LNR2D683MSEN

The LNR2D683MSEN is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNR series, offering 68 mF (68,000 µF) capacitance at a 200 V rating with ±20% tolerance. It is a radial can with screw terminals designed for general-purpose power applications that require high bulk capacitance, substantial ripple handling and extended endurance.

Key value points include high ripple-current capability (22.6 A at 120 Hz, 27.12 A at 100 kHz), a 5000-hour endurance at 85°C, and a polarized screw-terminal package in a φ100 × 250 mm (25 × 10 cm) form factor with standard mounting bracket provisions for larger diameters.

Key Features

• Capacitance & Voltage — 68 mF (68,000 µF) rated at 200 V with ±20% tolerance for bulk energy storage and smoothing.
• Screw-Terminal Construction — Radial can with screw terminals suitable for secure bolted connections; φ100 units use an M8 nominal bolt and are furnished with a standard 3-leg bracket for stable mounting.
• High Ripple-Current Capability — Low-frequency ripple current 22.6 A (120 Hz) and high-frequency ripple current 27.12 A (100 kHz) to support demanding AC and switching environments.
• Leakage & Loss Characteristics — Specified leakage current up to 5000 µA and a tangent of loss angle (tan δ) of 0.25, measured per series specifications at 120 Hz/20°C.
• Thermal Range & Endurance — Rated for operation from −25°C to +85°C (for 160–250 V range); endurance specified as 5000 hours at 85°C with defined post-test limits (capacitance change within ±15%, tan δ ≤175% of initial spec, leakage ≤ initial value).
• Packaging & Compliance — Shipped in cardboard packing; RoHS compliant for environmental conformity.

Typical Applications

• General-purpose power filtering — High capacitance and rated voltage support bulk smoothing and DC link filtering in power supplies and power conversion modules.
• Energy storage for pulsed loads — Large capacitance and high ripple-current ratings help maintain voltage stability during transient or pulsed-load conditions.
• Industrial and commercial equipment — Robust screw-terminal mounting and long endurance at 85°C make this part suitable for stationary equipment needing reliable bulk capacitance.

Unique Advantages

• Substantial bulk capacitance: 68 mF provides significant energy reserve in a single component, reducing the number of parallel capacitors required.
• High ripple-handling: 22.6 A (120 Hz) and 27.12 A (100 kHz) ripple ratings support both low- and high-frequency ripple environments common in switching supplies.
• Long endurance at elevated temperature: 5000 hours at 85°C with defined post-test limits supports predictable aging and maintenance planning.
• Secure mechanical mounting: Screw terminals and a φ100 can with standard 3-leg bracket and M8 bolt nominal diameter provide reliable electrical and mechanical connection for heavy-current applications.
• Measured loss and leakage specs: tan δ of 0.25 and specified leakage current provide clear parameters for design and system-level power budgeting.
• RoHS compliant packaging: Cardboard packing and RoHS conformity simplify environmental compliance and handling.
