LGY1K821MELZ25

The LGY1K821MELZ25 is an aluminum electrolytic capacitor in Nichicon's LGY series featuring a snap‑in terminal can and long‑life assurance. It provides 820 µF capacitance at an 80 V rating, designed for general‑purpose use with emphasis on industrial power applications.

With a rated temperature range of −40°C to 105°C and a guaranteed endurance of 5000 hours at 105°C, this part is suited for designers requiring robust, long‑life bulk capacitance in power supplies, ballast circuits and other high‑reliability systems.

Key Features

• Snap‑in terminal construction — Radial, can‑type snap‑in package for secure board mounting and reliable mechanical retention.
• 820 µF capacitance, ±20% tolerance — Bulk energy storage and filtering with industry‑standard capacitance tolerance at 120 Hz, 20°C.
• 80 V rated voltage — Supports higher‑voltage DC applications within the specified rating.
• Long life at elevated temperature — Endurance specified as 5000 hours at 105°C under rated ripple and DC bias.
• High ripple current capability — 1.2 A at 120 Hz (low frequency) and 1.38 A at 100 kHz (high frequency) for effective ripple handling.
• Controlled dissipation factor — tan δ = 0.20 (measured at 20°C, 120 Hz) for predictable loss characteristics.
• Low leakage current — Specified leakage current of 760 µA after standard conditioning.
• Operating temperature range — −40°C to 105°C for broad environmental tolerance.
• Physical size and packaging — Size φ22 × 25 mm (L: 2.5 × D: 2.2 cm); supplied in tray packing; mass production status.
• RoHS compliant — Meets RoHS directive requirements declared for the LGY series.

Typical Applications

• Industrial power supplies — Bulk smoothing and energy storage where long operating life at elevated temperature is required.
• Ballasts — Designed for use in ballast circuits requiring dependable ripple handling and extended endurance.
• General‑purpose power filtering — DC link smoothing and decoupling in higher‑voltage systems up to the 80 V rating.

Unique Advantages

• Extended high‑temperature endurance: 5000 hours at 105°C ensures predictable long‑term performance under continuous stress.
• Robust ripple performance: Specified low‑ and high‑frequency ripple currents (1.2 A at 120 Hz, 1.38 A at 100 kHz) reduce heating and extend service life in real‑world power applications.
• High voltage capability: 80 V rating enables use in higher‑voltage power rails without up‑rating multiple capacitors in series.
• Snap‑in can package: Mechanical stability for PC‑board mounting simplifies assembly for high‑reliability systems.
• Wide temperature range: −40°C to 105°C supports both cold‑start and high‑ambient operating environments.
• Regulatory compliance: RoHS compatibility supports environmental and regulatory requirements for many industrial applications.
