LNR1K683MSEN

The LNR1K683MSEN is an aluminum electrolytic capacitor in a screw-terminal can designed for general-purpose power applications. It delivers 68 mF (68,000 µF) capacitance at an 80 V rating in a φ63.5 × 140 mm package with radial screw terminals for secure, high-current connections.

Engineered for demanding ripple environments, this part combines high ripple-current capability, defined loss tangent, and a 5,000‑hour endurance at 85°C to provide robust energy-storage and smoothing performance in systems that require large bulk capacitance.

Key Features

• Capacitance & Voltage — 68 mF (68,000 µF) nominal capacitance with an 80 V rated voltage and ±20% tolerance, offering substantial bulk energy storage for DC bus and filtering roles.
• High Ripple Current — 15.5 A low-frequency ripple at 120 Hz and 17.82 A high-frequency ripple at 100 kHz, supporting applications with significant AC ripple on DC rails.
• Defined Loss Characteristics — tanδ (DF) specified at 0.3 (maximum) measured at 20°C and 120 Hz, enabling predictable dissipation behavior in design thermal budgets.
• Leakage Current — Rated leakage current of 5000 µA, specified for predictable standby and operating leakage performance.
• Endurance & Temperature — 5,000 hours life/endurance at 85°C with an operating temperature range from −40°C to +85°C, suitable for extended operation in controlled high-temperature environments.
• Mechanical & Mounting — Screw terminal radial can (φ63.5 body diameter) with secure screw connections and standard mounting bracket options for stable chassis attachment.
• Compliance & Packaging — RoHS‑compliant and supplied in cardboard packing; available in mass production quantities.

Typical Applications

• Power supply bulk smoothing — High capacitance (68 mF) and 80 V rating provide effective energy storage and voltage stabilization on DC rails.
• Ripple current handling — Specified 15.5 A (120 Hz) and 17.82 A (100 kHz) ripple capabilities support circuits with significant AC components superimposed on DC.
• Energy buffering — Large capacitance and robust endurance make the capacitor suitable for short-term energy buffering where sustained charge/discharge cycles occur.

Unique Advantages

• Large bulk capacitance: 68,000 µF delivers substantial energy storage in a single component, simplifying BOM and layout for high-capacitance designs.
• High ripple tolerance: Dual ripple-current specifications at low and high frequencies allow designers to quantify thermal and lifetime considerations across operating spectra.
• Predictable dissipation: Specified tanδ at 20°C/120 Hz (0.3) provides a clear basis for estimating power loss and thermal management needs.
• Extended endurance: 5,000 hours at 85°C provides a measurable life expectation for designs operating in elevated temperature environments.
• Robust mechanical connection: Screw-terminal radial can design and standard mounting brackets ensure secure electrical and chassis attachment for high-current applications.
• Production-ready supply: RoHS-compliant and available in mass production with cardboard packing for straightforward procurement and handling.
