Key Features

• Core Electrical: 33,000 µF capacitance at 63 V with ±20% tolerance, providing large bulk energy storage for smoothing and decoupling in general‑purpose power circuits.
• Loss Characteristics: tan δ = 0.25 (measured at 20 °C, 120 Hz), enabling predictable dissipation characteristics for thermal and ripple design.
• High Ripple Current Capability: Rated low‑frequency ripple current of 8.8 A at 120 Hz and high‑frequency ripple current of 10.12 A at 100 kHz to support high‑duty power environments.
• Leakage Current: Specified leakage current of 4,320 µA, allowing engineers to account for standby and steady‑state losses in power budgets.
• Reliability & Endurance: Endurance rating of 5,000 hours at 85 °C under rated voltage and ripple conditions, with specified limits for capacitance change, tan δ and leakage after the endurance test.
• Mechanical & Mounting: Screw‑terminal radial can (φ51 × 80 mm) designed for secure, high‑current connections; nominal terminal bolt size for φ51 body is M5 per the LNR series specification.
• Compliance & Packaging: RoHS‑compliant and supplied in cardboard packing; product is in mass production.

Typical Applications

• General‑purpose power filtering: Bulk energy storage and smoothing in power supplies and industrial electronics where high capacitance and ripple handling are required.
• Power conversion systems: DC bus and energy buffering in converters and inverters that benefit from screw‑terminal connections for high‑current wiring.
• Industrial equipment: Long‑life installations operating across −40 °C to 85 °C that require predictable endurance and leakage characteristics.

Unique Advantages

• Large bulk capacitance: 33,000 µF provides substantial energy storage for smoothing and transient support, reducing the need for parallel capacitor arrays.
