LGW2D561MELZ35

The LGW2D561MELZ35 from Nichicon is a 560 µF, 200 V aluminum electrolytic capacitor in the LGW series, featuring a snap‑in radial can for secure board mounting. It is a high ripple‑current, 105°C rated component designed for general‑purpose power electronics where sustained ripple endurance and elevated operating temperature capability are required.

Key value comes from its combination of high ripple current capability, long endurance under rated ripple conditions, and RoHS compliance—making it suited for robust, high‑stress applications in industrial and commercial electronics.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance with a 200 V rated voltage and capacitance tolerance of ±20% (at 120 Hz, 20°C).
• High Ripple‑Current Capability — Rated ripple currents include 2.22 A at 120 Hz and 3.33 A at 50 kHz, supporting designs with significant AC ripple demands.
• Endurance at Elevated Temperature — Specified to withstand 3000 hours of rated ripple current at 105°C; after this test, capacitance change is within ±20% and leakage/tan δ remain within specified limits.
• Package & Mounting — Radial can with snap‑in terminals for reliable mechanical retention and straightforward PCB assembly; physical dimensions: L: 3.5 cm × D: 2.2 cm.
• Operating Temperature Range — Rated for operation from −40°C to +105°C, matching the series’ 105°C high‑temperature classification.
• Electrical Characteristics & Reliability — Leakage current defined by I ≤ 3√CV (µA) after 5 minutes at 20°C; tan δ maximum for 200–400 V category is 0.15 (measured at 120 Hz, 20°C).
• Frequency Ripple Coefficients — Frequency coefficients for the 200–250 V category include: 50 Hz = 0.81, 120 Hz = 1.00, and 50 kHz or more = 1.50 (useful for scaling rated ripple by operating frequency).
• RoHS Compliant — Manufactured in compliance with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk filtering and smoothing where sustained ripple handling and 105°C endurance help maintain performance under thermal stress.
• Power Converters and Inverters — Energy storage and ripple absorption in rectifier/filter stages that require high ripple‑current capability.
• General‑Purpose Electronic Equipment — Applicable wherever a robust, snap‑in aluminum electrolytic capacitor is needed for general power‑electronics functions.

Unique Advantages

• Long Ripple Endurance: Withstands 3000 hours of rated ripple current at 105°C, providing predictable life performance under continuous ripple stress.
• Frequency‑Scaled Ripple Ratings: Explicit ripple current values at 120 Hz and 50 kHz plus frequency coefficients allow designers to size capacitors accurately across operating frequencies.
• Secure Snap‑In Mounting: Radial, snap‑in can simplifies PCB retention and mechanical stability in assemblies.
• Wide Operating Temperature: −40°C to +105°C range supports use in thermally demanding environments within the specified rating.
• Clear Reliability Limits: Datasheet endurance and shelf‑life criteria (capacitance change, tan δ, leakage) give measurable pass/fail points for qualification and design validation.
• RoHS Compliance: Meets current RoHS directives for use in environmentally regulated markets.
