LNR1E154MSEN

The LNR1E154MSEN is an aluminum electrolytic, screw-terminal capacitor from Nichicon’s LNR series designed for general-purpose power applications. It provides very high bulk capacitance (150,000 µF) at a 25 V rating in a radial can with screw terminals, targeting designs that require large energy storage and reliable ripple handling.

Engineered for continuous operation up to 85°C, this part combines high ripple-current capability with a long endurance rating to support industrial and power-electronic applications that demand sustained performance under DC bias and ripple load.

Key Features

• High Capacitance — 150,000 µF nominal capacitance (±20% tolerance) for substantial bulk energy storage and smoothing in DC systems.
• Rated Voltage — 25 V rated voltage suitable for low-voltage power rails and DC-link applications requiring large capacitance.
• Robust Ripple Performance — Low-frequency ripple current 15.3 A at 120 Hz and high-frequency ripple current 17.595 A at 100 kHz for effective ripple absorption across a wide frequency range.
• Endurance and Temperature Range — 5000 hours life at 85°C; operating temperature range −40°C to +85°C to meet demanding thermal environments.
• Leakage and Loss Characteristics — Specified leakage current up to 5000 µA and tan δ specified (measurement at 120 Hz, 20°C) to help predict loss and self-heating under bias.
• Screw Terminal Package — Radial can with screw terminals and standard mounting brackets (3-leg bracket for φ51 body as supplied); terminal hardware designed for secure bolted connections (nominal bolt diameter M5 for φ51 bodies).
• Physical Size — Large-format can: φ51 × 120 mm (L: 12 cm × D: 5.1 cm), suitable where high capacitance per component is required.
• RoHS Compliant — Meets RoHS requirements for environmental compliance.

Typical Applications

• General-purpose power smoothing — Provides bulk capacitance for DC power rails and power-supply output filtering where large energy storage at 25 V is needed.
• DC-link and energy buffer — Suited for DC-link or intermediate storage in power conversion systems that demand high ripple-current capability at low voltages.
• Industrial power electronics — Appropriate for industrial control and power modules that require long endurance at elevated temperatures and secure screw-terminal connections.

Unique Advantages

• Large single-component capacitance: 150,000 µF reduces the number of parallel parts needed, simplifying BOM and board layout for high-capacitance designs.
• High ripple handling: Rated ripple currents at both low and high frequencies support effective suppression of AC ripple across a wide spectrum, minimizing thermal stress under ripple load.
• Durable screw-terminal mounting: Screw terminals and standard bracketing (3-leg for φ51) deliver mechanically secure, low-impedance connections for heavy-current applications.
• Extended endurance at elevated temperature: 5000 hours at 85°C provides predictable long-term performance for designs exposed to sustained thermal stress.
• Clear electrical limits: Specified leakage current, tan δ, and ±20% capacitance tolerance enable straightforward design verification and margining.
• Regulatory compliance: RoHS status provides environmental conformance for global procurement.
