LGN2D102MELA45

The LGN2D102MELA45 from Nichicon is an aluminum electrolytic, snap‑in terminal capacitor designed for general-purpose power applications that require elevated temperature endurance. It belongs to the LGN series and combines a compact snap‑in can package with a rated voltage of 200 V and a capacitance of 1 mF.

Engineered for sustained ripple conditions, this part is specified to withstand continuous rated ripple current operation for 3000 hours at 105°C, making it suitable for demanding thermal and current environments within its rated limits.

Key Features

• Capacitance & Voltage — 1 mF capacitance with a 200 V rated voltage for bulk energy storage and filtering in medium-voltage designs.
• High‑temperature Endurance — Specified to endure 3000 hours of rated ripple-current application at 105°C, supporting long-term operation at elevated temperatures.
• Snap‑in Radial Can Package — Snap‑in terminal mounting in a radial can provides secure board attachment; physical size is L: 4.5 × D: 2.5 cm with a maximum seated height of 1.772 inch.
• Ripple Current Capability — Rated ripple currents of 2.3 A at 120 Hz and 3.45 A at 100 kHz enable handling of continuous AC ripple across common power frequencies.
• Operating Temperature Range — Rated for −40°C to +105°C, matching the series’ specified category temperature range for 160–250 V applications.
• Polarized with Industry Tolerance — Polarized construction with capacitance tolerance of −20% to +20% for predictable electrical behavior in DC applications.
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply bulk filtering — Provides energy storage and smoothing in general‑purpose DC power supplies operating up to 200 V and 105°C.
• DC link / intermediate energy storage — Handles continuous ripple current for intermediate circuits where sustained thermal and ripple performance is required.
• Industrial electronics — Suitable for general-purpose industrial control and power systems that need a compact, snap‑in electrolytic capacitor rated for elevated temperatures.

Unique Advantages

• Proven high‑temperature reliability: Endurance rating of 3000 hours at 105°C under rated ripple current reduces the need for frequent replacements in hot operating environments.
• Compact, space‑efficient footprint: One rank smaller case size than the LGU series while retaining snap‑in mounting, enabling denser board layouts.
• Robust ripple handling: Specified ripple currents at both low and high frequencies (2.3 A @ 120 Hz, 3.45 A @ 100 kHz) allow designers to size components confidently for real-world ripple profiles.
• Wide operating range: −40°C to +105°C operation supports deployment across varied ambient conditions within the rated voltage class.
• Regulatory compliance: RoHS compliance supports environmentally regulated product assemblies.
