LNT1C683MSE

The LNT1C683MSE is an aluminum electrolytic capacitor in a screw-terminal (radial can) package offering 68,000 µF nominal capacitance at a 16 V rated voltage. It is a high-capacitance, polarized device built for general-purpose power applications that require bulk energy storage and robust ripple handling at elevated temperatures.

Key electrical and mechanical characteristics include a wide operating temperature range of −40°C to +105°C, specified endurance of 2,000 hours at 105°C, and screw-terminal mounting for secure electrical and mechanical connection.

Key Features

• Capacitance and Tolerance — 68,000 µF nominal capacitance with tolerance of −20% to +20%, providing substantial bulk storage for low-voltage power rails.
• Rated Voltage — 16 V DC rated voltage suitable for low-voltage power systems.
• High Ripple Current Capability — Low-frequency ripple current of 7.10 A (120 Hz) and high-frequency ripple current of 8.165 A (100 kHz), enabling effective smoothing under continuous ripple loading.
• Loss and Leakage — Tangent of loss angle (tan δ) specified at 0.6 (20°C, 120 Hz) and leakage current of 3,120 µA, allowing straightforward thermal and DC-bias budgeting.
• Endurance and Temperature — Rated life of 2,000 hours at +105°C and an operating temperature range of −40°C to +105°C for elevated-temperature applications.
• Robust Screw-Terminal Package — Radial can with screw terminals (φ51 × 80 mm) and M5 terminal hardware for secure mounting and power connections.
• Regulatory Status and Packaging — RoHS-compliant and supplied in cardboard packing for handling and storage.

Typical Applications

• Power-supply bulk storage — Large capacitance (68,000 µF) and high ripple-current ratings provide bulk energy storage and smoothing for low-voltage DC power rails.
• DC link and filtering — Screw-terminal mounting and high ripple capability make the part suitable where robust connections and continuous ripple handling are required.
• Industrial and general-purpose electronics — Polarized, high-capacitance solution for general-purpose designs operating across −40°C to +105°C and requiring long-duration endurance at elevated temperature.

Unique Advantages

• Substantial capacitance in a compact can: 68,000 µF in a φ51 × 80 mm package provides significant bulk storage without switching to larger assemblies.
• High continuous ripple handling: Rated for 7.10 A (120 Hz) and 8.165 A (100 kHz), allowing designers to manage ripple-related heating and voltage stability explicitly.
• Designed for elevated-temperature operation: Specified life of 2,000 hours at 105°C supports prolonged use in hotter operating environments.
• Secure screw-terminal connections: M5 screw terminals on a radial can simplify mechanical fastening and high-current terminations compared with leaded options.
• Traceable electrical characteristics: Specified tan δ (0.6 at 20°C, 120 Hz) and defined leakage current (3,120 µA) support accurate modeling in power designs.
• RoHS-compliant packaging: Conforms to RoHS requirements and is shipped in cardboard packing for handling and storage safety.
