LAQ2P121MELZ25ZB

The LAQ2P121MELZ25ZB is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LAQ series. It provides 120 µF capacitance with a 220 V rated voltage in a compact φ22 × 25 mm radial can designed for general-purpose applications.

Key electrical characteristics include ±20% tolerance, low-frequency ripple capability, low leakage current, and a 2000-hour endurance rating at 105°C, making it suitable for designs that require a high-voltage electrolytic capacitor in a secure snap-in package.

Key Features

• Capacitance & Tolerance — 120 µF rated capacitance with ±20% tolerance (measured at 120 Hz, 20°C).
• Rated Voltage — 220 V working voltage suitable for higher-voltage general-purpose circuits.
• Snap-in Mounting — Radial, can-type snap-in terminal package (φ22 × 25 mm) for secure board retention and mechanical stability.
• Ripple Current Handling — 600 mA at 120 Hz (low frequency) and 720 mA at 10 kHz (high frequency), supporting AC ripple duties within rated limits.
• Low Leakage — Rated leakage current 480 µA (after rated voltage applied under standard conditions).
• High-Temperature Endurance — Endurance specified as 2000 hours at 105°C with defined limits for capacitance change, tan δ, and leakage current.
• Operating Temperature Range — -25°C to +105°C for deployment across a wide ambient range.
• Safety Design — Series safety performance includes a pressure relief vent to mitigate abnormal conditions.
• Loss Angle — Tangent of loss angle (tan δ) specified up to 0.20 max at 120 Hz, 20°C.

Typical Applications

• General-purpose 220 V systems — For circuits requiring a 120 µF, 220 V electrolytic capacitor in a snap-in form factor.
• Compact power assemblies — Where a φ22 × 25 mm radial can with snap-in terminals is needed to secure the capacitor mechanically.
• High-temperature environments — Applications that require components with endurance specified at 105°C (2000 h).

Unique Advantages

• High-voltage rating in a compact package: 220 V rating combined with a φ22 × 25 mm snap-in can provides a space-efficient solution for higher-voltage circuits.
• Dual-frequency ripple capability: Specified ripple currents at 120 Hz (600 mA) and 10 kHz (720 mA) support both low- and high-frequency ripple conditions.
• Long-term high-temperature endurance: 2000-hour endurance at 105°C provides defined performance stability under elevated temperature stress.
• Controlled leakage and dissipation: Rated leakage current of 480 µA and tan δ ≤ 0.20 (120 Hz, 20°C) enable predictable behavior in power designs.
• Secure mechanical mounting: Snap-in terminal radial can ensures reliable board retention for through-hole assemblies.
• Safety venting: Built-in pressure relief vent reduces risk under abnormal conditions in accordance with series safety performance specifications.
