LHT2W271MELB35

The LHT2W271MELB35 from Nichicon is an aluminum electrolytic capacitor in a snap‑in terminal, radial can package. It is rated 270 µF at 450 V and is part of the LHT series designed for wide temperature operation.

Engineered for general‑purpose equipment, this capacitor offers a wide operating range of −40 °C to +125 °C, RoHS compliance, and endurance characteristics tuned for sustained high‑temperature use.

Key Features

• Capacitance & Voltage: 270 µF rated at 450 V, providing a defined capacitance value for high‑voltage circuits.
• Snap‑In Package: Radial, can — snap‑in terminal mounting simplifies board assembly for through‑hole designs; physical size is φ30 × 35 mm (diameter × length).
• Wide Temperature Range & Endurance: Specified for −40 °C to +125 °C with an endurance rating of 3000 hours at 125 °C when subjected to DC bias plus rated ripple current.
• Ripple Current Performance: Rated ripple current of 1.27 A at 120 Hz (125 °C); frequency‑dependent behavior yields higher allowable ripple at elevated frequencies (example: 1.816 A at 50 kHz).
• Electrical Characteristics: Capacitance tolerance ±20% (120 Hz, 20 °C); tangent of loss angle (tan δ) ≤ 0.20 (120 Hz, 20 °C); leakage current specified as I ≤ 3√CV µA after 5 minutes at 20 °C.
• Environmental Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose equipment — used where reliable bulk capacitance and polarized snap‑in mounting are required in commercial and industrial assemblies.
• Power conversion and filtering — suitable for circuits that require defined ripple handling and capacitance stability over a wide temperature range.
• High‑temperature support equipment — intended for equipment expected to operate at elevated ambient temperatures up to 125 °C.

Unique Advantages

• High‑temperature capability: Rated to +125 °C with 3000 hours endurance at that temperature, enabling sustained operation in hot environments.
• Snap‑in mounting for robust mechanical retention: Radial, snap‑in terminals simplify assembly and secure the part in through‑hole boards.
• Defined ripple specifications: Rated ripple current and frequency coefficients provide measurable limits for thermal and ripple management in designs.
• Clear electrical limits: Specified tan δ, capacitance tolerance, and a leakage current formula (I ≤ 3√CV) make it straightforward to verify performance during design and qualification.
• Regulatory compliance: RoHS conformity reduces material compliance concerns for commercial and industrial supply chains.
