LASW6151MELA35ZB

The LASW6151MELA35ZB is an aluminum electrolytic, snap-in terminal capacitor designed for general-purpose applications that require a 420 V rated voltage and 150 µF capacitance. It combines a compact radial can snap-in package with a high operating temperature rating and enhanced safety features for use in environments with voltage fluctuations.

Key value propositions include high ripple-current capability, endurance at elevated temperature, and improved safety under abnormal voltage conditions—making it suitable for equipment operating up to 105°C and adhering to RoHS requirements.

Key Features

• Rated Performance — 150 µF capacitance with ±20% tolerance and a 420 V rated voltage provide a defined energy-storage solution for high-voltage designs.
• High Temperature Endurance — Designed to withstand 2000 hours of rated ripple current at 105°C; endurance limits for capacitance, tan δ and leakage current are specified after this test.
• Snap-in, Radial Can Package — Snap-in terminal mounting offers secure board installation in a compact can-style package (L: 3.5 × D: 2.5 cm).
• High Ripple Current — Rated ripple current of 820 mA at 120 Hz and 943 mA at 10 kHz supports demanding AC ripple conditions across common frequencies.
• Permissible Abnormal Voltage & Safety Vent — Improved safety features for abnormally excessive voltage with a pressure relief vent designed to operate without flames or dispersion of parts under test conditions.
• Wide Operating Range — Operating temperature from −25°C to +105°C accommodates a broad set of environmental conditions.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose industrial equipment — Suitable for general-purpose designs requiring a 420 V, 150 µF electrolytic capacitor.
• Equipment operating in fluctuating-voltage environments — Improved safety performance and permissible abnormal voltage characteristics make it well suited for devices subject to voltage variations.
• High-temperature systems — Endurance at 105°C for 2000 hours makes it appropriate for applications with sustained elevated temperatures.

Unique Advantages

• Defined high-voltage capability: 420 V rated voltage with a specified 150 µF capacitance gives predictable energy storage for high-voltage circuits.
• Long high-temperature endurance: Qualification at 2000 hours at 105°C under rated ripple current supports designs that require prolonged thermal reliability.
• Robust ripple handling: Rated ripple currents of 820 mA (120 Hz) and 943 mA (10 kHz) provide clear margins for AC ripple management across frequencies.
• Enhanced safety under abnormal voltage: Pressure relief vent and defined safety test conditions reduce risk in scenarios with excessive voltage exposure.
• Space-efficient snap-in form factor: Smaller case sizes relative to LAQ series while offering higher ripple current, enabling more compact board layouts.
• RoHS compliance: Meets applicable RoHS requirements for environmentally restricted substances.
