LNR1A154MSEB

The LNR1A154MSEB is a screw‑terminal aluminum electrolytic capacitor designed for general‑purpose power applications requiring very large capacitance and robust ripple handling. Its radial can with screw terminals and high-capacitance construction make it suitable where bulk energy storage and sustained ripple currents are required.

Key values include 150,000 µF capacitance at 10 V, a rated operating temperature range of −40 °C to 85 °C, and an endurance rating of 5,000 hours at 85 °C—offering designers predictable long‑term performance in industrial and commercial electronic systems.

Key Features

• Capacitance & Voltage — 150,000 µF (150 mF) rated at 10 V with ±20% tolerance, providing substantial bulk energy storage for DC smoothing and decoupling.
• High Ripple Current — Supports 10.7 A at 120 Hz (low frequency) and 12.3 A at 100 kHz (high frequency), enabling sustained ripple handling in power conversion and filtering circuits.
• Endurance & Reliability — 5,000 hours lifetime at 85 °C under rated DC bias plus ripple current, with specified limits for capacitance change, tan δ, and leakage current after endurance testing.
• Leakage & Loss Characteristics — Specified leakage current of 3,670 µA and a tangent of loss angle (tan δ) of 0.9, allowing predictable loss and leakage behavior for system design and thermal budgeting.
• Package & Mounting — Radial can with screw terminals for secure bolted electrical connections; body diameter φ51 mm, length 80 mm (approx. 8 × 5.1 cm), and standard mounting bracket options for φ51 and larger sizes.
• Environmental & Compliance — RoHS compliant and rated for operation from −40 °C to +85 °C.
• Polarized Design — Polarized aluminum electrolytic construction for DC applications where large capacitance polarity is managed in the circuit.

Typical Applications

• General‑purpose power filtering — Bulk smoothing and decoupling in power supplies and industrial electronics where large capacitance reduces voltage ripple.
• Bulk energy storage — Local energy reservoir for systems requiring short‑term energy buffering and stable DC rails.
• Power conversion subsystems — Support for converters and inverters that demand sustained ripple current capability at both low and high frequencies.

Unique Advantages

• Massive capacitance in a compact can: 150,000 µF provides high charge storage density to minimize external board-level capacitor counts.
• Dual-frequency ripple capability: High ripple ratings at 120 Hz and 100 kHz help ensure reliable operation across both low‑frequency rectifier ripple and higher‑frequency switching environments.
• Designed for long service life: 5,000 hours at 85 °C under rated conditions gives predictable aging characteristics for longer field life.
• Screw terminal robustness: Bolted electrical connections simplify high-current terminations and improve mechanical reliability in rugged installations.
• Wide temperature range: −40 °C to +85 °C operation supports deployment across a broad set of industrial and commercial environments.
• RoHS compliant: Meets environmental conformity requirements for regulated markets.
