LLS1V273MELC

The LLS1V273MELC is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LLS series, offering 27,000 µF of capacitance at a 35 V rating. Engineered for general-purpose power applications, it provides high bulk capacitance in a compact φ35 × 50 mm can with a radial, snap‑in mounting.

Designed as part of an 85°C-standard series, this capacitor supports prolonged ripple current operation and is suitable for power supply smoothing, bulk energy storage and other general-purpose DC systems that operate within a −40°C to +85°C range.

Key Features

• Capacitance & Voltage — 27,000 µF rated capacitance at 35 V, with a capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• Snap-in Terminal Package — Radial, can-type snap‑in termination for secure board mounting and mechanical stability in tray-packed deliveries.
• Ripple Current Handling — Rated low-frequency ripple current of 6.9 A at 120 Hz and high-frequency ripple current of 7.935 A at 50 kHz for demanding DC applications.
• Endurance — Specified to withstand 3,000 hours under rated ripple current at 85°C, per the LLS series endurance characterization.
• Leakage & Loss Characteristics — Leakage current specified at 2,910 µA; tangent of loss angle (tan δ) max 0.35 at 120 Hz, 20°C for the 35 V rating.
• Operating Temperature — Rated for operation from −40°C to +85°C, supporting a wide range of general-purpose environments.
• Regulatory — RoHS compliant.

Typical Applications

• Power Supplies — Bulk energy storage and smoothing on low-voltage (35 V) DC rails, benefiting from 27,000 µF capacitance and high ripple-current capability.
• Industrial Electronics — DC bus filtering and decoupling in industrial control equipment operating within −40°C to +85°C, leveraging the LLS series endurance at 85°C.
• UPS and Backup Systems — Hold-up and transient support in backup or auxiliary power modules where large capacitance and robust ripple handling are required.

Unique Advantages

• High Bulk Capacitance in a Compact Can — 27,000 µF packaged in a φ35 × 50 mm can provides substantial energy storage for compact designs.
• Strong Ripple Performance — Rated ripple currents of 6.9 A (120 Hz) and 7.935 A (50 kHz) reduce voltage fluctuation under dynamic loads.
• Endurance Under Load — Ability to withstand 3,000 hours at 85°C with rated ripple current supports long-term use in steady-state power applications.
• Engineered Loss and Leakage Characteristics — Specified tan δ (0.35 at 120 Hz, 20°C) and defined leakage current (2,910 µA) enable predictable behavior in design verification and thermal budgeting.
• Robust Mounting and Packaging — Snap‑in radial can format simplifies PCB retention; tray packing supports efficient assembly and handling.
• Regulatory Compliance — RoHS-compliant construction supports environmental requirements for many industrial and commercial products.
