LHT2W221MELB30

The LHT2W221MELB30 is an aluminum electrolytic capacitor from Nichicon's LHT series featuring a snap-in terminal radial can construction. It delivers 220 µF capacitance at a 450 V rated voltage with ±20% tolerance.

Designed for general-purpose equipment that requires wide temperature capability and long-term endurance, this component supports an operating temperature range of −40°C to +125°C and an endurance of 3000 hours at 125°C. Key electrical characteristics include a rated ripple current of 1.12 A at 120 Hz, a low tangent of loss angle (tanδ ≤ 0.20 at 120 Hz, 20°C), and a leakage current of 0.94 mA.

Key Features

• Voltage & Capacitance  220 µF rated capacitance with a 450 V nominal voltage and ±20% tolerance at 120 Hz, 20°C.
• Wide Temperature Range & Endurance  Operates from −40°C to +125°C with an endurance rating of 3000 hours at 125°C under rated conditions.
• Ripple Current Performance  Rated ripple current of 1.12 A at 120 Hz and 1.602 A at 50 kHz supports significant AC stress handling.
• Low Losses & Leakage  Tangent of loss angle (tanδ) is 0.20 max at 120 Hz, 20°C, and leakage current is specified at 0.94 mA for the 220 µF, 450 V size.
• Package & Mounting  Compact 30 × 30 mm (φ30 × L30 mm) radial can with snap-in terminals for secure PCB mounting.
• Regulatory Compliance  Compliant with the RoHS Directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-Purpose Power Equipment  Suitable where a high-voltage, high-capacitance snap-in capacitor is required for general-purpose designs.
• High-Temperature Equipment  Appropriate for equipment that requires stable capacitor operation across −40°C to +125°C and extended endurance at elevated temperatures.
• Power Systems with Elevated Ripple Stress  Useful in designs that demand rated ripple-current capability (1.12 A at 120 Hz and higher-frequency performance up to 1.602 A at 50 kHz).

Unique Advantages

• High Voltage Capability:  450 V rating enables use in higher-voltage power applications without changing component family.
• Extended High-Temperature Endurance:  3000 hours at 125°C provides predictable lifetime performance in hot operating environments.
• Measured Ripple Performance:  Specified ripple currents at 120 Hz and higher frequencies allow designers to quantify AC stress capacity for reliable operation.
• Controlled Loss and Leakage:  tanδ ≤ 0.20 and specified leakage current (0.94 mA) support energy-efficiency and predictable electrical behavior.
• Compact Snap-In Form Factor:  φ30 × 30 mm radial can with snap-in terminals combines a small footprint with robust mechanical retention on the PCB.
• RoHS Compliance:  Meets RoHS Directive (2011/65/EU, (EU)2015/863) requirements for environmentally regulated designs.
