LGL2W271MELZ45

The LGL2W271MELZ45 is a snap-in terminal type aluminum electrolytic capacitor designed for ultra-smaller-sized, high-voltage applications. It provides 270 µF capacitance at a rated voltage of 450 V and is built for through-hole snap-in mounting in radial can packages.

Engineered for general-purpose use, this capacitor supports an operating temperature range from −25 °C to +105 °C and a specified endurance of 2000 hours at 105 °C, offering a combination of high-voltage capability, compact footprint, and elevated temperature performance.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a rated voltage of 450 V and a tolerance of −20% to +20%.
• High-Temperature Endurance — Rated to operate up to 105 °C with an endurance specification of 2000 hours at 105 °C under D.C. bias plus rated ripple current.
• Snap-In, Radial Can Package — Snap-in mounting type in a radial, can-style package suitable for through-hole assemblies and secure PCB retention.
• Compact, Ultra-Smaller-Sized Form — Size dimension L: 4.5 × D: 2.2 cm, designed for space-conscious layouts while delivering 450 V capability.
• Ripple Current Performance — Rated ripple handling of 930 mA at 120 Hz and 1.33 A at 50 kHz to support applications with AC ripple stress.
• Wide Temperature Range — Operating range from −25 °C to +105 °C with low-temperature impedance characteristics documented for reliable cold-start behavior.
• Endurance and Stability — Endurance limits specify capacitance change within ±20%, tan δ within 200% of initial value, and leakage current not exceeding initial specified value after endurance testing.
• Identification — Marked with white letters on a black sleeve for clear part identification.

Typical Applications

• General Purpose (High-Voltage Systems) — Suitable for general-purpose circuits requiring 450 V working voltage and 270 µF capacitance.
• General Purpose (Elevated Temperature Environments) — Intended for applications that require operation up to 105 °C and validated endurance at that temperature.
• General Purpose (Through-Hole / Snap-In Assemblies) — Designed for secure snap-in mounting in radial can form factors for traditional PCB assembly methods.
• General Purpose (Ripple-Loaded Circuits) — Applicable where rated ripple currents (930 mA at 120 Hz, 1.33 A at 50 kHz) are required for AC ripple handling.

Unique Advantages

• High-Voltage Capability: 450 V rating enables use in higher-voltage general-purpose designs without upsizing the component.
• Compact High-Temperature Design: Ultra-smaller-sized package with 105 °C rating and 2000-hour endurance supports dense layouts in demanding thermal conditions.
• Robust Ripple Handling: Specified ripple current values at both low and high frequencies provide predictable performance under AC ripple stress.
• Reliable Endurance Specifications: Clear endurance criteria (capacitance, tan δ, leakage) after 2000 hours at 105 °C help predict long-term behavior in end products.
• Through-Hole Snap-In Mounting: Snap-in terminals provide strong mechanical retention for power assemblies and ease of PCB placement.
• Clear Part Identification: White-on-black sleeve marking simplifies inventory and assembly verification.
