LAS2W121MELZ35ZB

The LAS2W121MELZ35ZB is a Nichicon LAS series aluminum electrolytic capacitor in a snap‑in, radial can package. It delivers 120 µF capacitance at a 450 V rating with a compact φ22 × 35 mm case designed for secure PCB snap‑in mounting.

Designed for general‑purpose power applications and equipment exposed to voltage fluctuations, this part combines 105 °C endurance with high ripple current capability and safety features for abnormal voltage conditions. It is available in tray packing and is in mass production.

Key Features

• High voltage rating (450 V) — Rated for 450 V DC operation to support higher‑voltage power rails and converter stages.
• Capacitance and tolerance — 120 µF with ±20% tolerance (120 Hz, 20 °C) for bulk energy storage and smoothing.
• 105 °C endurance — Rated for 2000 hours at 105 °C under DC bias plus rated ripple current; capacitance change remains within ±20% and leakage remains at or below initial specified values after endurance testing.
• Snap‑in radial can package — φ22 × 35 mm canister with snap‑in terminals for reliable mechanical retention and straightforward PCB assembly; supplied in tray packing.
• Ripple current performance — Low‑frequency ripple current 770 mA at 120 Hz and high‑frequency ripple current 885.5 mA at 10 kHz for improved thermal handling under AC ripple stress.
• Low dissipation factor — tan δ (DF) 0.20 max at 120 Hz, 20 °C, for reduced losses in AC and switching environments.
• Leakage current — 690 µA initial leakage current rating for predictable standby and operating leakage behavior.
• Safety features for abnormal voltage — Designed with pressure relief vent performance to operate safely under abnormal voltage conditions without flame or hazardous dispersion.
• RoHS compliant — Meets RoHS requirements for restricted substances.

Typical Applications

• Power supplies and converters — Bulk filtering and energy storage on high‑voltage DC rails where 450 V rating and high ripple handling are required.
• Industrial power equipment — Support for equipment exposed to voltage fluctuations, leveraging 105 °C endurance and safety venting for robust operation.
• Energy conversion systems — Smoothing and decoupling in inverter, rectifier, and converter stages that demand high voltage capability and sustained ripple performance.

Unique Advantages

• Compact high‑voltage package: φ22 × 35 mm snap‑in can delivers 120 µF at 450 V in a small footprint to save board space.
• High temperature endurance: 2000 hours at 105 °C under rated conditions provides predictable lifetime behavior in elevated‑temperature environments.
• Robust ripple handling: Specified ripple currents at 120 Hz and 10 kHz allow designers to size capacitors with confidence for both low‑ and high‑frequency ripple stress.
• Predictable electrical characteristics: Low tan δ and defined leakage current support consistent loss and standby behavior in power designs.
• Safety‑oriented design: Pressure relief venting and abnormally excessive voltage protection reduce hazards under fault or fluctuation events.
• Regulatory compliance: RoHS compliance supports use in regions and products requiring restricted‑substance adherence.
