LGG2Z122MELB35

The LGG2Z122MELB35 is a snap‑in terminal aluminum electrolytic capacitor designed for general purpose applications where a compact, high‑voltage polarized capacitor is required. It delivers 1.2 mF capacitance at a rated voltage of 180 V in an ultra‑smaller‑sized case intended to support equipment downsizing.

Built for elevated operating temperatures up to 105°C and optimized for ripple handling, this capacitor is RoHS compliant and suited to designs that demand compact power storage, decoupling and smoothing in polarized circuits.

Key Features

• Electrical Performance — Rated capacitance 1.2 mF (1200 μF) with ±20% tolerance and a rated voltage of 180 V; polarized for DC energy storage and smoothing.
• High‑Temperature Endurance — Qualified for operation up to 105°C with an endurance specification of 2000 hours at 105°C under rated D.C. bias plus rated ripple current.
• Ripple Current Handling — Rated ripple current of 2.3 A at 120 Hz and 3.45 A at 100 kHz to support filtering and decoupling under AC ripple conditions.
• Low‑Temperature Stability — For the 160–250 V range (applicable to this part’s rated voltage), impedance ratio Z(–25°C)/Z(+20°C) is specified with a maximum of 4, supporting performance across the specified temperature range.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) max of 0.15 for 160–420 V range (measurement frequency 120 Hz at 20°C); leakage current follows I ≤ 3√CV (μA) after 5 minutes at 20°C.
• Package & Mounting — Radial can with snap‑in terminals provides a secure snap‑in mounting option for compact board layouts; part of the LGG series which is one rank smaller in case size versus LGN to support equipment downsizing.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Electronics — Energy storage and smoothing in polarized DC circuits where a compact, high‑voltage capacitor is required.
• Compact Power Supplies — Supports equipment downsizing by offering one rank smaller case size while retaining high voltage and capacitance.
• Power Filtering and Decoupling — Handles rated ripple currents at 120 Hz and 100 kHz for effective filtering of supply rails under AC ripple.

Unique Advantages

• Compact footprint for downsized equipment — The LGG series provides a smaller case size (one rank smaller than LGN) to help reduce enclosure and board area.
• High‑temperature reliability — Endurance qualified for 2000 hours at 105°C to support designs exposed to elevated operating temperatures.
• Robust ripple performance — Dual ripple ratings (2.3 A at 120 Hz and 3.45 A at 100 kHz) provide clear design targets for AC stress under different frequency conditions.
• Measurable electrical limits — Specified tan δ and leakage current behavior (I ≤ 3√CV) enable predictable performance and easier margining in designs.
• Secure snap‑in mounting — Radial snap‑in can improves mechanical retention for through‑hole power assemblies.
• RoHS compliance — Meets current RoHS directive requirements for lead‑restricted designs.
