LAQ2D122MELC40ZB

The LAQ2D122MELC40ZB is an aluminum electrolytic capacitor from Nichicon’s LAQ series featuring a snap‑in terminal radial can design. It provides 1.2 mF capacitance at a 200 V rating with a ±20% tolerance and is specified for general‑purpose power applications.

Engineered for sustained operation up to 105°C, this capacitor delivers multi‑amp ripple performance at both low and high frequencies, low leakage, and a 2,000‑hour endurance rating at 105°C—offering a reliable bulk energy storage and filtering option for 200 V circuits. It is supplied in tray packing for mass production needs.

Key Features

• Capacitance & Tolerance — 1.2 mF (1200 µF) with ±20% tolerance at 120 Hz, 20°C, suitable for bulk filtering and energy buffering in 200 V systems.
• Rated Voltage — 200 V DC rating for mid‑voltage power rails.
• Ripple Current Performance — 2.65 A at 120 Hz (low frequency) and 3.18 A at 10 kHz (high frequency) to support demanding AC ripple conditions.
• Leakage Current — 1.46 mA specified leakage, enabling predictable standby and charged‑state behavior.
• High‑Temperature Endurance — 2,000 hours life at 105°C (with DC bias plus rated ripple current), supporting sustained elevated temperature operation.
• Operating Temperature Range — −25°C to +105°C for broad environmental compatibility within the specified range.
• Mechanical Package — Snap‑in terminal, radial can package (φ35 × 40 mm), designed for secure mounting in power assemblies.
• Safety Vent — Series safety performance includes a pressure relief vent intended to operate without dangerous outcomes under abnormal conditions.
• Production‑Ready Packaging — Supplied in tray packing and listed as mass production to support volume assembly workflows.

Typical Applications

• General‑purpose power filtering — Bulk smoothing and decoupling on 200 V DC rails where 1200 µF capacitance and multi‑amp ripple handling are required.
• Ripple current mitigation — Use where sustained AC ripple must be absorbed at both low (120 Hz) and high (10 kHz) frequencies.
• High‑temperature power assemblies — Circuits operating up to 105°C that require capacitors with specified endurance under DC bias plus ripple.

Unique Advantages

• 200 V rating for mid‑voltage designs: Supports 200 V DC circuits without additional series stacking or complex arrangements.
• Dual‑band ripple capability: Rated ripple current at both 120 Hz and 10 kHz provides versatility across common power conversion topologies and switching frequencies.
• Long endurance at elevated temperature: 2,000 hours at 105°C under rated conditions offers predictable lifetime behavior in thermally stressed environments.
• Snap‑in mechanical retention: Radial snap‑in can (φ35 × 40 mm) enables robust panel or chassis mounting for higher current and vibration‑resistant assemblies.
• Predictable leakage performance: Specified leakage current of 1.46 mA supports accurate bias and hold‑up calculations in system designs.
• Production readiness: Tray packing and mass production status simplify procurement and assembly planning for volume manufacturing.
