LGU2C821MELB

The LGU2C821MELB is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LGU series designed for general‑purpose applications. It delivers 820 µF capacitance at a 160 V rating in a radial, snap‑in can package with a compact φ30×30L footprint.

Built for sustained operation in elevated temperatures, this part is specified for –40°C to 105°C and an endurance of 3000 hours at 105°C, with rated ripple current performance characterized across low and high frequencies.

Key Features

• Capacitance & Tolerance — 820 µF nominal with ±20% tolerance (measured at 120 Hz, 20°C), providing predictable bulk energy storage and decoupling for designs requiring this capacitance/voltage point.
• Rated Voltage — 160 V DC rating suitable for higher‑voltage general‑purpose circuits.
• Snap‑In Radial Can Package — Snap‑in terminals in a radial can (φ30×30L) for secure mechanical mounting and efficient PCB assembly using tray packing.
• High Ripple Current Capability — Rated ripple current of 2.04 A at 120 Hz and 3.06 A at 50 kHz, with frequency coefficients for the 160–250 V range (e.g., 0.81 at 50 Hz, 0.85 at 60 Hz, 1.00 at 120 Hz, up to 1.50 at 50 kHz or more).
• Low Leakage — Leakage current specified at 1080 µA (measured after rated voltage application at 20°C), supporting stable performance after power application.
• Endurance at Elevated Temperature — Withstands application of rated ripple current plus DC bias for 3000 hours at 105°C while meeting specified capacitance, tan δ, and leakage limits.
• Loss Tangent — tan δ (max.) 0.15 at 120 Hz, 20°C for the 160–420 V range, enabling predictable dissipation characteristics at operating frequency.
• RoHS Compliant — Conforms to RoHS requirements for environmental compliance.

Typical Applications

• General Purpose — High‑Voltage Circuits: Suited to general‑purpose circuits that require an 820 µF capacitor at a 160 V rating.
• General Purpose — Elevated Temperature Environments: Appropriate where operation across –40°C to 105°C and long endurance at 105°C are required.
• General Purpose — Snap‑In Mounted Systems: Designed for installations that benefit from a radial, snap‑in can package with a φ30×30L footprint and tray packing for volume assembly.

Unique Advantages

• High‑Voltage, High‑Capacitance Combination: 820 µF at 160 V provides substantial energy storage in a single component, reducing the need for parallel devices when that capacitance/voltage point is required.
• Documented Ripple Performance Across Frequency: Rated ripple currents at 120 Hz and 50 kHz, plus frequency coefficients for the 160–250 V range, let designers predict heating and derating across operating frequencies.
• Long Endurance at 105°C: Specified 3000 hours endurance under rated ripple and DC bias supports reliable long‑term operation in warm environments.
• Predictable Loss Characteristics: Low tan δ (max. 0.15 at 120 Hz) helps control dissipation and thermal behavior in AC‑excited circuits.
• Robust Mechanical Mounting: Snap‑in terminals in a radial can package offer a secure, assembly‑friendly solution for PCB installations.
• Regulatory Compliance: RoHS compliance helps streamline environmental and manufacturing requirements.
