LAQ2P121MELZ25

The LAQ2P121MELZ25 is an aluminum electrolytic capacitor from Nichicon’s LAQ series featuring a snap-in terminal, radial can package designed for general-purpose use. It provides a 120 µF capacitance at a 220 V rating with polarized construction and is specified for operation across a wide temperature range.

Engineered for compact assemblies that require stable capacitance and high-temperature endurance, this part targets applications where snap-in mounting and a defined high-voltage rating are required.

Key Features

• Capacitance & Voltage — 120 µF nominal capacitance at a rated voltage of 220 V, with a tolerance of ±20% (at 120 Hz, 20°C).
• High-temperature Endurance — Rated for operation from -25°C to +105°C with an endurance specification of 2000 hours at 105°C under DC bias plus rated ripple current.
• Snap-in, Radial Can Package — Snap-in mounting type in a radial, can-style package for board-level installations that require secure mechanical retention.
• Ripple Current Performance — Specified ripple current capability of 600 mA at 120 Hz and 720 mA at 10 kHz for handling AC ripple in power circuits.
• Leakage & Dissipation — Leakage current defined by I ≤ 3√C (μA) after 5 minutes at 20°C; tangent of loss angle (tan δ) max 0.20 at 120 Hz, 20°C.
• Safety Design — Pressure relief vent feature for safe operation under abnormal voltage conditions as specified in the LAQ series documentation.

Typical Applications

• General-purpose electronic assemblies — Provides bulk capacitance for circuits that require a 120 µF, 220 V polarized snap-in capacitor for general-purpose smoothing and decoupling.
• Board-level power modules — Snap-in radial can package designed for secure insertion in PCB assemblies where a high-voltage electrolytic is needed.
• High-temperature environments — Suitable for systems that must operate up to 105°C with specified endurance (2000 hours at 105°C) under rated conditions.

Unique Advantages

• Clear electrical specification: 120 µF at 220 V gives designers a well-defined capacitance and voltage point for power and smoothing functions.
• Snap-in mechanical retention: Radial, snap-in can simplifies board assembly and secures the capacitor in place without additional hardware.
• High-temperature durability: Endurance rating of 2000 hours at 105°C provides data-backed reliability for elevated-temperature applications.
• Defined ripple handling: Rated ripple currents at both low and high frequencies (600 mA at 120 Hz and 720 mA at 10 kHz) help designers account for AC stresses.
• Measured leakage and loss metrics: Leakage current limit and tan δ ≤ 0.20 at 120 Hz enable predictable performance and easier system-level margining.
• Safety venting: Pressure relief vent reduces the risk of dangerous failure modes under abnormal voltage conditions, per series safety performance information.
