LNR1A334MSEB

The LNR1A334MSEB is a screw-terminal, polarized aluminum electrolytic capacitor offering 330,000 μF (330 mF) nominal capacitance at a rated voltage of 10 V. It is a radial can with screw terminals engineered for general-purpose power applications that require large bulk capacitance and robust ripple-current handling.

With a rated operating temperature range of −40°C to +85°C and an endurance rating of 5000 hours at 85°C, this capacitor provides long-term stability for applications that demand sustained performance under elevated temperature and continuous ripple conditions.

Key Features

• High Capacitance — 330,000 μF (330 mF) nominal capacitance for substantial bulk energy storage and smoothing.
• Low Voltage Rating — Rated for 10 V, suitable where high capacitance at low voltage is required.
• High Ripple Current Capability — Supports 15.9 A at 120 Hz (low frequency) and 18.29 A at 100 kHz (high frequency) to handle continuous AC ripple loads.
• Screw Terminal Mounting — Radial can with screw terminals for secure, high-current connections and straightforward installation.
• Endurance and Temperature — 5000 hours life at 85°C and an operating range from −40°C to +85°C for sustained performance in warm environments.
• Leakage and Tolerance — Leakage current specified up to 5000 μA and capacitance tolerance of ±20% (at 120 Hz, 20°C).
• RoHS Compliant — Meets RoHS requirements.
• Physical Size — Body diameter 63.5 mm and length 100 mm (φ63.5×100L), packed in cardboard for bulk handling.

Typical Applications

• Power Supply Filtering — General-purpose smoothing and bulk energy storage in DC power supplies where large capacitance and high ripple capability are needed.
• DC Link and Energy Storage — Bulk capacitance for energy buffering and decoupling in systems that require sustained charge reservoirs at low voltage.
• Industrial Power Electronics — Use in general industrial equipment for stabilizing supply rails and absorbing load transients.

Unique Advantages

• Substantial Bulk Storage: 330,000 μF provides significant energy reserve for smoothing and transient support, reducing the need for multiple smaller capacitors.
• Robust Ripple Handling: High ripple current ratings at both low and high frequencies allow reliable operation under continuous AC ripple loads.
• Durability at Elevated Temperature: 5000-hour endurance at 85°C demonstrates sustained performance for long service life under thermal stress.
• Secure Mechanical and Electrical Connection: Screw terminals provide strong, low-resistance connections suitable for high-current paths and straightforward maintenance.
• Wide Operating Temperature Range: −40°C to +85°C supports deployment across a broad range of ambient conditions.
• Regulatory Compliance: RoHS compliance supports use in assemblies requiring restricted substances adherence.
