LASW6121MELA30

The LASW6121MELA30 is an aluminum electrolytic capacitor in a snap‑in terminal can, rated 120 µF at 420 V with ±20% tolerance. Designed for general‑purpose power applications, it offers high ripple handling and extended endurance for equipment operating in voltage‑fluctuating environments.

Built to operate from −25°C to 105°C and specified for 2000 hours at 105°C under rated ripple conditions, this Nichicon LAS series part targets power supplies and other systems requiring reliable high‑voltage bulk capacitance in a compact snap‑in package.

Key Features

• Capacitance & Voltage — 120 µF capacitance at a 420 V rated voltage with ±20% tolerance (120 Hz, 20°C).
• High operating temperature and endurance — Rated for operation from −25°C to 105°C with endurance of 2000 hours at 105°C when subjected to DC bias plus rated ripple current.
• Snap‑in terminal package — Radial, can-type snap‑in mounting for secure, board‑level installation and tray packing for mass production supply.
• Ripple current capability — 750 mA at 120 Hz (low frequency) and 862.5 mA at 10 kHz (high frequency), with frequency coefficients provided for other frequencies.
• Low leakage and loss — Specified leakage current of 670 µA and tangent of loss angle (tan δ) ≤ 0.20 at 120 Hz, 20°C.
• Safety design — Built‑in pressure relief vent and improved safety features for abnormally excessive voltage conditions as defined for the LAS series.
• Compact dimensions — Size approximately φ25 × 30L (L: 3 cm × D: 2.5 cm), suitable where smaller case size is required.
• RoHS compliant — Meets RoHS directive requirements.

Typical Applications

• General power supplies — Bulk smoothing and energy storage in high‑voltage DC power supplies operating up to 420 V and up to 105°C ambient.
• Equipment in fluctuating voltage environments — Suited to systems exposed to variable input voltages where improved safety and endurance are required.
• High‑frequency filter stages — Effective where elevated ripple current at higher frequencies (10 kHz) is present, supported by a specified high‑frequency ripple current rating.

Unique Advantages

• High‑voltage capability: 420 V rating enables use in higher DC bus and industrial applications without series stacking.
• Long endurance at elevated temperature: 2000 hours at 105°C under rated ripple provides predictable lifetime performance in hot operating environments.
• Strong ripple handling across frequencies: Separate low‑ and high‑frequency ripple current specs (750 mA at 120 Hz, 862.5 mA at 10 kHz) help designers match component selection to operating conditions.
• Compact, board‑friendly package: Snap‑in can format with smaller case size supports space‑constrained power assemblies and streamlined assembly processes.
• Controlled electrical characteristics: Low specified leakage current (670 µA) and tan δ ≤ 0.20 aid predictable performance and thermal management.
• Safety features: Pressure relief vent and design provisions for abnormal voltage help reduce risk in voltage‑fluctuating applications.
