LAQ2P681MELB40ZB

The LAQ2P681MELB40ZB is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power applications. It delivers 680 µF capacitance at a 220 V rating in a smaller-sized radial can with snap-in mounting.

Engineered for elevated thermal and electrical stress, this part supports operation from -25 °C to 105 °C, a 2000-hour endurance under rated ripple at 105 °C, and includes safety features for abnormal over-voltage conditions—making it suitable for equipment subject to voltage fluctuations.

Key Features

• Electrical specification: 680 µF nominal capacitance with ±20% tolerance; polarized design for DC bulk storage and smoothing.
• Rated voltage: 220 V DC rating suitable for mid-voltage power rail applications.
• Temperature and endurance: Operating range −25 °C to +105 °C with endurance validated at 2000 hours when D.C. bias plus rated ripple current is applied at 105 °C.
• Ripple current capability: 1.75 A at 120 Hz and 2.1 A at 10 kHz, supporting effective ripple handling across low and high frequencies.
• Package and mounting: Radial, can-type snap-in package with compact footprint (approx. L: 4 × D: 3 cm) for secure PCB installation.
• Safety features: Designed with improved safety for abnormally excessive voltage and a pressure relief vent that operates under abnormal conditions to prevent hazardous outcomes.
• Shelf and stability: Shelf-life and stability characteristics per series specification, including specified limits after storage at elevated temperature and post-voltage treatment.
• RoHS compliance: Series documentation indicates compliance with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply smoothing: Bulk energy storage and ripple smoothing on DC power rails in general-purpose equipment.
• Industrial equipment: Use in systems operating in voltage-fluctuating environments where enhanced safety and high-temperature endurance are required.
• Filtering for power electronics: Decoupling and filtering in mid-voltage assemblies that demand compact, high-capacitance solutions with reliable ripple handling.

Unique Advantages

• Compact, high-capacitance solution: 680 µF in a smaller case size enables space-efficient board designs without sacrificing capacitance.
• Validated high-temperature endurance: 2000 hours at 105 °C under rated ripple current provides measurable lifetime data for thermal-stressed designs.
• Broad ripple-performance range: Specified ripple-current ratings at both 120 Hz and 10 kHz support effective filtering across common power frequencies.
• Improved over-voltage safety: Series-level design improvements and a pressure relief vent reduce risk under abnormal voltage conditions.
• Secure snap-in mounting: Radial snap-in terminals simplify PCB assembly and provide robust mechanical retention for heavier bulk capacitors.
• Regulatory alignment: Documented RoHS directive compliance for markets requiring restricted-substance conformance.
