LNR1E683MSE

The LNR1E683MSE is an aluminum electrolytic capacitor in a screw‑terminal, radial can package that provides 68,000 µF of capacitance at a 25 V rating. It is designed for general‑purpose power applications that require substantial bulk energy storage and reliable screw‑terminal connections.

Key electrical characteristics include a capacitance tolerance of ±20%, low‑frequency ripple current of 9.4 A (120 Hz), high‑frequency ripple current of 10.81 A (100 kHz), and a rated endurance of 5,000 hours at 85°C. The part is RoHS compliant and intended for mass production use.

Key Features

• High Capacitance (68,000 µF) — Provides large bulk energy storage for hold‑up, smoothing and decoupling in power systems.
• 25 V Rated Voltage — Specified for low‑voltage DC rails requiring substantial capacitance.
• Robust Ripple Handling — Supports 9.4 A ripple at 120 Hz and 10.81 A at 100 kHz, enabling effective ripple suppression across low and high frequencies.
• Endurance at Elevated Temperature — Rated for 5,000 hours at 85°C under DC bias plus rated ripple current per the series specification.
• Screw Terminal Mounting & Radial Can — Screw terminals provide secure electrical and mechanical connection; package dimensions are φ35 × 120 mm (L), suitable for through‑hole panel or chassis mounting.
• Polarized with Defined Leakage and Tolerance — Polar capacitor with leakage current of 3,910 µA and capacitance tolerance of ±20% for predictable design margins.
• Wide Operating Temperature — Specified for −40°C to +85°C operation.
• RoHS Compliant — Meets RoHS environmental requirements for lead‑free production.

Typical Applications

• General‑purpose power systems — Bulk energy storage and smoothing for circuits that require a high capacitance, screw‑terminal connection and sustained ripple handling.
• Power supply hold‑up and filtering — Large capacitance and defined ripple current ratings make the part suitable for hold‑up and filtering duties in low‑voltage DC supplies.
• Industrial and commercial equipment — Use where long endurance at 85°C, secure screw‑terminal mounting, and RoHS compliance are required for production designs.

Unique Advantages

• Large energy storage in a compact can — 68,000 µF at 25 V delivers significant bulk capacitance while fitting a φ35 × 120 mm radial can footprint.
• Dual‑frequency ripple capability — Rated ripple currents at both 120 Hz and 100 kHz let designers address low‑frequency and high‑frequency ripple without multiple capacitor types.
• Long, specified life at elevated temperature — 5,000 hours endurance at 85°C under rated conditions provides predictable long‑term performance for production deployments.
• Secure electrical connection — Screw‑terminal format simplifies high‑current terminations and mechanical retention compared with leaded alternatives.
• Predictable electrical parameters — Defined leakage current (3,910 µA) and ±20% capacitance tolerance support reliable margining during design and testing.
• Regulatory compliance — RoHS compliance supports lead‑free manufacturing requirements.
