LNR1J474MSEN

The LNR1J474MSEN is an aluminum electrolytic capacitor in a screw‑terminal, radial can package designed for general‑purpose power applications. It delivers very high bulk capacitance (470000 µF) at a 63 V rated voltage with robust screw terminals for secure electrical and mechanical connection.

Engineered for applications that require large energy storage and sustained ripple handling, this part combines high ripple current capability, a wide operating temperature range (‑40°C to 85°C) and a 5000 hour endurance at 85°C to support reliable operation in demanding power systems.

Key Features

• Capacitance & Voltage: 470000 µF (470 mF) rated at 63 V, providing substantial bulk energy storage for smoothing and reservoir applications.
• Tolerance: ±20% capacitance tolerance at 120 Hz, 20°C, enabling predictable performance in design margins.
• High Ripple Current Handling: 33.6 A at 120 Hz (low frequency) and 38.64 A at 100 kHz (high frequency), reducing heating and preserving lifetime under heavy ripple conditions.
• Leakage Current: Specified leakage current of 5000 µA; series guidance defines leakage after 5 minutes as not more than 3√CV (µA) or 5 mA, whichever is smaller.
• Endurance & Reliability: Rated for 5000 hours at 85°C with specified post‑test limits: capacitance change within ±15%, tan δ within 175% of initial specified value, and leakage current not exceeding the initial specification.
• Temperature Range: Operates from ‑40°C to +85°C, supporting a broad set of ambient environments.
• Package & Mounting: Radial can with screw terminals and standard mounting brackets for φ100 body (φ100 × 250L dimension), packed in cardboard and offered in mass production.
• Tan δ (dissipation factor): 0.6 (measurement reference available in series datasheet at 120 Hz, 20°C).
• RoHS Compliance: Product is RoHS compliant.

Typical Applications

• General-purpose power systems: Large bulk capacitance and high rated voltage make this part suitable where substantial energy storage and smoothing are required in general‑purpose power electronics.
• High-ripple environments: High low‑ and high‑frequency ripple current ratings support use in circuits exposed to significant AC ripple currents.
• Industrial power modules: Robust screw‑terminal mounting and large physical size support secure installation in industrial power assemblies and serviceable modules.

Unique Advantages

• Very high bulk capacitance: 470000 µF provides large energy reservoir capacity to stabilize DC rails and absorb transient events.
• Strong ripple tolerance: 33.6 A (120 Hz) and 38.64 A (100 kHz) ratings reduce operating temperature rise and extend service life under ripple stress.
• Long endurance at elevated temperature: 5000 hours at 85°C with specified post‑test limits ensures predictable long‑term behavior in continuous operation.
• Secure screw‑terminal connections: Designed for robust electrical and mechanical connection in assemblies that require reliable serviceability and high current handling.
• Wide ambient capability: ‑40°C to +85°C operating range covers a broad set of deployment conditions.
• Regulatory compliance: RoHS compliance supports environmentally constrained designs.
