LGY2A102MELA30

The LGY2A102MELA30 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGY series, engineered for long‑life industrial power applications. It provides 1000 µF capacitance at a 100 V rating in a compact φ25 × 30 mm can, delivering high ripple tolerance and stable performance across –40 °C to 105 °C.

Designed for systems that require dependable bulk energy storage and smoothing under sustained thermal and ripple stress, this part offers 5000 hours of endurance at 105 °C and RoHS compliance for regulated manufacturing environments.

Key Features

• Long‑life assurance — Endurance specified at 5000 hours when DC bias plus rated ripple current is applied at 105 °C, supporting reliable operation in continuous‑duty power systems.
• Snap‑in terminal package — Radial, can‑snap‑in mounting for secure mechanical and electrical connection in power supply assemblies and industrial equipment.
• High voltage rating — 100 V rated voltage suitable for higher DC bus and power‑stage applications requiring elevated voltage capability.
• Low loss (tan δ) — tan δ specified at 0.20 (measurement condition: 20 °C, 120 Hz), indicating controlled dissipation for reduced heating under AC ripple.
• High ripple handling — Rated low‑frequency ripple current of 1.5 A at 120 Hz and high‑frequency ripple current of 1.725 A at 50 kHz to support demanding filtering and smoothing tasks.
• Controlled leakage — Leakage current specified at 940 µA, within the datasheet’s limits for stable performance after voltage application.
• Operating temperature range — –40 °C to 105 °C for use in a wide range of industrial temperature environments.
• Compact footprint — Size φ25 × 30 mm (L: 3 cm × D: 2.5 cm), enabling space‑efficient placement in power modules and control cabinets.
• Regulatory — RoHS compliant for environmental and regulatory conformity.

Typical Applications

• Industrial power supplies — Bulk energy storage and output filtering where sustained high temperature and ripple endurance are required.
• Ballasts and lighting control — AC/DC smoothing and ripple suppression in ballast circuits, leveraging the part’s long‑life rating at 105 °C.
• Motor drives and converters — DC link and smoothing capacitors in drive electronics benefitting from the 100 V rating and high ripple capability.

Unique Advantages

• Validated 5000‑hour endurance at 105 °C: Ensures predictable lifetime performance in continuous high‑temperature applications.
• High ripple capability across frequencies: Specified ripple currents at 120 Hz and 50 kHz let designers size capacitors for both line‑frequency and high‑frequency switching environments.
• Low dissipation factor: tan δ = 0.20 (120 Hz, 20 °C) reduces self‑heating and improves thermal stability under AC stress.
• Snap‑in mechanical reliability: Robust termination style simplifies board assembly and provides secure mounting in power assemblies.
• Compact, high‑voltage form factor: 1000 µF at 100 V in a φ25 × 30 mm can saves PCB and enclosure space while supporting higher DC bus voltages.
• RoHS compliance: Meets environmental requirements for regulated product lines.
