LGJ2D221MELB15

The LGJ2D221MELB15 from Nichicon is a snap-in terminal type aluminum electrolytic capacitor in the LGJ series, sized for low-profile installations. It provides 220 µF capacitance at 200 V with a compact φ30 × 15 mm can and is intended for general-purpose power electronic designs.

Designed for 105°C operation and 2000 hours endurance at that temperature, this capacitor delivers high ripple-current capability and controlled leakage for applications that require robust performance in elevated temperature environments.

Key Features

• Capacitance and Voltage 220 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance, providing predictable bulk capacitance for power circuits.
• High Temperature Endurance Qualified for operation from −40°C to +105°C with a rated life of 2000 hours at 105°C, supporting long-term operation in hot environments.
• High Ripple Current Handling Supports 900 mA ripple current at 120 Hz and 1.35 A at 50 kHz, enabling effective smoothing and decoupling in high-stress power applications.
• Controlled Leakage Specified leakage current of 620 µA, allowing designers to budget for standby and quiescent currents accurately.
• Snap-In Radial Can Package Snap-in terminal, radial can construction (φ30 × 15 mm) for secure chassis mounting and easy insertion into power assemblies.
• Series Proven Characteristics Part of Nichicon’s LGJ series which documents performance characteristics such as tan δ limits, impedance ratios, and ripple-frequency coefficients applicable to 200–450 V parts in the series.

Typical Applications

• General-purpose power electronics Suited for circuits that require a 200 V, 220 µF snap-in aluminum electrolytic capacitor with high ripple capability and 105°C endurance.
• Power supply filter stages Used where bulk capacitance and high ripple-current handling are needed to smooth and stabilize DC rails at elevated temperatures.
• Industrial control and power modules Applicable in industrial equipment designs that demand robust electrolytic capacitance in a compact snap-in package.
• Energy conversion circuits Appropriate for converters and related power circuitry that benefit from controlled leakage and sustained performance at up to 105°C.

Unique Advantages

• Compact low-profile form factor: The φ30 × 15 mm snap-in can provides substantial capacitance in a space-efficient package for chassis-mounted designs.
• High-temperature robustness: Rated for −40°C to +105°C and 2000 hours life at 105°C, offering predictable performance in thermally demanding applications.
• Designed for high ripple environments: 900 mA at 120 Hz and 1.35 A at 50 kHz ripple ratings let you manage ESR heating and ripple-induced stress effectively.
• Measurable leakage behavior: Specified leakage current (620 µA) and series leakage formulas enable accurate system-level power budgeting.
• Reliable snap-in mounting: Snap-in radial can package simplifies mechanical retention and electrical connection in power assemblies.
