LHT2W471MELB55

The LHT2W471MELB55 is a Nichicon LHT series aluminum electrolytic capacitor in a snap-in terminal radial can. It delivers 470 µF at a 450 V rating with snap-in mounting and is specified for wide-temperature operation from −40°C to +125°C.

Designed for general-purpose applications that require high-voltage capacitance with extended high-temperature endurance, this part provides long life and measurable performance characteristics for power-related designs.

Key Features

• Capacitance & Voltage 470 µF rated capacitance at 450 V provides bulk energy storage for high-voltage circuits.
• Wide Temperature Range Specified to operate from −40°C to +125°C, supporting equipment that must function across extreme ambient conditions.
• High-Temperature Endurance Endurance rating of 3000 hours at 125°C (with DC bias plus rated ripple current) for sustained performance in elevated-temperature environments.
• Snap-in Terminal Package Radial, can-type snap-in mounting for secure chassis or PCB retention in demanding assemblies.
• Ripple Current & Frequency Response Rated ripple current 1.84 A at 120 Hz (at 125°C) and frequency coefficient data available for higher frequencies up to 50 kHz to support ripple-handling in power applications.
• Leakage, Loss and Tolerance Capacitance tolerance of ±20% (120 Hz, 20°C), leakage current ≤ 1.37 mA (per part table) and tan δ ≤ 0.20 at 120 Hz, 20°C for predictable electrical behavior.
• RoHS Compliant Compliant with the RoHS directive as noted in the product documentation.
• Compact Footprint Body dimensions φ30 × 55 mm (L: 5.5 × D: 3.0 cm) provide a high-voltage, high-capacitance solution in a relatively compact snap-in can.

Typical Applications

• General-purpose equipment For systems that require high-voltage bulk capacitance with wide temperature tolerance and long high-temperature endurance.
• Power filtering and smoothing Provides bulk energy storage and ripple handling at 450 V with rated ripple current defined at multiple frequencies for power circuits.
• High-temperature electronic assemblies Suitable where components are exposed to elevated ambient temperatures thanks to a −40°C to +125°C operating range and 3000-hour endurance at 125°C.

Unique Advantages

• High-voltage capacity: 450 V rating combined with 470 µF enables significant energy storage in high-voltage rail designs.
• Extended high-temperature life: 3000 hours endurance at 125°C ensures prolonged service in hot environments, reducing maintenance and replacement frequency.
• Predictable electrical performance: Specified leakage current, tan δ and ±20% tolerance provide measurable parameters for design margining and reliability calculations.
• Robust mounting: Snap-in radial can construction supports secure mechanical retention in chassis and power assemblies.
• Frequency-aware ripple handling: Rated ripple current at 120 Hz with frequency coefficients available for higher frequencies allows designers to size capacitors for the intended operating spectrum.
• Regulatory compliance: RoHS compliance simplifies integration into products targeting regulated markets.
