LGG2G271MELZ40

The LGG2G271MELZ40 is a snap‑in terminal type aluminum electrolytic capacitor offering 270 µF capacitance at a 400 V rated voltage. It is a polarized, radial can designed for general-purpose electronic applications that require high-voltage bulk capacitance in a compact package.

Key attributes include a 105 °C category temperature, RoHS compliance, snap‑in mounting for secure PCB installation, and series‑level endurance and low‑temperature stability characteristics suited to demanding power environments.

Key Features

• Electrical Performance — 270 µF nominal capacitance at 400 V rated voltage with ±20% tolerance; polarized configuration for DC bulk energy storage.
• Ripple Current — Rated ripple handling of 1.0 A at 120 Hz and 1.43 A at 100 kHz, supporting AC superimposed on DC in power circuits.
• Thermal & Reliability — 105 °C category temperature and specified endurance of 2000 hours at 105 °C when subjected to DC bias plus rated ripple current (capacitors restored to 20 °C for measurement).
• Low-Temperature Stability — Impedance stability characterized for the 400 V range with Z(–25 °C)/Z(+20 °C) ratio up to 8, enabling predictable behavior down to –25 °C.
• Mechanical & Mounting — Snap‑in radial can package, size φ22 × 40 mm (L: 4 × D: 2.2 cm) for secure, vertical PCB installation and compact board footprint.
• Leakage and Dissipation — Series leakage current specification I ≤ 3√(C·V) µA after 5 minutes at 20 °C; tangent of loss angle (tan δ) ≤ 0.15 for rated voltages up to 420 V (measured at 120 Hz, 20 °C).
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose power circuits — Bulk capacitance and voltage rating suited to general electronic equipment requiring polarized high-voltage capacitors.
• Power supply assemblies — Snap‑in mounting and 400 V rating accommodate DC link and smoothing functions where compact high-voltage capacitance is needed.
• Industrial electronic equipment — 105 °C category temperature and 2000 h endurance support continuous operation in elevated-temperature environments.

Unique Advantages

• High-voltage bulk capacitance: 270 µF at 400 V provides substantial energy storage for high-voltage designs without resorting to larger form factors.
• Compact snap‑in package: φ22 × 40 mm radial can with snap‑in terminals simplifies PCB mounting and retention while occupying minimal board area.
• Designed for elevated temperatures: 105 °C rating and 2000 hour endurance at 105 °C under DC bias plus rated ripple current give predictable long-term performance in hot operating conditions.
• Measured ripple capability: Specified ripple currents at 120 Hz and 100 kHz support applications with both low- and high-frequency AC components.
• Low-temperature impedance data: Characterized impedance ratio down to –25 °C for consistent performance across the specified operating range.
• RoHS compliant: Meets environmental requirements for compliant assemblies.
