LAR2D222MELC45

The LAR2D222MELC45 is an aluminum electrolytic, snap-in terminal capacitor rated at 2200 µF and 200 V, offered in a radial can snap‑in package (φ35 × 45 mm). It is designed for general-purpose applications requiring bulk capacitance, high ripple endurance, and robust thermal performance.

Key value propositions include a high permissible operating temperature of up to 105°C with a guaranteed 2000 hours endurance under rated ripple conditions, measurable ripple current capability across low and high frequencies, and construction features that reduce short incidence under overvoltage conditions. The part is RoHS compliant.

Key Features

• Core Type Aluminum electrolytic capacitor with polar construction for bulk energy storage and smoothing in general-purpose equipment.
• Capacitance & Voltage 2.2 mF (2200 µF) nominal capacitance at a rated voltage of 200 V with tolerance ±20%.
• Ripple Current Performance Rated ripple current of 3.48 A at 120 Hz and 5.22 A at 50 kHz; frequency coefficients increase with frequency (up to 1.50 at 50 kHz or more for 200/250 V range) as documented in the datasheet.
• Thermal & Lifetime Operating temperature range –40°C to +105°C with endurance meeting specified characteristics after 2000 hours at 105°C under D.C. bias plus rated ripple current.
• Reliability & Safety Designed to reduce incidence of shorts when subjected to overvoltage (1.5 × rated voltage); safety performance testing indicates more than 60% passing rate under controlled overvoltage conditions (limited current = 1 A).
• Leakage & Dissipation Leakage current specified as I ≤ 3√(C·V) µA after 5 minutes at 20°C; tan δ max 0.15 for 200–400 V range at 120 Hz, 20°C.
• Mechanical Radial, can-type snap‑in package (φ35 × 45 mm) for secure mounting in through-hole assemblies.
• Environmental Compliance Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply smoothing Provides bulk capacitance and ripple filtering in general-purpose power supplies and converters.
• Industrial equipment Suitable for general-purpose industrial electronics that require high-capacitance bulk storage with elevated temperature endurance.
• Commercial electronics Used where reliable long-term smoothing and energy buffering are needed in commercial devices operating within –40°C to +105°C.

Unique Advantages

• High-temperature endurance: 2000 hours at 105°C under rated ripple current delivers predictable performance in elevated-temperature environments.
• Measured ripple capability: Clear ripple current ratings at 120 Hz and 50 kHz, plus frequency coefficients, allow confident selection for both low- and high-frequency applications.
• Overvoltage safety design: Engineered to reduce short incidence and validated under 1.5× rated voltage conditions with limited current, improving safety margins in transient events.
• Robust leakage and loss specifications: Leakage current formula and tan δ limits enable straightforward qualification against system requirements.
• Secure snap-in mounting: Radial snap-in can simplifies assembly and mechanical retention in through-hole power modules.
• RoHS compliance: Meets current RoHS requirements for environmental and regulatory consistency.
