LAQ2P151MELZ25ZB

The LAQ2P151MELZ25ZB is a 150 µF, 220 V aluminum electrolytic capacitor from Nichicon's LAQ series featuring a snap-in terminal package. It is a general-purpose, polarized snap-in can designed for applications that require compact energy storage with elevated temperature and ripple endurance.

Designed to withstand rated ripple current at 105°C for 2000 hours and to tolerate voltage fluctuation conditions, this part offers a compact footprint and enhanced safety measures for abnormally excessive voltage. The device is RoHS compliant.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with a 220 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High-temperature Endurance — Specified to endure rated ripple current plus D.C. bias for 2000 hours at 105°C, with defined limits for capacitance, tan δ and leakage after the test.
• Ripple Current Performance — Rated ripple current of 650 mA at 120 Hz and 780 mA at 10 kHz, enabling effective AC ripple handling in power circuits.
• Snap-in Radial Can Package — Snap-in terminal mounting for robust board retention and ease of installation in power assemblies; package form is radial can - snap-in.
• Temperature Range — Operates across −25°C to +105°C for demanding ambient conditions.
• Enhanced Safety — Series-level design improvements include features to mitigate hazards from abnormally excessive voltage and a pressure relief vent designed to operate without dangerous outcomes.
• Compact Size — Size dimensions: L: 2.5 × D: 2.2 cm, offering a smaller case compared with earlier LAK series parts while maintaining high ripple capability.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power filtering — Bulk energy storage and smoothing in power supply sections where a polarized snap-in capacitor is required within the 220 V range.
• Equipment operating in voltage-fluctuating areas — Intended for use in systems exposed to variable supply conditions, leveraging the series’ improved safety for abnormal voltage.
• High-temperature electronic assemblies — Suitable for circuits that must maintain performance up to 105°C with long-duration ripple endurance.

Unique Advantages

• Long ripple-endurance validated at 105°C — 2000-hour endurance under rated ripple current supports reliability in sustained high-temperature operation.
• High ripple current capability — 650 mA (120 Hz) and 780 mA (10 kHz) ratings reduce heating and improve performance in AC-rich power environments.
• Compact snap-in package — Smaller case size for space-constrained power assemblies while retaining robust board-mounted mechanical stability.
• Safety-focused design — Pressure relief vent and improved safeguards against excessive voltage help minimize risk under abnormal conditions.
• Straightforward integration — Polarized radial can snap-in format simplifies replacement and assembly in existing snap-in capacitor footprints.
• Regulatory compliance — RoHS conformity supports designs targeting restricted-substance compliance.
