LNR1K334MSE

The LNR1K334MSE is a screw‑terminal aluminum electrolytic capacitor designed for general‑purpose bulk energy storage and smoothing in systems that require very high capacitance and substantial ripple handling. It delivers 330,000 µF at 80 V in a robust radial can with screw terminals and is offered in mass production with cardboard packing.

Key value propositions include high capacitance, high ripple current capability at both low and high frequencies, and long endurance at elevated temperature for stable performance in sustained duty applications.

Key Features

• Capacitance & tolerance — 330,000 µF (330 mF) nominal with ±20% tolerance, providing substantial bulk energy storage for DC bus stabilization and smoothing.
• Rated voltage — 80 V rated for applications requiring high voltage DC energy buffering.
• High ripple current capability — 31.8 A at 120 Hz (low frequency) and 36.57 A at 100 kHz (high frequency) to support heavy AC ripple and switching loads.
• Loss characteristics — Tan δ (DF) of 0.4 max at 20°C and 120 Hz for predictable dissipation behavior under operating conditions.
• Leakage current — Specified at 5,000 µA to define standby and initial leakage behavior after voltage application.
• Endurance & temperature range — Rated for 5,000 hours at 85°C; operating temperature range from −40°C to +85°C for long‑term elevated‑temperature reliability.
• Mechanical & mounting — Screw terminal radial can (φ100 × 250L) with robust screw‑mount terminals for secure electrical and mechanical connections in panel or chassis assemblies.
• Environmental compliance — RoHS compliant.

Typical Applications

• General‑purpose power systems — Bulk energy storage and DC bus smoothing where large capacitance and sustained ripple handling are required.
• High‑ripple circuits — Applications that subject capacitors to substantial ripple currents at both low (120 Hz) and high (100 kHz) frequencies benefit from the specified ripple ratings.
• Screw‑terminal assemblies — Equipment and enclosures that require secure screw connections and a radial can package for mounting and serviceability.

Unique Advantages

• Massive bulk capacitance: 330,000 µF provides significant energy reserve to stabilize DC rails and absorb transient loads.
• Dual‑frequency ripple handling: Rated ripple currents at 120 Hz and 100 kHz enable predictable thermal and electrical performance across switching and mains‑frequency domains.
• Long endurance at elevated temperature: 5,000 hours at 85°C supports continuous operation in demanding thermal environments.
• Robust screw‑terminal packaging: Radial can with screw terminals simplifies installation and provides mechanically secure connections for high‑current systems.
• Defined electrical characteristics: Specified tan δ and leakage current values allow engineers to predict dissipation and standby losses during system design.
• Production readiness: Mass production status with cardboard packing supports predictable supply for volume builds.
