LNR1K103MSEN

The LNR1K103MSEN from Nichicon is a screw‑terminal aluminum electrolytic capacitor in the LNR series, offering 10,000 µF nominal capacitance at 80 V. Designed for general‑purpose power applications, it provides high bulk capacitance, robust screw‑terminal connections, and an endurance rating suited to sustained operation.

Key design attributes include a wide operating temperature range of −40 °C to 85 °C, a 5,000‑hour endurance at 85 °C under rated bias and ripple, and specified ripple and leakage characteristics for reliable power filtering and energy buffering.

Key Features

• Capacitance & Rated Voltage — 10,000 µF nominal capacitance at 80 V rated voltage, with ±20% tolerance (measured at 120 Hz, 20 °C).
• Screw‑Terminal Package — Radial can with screw terminals for secure, low‑impedance connections typical of chassis‑mounted power capacitors; package size φ35 × 80 mm length.
• Ripple Current Capability — Low‑frequency ripple current 4.2 A (120 Hz) and high‑frequency ripple current 4.83 A (100 kHz), specified to support sustained AC ripple under bias.
• Loss Tangent (tan δ) — Specified tan δ of 0.2 (measured at 20 °C, 120 Hz), useful for evaluating dissipation under AC conditions.
• Leakage Current — Measured leakage current 2,680 µA; datasheet leakage limit follows the industry formula ≤ 3√(C·V) (µA) or 5 mA, whichever is smaller.
• Temperature & Endurance — Operating temperature range −40 °C to 85 °C with endurance of 5,000 hours at 85 °C under DC bias plus rated ripple current; post‑endurance limits: capacitance change within ±15%, tan δ ≤ 175% of initial, leakage current ≤ initial.
• Compliance & Packaging — RoHS compliant and packaged in cardboard; product is in mass production.

Typical Applications

• General‑purpose power circuitry — Bulk energy storage and smoothing where a 10,000 µF, 80 V capacitor with high ripple capability is required.
• Industrial power supplies — Screw‑terminal mounting supports secure connections for chassis‑mounted or high‑current power systems.
• Stationary power filtering — Designed for long operational life at elevated ambient temperatures (5,000 hours at 85 °C) in sustained bias conditions.

Unique Advantages

• Substantial bulk capacitance: 10,000 µF at 80 V provides significant energy storage for smoothing and hold‑up in power circuits.
• High ripple handling: Specified LF and HF ripple currents (4.2 A @120 Hz, 4.83 A @100 kHz) support applications with continuous AC ripple under DC bias.
• Robust mechanical connection: Screw‑terminal construction simplifies high‑current wiring and ensures secure chassis or bracket mounting.
• Durability under load: 5,000‑hour endurance at 85 °C with defined post‑endurance limits provides predictable aging behavior for design planning.
• Measurable dissipation characteristics: Specified tan δ (0.2 at 20 °C, 120 Hz) and documented leakage current enable accurate thermal and loss budgeting.
• Regulatory and production readiness: RoHS compliant and in mass production for volume procurement and deployment.
