LGL2G271MELZ35

The LGL2G271MELZ35 is a snap‑in terminal aluminum electrolytic capacitor designed for general-purpose power applications. It delivers 270 µF capacitance at a 400 V rating in an ultra-smaller-sized snap‑in can, optimized for compact high‑voltage circuits.

Engineered for elevated ambient temperatures, this part supports an operating range of –25°C to +105°C and is specified for endurance under rated DC bias plus ripple current for 2000 hours at 105°C, providing predictable performance in demanding environments.

Key Features

• Electrical — 270 µF capacitance at 400 V with ±20% tolerance, suitable where high‑voltage capacitance is required.
• Ripple Handling — Rated ripple current of 910 mA at 120 Hz; high‑frequency ripple capability listed at 1.301 A at 50 kHz, with published frequency coefficients for ripple‑current scaling.
• Thermal & Reliability — Operating temperature range −25°C to +105°C and endurance specification of 2000 hours at 105°C with limits on capacitance change (±20%), tan δ (≤200% of initial), and leakage current (≤ initial).
• Loss & Low‑Temperature Performance — tan δ max 0.15 (measured at 120 Hz, 20°C, 400 V); impedance ratio Z(−25°C)/Z(+20°C) up to 8 for maintained performance at low temperature.
• Leakage Current — Specified leakage current follows I ≤ 3√CV (µA) after 5 minutes’ application of rated voltage at 20°C, providing a verifiable limit for design calculations.
• Mechanical & Mounting — Radial snap‑in can package (approx. 22 × 35 mm) for secure PCB mounting and compact board footprint.

Typical Applications

• High‑voltage power supplies — Bulk smoothing and filtering where 400 V rating and 270 µF capacitance support energy storage and ripple attenuation.
• Industrial power electronics — Local energy reservoir and decoupling in converters and inverters that require elevated temperature endurance and high ripple capability.
• UPS and backup systems — DC link and energy buffering roles benefiting from the part’s voltage rating, ripple current spec, and long endurance at 105°C.

Unique Advantages

• Compact high‑voltage solution: 270 µF at 400 V in an ultra-smaller-sized snap‑in can minimizes board area for high‑voltage capacitors.
• Designed for elevated temperatures: Rated to operate up to 105°C with a 2000‑hour endurance specification under rated stress, supporting reliability in hot enclosures.
• Predictable ripple performance: Published ripple current ratings at 120 Hz and 50 kHz plus frequency coefficients allow accurate thermal and lifetime calculations.
• Secure snap‑in mounting: Radial snap‑in termination simplifies mechanical retention and assembly for power‑dense PCBs.
• Measured electrical limits: Clear specifications for leakage current (I ≤ 3√CV), tan δ, and low‑temperature impedance give engineers data for robust designs.
