LNR1A104MSEN

The LNR1A104MSEN from Nichicon is a screw‑terminal aluminum electrolytic capacitor in the LNR series, designed for general‑purpose power applications that require large bulk capacitance. Its radial can with screw terminals provides a robust electrical and mechanical connection for high ripple current environments.

With a nominal capacitance of 100,000 µF (100 mF), a rated voltage of 10 V, and an operating temperature range of −40 °C to +85 °C, this capacitor delivers substantial energy storage and ripple handling for demanding power circuitry while meeting RoHS environmental compliance.

Key Features

• Capacitance & Tolerance — 100,000 µF (100 mF) nominal capacitance with ±20% tolerance at 120 Hz, 20 °C.
• Rated Voltage & Polarization — 10 V rated voltage; polarized design for DC applications.
• High Ripple Current Capacity — Low‑frequency ripple current of 8.8 A (120 Hz) and high‑frequency ripple current of 10.12 A (100 kHz), supporting heavy ripple environments.
• Endurance & Stability — Rated life of 5,000 hours at 85 °C with specified limits: capacitance change within ±15% after endurance, tan δ ≤175% of initial spec, and leakage current not exceeding initial specified value.
• Leakage Current — Initial leakage current specified at 3,000 µA (after 5 minutes’ application of rated voltage or per the series specification).
• Temperature Range — Operating from −40 °C to +85 °C (for 10 V rating as per series specification).
• Mechanical & Mounting — φ35 × 100 mm can size (L: 10 cm × D: 3.5 cm) with screw terminal radial can package for secure, low‑impedance connections.
• Packaging & Marking — Supplied in cardboard packing; sleeve marking printed in black on light blue sleeve as per series marking convention.
• Environmental Compliance — RoHS compliant.

Typical Applications

• General Power Filtering — Bulk capacitance for smoothing and energy storage in DC power rails where high capacitance and ripple handling are required.
• Power Supply Support — Decoupling and hold‑up applications in power supplies that operate within the −40 °C to +85 °C temperature range.
• High‑Ripple Circuits — Circuits that impose continuous ripple currents up to the specified 8.8 A (120 Hz) and 10.12 A (100 kHz) levels benefit from the LNR1A104MSEN’s capability.

Unique Advantages

• Very High Bulk Capacitance: 100,000 µF provides substantial energy storage in a single radial can, reducing the need for multiple smaller capacitors.
• Robust Ripple Handling: Measured ripple current ratings at both low and high frequencies (8.8 A @ 120 Hz, 10.12 A @ 100 kHz) support applications with significant AC content on DC rails.
• Long Endurance at Elevated Temperature: 5,000 hours life at 85 °C with defined limits on capacitance change, tan δ, and leakage current for predictable long‑term performance.
• Screw Terminal Mounting: Radial can with screw terminals enables secure, low‑resistance electrical connections for high‑current paths and easy replacement or servicing.
• Clear Specification and Marking: Marked sleeve and series documentation help ensure correct part identification and traceability during assembly.
• RoHS Compliant: Meets environmental restrictions for materials, simplifying regulatory compliance.
