LNT2W272MSEHBB

The LNT2W272MSEHBB is a screw-terminal aluminum electrolytic capacitor in Nichicon's LNT series, offering 2.7 mF (2700 µF) capacitance at a 450 V rating. It is a radial, can-style, polarized capacitor designed for general-purpose high-voltage applications that require significant bulk capacitance and high ripple-current capability.

Key value propositions include high ripple-current handling at both low and high frequencies, a wide operating temperature range up to 105°C, and a long load-life specification defined in the series datasheet.

Key Features

• Capacitance & Voltage — Rated at 2.7 mF (2700 µF) and 450 V for high-voltage bulk energy storage and filtering.
• High Ripple Current — Handles 14.5 A at 120 Hz (low frequency) and 20.3 A at 100 kHz (high frequency), supporting demanding ripple conditions.
• Temperature and Lifetime — Operating temperature range of −25 °C to +105 °C with series load-life guidance of 5,000 hours at +105 °C (series note: 2,000 hours applies for certain voltage ranges per datasheet).
• Screw Terminal Mounting — Radial can package with screw terminals for secure, low-impedance external connections and mechanical robustness.
• Polarized with Standard Tolerance — Polarized device with capacitance tolerance of −20% to +20% (±20% typical specification at 120 Hz, 20 °C).
• RoHS Compliant — Conforms to RoHS directive requirements as indicated for the LNT series.
• Compact Footprint — Package dimensions listed as L: 11 × D: 7.62 cm for board- and bracket-mount planning.

Typical Applications

• General-purpose high-voltage power systems — Provides bulk capacitance and energy buffering where a 450 V, 2700 µF polarized capacitor is required.
• High-voltage DC filtering and smoothing — High ripple-current ratings support attenuation of AC ripple in high-voltage DC circuits at both line-frequency and switching frequencies.
• Power conversion modules — Screw-terminal mounting and high-temperature endurance make it suitable for power modules and assemblies that require secure connections and sustained operation up to 105 °C.

Unique Advantages

• High ripple-current capability: Rated ripple currents of 14.5 A (120 Hz) and 20.3 A (100 kHz) reduce thermal stress under dynamic loading conditions.
• Long-term thermal endurance: Series endurance specified at 5,000 hours at +105 °C supports sustained high-temperature operation when subjected to rated ripple and DC bias.
• Screw-terminal robustness: Secure, low-impedance screw terminals simplify integration into power assemblies and make mechanical mounting straightforward.
• Large-capacitance, high-voltage solution: Combines 2700 µF with a 450 V rating to deliver substantial energy storage in a single component for space- and parts-count-sensitive designs.
• RoHS conformity: Meets RoHS requirements, aiding compliance for designs requiring restricted-substance adherence.
