LGR2D331MELA25

The LGR2D331MELA25 from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LGR Long Life series, designed for general-purpose applications requiring robust high-voltage bulk capacitance. It provides 330 µF at a 200 V rating with polarized construction and snap-in radial can packaging for secure board mounting.

Built for continuous operation at elevated temperatures, this part is specified for operation from –40 °C to 105 °C and is rated to withstand ripple current operation for 10,000 hours at 105 °C, offering long-life assurance for demanding power circuits. The device is RoHS compliant.

Key Features

• Core Electricals — 330 µF capacitance at a 200 V rated voltage with ±20% tolerance, providing significant bulk energy storage for high-voltage circuits.
• High-Temperature Long Life — Endurance rated for 10,000 hours at 105 °C under DC bias plus rated ripple current; capacitance change is specified to remain within ±25% after the endurance test.
• Ripple Current Handling — Rated ripple current of 1.2 A at 120 Hz and 1.8 A at 50 kHz, enabling reliable handling of both low- and high-frequency ripple conditions.
• Leakage Current — Specified leakage current follows I ≤ 3√(C·V) µA after 5 minutes at 20 °C, supporting predictable quiescent behavior.
• Dissipation Factor (tan δ) — Measurement at 120 Hz/20 °C shows tan δ ≤ 0.15 for 200 V rated designs, indicating controlled ESR-related losses.
• Package & Mounting — Radial, snap-in can package with snap-in terminals for secure board retention suitable for through-hole PCB assemblies. Physical size: L: 2.5 × D: 2.5 cm.
• Operating Range & Polarization — Polarized capacitor specified for –40 °C to 105 °C operation; designed for polarized DC applications.
• Environmental Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply smoothing — Bulk capacitance for filtering and voltage stabilization in high-voltage power supplies, leveraging the 330 µF/200 V rating and high ripple capability.
• Bulk energy storage — Provides stored energy for hold-up and decoupling in general-purpose power circuits that require long-life performance at elevated temperatures.
• Industrial power rails — Suitable for long-life DC link or rail stabilization where continuous operation at elevated temperature and sustained ripple are required.
• High-frequency ripple environments — Handles higher-frequency ripple (e.g., 50 kHz) with specified ripple current of 1.8 A, useful where switching frequencies produce significant high-frequency components.

Unique Advantages

• Long-life assurance: Endurance rating of 10,000 hours at 105 °C under rated ripple and DC bias provides predictable long-term performance for designs that operate at high temperatures.
• High ripple capability across frequencies: Explicit ripple current ratings at 120 Hz and 50 kHz allow designers to size capacitors confidently for both low- and high-frequency ripple conditions.
• Predictable leakage behavior: Leakage current bounded by I ≤ 3√(C·V) µA after 5 minutes at 20 °C supports power budgeting and safety margin calculations.
• Robust thermal range: –40 °C to 105 °C operating range accommodates a wide span of ambient conditions without derating the core specification set.
• Snap-in mounting for board retention: Radial snap-in package simplifies secure mounting for through-hole assemblies while providing the mechanical stability expected in heavier-currents applications.
• Regulatory compliance: RoHS conformity helps meet environmental requirements for modern electronics assemblies.
