LNR1H473MSE

The LNR1H473MSE is a screw-terminal aluminum electrolytic capacitor designed for high-capacitance, general-purpose power applications. It combines a 50 V rated voltage with 47,000 µF capacitance in a radial can with screw terminals (φ51 × 90 mm body) to deliver bulk energy storage and high ripple-current handling in systems requiring secure, bolted connections.

With an operating temperature range of −40°C to 85°C, 5,000 hours endurance at 85°C, and RoHS compliance, this part targets applications that need robust long-term smoothing and energy buffering with easy mechanical mounting and serviceability.

Key Features

• High Capacitance — 47,000 µF (47 mF) provides substantial bulk energy storage for smoothing and decoupling.
• Rated Voltage — 50 V rated voltage suitable for mid-voltage power rails and supply systems.
• Ripple Current Performance — Supports 8.6 A low-frequency ripple current at 120 Hz and 9.89 A high-frequency ripple current at 100 kHz, supporting demanding ripple environments.
• Loss and Leakage — Specified tan δ of 0.25 (measured at 20°C, 120 Hz) and a measured leakage current of 4,590 µA for predictable loss and standby current behavior.
• Endurance and Temperature Range — 5,000 hours life at 85°C and an operating range of −40°C to 85°C for long-term reliability under elevated temperature stress.
• Mechanical/Form Factor — Radial can with screw terminals (φ51 × 90 mm); screw-terminal design with standard three-leg bracket for φ51 variants provides secure mounting and easy electrical connection (M5 nominal bolt diameter for φ51).
• Tolerance and Polarization — ±20% capacitance tolerance and polarized construction for straightforward specification in DC power circuits.
• Packaging & Production — Cardboard packing and mass production status support volume procurement and handling.
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose power supplies — Bulk smoothing and energy buffering where high capacitance and high ripple-current capability are required.
• Industrial power systems — Secure screw-terminal mounting and robust ripple handling make this capacitor suitable for industrial DC buses and power modules.
• Energy storage and hold-up — Large capacitance and long endurance at 85°C provide dependable hold-up capacity for control and auxiliary power circuits.

Unique Advantages

• Substantial bulk capacitance: 47,000 µF provides large energy reserve per component, reducing the need for multiple smaller capacitors.
• High ripple-current handling: 8.6 A at 120 Hz and 9.89 A at 100 kHz reduce thermal stress and improve reliability in high-ripple environments.
• Screw-terminal mounting: Radial can with M5-compatible screw terminals and standard three-leg bracket (φ51) enables secure mechanical installation and low-resistance connections.
• Proven endurance: Rated for 5,000 hours at 85°C, supporting longer service life in elevated-temperature applications.
• Serviceable and production-ready: Cardboard packing and mass production status simplify procurement and assembly for volume builds.
• Regulatory compliance: RoHS status supports environmentally conscious designs and regulatory requirements.
