LLG2D102MELZ45

The LLG2D102MELZ45 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LLG series. It delivers 1 mF capacitance at a 200 V rating in a compact radial can with snap‑in mounting, designed to support equipment downsizing while maintaining required bulk energy storage and filtering.

Suited for general‑purpose power electronics, the LLG2D102MELZ45 combines a smaller case footprint (one rank smaller than LLS) with RoHS compliance to meet modern equipment and environmental requirements.

Key Features

• Capacitance & Rated Voltage — 1 mF nominal capacitance rated for 200 V, with a tolerance of ±20% (–20% to +20%), providing predictable bulk storage for smoothing and decoupling.
• Snap‑in Radial Package — Radial, can‑style snap‑in termination for reliable board retention and straightforward PCB mounting in through‑hole assemblies.
• Compact Size — One rank smaller case than the LLS series, offering space savings for equipment downsizing; physical footprint: L: 4.5 × D: 2.2 cm.
• Operating Range & Endurance — Rated for operation from –40 °C to +85 °C with a guaranteed endurance of 2000 hours at 85 °C under rated DC bias plus rated ripple current.
• Ripple Current Capability — Specified ripple handling of 2.55 A at 120 Hz and 3.825 A at 100 kHz, enabling effective smoothing of lower‑ and higher‑frequency ripple components.
• Polarized Design — Polarized electrolytic construction for bulk energy applications where polarity is defined.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863), meeting common environmental substance‑control requirements.

Typical Applications

• Power Supply Filtering: Bulk smoothing and ripple reduction in switch‑mode and linear power supplies where 1 mF at 200 V is required.
• Industrial Power Electronics: Energy storage and filtering in industrial control equipment seeking reduced board footprint through smaller case sizing.
• General Purpose Bulk Storage: Use as a polarized bulk capacitor in commercial and industrial assemblies requiring robust ripple handling and defined endurance.

Unique Advantages

• Space‑Saving Form Factor: One rank smaller case than LLS enables design compaction without changing capacitor family or basic performance characteristics.
• Strong Ripple Performance: Separate ripple ratings at 120 Hz and 100 kHz quantify capability across common operating frequencies, aiding thermal and lifetime planning.
• Clear Endurance Specification: 2000 hours at 85 °C under rated conditions gives a verifiable baseline for life‑cycle and reliability assessments.
• Snap‑In Mounting for Secure Assembly: Radial snap‑in terminals simplify through‑hole placement and mechanical retention for heavier components on PCBs.
• RoHS Compliance: Conforms to RoHS directives, supporting environmental regulatory requirements for commercial and industrial products.
