LLS2D271MELY

The LLS2D271MELY is an aluminum electrolytic capacitor in a snap-in terminal (radial can) package designed for general-purpose power applications. It provides 270 µF capacitance at a 200 V rated voltage with a ±20% tolerance and is built for robust ripple handling and long-term endurance.

Engineered for reliability in standard 85°C environments, this RoHS‑compliant unit delivers high ripple current capability across low and high frequencies, low leakage, and a 3000-hour endurance rating at 85°C—making it suitable for a range of industrial and electronic systems that require dependable bulk energy storage and smoothing.

Key Features

• Capacitance and Voltage — 270 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance for bulk energy storage and DC link applications.
• Snap-in Radial Can Package — Snap-in terminal (radial, can - snap-in) mounting for secure panel or chassis insertion and straightforward assembly.
• Endurance at Elevated Temperature — Rated for 3000 hours at 85°C under rated ripple current, supporting longevity in sustained thermal environments.
• High Ripple Current Capacity — 1390 mA at 120 Hz (low frequency) and 2085 mA at 50 kHz (high frequency) to support demanding ripple and decoupling requirements.
• Low Loss and Leakage — Tangent of loss angle (tan δ) of 0.15 at 20°C/120 Hz and leakage current specified at 690 µA, enabling efficient performance and predictable leakage behavior.
• Operating Temperature Range — −40°C to +85°C to accommodate a wide span of ambient conditions within the 85°C product category.
• Compact Footprint — Physical size φ20 × 25L (L: 2.5 cm × D: 2 cm) for space-conscious designs; supplied in tray packing for volume assembly.
• RoHS Compliance — Conforms to RoHS requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supply Bulk Filtering — Provides bulk capacitance and ripple smoothing for DC power rails in general-purpose power supplies and converters.
• Power Electronics — Suited for general-purpose power electronics where high ripple current capability and 200 V rating are required.
• Energy Buffering — Acts as an energy reservoir for systems needing short-term energy buffering or DC link stabilization.
• Industrial Equipment — Useful in industrial electronic equipment that operates within the −40°C to +85°C range and benefits from long endurance at 85°C.

Unique Advantages

• High-voltage, high-capacitance combination — 270 µF at 200 V provides substantial energy storage for higher-voltage circuits without increasing part count.
• Designed for long-term operation at 85°C — 3000-hour endurance under rated ripple current supports predictable service life in sustained thermal conditions.
• Strong ripple handling across frequencies — Specified ripple current at both 120 Hz and 50 kHz offers flexibility for AC and switching environments.
• Compact snap-in form factor — Radial snap-in can eases mechanical retention and assembly in rack or chassis-mounted power systems.
• Low loss and controlled leakage — tan δ = 0.15 (20°C, 120 Hz) and 690 µA leakage current deliver efficient energy management and stable leakage behavior.
• Regulatory alignment — RoHS compliance supports environmental and regulatory requirements for commercial and industrial electronic products.
