LASW6820MELA25ZB

The LASW6820MELA25ZB is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LAS series. It delivers 82 µF capacitance at a 420 V rating in a compact φ25 × 25 mm can designed for general‑purpose applications.

Engineered for reliability under elevated temperatures and varying voltages, this capacitor offers a wide operating range (−25°C to +105°C), high ripple current capability, and a 2000‑hour endurance rating at 105°C—making it suitable for equipment exposed to voltage fluctuations and continuous ripple loads.

Key Features

• Capacitance and Voltage — 82 µF rated capacitance at 420 V for higher‑voltage circuits requiring bulk capacitance in a compact package.
• High Temperature Endurance — Rated for 2000 hours at 105°C under DC bias plus rated ripple current, supporting long‑life operation in hot environments.
• High Ripple Current Capability — 640 mA at 120 Hz and 736 mA at 10 kHz frequency ratings to handle sustained AC ripple across a range of system frequencies.
• Electrical Stability — ±20% capacitance tolerance (120 Hz, 20°C) with tan δ (DF) ≤ 0.20 at 20°C, 120 Hz and leakage current specified at 550 µA.
• Safety and Abnormal Voltage Handling — Designed with improved safety features and a pressure relief vent to reduce risk under abnormally excessive voltage conditions.
• Package and Mounting — Snap‑in radial can package in a compact φ25 × 25 mm footprint; supplied in tray packing for mass production convenience.
• Environmental Compliance — RoHS‑compliant construction.

Typical Applications

• General Purpose Electronics — Use where a 82 µF, 420 V electrolytic is required and space is constrained, with operation from −25°C to +105°C.
• Equipment Subject to Voltage Fluctuations — The LAS series is described as ideally suited for equipment used in voltage‑fluctuating areas, offering improved safety features for abnormal voltages.
• High‑Ripple Circuits — Suitable for designs that must tolerate significant ripple currents up to 736 mA at 10 kHz or 640 mA at 120 Hz.

Unique Advantages

• Compact, High‑Voltage Solution — Delivers 82 µF at 420 V in a φ25 × 25 mm can, enabling space‑efficient high‑voltage designs.
• Long Life at Elevated Temperature — 2000 hours endurance at 105°C under rated conditions provides predictable aging and planning for maintenance cycles.
• Robust Ripple Handling — Frequency‑rated ripple current characteristics support a broad range of operating frequencies without compromising performance.
• Built‑In Safety Features — Pressure relief vent and improved abnormal‑voltage tolerance reduce risk during unexpected overvoltage events.
• Manufacturing‑Friendly Packaging — Tray packing and snap‑in terminals simplify handling and assembly for mass production runs.
• Measurable Electrical Characteristics — Specified tan δ, leakage current, and tolerance provide the data required for confident design integration and verification.
