LGA2W151MELA25

The LGA2W151MELA25 is a Nichicon LGA series aluminum electrolytic capacitor in a snap‑in radial can package. It delivers high capacitance and high ripple‑current capability in a compact 25 × 25 mm footprint for general‑purpose applications.

Designed for long life under elevated temperature and ripple stress, this part withstands rated ripple current for 5000 hours at 105°C and is RoHS compliant.

Key Features

• Electrical — 150 µF capacitance at 450 V rated voltage with ±20% tolerance (120 Hz, 20°C).
• High ripple capability — Rated ripple current 1.1 A at 120 Hz; frequency performance supports higher ripple at higher frequencies (example: ~1.573 A at 50 kHz).
• High‑temperature endurance — Endurance verified for 5000 hours with D.C. bias plus rated ripple current at 105°C; after test, capacitance remains within ±20% of initial value.
• Package & mounting — Snap‑in radial can (φ25 × 25 mm) for secure board retention and easy assembly.
• Leakage and dissipation — Low leakage current (≈0.77 mA after 5 minutes at 20°C for this part) and tan δ ≤ 0.20 (120 Hz, 20°C).
• Wide operating range — Rated for operation from −40°C to +105°C.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose assemblies — Bulk capacitance and energy storage where a high‑voltage, high‑capacitance electrolytic is required.
• High‑ripple circuits — Circuits that require sustained ripple current handling at elevated temperature up to 105°C.
• Long‑life installations — Designs that need components specified for extended endurance under DC bias and ripple stress.

Unique Advantages

• Proven long‑term endurance: Specified to withstand rated ripple current for 5000 hours at 105°C, supporting reliability in sustained high‑temperature operation.
• High voltage and capacitance in a compact can: 150 µF at 450 V in a 25 × 25 mm footprint minimizes board area for high‑voltage bulk capacitance.
• Robust ripple performance: Rated ripple current of 1.1 A at 120 Hz and higher-frequency capability reduce thermal stress in demanding ripple environments.
• Secure, production‑friendly mounting: Snap‑in radial package simplifies PCB assembly and mechanical retention compared with loose can styles.
• Quantified electrical limits: Clear leakage, tan δ, and impedance specifications enable predictable design margining and validation.
• Regulatory compliance: RoHS conformity supports use in regulated product lines.
