LLG2D821MELA30

The LLG2D821MELA30 is an 820 µF, 200 V polarized aluminum electrolytic capacitor from Nichicon’s LLG series, featuring a snap‑in terminal can for robust board mounting. Designed as a one‑rank smaller case than the LLS series, it is intended to support equipment downsizing while delivering reliable bulk capacitance for general‑purpose circuits.

This component is RoHS compliant and specified for operation from −40 °C to +85 °C with a rated endurance of 2000 hours at 85 °C under DC bias plus rated ripple current, making it suitable for designs that require stable performance over prolonged elevated‑temperature operation.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance at a rated voltage of 200 V, providing substantial energy storage for general‑purpose applications.
• Snap‑in Terminal Package — Radial, can‑style snap‑in mounting for secure mechanical retention and straightforward PCB assembly.
• Compact LLG Series Size — One rank smaller case than the LLS series, suited for equipment downsizing while retaining required capacitance.
• Temperature and Endurance — Operating range −40 °C to +85 °C with a specified lifetime of 2000 hours at 85 °C under rated conditions.
• Ripple Current Capability — Rated ripple performance of 2.34 A at 120 Hz and 3.51 A at 100 kHz for handling AC components on DC rails.
• Polarized Aluminum Electrolytic — Designed as a polarized capacitor for DC applications that require high capacitance in a compact package.
• RoHS Compliance — Manufactured in accordance with RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power filtering — Provides bulk capacitance for smoothing and stabilization in DC power rails requiring 820 µF at 200 V.
• Space‑sensitive equipment — The LLG series’ reduced case size supports equipment downsizing where board space is limited.
• High‑ripple DC stages — Suitable where elevated ripple current handling is required, using the specified ripple ratings at 120 Hz and 100 kHz.

Unique Advantages

• Smaller case for downsized designs: One rank smaller than LLS offers equivalent capacitance with reduced footprint to aid compact product layouts.
• Robust board retention: Snap‑in terminal package provides secure mechanical mounting for assemblies subject to vibration or handling.
• Long endurance at elevated temperature: Specified 2000 hours at 85 °C under rated conditions supports reliable long‑term operation in warm environments.
• Measured ripple performance: Explicit ripple current ratings at 120 Hz and 100 kHz allow designers to match the part to expected AC stress on the capacitor.
• Regulatory compliance: RoHS conformity aligns with environmental requirements for commercial and industrial electronics.

Why Choose LLG2D821MELA30?

LLG2D821MELA30 addresses designs that need substantial bulk capacitance (820 µF) at a 200 V rating while minimizing enclosure and board space through the LLG series’ smaller case size. Its snap‑in mounting, defined ripple current ratings, and specified 2000‑hour endurance at 85 °C make it a practical choice for general‑purpose power stages where reliable DC energy storage and mechanical stability are required.

This capacitor is well suited to engineers and procurement teams working on compact power supplies and equipment that must meet RoHS requirements and maintain stable performance across a −40 °C to +85 °C operating range.
