• 50 V Rated Voltage — Rated voltage of 50 V suitable for medium‑voltage power rails and general‑purpose power designs.
• Snap‑In Mounting — Snap‑in terminal (radial, can – snap‑in) package for secure board retention and efficient assembly.
• Validated Endurance — Life/Endurance of 3,000 hours at 105°C with specified DC bias plus rated ripple current applied, meeting LGU series endurance criteria.
• Wide Operating Temperature — −40°C to 105°C operating range for use across varied thermal environments.
• High Ripple Current Capability — Low‑frequency ripple current 4.77 A (120 Hz) and high‑frequency ripple current 5.486 A (50 kHz) to handle real‑world AC ripple conditions.
• Leakage and Loss Characteristics — Specified leakage current of 2,590 µA and tan δ (DF) max 0.30 (measured at 20°C, 120 Hz) to support predictable performance.
• Compact Mechanical Profile — Size φ35 × 50 mm (L: 5 × D: 3.5 cm) and tray packing for straightforward handling in production.
• Regulatory — RoHS‑compliant construction.

Typical Applications

• General Purpose Electronics — Bulk energy storage and smoothing for a variety of general‑purpose electronic equipment where a high‑capacitance, 50 V snap‑in solution is needed.
• Power Supplies — Filtering and reservoir capacitance on DC bus rails, leveraging high ripple current ratings and 15,000 µF capacitance.
• Industrial Equipment — Stabilization of power rails and decoupling in industrial systems within the −40°C to 105°C temperature range.
