LAQ2P102MELC45ZB

The LAQ2P102MELC45ZB is a Nichicon LAQ series snap-in aluminum electrolytic capacitor rated at 1000 µF and 220 V. It combines a compact radial can snap-in package (φ35 × 45 mm) with specifications tuned for general-purpose power-electronic applications.

Designed for systems that require high ripple handling and long-term stability, this capacitor offers defined ripple current capability, controlled leakage, and endurance for elevated-temperature operation up to 105°C.

Key Features

• Capacitance & Voltage — 1000 µF nominal capacitance at a rated voltage of 220 V for bulk energy storage and smoothing.
• Tolerance — ±20% capacitance tolerance (measured at 120 Hz, 20°C), providing predictable performance for design margins.
• High Ripple Current — Rated ripple current of 2400 mA at 120 Hz (low frequency) and 2880 mA at 10 kHz (high frequency) to support AC ripple in power circuits.
• Leakage Current — Typical leakage current specified at 1400 µA; series specification also follows I ≤ 3√C µA after rated voltage application.
• Operating Temperature & Endurance — Specified operating range from −25°C to +105°C with an endurance rating of 2000 hours at 105°C (capacitance change within ±20%, tan δ ≤ 200% of initial, leakage ≤ initial).
• Package & Mounting — Radial, can-type snap-in terminal for robust mechanical retention and straightforward assembly in tray packing for mass production.
• Electrical Characteristics — Tangent of loss angle (tan δ) ≤ 0.20 at 120 Hz, and low-temperature impedance stability data available for design verification.
• Safety Design — Includes a pressure-relief vent to mitigate abnormal conditions without generating flames or dispersing case fragments.

Typical Applications

• Power Supplies — Bulk smoothing and filtering in medium-voltage DC rails where 220 V rating and high ripple current capability are required.
• Industrial Power Electronics — Energy buffering and decoupling in converters and inverters operating at elevated temperatures up to 105°C.
• UPS and Energy Storage Subsystems — Bulk capacitance for short-term energy hold-up and ripple attenuation in backup and conditioning circuits.

Unique Advantages

• High ripple tolerance: 2400 mA at 120 Hz and 2880 mA at 10 kHz support demanding AC ripple conditions without compromising life.
• Extended high-temperature endurance: 2000 hours at 105°C with specified limits on capacitance change, tan δ, and leakage ensures predictable aging in hot environments.
• Compact snap-in form factor: φ35 × 45 mm radial can with snap-in terminals offers space-efficient bulk capacitance and secure PCB mounting for production assemblies.
• Measured electrical stability: Specified tan δ and low-temperature impedance characteristics allow engineers to evaluate loss and impedance across operating conditions.
• Safety-focused construction: Pressure-relief venting reduces risk in abnormal voltage conditions while maintaining safe failure modes.
