LNR1C684MSEN

The LNR1C684MSEN is a screw-terminal aluminum electrolytic capacitor designed for general-purpose power applications that require very large bulk capacitance and robust ripple-current handling. It combines a 680 mF (680,000 µF) capacitance with a 16 V rated voltage in a radial can with screw terminals for secure electrical and mechanical connections.

Key value comes from high ripple-current ratings at both low and high frequencies, a long endurance rating at elevated temperature, and a wide operating temperature range, making it suitable for systems that need substantial energy buffering and sustained performance under continuous load.

Key Features

• Large Capacitance — 680 mF (680,000 µF) for extensive bulk energy storage and smoothing in low-voltage systems.
• 16 V Rated Voltage — Suited for low-voltage DC applications where high capacitance is required.
• High Ripple-Current Capability — 33 A at 120 Hz (low frequency) and 37.95 A at 100 kHz (high frequency) to handle substantial AC ripple under DC bias.
• Long Endurance — Rated for 5000 hours at 85°C with DC bias plus rated ripple current, with defined limits for capacitance change, tan δ, and leakage after endurance testing.
• Wide Operating Temperature — Specified for −40°C to +85°C operation.
• Screw Terminal Mounting — Radial can with screw terminals (φ90 body size with corresponding mounting provisions) for secure, low-resistance connections suitable for heavy-current terminations.
• Leakage Current Specification — Specified leakage current up to 5000 µA (5 mA) as provided in the product data.
• Polarized — Designed for polarized DC applications.
• RoHS Compliant — Meets RoHS environmental compliance as stated in the product data.

Typical Applications

• General-purpose power supplies — Bulk smoothing and energy storage where very large capacitance and high ripple handling are required.
• Power modules and converters — Energy buffering and ripple suppression in general-purpose power conversion assemblies.
• Industrial and commercial equipment — Bulk capacitance for general-purpose systems operating within −40°C to +85°C and requiring screw-terminal connections.

Unique Advantages

• Substantial energy storage: 680 mF capacitance provides significant bulk capacitance in a single component to reduce external component count.
• High ripple tolerance: Dual-frequency ripple ratings (33 A at 120 Hz, 37.95 A at 100 kHz) enable reliable performance under sustained AC ripple conditions.
• Designed for continuous operation: 5000-hour endurance at 85°C under rated conditions supports long-term stability in demanding installations.
• Screw-terminal connectivity: Robust mechanical and electrical termination suited for heavy-current wiring and secure mounting in power assemblies.
• Wide ambient range: −40°C to +85°C operating range accommodates a broad set of environmental conditions for general-purpose deployments.
• Regulatory alignment: RoHS compliance supports use in designs requiring restricted-substance conformity.
