LNR1C473MSE

The LNR1C473MSE is a screw-terminal aluminum electrolytic capacitor delivering 47,000 µF nominal capacitance at a 16 V rating in a radial can with screw terminals (φ35×80L). Designed for general-purpose electronic power systems, it provides high bulk capacitance in a robust screw-terminal package.

Key attributes visible in the datasheet include an operating temperature range of −40 °C to +85 °C, 5,000 hours endurance at 85 °C under rated DC bias plus ripple, and RoHS compliance—making it suitable for designs that require long-term, high-capacitance energy storage with secure mechanical terminals.

Key Features

• Capacitance & Voltage — 47,000 µF nominal capacitance with a rated voltage of 16 V and capacitance tolerance of −20% to +20%.
• Mounting & Package — Screw terminal radial can (φ35×80L) provides secure, robust electrical and mechanical connection for high-current terminations.
• Temperature Range — Rated for operation from −40 °C to +85 °C (series range listed in datasheet); suitable for environments within that span.
• Endurance — Specified to meet performance after 5,000 hours at 85 °C with DC bias plus rated ripple current (capacitance change within ±15% of initial value).
• Ripple Current — 6.4 A at 120 Hz and 7.36 A at 100 kHz to support AC ripple and high-frequency decoupling under rated conditions.
• Leakage Current Specification — Leakage after 5 minutes at rated voltage is limited to not more than 3√(C·V) µA or 5 mA (whichever is smaller), per datasheet formula.
• Reliability Metrics — Endurance and shelf-life limits defined in the datasheet: capacitance, tan δ and leakage current requirements are specified after endurance and shelf-life tests.
• Regulatory Status — RoHS compliant as indicated in the product data.

Typical Applications

• General-Purpose Power Systems — For designs that require large bulk capacitance and screw-terminal connections in power rails and DC buses.
• Energy Storage & Hold-Up — Where high capacitance and rated ripple current are needed within the specified temperature and endurance limits.
• Industrial Electronics — Fits applications that demand robust screw-terminal mounting and long endurance at elevated operating temperatures.

Unique Advantages

• Substantial Bulk Capacitance: 47,000 µF nominal provides significant energy reservoir for smoothing and DC bus stabilization within the 16 V rating.
• Screw-Terminal Robustness: Radial can with screw terminals (φ35×80L) enables secure, low-resistance connections for high-current installations.
• Defined Endurance: 5,000 hours at 85 °C with DC bias plus rated ripple current—specifications for capacitance, tan δ and leakage are provided to quantify long-term behavior.
• High Ripple Capability: Ripple current ratings at both low and high frequencies (6.4 A at 120 Hz, 7.36 A at 100 kHz) allow designers to size the part against expected AC stress.
• Clear Leakage Limit: Datasheet leakage-current formula (3√(C·V) µA or 5 mA max) provides a verifiable limit for selection and margin calculations.
• RoHS Compliance: Conforms to RoHS requirements for lead-free manufacturing flows.
