LAR2E561MELB30

The LAR2E561MELB30 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LAR series. It delivers 560 µF capacitance at a 250 V rating and is designed for general‑purpose use where a robust high‑voltage electrolytic capacitor is required.

This part supports elevated thermal and ripple stress: it is specified for operation up to 105°C with endurance under rated ripple conditions and includes design features to reduce short incidence when subjected to overvoltage conditions.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance (at 120 Hz, 20°C).
• High‑temperature endurance — Specified to withstand 2000 hours of DC bias plus rated ripple current at 105°C with capacitance change within ±20% after testing.
• Overvoltage safety behavior — Designed to reduce short incidence under overvoltage (rated voltage × 1.5); series safety testing shows that a majority of parts pass defined pressure‑relief conditions under limited current overvoltage stress.
• Ripple current capability — Rated ripple current: 1.5 A at 120 Hz (low frequency) and 2.25 A at 50 kHz (high frequency). Frequency coefficients for 200/250 V parts: 50 Hz = 0.81, 60 Hz = 0.85, 120 Hz = 1.00, 300 Hz = 1.17, 1 kHz = 1.32, 10 kHz = 1.45, ≥50 kHz = 1.50.
• Operating range — Rated for operation from −40°C to +105°C (for 200 and 250 V ratings).
• Leakage current specification — Initial leakage current meets I ≤ 3√(C·V) µA after 5 minutes at 20°C (C = µF, V = rated voltage).
• Package & mounting — Radial can, snap‑in terminal type for secure PCB mounting; dimensions approximately 3 cm × 3 cm with printed white marking on a black sleeve.
• Shelf life and stability — Shelf life specification: after 1000 hours at 105°C (no load) and subsequent voltage treatment, capacitance change within ±15% and leakage current meeting initial limits.
• RoHS compliant — Complies with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power electronics — Suitable wherever a 560 µF, 250 V snap‑in aluminum electrolytic is needed for general power circuitry.
• High‑temperature environments — Deployment in assemblies that require capacitor performance up to 105°C and endurance under rated ripple conditions.
• PCB mounted radial designs — Snap‑in can package for secure mounting in electronic assemblies that use radial snap‑in components.

Unique Advantages

• Validated high‑temperature endurance — 2000‑hour rated endurance at 105°C with DC bias and rated ripple current reduces the need for frequent field replacements.
• Measured ripple capability across frequencies — Published ripple current ratings and frequency coefficients allow designers to size the part for a wide range of operating frequencies.
• Overvoltage resilience — Series testing for 1.5× rated voltage with limited current demonstrates reduced short incidence and controlled pressure‑relief behavior under stress.
• Clear electrical limits — Leakage current and tan δ limits are specified and testable (I ≤ 3√CV µA; tan δ limits for rated voltage ranges), supporting predictable system behavior and testability.
• Regulatory compliance — RoHS compliance simplifies use in designs requiring restricted‑substance adherence.
• Practical packaging — Snap‑in radial can with clear sleeve marking simplifies identification and assembly for production environments.
