ≤ 3√(C·V) µA after initial application of rated voltage, supporting predictable design calculations.
• Regulatory compliance: RoHS conformity supports designs targeting restricted‑substance compliance requirements.
