LAR2W271MELB35

The LAR2W271MELB35 is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose, high‑voltage applications. It delivers 270 µF capacitance at a 450 V rating in a radial, can‑style snap‑in package (φ30 × 35 mm) with a -25 °C to +105 °C operating range.

Engineered for programs that require sustained ripple endurance and overvoltage robustness, this capacitor supports 2000 hours of rated ripple current at 105 °C and includes design features to reduce short incidence under overvoltage conditions. It is RoHS compliant.

Key Features

• Capacitance & Voltage — 270 µF rated capacitance at 450 V for high‑voltage bulk energy applications within the general‑purpose category.
• High‑temperature endurance — Specified to withstand 2000 hours of D.C. bias plus rated ripple current at 105 °C; capacitance change remains within ±20% after endurance testing.
• Overvoltage safety performance — Designed to reduce short incidence when subjected to 1.5× rated voltage (limited current = 1 A); more than 60% pass condition under test (pressure relief vent operates normally or remains closed for 10 minutes without short or flame).
• Ripple current ratings — Rated ripple current: 1.23 A at 120 Hz (low frequency) and 1.759 A at 50 kHz (high frequency), with published frequency coefficients for other bands.
• Electrical characteristics — Leakage current governed by I ≤ 3√CV (µA) after 5 minutes at 20 °C; tan δ (loss tangent) max 0.20 for 450 V measured at 120 Hz, 20 °C.
• Package & mounting — Radial, can‑style snap‑in terminal package (φ30 × 35 mm) for secure chassis or board mounting; polarization is required.
• Regulatory compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose high‑voltage circuits — Suited where a 450 V, 270 µF capacitor with robust ripple endurance and high‑temperature capability is required.
• Environments with elevated operating temperature — Applicable where operation up to 105 °C and long ripple endurance (2000 hours at 105 °C) are needed.
• Snap‑in chassis and rack assemblies — Snap‑in radial can package (φ30 × 35 mm) facilitates secure mechanical mounting in power assemblies and modules.

Unique Advantages

• Proven ripple endurance: 2000‑hour qualification at 105 °C under rated ripple current provides predictable performance for extended high‑temperature use.
• Overvoltage robustness: Designed to reduce short incidence under 1.5× rated voltage stress with a defined passing condition for safety vent behavior.
• Clear electrical limits: Leakage current defined by I ≤ 3√CV and tan δ specified (0.20 max at 450 V, 120 Hz, 20 °C) for straightforward design verification.
• Frequency‑aware ripple data: Published ripple current values and frequency coefficients enable accurate ripple handling across low and high frequencies.
• RoHS compliant: Meets RoHS (2011/65/EU, (EU)2015/863) requirements for regulatory alignment in commercial designs.
