LNR1K224MSEB

The LNR1K224MSEB is an aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose power applications. It delivers very high capacitance (220,000 µF) at an 80 V rating with robust ripple-current capability for demanding power-conditioning and bulk energy-storage roles.

Built to the Nichicon LNR series specifications, this screw-terminal device combines high capacitance, long endurance at elevated temperature, and a heavy-duty mounting style for reliable integration into power assemblies.

Key Features

• High Capacitance: 220,000 µF (220 mF) nominal capacitance for substantial energy reserve and smoothing.
• Rated Voltage: 80 V DC rating suitable for mid-voltage power rails.
• Ripple Current Performance: Low-frequency ripple current 28.9 A (120 Hz) and high-frequency ripple current 33.23 A (100 kHz), enabling effective AC ripple handling across frequencies.
• Loss Characteristics: tan δ (loss factor) 0.4 at 20°C, measured at 120 Hz, for predictable dissipation behavior.
• Endurance at Elevated Temperature: Rated for 5,000 hours at 85°C; per LNR series endurance, capacitance change remains within ±15% after the specified endurance test when DC bias plus rated ripple current is applied.
• Leakage Current: Specified at 5,000 µA (5 mA) after rated voltage application, consistent with the product's large-capacitance class.
• Operating Temperature Range: –40°C to +85°C for broad environmental tolerance.
• Mechanical & Mounting: Screw terminal radial-can package (φ90 × 220L); standard terminal bolts per LNR series for φ90 use M5 hardware and three-leg bracket mounting as provided.
• Tolerance & Polarity: Capacitance tolerance ±20% at 120 Hz, 20°C; polarized device.
• Compliance & Packaging: RoHS compliant; supplied in cardboard packing. Product status: Mass Production.

Typical Applications

• General-purpose power modules: Provides bulk capacitance and ripple filtering where high capacitance and current handling are needed.
• Power conditioning and smoothing: Supports DC-link and smoothing roles by reducing voltage ripple under heavy ripple-current loads.
• Industrial power assemblies: Suited for assemblies requiring screw-terminal mounting and durable, long-life capacitor performance at elevated temperatures.

Unique Advantages

• Substantial energy storage: 220,000 µF capacitance delivers significant bulk charge capacity for smoothing and transient support.
• High ripple-current capability: 28.9 A (120 Hz) and 33.23 A (100 kHz) ratings reduce heating and improve stability under AC stress.
• Long-term thermal endurance: 5,000 hours at 85°C with defined post-test limits (capacitance within ±15%, tan δ ≤175% of initial spec, leakage ≤ initial spec) for predictable lifecycle behavior.
• Robust screw-terminal mounting: Radial can with screw terminals and M5 nominal bolts (for φ90 bodies) simplifies mechanical integration into heavy-current power assemblies.
• Clear electrical spec set: Defined leakage current, tan δ, tolerance, and polarized construction make selection and design-in straightforward.
• Production readiness: RoHS-compliant and in mass production with cardboard packing for manufacturing supply chains.
