Overview of LLG2D821MELZ40 – Snap‑in Aluminum Electrolytic Capacitor (820 µF, 200 V)

The LLG2D821MELZ40 is an aluminum electrolytic capacitor in a snap‑in terminal, smaller‑sized package designed for equipment downsizing. It provides 820 µF of capacitance at a 200 V rating with a radial, can-style snap‑in mounting for secure PCB installation.

Targeted for general‑purpose applications, this RoHS‑compliant capacitor combines compact packaging, defined ripple current capability, and proven endurance for designs that require reliable bulk capacitance in constrained spaces.

Key Features

  • Electrical Capacity & Voltage — 820 µF rated capacitance at 200 V provides substantial bulk capacitance for power systems that need high-voltage energy storage.
  • Compact Snap‑in Package — Radial, can-style snap‑in mounting with dimensions L: 4 cm × D: 2.2 cm; one rank smaller case size than LLS to support equipment downsizing.
  • Operating Temperature & Endurance — Specified for operation from −40 °C to +85 °C with an endurance rating of 2000 hours at 85 °C under DC bias plus rated ripple current.
  • Ripple Current Capability — Rated ripple currents of 2.49 A at 120 Hz and 3.735 A at 100 kHz, enabling effective handling of AC ripple in power applications.
  • Capacitance Tolerance & Polarization — ±20% tolerance at 120 Hz, 20 °C; polarized design for correct orientation in circuits.
  • Leakage and Loss Characteristics — Leakage current specified as I ≤ 3√CV (µA) after 5 minutes at 20 °C; tangent of loss angle (tan δ) ≤ 0.15 at 120 Hz and 20 °C for rated voltages in the 160–400 V range.
  • Low‑temperature Stability — Impedance stability at low temperature: Z(−25 °C)/Z(+20 °C) ≤ 4 for rated voltages in the 160–250 V range.
  • RoHS Compliant — Meets the RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances.

Typical Applications

  • General‑purpose power supplies — Bulk capacitance and ripple handling for compact power supply designs that require high-voltage smoothing in a reduced footprint.
  • Industrial equipment — Energy storage and DC link smoothing where long endurance at elevated temperatures (2000 hours at 85 °C) is required.
  • Commercial electronics — Suited for equipment downsizing projects that need a smaller case size without sacrificing capacitance or rated voltage.

Unique Advantages

  • Space-saving form factor: One rank smaller case than the LLS series helps reduce board area while retaining high capacitance.
  • High-voltage bulk capacitance: 820 µF at 200 V provides significant stored energy for DC link and smoothing uses in compact systems.
  • Defined ripple performance: Published ripple current ratings at 120 Hz and 100 kHz make it straightforward to size for application ripple conditions.
  • Proven endurance at elevated temperature: 2000 hours at 85 °C under DC bias plus rated ripple current supports reliable operation in warm environments.
  • Measured stability and loss limits: Specified tan δ and low‑temperature impedance ratios give clear electrical behavior for design verification.
  • RoHS compliance: Simplifies regulatory compliance for commercial and industrial products.
