LGU2F221MELA

The LGU2F221MELA is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGU series, specified at 220 µF and 315 V with ±20% tolerance. It is a radial, can-style snap-in component designed for general-purpose applications that require high-voltage capacitance with extended endurance.

Key value propositions include a 105°C rated operating temperature, 3000 hours endurance at 105°C, low leakage current, and ripple performance characterized at both low and high frequencies—features that support reliable long-term operation in demanding power circuits.

Key Features

• Electrical Performance — 220 µF capacitance at a 315 V rated voltage with ±20% tolerance, providing stable energy storage for high-voltage circuits.
• Loss and Leakage — tanδ ≤ 0.15 (measured at 20°C, 120 Hz) and leakage current of 780 µA, enabling predictable loss characteristics and low standby current.
• Ripple Current Capability — Rated ripple current of 1.04 A at 120 Hz and 1.487 A at 50 kHz, supporting AC ripple handling across low and high frequencies.
• High-Temperature Endurance — Designed for 3000 hours of operation at 105°C under rated ripple and DC bias, meeting long-life endurance requirements.
• Thermal Range — Operating temperature range from –25°C to 105°C, suitable for elevated-temperature environments within the specified range.
• Package and Mounting — Radial, can-style snap-in construction (φ25 × 30L) for secure PCB mounting and tray packing for production handling.
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose power circuits — Provides bulk capacitance and ripple smoothing in circuits requiring 315 V rated voltage and high-temperature endurance.
• Industrial equipment — Suitable where long-life, high-voltage electrolytic capacitance is required within the –25°C to 105°C operating range.
• Commercial power modules — Snap-in mounting and tray packing support production assembly of radial can capacitors for general-purpose commercial designs.

Unique Advantages

• High-voltage rating (315 V): Enables use in higher-voltage general-purpose designs without the need for series stacking of lower-voltage parts.
• Extended endurance at 105°C: 3000 hours rated life under specified conditions supports long-term reliability in elevated-temperature environments.
• Broad ripple performance: Specified ripple current at both 120 Hz (1.04 A) and 50 kHz (1.487 A) gives designers quantified AC handling across frequency ranges.
• Low leakage current: 780 µA leakage helps minimize standby losses and simplifies bias management in power circuits.
• Snap-in radial package: Robust PCB mounting and tray packing facilitate automated assembly and secure mechanical retention.
• RoHS compliant: Meets regulatory requirements for lead-free manufacturing environments.
