LAR2D102MELA45

The LAR2D102MELA45 is a snap-in terminal aluminum electrolytic capacitor providing 1000 µF of capacitance at a 200 V rated voltage. Designed for general-purpose electronic applications, it delivers high-voltage bulk capacitance with elevated temperature endurance.

Key value comes from its 105°C permissible overvoltage design and long-duration ripple endurance, enabling reliable smoothing and energy storage in systems that require sustained performance at elevated temperature and voltage levels.

Key Features

• Capacitance & Voltage: 1 mF (1000 µF) nominal capacitance with a rated voltage of 200 V for high-voltage bulk storage.
• High-Temperature Endurance: Rated for operation from −40 °C to +105 °C with a specified lifetime of 2000 hours at 105 °C under D.C. bias plus rated ripple current.
• Snap-In Terminal Package: Radial, can-type snap-in construction for secure mechanical mounting and simplified board installation.
• Ripple Current Capability: Rated ripple current 2.3 A at 120 Hz and 3.45 A at 50 kHz, with frequency coefficients available for scaling ripple across common frequencies.
• Overvoltage Safety Design: Constructed to reduce short incidence when exposed to 1.5× rated voltage; safety performance testing shows a defined passing condition under overvoltage (limited current = 1 A).
• Electrical Quality: Capacitance tolerance ±20% (at 120 Hz, 20 °C). Leakage current specified by I ≤ 3√CV (µA) after 5 minutes at 20 °C; tan δ (loss tangent) max. 0.15 at 120 Hz for 200–400 V ratings.
• RoHS Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering: Bulk smoothing and decoupling in high-voltage power supplies where 200 V capacitance and elevated temperature endurance are required.
• DC bus energy storage: Local energy storage and smoothing on DC links for converters and power stages, leveraging the 1000 µF capacitance and rated ripple current.
• High-temperature environments: Circuits that operate near 105 °C benefit from the capacitor’s specified 2000-hour ripple endurance at that temperature.

Unique Advantages

• Long ripple-endurance at elevated temperature: Withstands 2000 hours of rated ripple current at 105 °C, supporting reliable long-term operation in hot environments.
• High-voltage capability: 200 V rating provides margin for higher-voltage system designs that need substantial bulk capacitance.
• Snap-in mounting for robust installation: Snap-in terminal design simplifies PCB assembly and enhances mechanical retention compared with standard axial leads.
• Overvoltage mitigation: Designed to reduce short incidence under 1.5× rated voltage conditions and validated by series safety performance tests.
• Measurable electrical limits: Clear specifications for leakage current (I ≤ 3√CV), tan δ (max. 0.15 at 120 Hz for 200–400 V), and frequency coefficients for ripple scaling enable predictable design integration.
• Regulatory compliance: RoHS-compliant construction supports deployments requiring restricted-substance adherence.
