Key Features

• Core Electrical — 4.7 mF capacitance at 400 V with ±20% tolerance; polarized design suitable for DC bus and energy-storage uses.
• High Ripple Current — Rated ripple current: 18.8 A at 120 Hz and 26.32 A at 100 kHz, supporting high-frequency and high-current charge/discharge cycles.
• Endurance & Reliability — Load life of 5000 hours at 85 °C under rated ripple and DC bias; endurance criteria include capacitance within ±20%, tan δ within 200% of initial value, and leakage current within initial limits after test.
• Frequency & Loss Characteristics — Specified tan δ (DF) of 0.2 with measurement conditions per datasheet (120 Hz, 20 °C), enabling predictable loss behavior in AC and pulsed applications.
• Thermal Range — Rated for operation from −40 °C to +85 °C, with impedance ratio Z(−40 °C)/Z(+20 °C) = 8 as specified for low-temperature stability.
• Package & Mounting — Radial can with screw terminals for secure electrical and mechanical connection; physical size φ63.5 × 120 mm (L: 12 × D: 6.35 cm) for compact high-energy installations.
• Leakage & Safety — Leakage current specified as not more than 3√V µA or 5 mA (whichever is smaller) after 5 minutes at 20 °C, and withstands AC 2500 V for one minute between terminal and bracket per datasheet.
• Compliance & Packaging — RoHS compliant; supplied in cardboard packing and available in mass production quantities.

Typical Applications

• Industrial Power Supplies — DC bus and bulk energy storage for inverter-fed power supplies where high voltage and sustained ripple are present.
• Inverter Circuits — Energy buffering and smoothing in inverter and high-frequency switching stages, including regenerative circuits for servo drives.
• AC Servomotor Regeneration — Handling high-frequency regenerative voltages in motor drive systems to stabilize DC link voltage during braking and rapid load changes.

Unique Advantages

• High ripple current capability: Rated ripple currents at 120 Hz and 100 kHz support heavy AC and pulsed current loading for inverter and regenerative applications.
• Long rated life: 5000 hours at 85 °C under rated ripple and DC bias provides predictable service life for industrial installations.
• Compact, screw-terminal package: Radial can with screw terminals combines a secure mechanical connection and a compact footprint for high-energy density designs.
• Wide operating temperature range: −40 °C to +85 °C supports deployment across varied industrial environments.
• Controlled loss and leakage behavior: Specified tan δ and leakage current limits provide measurable electrical characteristics for design verification and thermal budgeting.
• Series-level design benefits: LNC series characteristics note smaller size and higher ripple current compared to referenced series, useful when board space and ripple handling are priorities.
