LGU2E331MELB

The LGU2E331MELB is an aluminum electrolytic capacitor in a snap‑in terminal radial can package designed for general purpose electronic applications. It provides 330 µF capacitance at a 250 V rating with a snap‑in mounting style and is RoHS compliant.

Designed for high‑temperature operation, this part is specified for operation from −40 °C to +105 °C and delivers long endurance under rated conditions (3000 hours at 105 °C), making it suitable for designs that require sustained performance at elevated temperatures.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance (measured at 120 Hz, 20 °C).
• High‑temperature Endurance — Specified endurance of 3000 hours at 105 °C when subjected to DC bias plus rated ripple current; capacitance change within ±20% after test.
• Ripple Current Capability — Rated ripple current 1.3 A at 120 Hz and 1.95 A at 50 kHz; frequency coefficients provided for 160–250 V parts allow frequency‑dependent ripple scaling.
• Leakage Current Limit — Leakage current specified as I ≤ 3·C·V (µA) after 5 minutes’ application of rated voltage at 20 °C.
• Low‑temperature Stability — Impedance ratios at 120 Hz: Z(−25 °C)/Z(+20 °C) ≤ 3 and Z(−40 °C)/Z(+20 °C) ≤ 12 for 160–250 V range.
• Mounting & Package — Snap‑in terminal radial can for secure PCB installation; package dimensions L: 2.5 × D: 3 cm with seated height specified.
• Environmental Compliance — RoHS compliant.
• Dissipation Factor (tan δ) — Maximum tan δ = 0.15 (measured at 120 Hz, 20 °C) for the 160–420 V range applicable to this 250 V part.

Typical Applications

• General purpose power filtering — Suitable where a 250 V, 330 µF electrolytic is required for bulk capacitance and smoothing in electronic equipment labeled as general purpose.
• Industrial and commercial electronics — Intended for general purpose use in equipment operating within −40 °C to +105 °C and benefiting from long high‑temperature endurance.
• PCB‑mounted power modules — Snap‑in radial can package supports secure mounting in assemblies requiring stable electrical performance at elevated temperature.

Unique Advantages

• Long high‑temperature reliability: 3000 hours endurance at 105 °C under rated ripple current preserves capacitance and leakage characteristics for extended service life.
• Clear ripple performance data: Published ripple current values (1.3 A at 120 Hz, 1.95 A at 50 kHz) and frequency coefficients for the 160–250 V range simplify thermal and ripple budgeting.
• Robust leakage specification: Leakage limited by I ≤ 3·C·V (µA) after initial voltage application, allowing predictable current behavior after assembly.
• Temperature performance characterized: Specified impedance ratios at −25 °C and −40 °C (120 Hz) provide known low‑temperature behavior for system margining.
• RoHS‑compliant construction: Meets RoHS environmental requirements for contemporary electronic product development.
• Practical snap‑in package: Radial, snap‑in can offers a secure PCB attachment and compact footprint (L: 2.5 × D: 3 cm) for space‑constrained board layouts.
