LNT1H683MSE

The LNT1H683MSE is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNT series. It provides high bulk capacitance (68,000 µF) at a 50 V rated voltage in a radial can with screw terminals for secure electrical and mechanical connection.

Designed for general-purpose applications, this capacitor delivers high ripple-current capability and a wide operating temperature range, making it suitable where large capacitance and robust terminal mounting are required.

Key Features

• Capacitance & Tolerance — 68,000 µF (68 mF) with a capacitance tolerance of -20% to +20% at 120 Hz, 20°C.
• Rated Voltage — 50 V DC rated voltage for mid-voltage power applications.
• High Ripple Current — Low-frequency ripple current 12.8 A (120 Hz) and high-frequency ripple current 14.72 A (100 kHz), enabling effective smoothing under high AC ripple conditions.
• Endurance — Rated for 2000 hours at +105°C under specified conditions, supporting sustained operation at elevated temperatures.
• Temperature Range — Operates from -40°C to +105°C to support demanding thermal environments.
• Loss Tangent (tan δ) — tan δ = 0.35 measured at 20°C, 120 Hz, for predictable dissipation characteristics.
• Leakage Current — Specified leakage current: 5000 µA.
• Package & Mounting — Radial can with screw terminals (φ63.5 × 120L) for robust, serviceable connections; packaged in cardboard for shipment.
• Compliance & Availability — RoHS compliant and available in mass-production status.

Typical Applications

• General Purpose — For designs requiring large bulk capacitance and secure screw-terminal mounting in general-purpose power and electronic equipment.
• High-Temperature Environments — Suitable where operation up to +105°C is required, supported by a 2000-hour endurance rating at that temperature.
• High-Ripple Circuits — Applicable where significant ripple-current handling is needed, given the specified low- and high-frequency ripple current ratings.

Unique Advantages

• Very high capacitance — 68,000 µF provides substantial bulk energy storage for smoothing and decoupling in compact form factors.
• Robust ripple handling — 12.8 A (120 Hz) and 14.72 A (100 kHz) ripple-current ratings help reduce voltage ripple under heavy AC loading.
• Secure screw-terminal connections — Screw terminals enable reliable, serviceable electrical and mechanical connections for heavier current paths.
• Wide operating temperature — -40°C to +105°C range and a 2000-hour life rating at 105°C for dependable performance in elevated-temperature applications.
• Predictable dissipation and leakage — Specified tan δ (0.35 at 20°C/120 Hz) and leakage current (5000 µA) allow engineering trade-offs to be made from measured parameters.
• RoHS compliant and production-ready — Conforms to RoHS requirements and is available in mass-production quantities with cardboard packing.
