LAR2E561MELZ45

The LAR2E561MELZ45 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LAR series. It provides 560 µF capacitance at a 250 V rated voltage in a radial, can snap‑in package designed for general‑purpose electronic applications.

Key value propositions include high‑temperature endurance (105 °C), specified ripple handling, and safety measures to reduce short incidence under overvoltage conditions. The part is RoHS compliant for environmental conformity.

Key Features

• Rated capacitance and voltage — 560 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance.
• Package and mounting — Radial, can snap‑in terminal type for secure PCB mounting; physical size φ22 × 45L (D: 2.2 cm × L: 4.5 cm).
• High temperature endurance — Operating temperature range −40 °C to +105 °C with endurance specified as 2000 hours at 105 °C under DC bias plus rated ripple current.
• Ripple current capability — Rated ripple current of 1.5 A at 120 Hz and 2.25 A at 50 kHz (frequency coefficient data available in the series datasheet).
• Leakage and dissipation — Leakage current specified as I ≤ 3√(C·V) µA after 5 minutes at 20 °C; tangent of loss angle (tan δ) max. 0.15 for 200–400 V at 120 Hz, 20 °C.
• Safety performance under overvoltage — Designed to reduce short incidence when subjected to overvoltage (rated voltage × 1.5); series testing shows passing criteria for pressure relief vent operation or no opening without short and flame under specified test conditions.
• Regulatory compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Polarized design — Polarized aluminum electrolytic capacitor suitable for bulk energy storage and filtering in DC circuits.

Typical Applications

• General‑purpose power electronics — Bulk energy storage and smoothing in power supplies and power conversion circuits where 250 V ratings and high capacitance are needed.
• Industrial equipment — Filtering and decoupling in industrial control and power systems that require stable performance up to 105 °C.
• Commercial and consumer electronics — General purpose filtering and energy buffering in electronic equipment that accepts a radial snap‑in capacitor form factor.

Unique Advantages

• Reliable high‑temperature endurance — 2000 hours at 105 °C under rated ripple current ensures long‑term performance in hot operating environments.
• Measured ripple handling — Explicit ripple current ratings at 120 Hz and 50 kHz allow designers to evaluate AC stress limits for filtering and smoothing applications.
• Overvoltage safety characteristics — Series design reduces incidence of shorts when exposed to 1.5× rated voltage under controlled test conditions, improving fault behavior.
• Clear electrical limits — Leakage current formula and tan δ limits are specified for predictable performance and easier design validation.
• Space‑efficient snap‑in can — Radial snap‑in package provides a secure mechanical mounting option for high‑capacitance needs without complex assembly steps.
• RoHS compliance — Conforms to current RoHS directives for use in environmentally regulated products.
