LGJ2C271MELB15

The LGJ2C271MELB15 is an aluminum electrolytic, snap-in terminal capacitor from Nichicon’s LGJ series designed for general-purpose power applications. It delivers 270 µF at a 160 V rating in a compact, low-profile radial can (φ30 × 15 mm) tailored for assemblies that require robust ripple handling and elevated temperature endurance.

Key strengths include high ripple current capability at both low and high frequencies, low leakage characterized in the product data, and a rated operating range of −40 °C to 105 °C with a 2000 hour endurance at 105 °C, making it suitable where sustained thermal performance and reliable bulk capacitance are required.

Key Features

• Core Type Aluminum electrolytic capacitor; polarized design suited for DC bulk and filtering functions.
• Electrical Performance 270 µF capacitance with ±20% tolerance and 160 V rated voltage for medium-voltage DC applications.
• Ripple Current Capability Low-frequency ripple current 950 mA at 120 Hz and high-frequency ripple current 1.425 A at 50 kHz, supporting AC ripple and switching environments.
• Leakage Current Leakage current specified at 620 µA, providing a measurable characteristic for power-budget and standby calculations.
• Thermal and Endurance Operating temperature −40 °C to 105 °C with a rated life/endurance of 2000 hours at 105 °C.
• Package and Mounting Snap-in radial can package (φ30 × 15 mm) for secure chassis or PCB-mounted power assemblies; supplied in tray packing for production handling.
• Manufacturing Status Mass production availability from Nichicon’s LGJ series.

Typical Applications

• Power Supply Filtering Provides 270 µF bulk capacitance and measured ripple current ratings useful for smoothing and filtering in power supplies and intermediate DC rails.
• Switching Power Converters High-frequency ripple current rating (1.425 A at 50 kHz) supports use near switching elements where AC ripple is present.
• General Purpose Electronic Equipment Designed for general-purpose applications requiring polarized bulk capacitance in a low-profile, snap-in form factor and withstanding temperatures up to 105 °C.

Unique Advantages

• Compact low-profile form φ30 × 15 mm size minimizes vertical space while delivering substantial capacitance for dense power assemblies.
• Dual-frequency ripple handling Specified ripple current at both 120 Hz and 50 kHz lets designers quantify performance across rectified-line and switching domains.
• Elevated temperature endurance Rated for −40 °C to 105 °C with 2000 hours endurance at 105 °C to support sustained operation in warm environments.
• Tray packing for production Supplied in trays to streamline handling and placement in volume assembly processes.
• Clear electrical specifications Defined leakage current (620 µA) and tolerance (±20%) simplify design verification and reliability calculations.
