LAK2D561MELZ45ZB

The LAK2D561MELZ45ZB is a snap‑in terminal aluminum electrolytic capacitor designed for high‑voltage, general‑purpose applications. It delivers 560 µF capacitance at a 200 V rating in a compact 22 mm × 45 mm radial can with polarized snap‑in mounting.

Engineered for environments with fluctuating line voltages, this capacitor provides extended voltage range support, withstands sustained ripple at elevated temperature, and includes safety measures to reduce hazards under abnormal voltage conditions.

Key Features

• Electrical Performance — 560 µF nominal capacitance, rated at 200 V DC with ±20% tolerance; polarized. Predictable leakage behavior defined by I ≤ 3√CV (µA) after 5 minutes at 20°C.
• Ripple Handling — Rated ripple current of 1.5 A at 120 Hz and 1.8 A at 10 kHz, enabling reliable smoothing and filtering under AC ripple conditions.
• Temperature & Endurance — Operates across −25°C to +105°C and is specified to withstand 2000 hours of rated ripple current at 105°C, meeting endurance criteria for capacitance change, tan δ and leakage current after the test.
• Safety & Reliability — Improved safety features for abnormally excessive voltage and a pressure‑relief vent designed to operate without flames or dangerous dispersion under normal test conditions.
• Package & Mounting — Radial, snap‑in can package (φ22 mm × 45 mm) for secure board mounting in demanding power assemblies.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulatory requirements for restricted substances.

Typical Applications

• Power supply smoothing and DC filtering — Bulk capacitance and rated ripple capability support energy storage and noise reduction in general‑purpose power supplies.
• Equipment in variable‑voltage environments — Designed for use where line voltages fluctuate; improved safety features address abnormal overvoltage events.
• Industrial and commercial power electronics — Snap‑in radial mounting and high‑temperature endurance make it suitable for robust assemblies requiring long life under thermal stress.

Unique Advantages

• High‑temperature endurance: Specified to withstand 2000 hours of rated ripple current at 105°C, providing predictable life in elevated temperature applications.
• Extended voltage range pedigree: Part of a series with 200 V (and extended 400 V / 420 V) availability, simplifying voltage scaling across designs.
• Measured ripple capability: Clear ripple current specifications at both 120 Hz and 10 kHz enable designers to select this capacitor with confidence for both low‑ and high‑frequency ripple conditions.
• Safety‑focused construction: Pressure‑relief vent and improved safety measures reduce risk during abnormal voltage events, improving system reliability.
• Compact snap‑in form factor: Radial snap‑in can (22 mm × 45 mm) offers a space-efficient solution for assemblies that require secure mechanical retention.
• Regulatory readiness: RoHS compliance supports deployment in markets requiring restricted‑substance conformity.
