LGU2C271MELY

The LGU2C271MELY from Nichicon is a snap‑in, radial aluminum electrolytic capacitor in the LGU series designed for general‑purpose power applications. It provides 270 µF capacitance at a 160 V rating in a compact φ20 × 25 mm can, and is optimized for sustained operation up to 105 °C.

This part combines a 3000‑hour endurance at 105 °C with measurable ripple and leakage specifications, making it suitable for designs that require verified high‑temperature life and predictable electrical behavior under DC bias and ripple current loading.

Key Features

• Capacitance & Voltage: 270 µF nominal capacitance at a rated voltage of 160 V.
• High‑temperature endurance: Endurance specified for 3000 hours at 105 °C when subjected to rated DC bias plus rated ripple current.
• Ripple current specifications: Low‑frequency ripple current 1.1 A at 120 Hz and high‑frequency ripple current 1.65 A at 50 kHz, enabling quantifiable handling of AC ripple across frequencies.
• Loss and leakage: tanδ ≤ 0.15 (measurement condition: 20 °C, 120 Hz) and leakage current specified at 620 µA, allowing predictable dissipation and leakage behavior.
• Operating temperature range: −40 °C to +105 °C, supporting a wide range of thermal environments.
• Mechanical and packaging: Snap‑in radial can (φ20 × 25 mm) provided in tray packing for board‑mount assembly; part status: mass production.
• RoHS compliance: Confirmed RoHS‑compliant construction per product data.

Typical Applications

• General‑purpose power electronics: Suited for power modules and assemblies that require a 270 µF capacitor at 160 V with defined ripple current capability and 105 °C endurance.
• Power supply filtering and smoothing: Use where reliable DC bias performance, controlled leakage, and defined tanδ at 120 Hz are needed to stabilize rails and reduce ripple.
• High‑temperature environments: Appropriate for equipment operating up to 105 °C where a 3000‑hour life rating under rated ripple and bias is required.

Unique Advantages

• Verified high‑temperature life: 3000‑hour endurance at 105 °C provides documented reliability for long‑term operation in hot environments.
• Quantified ripple handling: Specified ripple currents at both 120 Hz and 50 kHz let designers evaluate thermal and electrical margins across frequency ranges.
• Predictable electrical behavior: Defined tanδ (≤ 0.15 at 20 °C, 120 Hz) and measured leakage current give clear parameters for loss and standby current planning.
• Compact snap‑in package: φ20 × 25 mm radial can with snap‑in terminals enables secure board mounting and straightforward mechanical integration.
• Production readiness: Tray packing and mass‑production status support volume manufacturing and supply chain planning.
• Regulatory compliance: RoHS compliance ensures suitability for applications requiring restricted‑substance adherence.

Why Choose LGU2C271MELY?

LGU2C271MELY positions itself as a practical, specification‑driven choice for designs that demand a 270 µF, 160 V aluminum electrolytic capacitor with documented high‑temperature endurance and quantified ripple performance. Its combination of a compact snap‑in can, defined tanδ and leakage figures, and explicit ripple current ratings makes it suitable for engineers who need verifiable electrical and thermal behavior rather than estimated performance.

This part is ideal for teams and projects focused on reliability and predictable lifecycle performance in general‑purpose power electronics and filtering applications, benefiting from Nichicon’s production readiness and RoHS‑compliant materials.
