LAQ2D271MELZ25

The LAQ2D271MELZ25 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LAQ series, offering 270 µF capacitance at a 200 V rating. Designed for general-purpose power applications, this snap‑in, radial can capacitor delivers robust ripple handling and thermal endurance for demanding electronic power systems.

Key value comes from its combination of 200 V capability, compact φ22 × 25 mm sizing, and endurance tested at elevated temperature (2000 hours at 105°C), making it suitable for industrial and power‑supply designs where voltage, ripple and long‑term stability matter.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Snap‑In Mounting — Snap‑in terminal radial can (snap‑in) package for secure mechanical retention and straightforward board‑mount assembly.
• Ripple Handling — Rated ripple current of 1.0 A at 120 Hz (low frequency) and 1.2 A at 10 kHz (high frequency) for effective smoothing in power circuits.
• Leakage and Loss — Low leakage current of 0.69 mA (specified for this size) with tan δ meeting the series limit (0.20 max at 120 Hz, 20°C).
• Thermal Endurance — Endurance rated for 2000 hours at 105°C under D.C. bias plus rated ripple current; after the test, capacitance change remains within ±20% and leakage current stays within initial limits.
• Compact Mechanical Profile — Size φ22 × 25 mm (L: 25 mm × D: 22 mm) suited to space‑constrained power modules and enclosures.
• Safety Features — Built‑in pressure relief vent designed to operate under abnormal conditions to avoid dangerous outcomes such as flames or case dispersion.

Typical Applications

• Industrial Power Supplies — Bulk and smoothing capacitor for 200 V rails in industrial converters and power modules where sustained ripple handling and thermal endurance are required.
• UPS and Battery Systems — Energy storage and smoothing for intermediate DC links and filter stages operating at higher voltages.
• Motor Drives and Inverters — Filtering and decoupling in inverter and motor‑control power stages that demand reliable performance at elevated temperatures.
• General‑Purpose Power Electronics — Voltage buffering and ripple suppression in a wide range of power electronics where a compact, high‑voltage electrolytic is needed.

Unique Advantages

• High‑voltage capability: 200 V rating supports higher DC bus designs without paralleling lower‑voltage parts, simplifying BOM and layout.
• Proven thermal endurance: 2000 hours at 105°C (with specified post‑test limits) provides confidence for designs exposed to sustained elevated operating temperatures.
• Robust ripple performance: 1.0 A (120 Hz) and 1.2 A (10 kHz) ripple ratings enable effective smoothing across both low and high frequency ripple components.
• Secure snap‑in mounting: Snap‑in terminal and radial can package improve mechanical retention in vertical assemblies and simplify insertion into panel or chassis subassemblies.
• Compact footprint: φ22 × 25 mm dimensions allow integration into tight power supply layouts while maintaining required capacitance and voltage.
• Series safety design: Pressure relief venting reduces risk under abnormal conditions, aiding safer system behavior.
