LNR2E103MSEB

The LNR2E103MSEB is a screw‑terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It delivers 10,000 µF capacitance at a 250 V rating in a radial can with screw terminals and is produced for mass production use.

With an operating temperature range of −25°C to 85°C, a 5,000‑hour endurance at 85°C, and high ripple current capability across low and high frequencies, this part is intended for bulk energy storage, smoothing and DC link roles in demanding power systems.

Key Features

• High Capacitance and Voltage — 10,000 µF at 250 V provides substantial bulk energy storage for DC filtering and smoothing.
• Robust Ripple Handling — Low‑frequency ripple current 11.8 A (120 Hz) and high‑frequency ripple current 14.16 A (100 kHz) for applications with significant AC ripple.
• Endurance and Temperature Range — Rated for 5,000 hours at 85°C with an operating range of −25°C to 85°C, supporting sustained thermal and electrical stress.
• Electrical Characteristics — Capacitance tolerance −20% to +20% and tangent of loss angle (tan δ) 0.2 measured at 20°C, 120 Hz.
• Leakage Current — Specified leakage current of 4,740 µA after initial application of rated voltage.
• Mechanical and Mounting — Radial can with screw terminals and supplied with standard three‑leg mounting brackets for body diameters ≥ φ51 mm; body dimension φ76.2 mm × 120 mm length.
• Packaging and Compliance — Cardboard packing and RoHS compliant; product is in mass production.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and output smoothing where 250 V rating and high capacitance reduce ripple and stabilize DC rails.
• Motor Drive DC Link — High ripple current capability and long endurance support decoupling and energy buffering in inverter and motor drive systems.
• Uninterruptible Power Supplies (UPS) — Large capacitance and robust leakage/ripple characteristics provide energy hold-up and filtering in backup power designs.
• Power Conversion Equipment — Suited for DC filtering and smoothing in converters and inverters that require high voltage and sustained ripple performance.

Unique Advantages

• Substantial Energy Storage: 10,000 µF at 250 V delivers significant capacitance for bulk filtering and DC link applications.
• Designed for High Ripple Environments: Specified ripple currents of 11.8 A (120 Hz) and 14.16 A (100 kHz) enable reliable operation under heavy AC ripple conditions.
• Long Endurance at Elevated Temperature: Rated 5,000 hours at 85°C, providing predictable lifetime performance in sustained thermal stress scenarios.
• Serviceable Screw‑Terminal Mounting: Screw terminals and standard three‑leg brackets simplify installation and secure electrical connections for high‑current paths.
• Clear Electrical Characterization: Defined tan δ (0.2 at 20°C, 120 Hz), capacitance tolerance (−20% to +20%), and measured leakage current (4,740 µA) allow straightforward design margin assessment.
• RoHS Compliant and Production‑Ready: Mass production status with cardboard packing supports procurement and integration at scale.
