LLG2G221MELZ35

The LLG2G221MELZ35 is an aluminum electrolytic capacitor in Nichicon’s LLG series, featuring a snap‑in terminal configuration for robust board mounting. It provides a 220 µF capacitance at a 400 V rating in a compact 22 mm × 35 mm can, designed for general‑purpose power applications.

With a one‑rank smaller case size than the LLS series and RoHS compliance, this part is suited for equipment downsizing while delivering rated ripple performance and endurance at elevated temperatures.

Key Features

• Capacitance & Voltage: 220 µF rated at 400 V, providing bulk energy storage for high‑voltage circuits.
• Compact Snap‑In Package: Radial can with snap‑in terminals in a 22 mm (φ) × 35 mm (L) body (3.5 × 2.2 cm), one rank smaller than LLS for space‑constrained designs.
• Operating Temperature & Endurance: Rated for –25 °C to +85 °C with an endurance of 2000 hours at 85 °C under D.C. bias plus rated ripple current.
• Ripple Current Performance: Specified ripple capability of 1.4 A at 120 Hz and 2.002 A at 100 kHz to support steady filtering under ripple load.
• Leakage Current Specification: Leakage current meets I ≤ 3√CV (µA) after 5 minutes’ application of rated voltage at 20 °C, enabling predictable charge retention and recovery.
• AC Loss and Low‑Temperature Stability: Tan δ max. 0.15 (for 160–400 V) and an impedance ratio Z(–25 °C)/Z(+20 °C) of up to 8 at 400 V, allowing assessment of ESR/impedance behavior across temperature.
• Compliance: RoHS compliant (2011/65/EU, (EU)2015/863), meeting environmental substance restrictions.
• Polarized, General‑Purpose Design: Polarized electrolytic capacitor intended for broad general‑purpose power applications.

Typical Applications

• Compact power supplies: Bulk filtering and smoothing in space‑limited AC/DC and DC/DC power modules where a 400 V rating is required.
• Industrial and commercial equipment: General‑purpose decoupling and energy storage in downsized equipment designs.
• High‑voltage electronic assemblies: Polarized capacitor use in circuits that require a reliable 400 V electrolytic solution in a reduced footprint.

Unique Advantages

• Space‑saving form factor: One rank smaller than LLS and a compact 22 mm × 35 mm can make it easier to reduce overall equipment size.
• High voltage capability: 400 V rating supports high‑voltage rail filtering without upsizing the capacitor bank.
• Designed for elevated‑temperature endurance: 2000 hours at 85 °C under rated conditions provides predictable life performance for designs exposed to heat.
• Predictable ripple handling: Specified ripple currents at both 120 Hz and 100 kHz help designers size capacitors for real ripple workloads.
• Measurable electrical stability: Leakage current formula and tan δ/impedance limits provide clear parameters for reliability and low‑temperature behavior.
• Regulatory compliance: RoHS compliance supports use in regions requiring restricted‑substance adherence.
