LAQ2D181MELZ25ZB

The LAQ2D181MELZ25ZB is a Nichicon LAQ series aluminum electrolytic capacitor in a snap-in terminal radial can. It delivers 180 µF of bulk capacitance at a rated voltage of 200 V with a compact φ22 × 25 mm footprint and snap-in mounting for secure mechanical and electrical installation.

Designed for general-purpose electronic equipment, this part offers long-term endurance at elevated temperature and defined ripple handling across low and high frequencies, providing reliable bulk energy storage and smoothing where a 200 V capacitor is required.

Key Features

• Capacitance & Voltage — 180 µF rated capacitance at 200 V with ±20% tolerance (120 Hz, 20°C).
• Package & Mounting — Snap-in terminal, radial can package sized φ22 × 25 mm (L: 25 mm, D: 22 mm) for chassis or PCB modules requiring secure mounting.
• Ripple Current (Low & High Frequency) — Rated ripple handling of 700 mA at 120 Hz and 840 mA at 10 kHz to support circuits with moderate AC ripple stress.
• Low Leakage — Specified leakage current of 0.56 mA after standard application of rated voltage.
• High-Temperature Endurance — Specified life of 2000 hours at 105°C under D.C. bias plus rated ripple current; after the endurance test the capacitor meets defined limits for capacitance change, tan δ and leakage current.
• Operating Temperature Range — Rated for operation from −25°C to +105°C.
• Safety Vent — Pressure relief vent designed to operate under abnormal conditions without flames or dangerous dispersion of pieces.
• Smaller-sized Construction — Part of the LAQ series optimized for a smaller footprint while maintaining endurance and ripple capability.

Typical Applications

• General-purpose electronics — Bulk capacitance and energy storage for assemblies that require 180 µF at 200 V with defined ripple handling and long-term endurance.
• Power modules and chassis-mounted assemblies — Snap-in radial can (φ22 × 25 mm) provides secure mounting for modules where mechanical stability is important.
• High-ripple circuits — Suitable for circuits with moderate ripple stress, supporting 700 mA at 120 Hz and 840 mA at 10 kHz.
• Elevated-temperature environments — Rated life of 2000 hours at 105°C under DC bias plus rated ripple current for designs requiring sustained operation at higher ambient temperatures.

Unique Advantages

• High-voltage bulk capacitance: 180 µF at 200 V provides substantial stored energy in a compact snap-in can.
• Defined ripple performance: Dual ripple ratings (700 mA @ 120 Hz, 840 mA @ 10 kHz) enable predictable thermal and electrical behavior across common ripple frequencies.
• Long endurance at elevated temperature: 2000 hours at 105°C under D.C. bias plus rated ripple current supports designs requiring extended life under stress.
• Low leakage: 0.56 mA leakage current supports designs sensitive to standby current and long-term retention of charge.
• Secure mechanical mounting: Snap-in terminal and radial can package simplify installation in chassis or module assemblies.
• Safety-aware design: Pressure relief vent reduces the risk of hazardous failure modes during abnormal conditions.
