LGR2E821MELC40

The LGR2E821MELC40 is an aluminum electrolytic capacitor in a snap‑in radial can package, offering 820 µF capacitance at a 250 V rating. It is designed for general‑purpose applications that require high voltage capability, elevated temperature operation, and long life assurance.

Key architectural attributes include snap‑in terminals for robust board retention, polarized construction, and a long‑life specification of 10,000 hours at 105°C for sustained ripple current operation.

Key Features

• Capacitance & Voltage: 820 µF rated capacitance at 250 V — provides substantial bulk energy storage for high‑voltage designs.
• High‑temperature Long Life: Rated for operation from −40°C to 105°C with a rated lifetime of 10,000 hours at 105°C under rated ripple and DC bias.
• Snap‑in Radial Package: Snap‑in terminal type and radial can package for secure mounting and mechanical stability in panel and PCB assemblies.
• Ripple Current Capability: Specified ripple current of 2 A at 120 Hz (low frequency) and 3 A at 50 kHz (high frequency); frequency coefficients for 200/250 V are provided so designers can scale ripple capability across frequencies.
• Electrical Stability: Leakage current defined as I ≤ 3√(C·V) µA after 5 minutes at 20°C; tan δ maximum of 0.15 for 200–400 V ratings.
• Tolerance & Polarization: Capacitance tolerance ±20% and polarized construction for DC bulk filtering applications.
• RoHS Compliant: Manufactured to meet RoHS requirements.

Typical Applications

• General‑purpose power systems — Bulk energy storage and smoothing in general‑purpose designs requiring 820 µF at 250 V and long life at elevated temperature.
• High‑temperature electronic equipment — Suitable where continuous operation up to 105°C and a 10,000‑hour endurance at that temperature are required.
• High‑voltage filtering — 250 V rating and defined ripple current performance (including frequency coefficients) support AC ripple and filtering tasks across a range of frequencies.

Unique Advantages

• Long life assurance: 10,000 hours endurance at 105°C under rated ripple and DC bias provides predictable long‑term performance.
• High temperature capability: −40°C to 105°C operating range supports elevated‑temperature deployments without derating beyond specified limits.
• Designed for ripple stress: Rated ripple current and published frequency coefficients (50 Hz to ≥50 kHz for 200/250 V) let engineers size the capacitor precisely for expected operating frequencies.
• Predictable leakage behavior: Leakage current defined by I ≤ 3√(C·V) µA after 5 minutes at 20°C enables reliable system power budgeting and safety margining.
• Robust mounting: Snap‑in radial can package provides mechanical retention suitable for through‑hole assembly in demanding assemblies.
• RoHS compliant manufacturing: Meets environmental directives for restricted substances.
