LNY2V272MSEF

The LNY2V272MSEF is a screw-terminal aluminum electrolytic capacitor offering 2.7 mF (2700 µF) capacitance at a rated voltage of 350 V. It is a radial can with screw terminals and designed to support equipment downsizing while delivering robust power-filtering performance.

Targeted at general-purpose power applications, this capacitor provides long-term operation at elevated temperatures with a specified load life under ripple-current stress, making it suitable for power supplies and industrial electronics where reliable bulk capacitance and high ripple capability are required.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) rated at 350 V, with a tolerance of ±20% (120 Hz, 20°C).
• High ripple capability — Rated ripple current of 12.2 A at 120 Hz and 17.08 A at 10 kHz supports heavy AC ripple conditions in power circuits.
• Thermal endurance — Load life of 2000 hours with rated ripple current applied at 85°C, supporting sustained operation under elevated temperatures.
• Wide operating temperature — Specified for –40°C to +85°C operation.
• Robust insulation and voltage withstand — Insulation resistance more than 100 MΩ at DC 500 V between terminal and bracket; no abnormality under AC 2500 V for 1 minute between terminal and bracket.
• Mounting and package — Radial can with screw terminals (M5 bolt nominal for φ51), designed for secure mechanical and electrical connection; dimensions: φ51 × 90 L (L: 9 × D: 5.1 cm).
• Leakage current specification — After 5 minutes at rated voltage, leakage current is ≤ 3√(C·V) µA or 5 mA, whichever is smaller (at 20°C).
• RoHS compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial power supplies — Bulk energy storage and smoothing for switch-mode and linear power supplies where high ripple current handling is required.
• Motor drives and inverters — DC link and energy buffer capacitor for drives and power conversion systems that demand high capacitance at elevated voltage.
• Server and telecom power racks — Bulk filtering and hold-up capacitance in rack-mounted power modules benefiting from screw-terminal mounting for secure connections.

Unique Advantages

• Compact high-capacitance design — 2700 µF in a φ51 × 90 L package supports equipment downsizing without sacrificing bulk capacitance.
• High ripple tolerance — Specified ripple current values at both low and high frequencies let designers size capacitors confidently for real-world AC ripple environments.
• Proven thermal endurance — 2000 hours of rated-load life at 85°C demonstrates durability for continuous elevated-temperature operation.
• Secure screw-terminal mounting — M5 screw terminals and compatible bracket dimensions simplify installation and provide reliable electrical/ mechanical connection in service.
• Measured reliability metrics — Clear leakage, insulation resistance and voltage-proof specifications provide verifiable electrical performance for design validation.
