LAR2D102MELB30

The LAR2D102MELB30 is a snap-in terminal type aluminum electrolytic capacitor offering 1000 µF capacitance at a 200 V rating in a radial can (φ30 × 30 mm). It is a polarized, general-purpose capacitor designed for applications that require bulk energy storage and high ripple tolerance within a compact snap-in package.

Key value propositions include long high-temperature endurance (2000 hours at 105 °C with rated ripple current), measurable ripple-current performance across frequencies, and enhanced safety behavior under overvoltage conditions. The part is RoHS compliant.

Key Features

• Capacitance & Voltage: 1000 µF nominal capacitance with a 200 V rated voltage, tolerance ±20% at 120 Hz, 20 °C.
• Package & Mounting: Radial, snap-in terminal can with dimensions approximately φ30 × 30 mm for secure PCB mounting.
• Operating Temperature: Specified for –40 °C to +105 °C operation.
• High-Temperature Endurance: Endurance specified as 2000 hours at 105 °C with D.C. bias plus rated ripple current applied; capacitance change remains within ±20% after the test.
• Ripple Current Performance: Rated ripple current of 2.3 A at 120 Hz and 3.45 A at 50 kHz for this part; frequency coefficient for 200/250 V series reaches up to 1.50 at 50 kHz, improving allowable ripple at higher frequencies.
• Safety under Overvoltage: Series-level design reduces incidence of short when exposed to 1.5× rated voltage and includes pressure-relief behavior under limited-current overvoltage conditions.
• Leakage Current & Loss: Leakage current specification follows I ≤ 3√CV (µA) after 5 minutes at 20 °C; tangent of loss angle (tan δ) maximum for 200–400 V range is 0.15 (measured at 120 Hz, 20 °C).
• Compliance: RoHS directive compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power filtering: Bulk capacitance and rated ripple performance make this capacitor suited for smoothing and filtering in general-purpose circuits.
• General-purpose electronic equipment: Snap-in mounting and 105 °C endurance provide a durable option for a wide range of commercial and industrial designs requiring polarized electrolytic capacitors.
• General-purpose energy storage and decoupling: 1000 µF at 200 V offers usable bulk storage where polarized electrolytic capacitors are specified for general-purpose applications.

Unique Advantages

• Long life at elevated temperature: Specified 2000-hour endurance at 105 °C under rated ripple current helps maintain capacitance and reliability in high-temperature environments.
• Snap-in terminal for robust mounting: Snap-in radial can simplifies PCB installation and mechanical retention for higher-vibration or densely packed assemblies.
• Measured ripple performance across frequencies: Defined ripple current values and series frequency coefficients provide predictable ripple handling from low to high frequencies.
• Overvoltage safety behavior: Series design reduces the incidence of short under 1.5× rated voltage and includes pressure-relief operation as a safety measure.
• RoHS compliant: Meets RoHS directive requirements for restricted substances.
