LAS2W151MELA35ZB

The LAS2W151MELA35ZB is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power electronics requiring high-voltage smoothing and bulk capacitance. It combines a 150 µF capacitance with a 450 V rated voltage in a compact radial, can-type snap-in package.

Engineered for robust operation in demanding environments, this capacitor offers high ripple-current capability, a wide operating temperature range of −25°C to 105°C, and a 2000-hour endurance at 105°C—making it suitable for equipment exposed to fluctuating voltages and continuous power stress.

Key Features

• High Voltage Capacity — Rated at 450 V to support high-voltage DC bus and smoothing applications.
• 150 µF Capacitance with ±20% Tolerance — Provides stable bulk capacitance for energy storage and filtering; tolerance specified at 120 Hz, 20°C.
• Snap-In Radial Can Package — Durable snap-in terminals for secure board mounting and mechanical stability in power assemblies; package size φ25 × 35 mm (L: 3.5 × D: 2.5 cm).
• High Ripple Current — 880 mA at 120 Hz (low frequency) and 1.012 A at 10 kHz (high frequency) to handle continuous AC ripple on DC lines.
• Frequency Coefficient for Ripple Rating — Ripple current scales with frequency (e.g., coefficient 1.00 at 120 Hz, 1.15 at 10 kHz or higher), allowing designers to size thermal stress across operating frequencies.
• Low Loss and Leakage — Specified tangent of loss angle (tan δ) 0.20 max at 20°C, 120 Hz, and leakage current around 770 µA for predictable dissipation and standby behavior.
• 105°C Endurance — Rated endurance of 2000 hours at 105°C with defined limits for capacitance change, tan δ, and leakage current after test.
• Safety Features — Designed with features for abnormal voltage conditions and a pressure relief vent to mitigate risk during fault conditions.
• RoHS Compliant & Production-Ready — RoHS compliance and tray packing support volume manufacturing and assembly processes.

Typical Applications

• Power Supply Filtering — Bulk smoothing and ripple reduction on high-voltage DC rails in industrial and commercial power supplies.
• Power Converters and Inverters — DC bus smoothing and energy buffering in converter/inverter modules where high voltage and ripple capability are required.
• Industrial Equipment Subject to Voltage Fluctuations — Use in systems operating in environments with variable supply conditions thanks to enhanced safety features and voltage tolerance.
• Hold-up and Energy Storage — Short-term energy storage and hold-up capacitance for control circuits and power-management subsystems.

Unique Advantages

• High-Voltage, High-Capacitance Combination: 150 µF at 450 V provides substantial bulk energy in a compact footprint for demanding DC applications.
• Robust Ripple Handling: Specified ripple currents across low and high frequencies reduce thermal stress and extend operational stability in ripple-heavy environments.
• Compact Snap-In Form Factor: Radial snap-in can delivers secure mounting and space-efficient integration for power assemblies.
• Long Endurance at Elevated Temperature: 2000 hours at 105°C gives predictable lifecycle behavior for sustained high-temperature operation.
• Safety-Oriented Design: Improved safety against abnormal voltage and a pressure relief vent help manage fault conditions without hazardous outcomes.
• Manufacturing Ready: Tray packing and mass production status simplify procurement and assembly for volume designs.
