LGR2D391MELA30

The LGR2D391MELA30 is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LGR long‑life series. It delivers 390 µF of capacitance at a 200 V rating in a radial, can-style snap‑in package designed for general-purpose applications.

Engineered for elevated ambient operation, this part is specified for continuous use up to 105°C with a long‑life endurance rating of 10,000 hours at 105°C, offering durable bulk capacitance and ripple handling for demanding power circuits.

Key Features

• Capacitance & Voltage — 390 µF rated capacitance with a 200 V working voltage, suitable for circuits requiring substantial bulk capacitance at high DC voltage.
• Long‑life Endurance — Specified lifetime of 10,000 hours at 105°C, meeting the LGR series long life assurance for sustained performance under elevated temperature and ripple stress.
• Wide Operating Temperature — Rated for −40°C to +105°C operation, supporting designs that require broad temperature tolerance.
• Snap‑in Radial Can Package — Snap‑in terminal mounting provides secure PCB retention and straightforward assembly for power supply and chassis installations.
• Ripple Current Capability — Rated ripple current of 1.3 A at 120 Hz and 1.95 A at 50 kHz, enabling effective AC filtering and smoothing in high‑ripple environments.
• Electrical Characteristics — Capacitance tolerance ±20%; polarized construction; leakage current defined by the series specification I ≤ 3√(C·V) µA after 5 minutes at 20°C; tan δ max 0.15 (measurement at 120 Hz, 20°C for 200–400 V).
• RoHS Compliant — Manufactured in compliance with RoHS directives for restricted substances.
• Compact Dimensions — Approximate size L: 3 × D: 2.5 cm with a seated height up to 1.181 inch, useful for space-constrained power modules (see mechanical drawings for exact PCB hole and terminal dimensions).

Typical Applications

• General‑purpose power filtering — Bulk smoothing and decoupling in DC circuits where 200 V rating and high capacitance are required.
• Power supply energy storage — Stabilizing DC rails and absorbing ripple current in power conversion stages operating within the stated temperature and ripple limits.
• Industrial and commercial assemblies — Board‑mounted snap‑in installation for equipment that requires long operating life at elevated temperatures.

Unique Advantages

• Long operational life: 10,000 hours at 105°C reduces maintenance and replacement cycles in continuous‑duty applications.
• High voltage capability: 200 V rating supports higher‑voltage DC rails without series stacking or additional components.
• Robust ripple handling: Specified ripple current at both low and high frequencies supports effective filtering across a range of switching and line conditions.
• Secure snap‑in mounting: Radial snap‑in terminals provide reliable mechanical retention for taller cans in vertical assemblies.
• Clear electrical limits: Leakage current and tan δ specifications give predictable behavior for design verification and end‑of‑life assessments.
• Regulatory compliance: RoHS compliance simplifies use in products requiring restricted‑substance conformity.
