LNR1J683MSE

The LNR1J683MSE is an aluminum electrolytic capacitor in Nichicon’s LNR series, featuring a screw terminal radial can package and a large 68 mF (68,000 µF) capacitance at 63 V. It is designed for general-purpose applications that require bulk capacitance, robust ripple handling and secure screw-terminal mounting.

With an operating range from –40°C to 85°C and a rated lifetime of 5,000 hours at 85°C, this capacitor addresses high-ripple, high-capacitance needs in power electronics and industrial systems where durability and service life matter.

Key Features

• High Bulk Capacitance — 68 mF (68,000 µF) rated capacitance for energy storage and bulk filtering in power systems.
• Rated Voltage and Tolerance — 63 V rated voltage with ±20% capacitance tolerance (measured at 120 Hz, 20°C), providing clear electrical margins for design.
• High Ripple Current Capability — Supports 15 A at 120 Hz (low frequency) and 17.25 A at 100 kHz (high frequency), enabling effective ripple handling in DC bus and filtering applications.
• Leakage and Loss Characteristics — Specified leakage current of 5,000 µA (5 mA) and tan δ up to 0.3, documented per product specifications.
• Package and Mounting — Radial can with screw terminals and M5 hardware dimensions for secure mechanical and electrical connections; physical size φ63.5 × 100L (10 × 6.35 cm).
• Reliability and Lifetime — Endurance specified at 5,000 hours at 85°C; after this test the capacitance change remains within ±15% and leakage remains at or below the initial specified value (per LNR series endurance criteria).
• Environmental Compliance — RoHS compliant as specified in the product data.

Typical Applications

• Power supply bulk filtering — Large capacitance and high ripple-current ratings make the LNR1J683MSE suitable for DC bus smoothing and bulk energy storage in power supplies.
• Industrial power electronics — Robust screw-terminal mounting and long endurance at 85°C support installation in industrial controllers and converters requiring durable bulk capacitors.
• High-ripple systems — High low- and high-frequency ripple current capability addresses applications with significant AC ripple components across the DC link.

Unique Advantages

• Substantial energy storage: 68 mF (68,000 µF) provides large charge hold for smoothing and transient support in heavy-duty power designs.
• High ripple handling: Rated for up to 15 A (120 Hz) and 17.25 A (100 kHz), reducing temperature rise and improving lifetime under ripple-loaded conditions.
• Secure screw-terminal connection: Radial can with screw terminals and M5 hardware dimensions ensures reliable mechanical and electrical installation in equipment racks and power assemblies.
• Defined endurance performance: 5,000 hours at 85°C with documented post-test limits (capacitance within ±15% and leakage ≤ initial value) supports predictable long-term behavior.
• Wide operating temperature range: –40°C to 85°C accommodates a broad range of environmental conditions encountered in industrial and general-purpose installations.
• RoHS compliant packaging: Conforms to environmental requirements while supplied in cardboard packing for mass production handling.
