LAQ2G271MELC35

The LAQ2G271MELC35 is a snap‑in terminal aluminum electrolytic capacitor in Nichicon’s LAQ series, designed for general‑purpose power applications. It combines a compact radial can snap‑in package with high‑voltage capability and a 105°C permissible abnormal voltage rating to support demanding thermal and electrical environments.

With a rated capacitance of 270 µF at 400 V and a compact footprint (L: 3.5 × D: 3.5 cm, height seated max 1.378 inch), this part is intended for designers requiring reliable bulk capacitance, established endurance, and snap‑in mounting for robust board retention.

Key Features

• Core Dielectric and Capacitance — 270 µF rated capacitance with ±20% tolerance at 120 Hz, 20°C, providing predictable bulk energy storage for power circuits.
• High Voltage Rating — 400 V rated voltage suitable for high‑voltage power rails and applications that require elevated DC working voltage.
• Operating Temperature & Endurance — Specified for −25°C to +105°C with endurance validated to 2000 hours at 105°C under DC bias plus rated ripple current; capacitance change remains within ±20% after the endurance test.
• Ripple Current Performance — Rated ripple current of 1.3 A at 120 Hz and 1.495 A at 100 kHz to support AC superposition and switching power applications.
• Leakage Current and Loss Tangent — Leakage current meets I ≤ 3√C (µA) after 5 minutes at 20°C; tan δ specified to 0.20 max at 120 Hz, 20°C.
• Package & Mounting — Radial, can‑type snap‑in terminal package for secure mechanical retention and easy vertical board insertion.
• Safety Features — Pressure relief vent designed to operate under abnormal conditions to avoid dangerous outcomes such as flames or case dispersion.

Typical Applications

• Power supply filtering — Bulk smoothing and energy storage on high‑voltage DC rails where 400 V rated capacitance is required.
• Industrial power electronics — General‑purpose power systems and industrial equipment that need high‑temperature endurance and snap‑in mounting for secure installation.
• AC/DC conversion stages — Filtering and ripple management in rectifier and converter stages operating at elevated temperatures.

Unique Advantages

• High‑voltage bulk capacitance: 270 µF at 400 V provides substantial energy storage in a single component, simplifying BOM and layout for high‑voltage designs.
• Compact snap‑in form factor: Radial can with snap‑in terminals delivers secure board retention while minimizing footprint (L: 3.5 × D: 3.5 cm).
• Designed for elevated temperatures: Rated to 105°C with a 2000‑hour endurance specification, enabling use in thermally demanding environments.
• Defined electrical stability: Leakage current and tan δ specifications (I ≤ 3√C µA; tan δ ≤ 0.20) support predictable behavior after installation and during operation.
• Safety mitigation: Pressure relief vent and defined safety test conditions for 400 V/270 µF configurations reduce risk under abnormal voltage stress.
