LASW6221MELC30

The LASW6221MELC30 is a snap‑in terminal aluminum electrolytic capacitor rated at 220 µF and 420 V. It is a compact, high‑voltage electrolytic designed for general‑purpose applications and for equipment operating in voltage‑fluctuating environments.

Engineered for elevated temperature and ripple conditions, this component offers 2000 hours endurance at 105°C under rated ripple current, improved safety features for abnormal overvoltage, and RoHS compliance.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 420 V and a tolerance of ±20% (120 Hz, 20°C).
• High‑temperature Endurance — Specified for 2000 hours at 105°C when D.C. bias plus rated ripple current is applied; capacitance change remains within ±20% after the endurance test.
• Ripple Current Capability — Rated ripple current values include 1 A at 120 Hz and 1.15 A at 10 kHz; frequency coefficients span from 0.88 at 50 Hz to 1.15 at 10 kHz or more.
• Safety Design — Improved safety features for abnormally excessive voltage and a pressure relief vent that operates without flames, ignition, or case dispersion under specified test conditions.
• Package & Mounting — Snap‑in terminal (radial can, snap‑in) package in a compact φ35 × 30 mm form factor (L: 3 cm × D: 3.5 cm); maximum seated height 1.181 inch.
• Operating Range — Suitable for operating temperatures from −25°C to +105°C.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Power Electronics — Bulk filtering and smoothing where a 420 V, 220 µF electrolytic is required for general‑purpose designs.
• Equipment in Fluctuating‑Voltage Environments — Designed for systems exposed to unstable supply conditions, leveraging improved safety features for abnormal overvoltage.
• High‑Temperature, High‑Ripple Circuits — Circuits that require sustained ripple handling at elevated temperatures benefit from the 2000‑hour endurance at 105°C under rated ripple current.

Unique Advantages

• Compact high‑voltage form factor: φ35 × 30 mm snap‑in package provides a smaller case size while supporting 420 V operation.
• Rated endurance at 105°C: 2000 hours of performance under rated ripple current enables reliable operation in hotter environments.
• Measured ripple capability across frequency: Specified ripple currents and frequency coefficients allow predictable performance from 50 Hz up to 10 kHz and above.
• Improved overvoltage safety: Enhanced safety features and a pressure relief vent reduce risk during abnormal excessive voltage events.
• RoHS compliant: Meets the RoHS directive requirements for controlled substances.
• Higher ripple current than LAQ: Designed to provide improved ripple handling compared to the LAQ series while offering smaller case sizes.
