LAQ2P271MELB25ZB

The LAQ2P271MELB25ZB is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power applications. It provides 270 µF capacitance at a 220 V rating in a compact radial can (φ30 × 25L) with snap-in mounting and tray packing for straightforward assembly.

Engineered for robust ripple handling and extended high-temperature endurance, this part targets equipment operating in voltage-fluctuating environments where high ripple current, safety features and long-life performance at elevated temperatures are required. The product is in mass production.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a 220 V rated voltage and ±20% tolerance (120 Hz, 20°C), suitable for smoothing and energy-storage roles in power circuits.
• High Ripple Current Capability — Rated ripple current of 1.0 A at 120 Hz (low frequency) and 1.2 A at 10 kHz (high frequency), enabling effective handling of both low- and high-frequency ripple components.
• Wide Operating Temperature — Rated for −25°C to +105°C operation with a guaranteed endurance of 2000 hours at 105°C under rated conditions.
• Loss Characteristics — Tangent of loss angle (tan δ) ≤ 0.20 at 120 Hz, 20°C, supporting predictable dissipation behavior in AC-biased applications.
• Leakage Current — Specified leakage current of 730 µA for predictable standby and bias current behavior after voltage application.
• Safety & Reliability — Designed with improved safety features for abnormally excessive voltage and a pressure-relief vent that operates without dangerous conditions such as ignition or fragmentation, per the series specification.
• Packaging & Mounting — Snap-in radial can package (φ30 × 25L) supplied in tray packing for ease of handling and automated insertion.
• Regulatory — Datasheet indicates compliance with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering and smoothing — 220 V rating, 270 µF capacitance and high ripple current support bulk filtering and smoothing in AC-DC and DC-DC power stages.
• Industrial equipment in fluctuating-voltage environments — Improved safety features and 105°C, 2000-hour endurance make this capacitor suitable for systems exposed to voltage transients and variable mains conditions.
• High-ripple DC bus and filter circuits — The combination of high ripple current capability and stable tan δ supports DC-link filtering and high-stress filtering applications.

Unique Advantages

• High-temperature endurance: 2000 hours at 105°C under rated ripple and DC bias ensures long-term stability in elevated-temperature installations.
• Robust ripple handling: 1.0 A (120 Hz) and 1.2 A (10 kHz) ripple ratings reduce the need for parallel capacitors to handle ripple currents.
• Compact snap-in package: φ30 × 25L radial can with snap-in terminals offers a space-efficient solution for board-level power stages and simplifies mounting.
• Predictable electrical behavior: Specified tan δ (≤0.20) and defined leakage current provide reliable thermal and electrical characterization for design margins.
• Safety-focused design: Pressure-relief venting and series-level safeguards against excessive voltage help mitigate risk in volatile-power environments.
• RoHS compliance (per datasheet): Conforms to applicable RoHS directives, aiding regulatory alignment for many equipment markets.
