LNR1H683MSE

The LNR1H683MSE is a screw-terminal aluminum electrolytic capacitor designed for general-purpose applications that require very high capacitance in a radial can package. It delivers 68,000 µF at a rated 50 V with screw terminals and a φ51 mm × 100 mm body, offering a compact, serviceable solution for equipment that needs bulk capacitance and robust electrical connections.

Built for sustained operation up to 85°C with a rated endurance of 5,000 hours at that temperature, this capacitor balances large stored charge capability with ripple-current handling suitable for demanding general-purpose designs.

Key Features

• Capacitance & Voltage — 68,000 µF rated capacitance at 50 V, specified with ±20% tolerance at 120 Hz, 20°C.
• Screw Terminal Mounting — Radial can with screw terminals for secure bolted connections; body diameter φ51 mm and length 100 mm.
• High Ripple Current — Rated ripple current of 11 A at 120 Hz and 12.65 A at 100 kHz for applications with significant AC stress.
• Endurance at Elevated Temperature — Rated for 5,000 hours at 85°C with post-endurance capacitance change within ±15% and leakage current maintained at or below initial specified value.
• Wide Operating Temperature — Specified operating range from –40°C to +85°C.
• Leakage Current Specification — After 5 minutes’ application of rated voltage (at 20°C), leakage current is not more than 3√CV (µA) or 5 mA, whichever is smaller.
• Polarized, Radial Can Package — Polarized aluminum electrolytic in a screw-terminal radial can; standard supply includes 3-leg bracket for φ51 mm and larger bodies.
• RoHS Compliant — Conforms to RoHS requirements for environmental compliance.

Typical Applications

• General-purpose equipment — Intended for general-purpose use where large capacitance and screw-terminal mounting are required.
• Rugged installed assemblies — Screw terminals and standard 3-leg bracket attachment for φ51 mm bodies support secure mechanical mounting and bolted electrical connections.
• High-stress AC environments — Suitable where notable ripple currents occur, supported by specified ripple ratings at 120 Hz and 100 kHz.

Unique Advantages

• Substantial stored charge: 68,000 µF at 50 V provides large capacitance capacity for designs that require significant energy buffering.
• Engineered for long-term elevated-temperature use: 5,000-hour endurance at 85°C with tight post-endurance limits on capacitance and leakage current supports predictable life performance.
• High ripple-current capability: Rated ripple current of 11 A (120 Hz) and 12.65 A (100 kHz) helps manage AC stress in demanding circuits.
• Robust mechanical and electrical connections: Screw-terminal design with standard bracket mounting (3-leg for φ51 mm bodies) enables secure, serviceable installation.
• Clear leakage specification: Leakage current guaranteed to be ≤ 3√CV (µA) or 5 mA after 5 minutes at 20°C, enabling predictable leakage behavior for design verification.
• Environmentally compliant: RoHS compliance supports use in regulated supply chains.
