LGN2W101MELZ30

The LGN2W101MELZ30 is a Nichicon LGN series snap‑in aluminum electrolytic capacitor rated 100 µF at 450 V with a 105°C maximum operating temperature. Designed for general‑purpose power applications, this snap‑in can delivers high‑voltage energy storage and smoothing in compact radial can packaging (φ22 × 30 mm).

Key value comes from its high voltage rating, elevated temperature capability and long endurance: rated for 3000 hours at 105°C while maintaining capacitance, dissipation factor and leakage current within specified limits. RoHS compliant and supplied in tray packing for production use.

Key Features

• High Voltage Capability — Rated voltage 450 V for high‑potential DC applications requiring robust bulk capacitance.
• 100 µF Capacitance, ±20% Tolerance — Provides defined bulk energy storage and filtering with industry standard tolerance at 120 Hz, 20°C.
• 105°C Endurance — Designed for extended operation up to 105°C with an endurance of 3000 hours under rated ripple conditions.
• Snap‑in Radial Can Package — φ22 × 30 mm snap‑in terminals for secure chassis or PCB mounting and simplified assembly.
• Ripple Current Performance — Low‑frequency ripple current 690 mA (120 Hz) and high‑frequency ripple current 986.7 mA (100 kHz) to support both mains‑frequency and switching environments.
• Controlled Loss and Leakage — Dissipation factor (tan δ) max 0.20 (measured at 20°C, 120 Hz) and specified leakage current 630 µA for predictable loss and self‑discharge behavior.
• Operating Temperature Range — Rated for −25°C to +105°C, matching high‑temperature industrial operating envelopes for 350–600 V class parts in the LGN series.
• RoHS Compliant — Conforms to applicable RoHS directives for environmental compliance.

Typical Applications

• High‑voltage power supplies — Bulk filtering and smoothing at 450 V where compact, high‑voltage capacitance is required.
• Industrial power conversion — DC link and filtering in converters and inverters that benefit from 105°C endurance and high ripple capability.
• Switching power supplies — Energy storage and ripple suppression for high‑voltage switching stages leveraging both low‑ and high‑frequency ripple ratings.

Unique Advantages

• High‑voltage, compact form factor — 450 V rating combined with a φ22 × 30 mm can balances voltage capability and board/space efficiency.
• Long high‑temperature endurance — 3000 hours at 105°C under rated ripple current supports design longevity in hot operating environments.
• Dual‑frequency ripple specification — Rated ripple currents at 120 Hz and 100 kHz allow predictable thermal and reliability planning across mains and switching domains.
• Predictable electrical behavior — Specified tan δ (0.20) and measured leakage current provide stable loss and self‑discharge characteristics for system design.
• Production‑friendly packaging — Tray packing facilitates handling and assembly in volume manufacturing.
