LAR2E471MELZ40

The LAR2E471MELZ40 is a snap‑in terminal aluminum electrolytic capacitor offering 470 µF capacitance at a 250 V rating in a radial, can‑style snap‑in package (φ22 × 40 mm). It is polarized and designed for general purpose power applications that require bulk energy storage and smoothing at elevated temperatures.

Key value propositions include high temperature endurance (2000 hours at 105°C under rated ripple current), measurable ripple current capability, and RoHS compliance—providing a robust option where long life, safety under stress, and straightforward board mounting are priorities.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance at a 250 V rated voltage with ±20% tolerance for bulk energy storage and smoothing in DC circuits.
• Snap‑in Radial Can Package — Snap‑in terminal, radial can design (φ22 × 40 mm) for secure mechanical mounting and automated or manual assembly.
• High Temperature Endurance — Rated for 2000 hours at 105°C when subjected to D.C. bias plus rated ripple current, with capacitance change within ±20% after endurance testing.
• Ripple Current Capability — Rated ripple current values include 1.4 A at 120 Hz and 2.1 A at 50 kHz, with frequency coefficients provided for performance scaling across frequencies.
• Leakage Current Specification — Leakage current meets I ≤ 3√CV (µA) after 5 minutes’ application of rated voltage at 20°C (C in µF, V in V).
• Low‑Temperature Stability — Impedance characteristics defined for low temperatures: for 200/250 V parts, Z(–25°C)/Z(+20°C) ≤ 3 and Z(–40°C)/Z(+20°C) ≤ 12.
• Safety Under Overvoltage — Reduced incidence of shorts under overvoltage conditions; when 1.5 × rated voltage (limited current 1 A) is applied, more than 60% of parts meet passing criteria related to vent behavior and absence of short or flame.
• Regulatory Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Power Circuits — Bulk energy storage and smoothing where a polarized 250 V, 470 µF capacitor is required.
• Power Supply Filtering — Supports DC bias plus rated ripple current and offers frequency‑dependent ripple handling for filtering tasks across a range of switching frequencies.
• Industrial Electronics — Suited for general purpose modules that demand elevated temperature endurance up to 105°C and reliable snap‑in mounting.

Unique Advantages

• Long High‑Temperature Life: 2000 hours endurance at 105°C under rated ripple current reduces maintenance and replacement frequency in hot environments.
• Measured Ripple Performance: Specified ripple current at multiple frequencies (1.4 A at 120 Hz; 2.1 A at 50 kHz) and published frequency coefficients allow predictable thermal and ripple design margins.
• Safety‑Focused Design: Documented reduction of short incidence under 1.5× overvoltage with defined passing criteria supports safer overvoltage behavior in stressed conditions.
• Clear Electrical Limits: Leakage current and tan δ limits are defined (I ≤ 3√CV µA; tan δ max. 0.15 for 200–400 V range), enabling straightforward verification against system requirements.
• RoHS Compliance: Meets RoHS requirements, simplifying regulatory acceptance for many commercial and industrial products.
• Secure Mounting: Snap‑in radial can package provides robust mechanical retention for board‑level assemblies.
