LGR2G271MELC35

The LGR2G271MELC35 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGR Long Life series. It delivers 270 µF at a 400 V rating in a radial, can‑style snap‑in package designed for general‑purpose power applications.

Engineered for sustained ripple environments, this unit is specified for operation from −25 °C to 105 °C and is qualified to withstand 10,000 hours of ripple current application at 105 °C. The device is RoHS compliant.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance, suitable for high‑voltage DC bus applications within the specified rating.
• Snap‑in Radial Package — Snap‑in terminal type in a radial can package for secure board mounting and robust mechanical retention.
• Thermal and Lifetime Performance — Operating temperature range of −25 °C to 105 °C and long life assurance: 10,000 hours of endurance when DC bias plus rated ripple current is applied at 105 °C.
• Ripple Current Handling — Rated ripple current of 1.1 A at 120 Hz and 1.573 A at 50 kHz for the LGR2G271MELC35; frequency coefficients in the LGR series apply to calculate ripple performance across frequencies.
• Endurance & Stability — After the 10,000‑hour endurance test at 105 °C with DC bias and rated ripple, capacitance change remains within ±25% and leakage current stays at or below the initial specified value per series endurance specifications.
• Compliance & Marking — RoHS compliant; sleeve marking is printed in white on a black sleeve per product marking practice.
• Compact Dimensions — Package dimensions approximately L: 3.5 cm × D: 3.5 cm for space‑conscious board layouts.

Typical Applications

• Power Supplies — Bulk filtering and smoothing on 400 V DC rails where long life and sustained ripple endurance are required.
• Industrial Power Electronics — Energy buffering and ripple absorption in general‑purpose industrial equipment operating up to 105 °C.
• General‑Purpose Electronic Equipment — DC link and power conditioning roles in equipment needing RoHS‑compliant, high‑voltage electrolytic capacitors.

Unique Advantages

• Long Life Assurance: Specified to withstand 10,000 hours of ripple current at 105 °C, supporting designs that require proven endurance under sustained thermal and electrical stress.
• High Voltage Capability: 400 V rating enables use on higher DC bus voltages without exceeding the component’s specified limits.
• Defined Ripple Performance: Published ripple current values at 120 Hz and 50 kHz let designers size damping and cooling for real operating frequencies.
• Clear Endurance Criteria: Endurance limits include capacitance change (±25%) and leakage current retention, providing measurable reliability targets for long‑term designs.
• RoHS Compliant: Meets RoHS directive requirements for restricted substances, supporting regulatory compliance in supplied products.
