LNR1A154MSEN

The LNR1A154MSEN is an aluminum electrolytic capacitor in a screw‑terminal, radial can package designed for general‑purpose power applications. It provides high bulk capacitance (150,000 µF) at a 10 V rated voltage, with a compact φ51 × 80 mm body and screw‑terminal mounting for secure electrical and mechanical connection.

Key attributes include high ripple current capability at both low and high frequencies, a -40 °C to +85 °C operating range, and a 5,000‑hour endurance rating at 85 °C—features that make it suitable for demanding power smoothing and energy storage roles in general‑purpose equipment.

Key Features

• High Capacitance — 150,000 µF (150 mF) of capacitance for bulk energy storage and extended hold‑up in low‑voltage power systems.
• Rated Voltage and Tolerance — 10 V rated voltage with capacitance tolerance of -20% to +20% (measured at 120 Hz, 20 °C).
• Ripple Current Performance — Low‑frequency ripple current of 10.7 A (120 Hz) and high‑frequency ripple current of 12.3 A (100 kHz), supporting effective smoothing across a range of switching and line conditions.
• Loss Angle (tan δ) — tan δ = 0.9 (measured at 20 °C, 120 Hz), providing a defined dissipation characteristic for thermal and loss budgeting in designs.
• Endurance and Temperature Range — Rated for 5,000 hours at 85 °C with an operating range from -40 °C to +85 °C, enabling reliable long‑term use under elevated ambient conditions.
• Low Leakage Current — Specified leakage current of 3,670 µA; series specification also references the standard leakage limit of 3√(C·V) µA or 5 mA after 5 minutes.
• Robust Mechanical Package — Radial can with screw terminals and available mounting brackets for φ51 and larger bodies, using M5 nominal terminal bolts for secure connections.
• Regulatory — RoHS compliant.

Typical Applications

• Power supply bulk smoothing — Large capacitance and high ripple current support energy buffering and voltage stabilization in general‑purpose power supplies.
• DC bus / energy storage — High capacitance at low voltage for hold‑up and transient suppression in DC bus circuits.
• Industrial electronics — Screw‑terminal mounting and robust endurance make it suitable for general‑purpose industrial equipment requiring reliable bulk capacitance.

Unique Advantages

• Substantial bulk energy capacity — 150,000 µF at 10 V reduces dependence on multiple smaller capacitors and simplifies BOM for low‑voltage designs.
• Wide ripple bandwidth — Specified ripple currents at both 120 Hz and 100 kHz address smoothing needs across legacy and switching power environments.
• Long endurance at elevated temperature — 5,000 hours at 85 °C provides predictable performance and lifecycle planning for equipment operating at higher ambient temperatures.
• Screw‑terminal mounting — Robust electrical and mechanical connection suited to higher current paths and repeated serviceability.
• Clear electrical loss characteristic — Specified tan δ (0.9 at 20 °C, 120 Hz) supports accurate thermal and dissipation calculations during design.
• RoHS compliance — Aligns with environmental requirements for modern equipment assemblies.
