LNR1H154MSEB

The LNR1H154MSEB is a screw-terminal aluminum electrolytic capacitor offering 150,000 µF capacitance at a 50 V rating in a radial can with screw terminals. It is designed for general-purpose applications that require large bulk capacitance, high ripple-current capability, and secure screw-terminal mounting.

Key value propositions include high capacitance density (150 mF), rated ripple-current handling at both low and high frequencies, and a validated endurance of 5,000 hours at 85 °C for stable performance in demanding thermal environments.

Key Features

• High Bulk Capacitance — 150,000 µF (150 mF) nominal capacitance with ±20% tolerance, providing substantial energy storage for bulk smoothing and decoupling needs.
• Rated Voltage — 50 V rated voltage suitable for a wide range of power-electronic applications requiring mid-range DC voltage handling.
• Robust Ripple Current Capability — Ripple current ratings of 18.6 A at 120 Hz and 21.39 A at 100 kHz support sustained AC ripple under load.
• Endurance at Elevated Temperature — Specified life of 5,000 hours at 85 °C under DC bias plus rated ripple current, with limits on capacitance change, tan δ, and leakage current defined by the datasheet.
• Screw Terminal Package — Radial can with screw terminals for secure, low-resistance connections; φ76.2 mm diameter case with mounting bracket provisions and M5 nominal bolt diameter for terminals.
• Wide Operating Temperature Range — Rated for operation from −40 °C to +85 °C (for 10 to 100 V rated types; consistent with series specifications for 10 to 100 V), aligning with the declared operating environment for this 50 V unit.
• Electrical Characteristics — Specified tangent of loss angle (tan δ) of 0.55 and specified leakage current of 5,000 µA support predictable ESR and leakage behavior for design calculation.
• Compliance — RoHS-compliant construction as indicated in the product data.

Typical Applications

• General-purpose power systems — Intended for general-purpose electronic designs that require large bulk capacitance in a screw-terminal package.
• High-ripple environments — Suitable where rated ripple currents (18.6 A at 120 Hz, 21.39 A at 100 kHz) are required to manage AC ripple under DC bias.
• Extended-temperature operation — Applicable in systems that must operate reliably up to 85 °C with a lifecycle specification of 5,000 hours at that temperature.

Unique Advantages

• Significant energy storage: 150,000 µF nominal capacitance delivers large bulk storage to support voltage stabilization and hold-up functions.
• Mid-voltage versatility: 50 V rating fits common DC bus and power-rail designs without over-specifying voltage capability.
• High ripple-current tolerance: Explicit ripple-current ratings at both 120 Hz and 100 kHz enable designers to size capacitors based on measured ripple conditions across frequency ranges.
• Durability at temperature: 5,000-hour endurance at 85 °C with defined limits on capacitance change, tan δ increase, and leakage current ensures predictable long-term performance.
• Secure screw-terminal mounting: Radial can with screw terminals and φ76.2 mm case diameter with M5 nominal terminal bolts provides reliable mechanical and electrical connection for heavy-current applications.
• Regulatory alignment: RoHS-compliant construction simplifies environmental compliance for assemblies.
