LAR2E821MELB35

The LAR2E821MELB35 is a snap‑in terminal aluminum electrolytic capacitor featuring 820 µF capacitance and a 250 V rated voltage. It is a polarized, radial can design intended for general‑purpose power electronics where high ripple endurance and elevated operating temperature capability are required.

Designed to withstand 2000 hours of rated ripple current at 105°C and to reduce short incidence under overvoltage conditions, this part delivers durable smoothing and energy‑storage performance in industrial and power conversion applications.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High‑temperature Endurance — Specified to endure 2000 hours at 105°C under DC bias plus rated ripple current with limits on capacitance change, tan δ, and leakage current.
• Ripple Current Capability — Rated ripple current of 2 A at 120 Hz (low frequency) and 3 A at 50 kHz (high frequency); frequency coefficient of rated ripple current rises to 1.50 at 50 kHz or more for 200/250 V parts.
• Overvoltage Safety Performance — Designed to reduce short incidence when subjected to overvoltage (rated voltage × 1.5); more than 60% of capacitors pass the overvoltage test condition specified in the datasheet.
• Temperature Range & Low‑temp Stability — Operates from –40°C to +105°C; impedance and stability characteristics are specified across the range.
• Package & Mounting — Radial, snap‑in can package for secure board mounting; physical size L: 3.5 cm × D: 3.0 cm and seated height maximum 1.378 inch.
• Leakage Current Specified — Leakage current after 5 minutes at 20°C follows I ≤ 3√CV (µA), where C is µF and V is volts.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supply Filtering — Bulk smoothing and decoupling in medium‑voltage DC power supplies where high ripple endurance at elevated temperature is required.
• Industrial Power Conversion — Energy storage and filter stages in industrial inverters and converters operating up to 105°C ambient or elevated internal temperatures.
• UPS and Backup Systems — Smoothing and short‑term energy buffering in uninterruptible power supply modules and related energy management circuits.

Unique Advantages

• Proven High‑Temperature Reliability: Endurance rating of 2000 hours at 105°C under rated ripple current supports designs targeting elevated operating temperatures.
• Robust Ripple Handling: Specified ripple current values and a frequency coefficient up to 1.50 at high frequencies enable predictable thermal and lifetime behavior under AC stress.
• Snap‑In Mechanical Stability: Radial snap‑in can package provides secure board retention for power modules and heavy vibration environments.
• Overvoltage Mitigation: Reduced short incidence under 1.5× rated voltage conditions enhances safety margins in fault scenarios.
• Standards‑oriented Electrical Limits: Leakage current and tan δ specifications are explicitly defined, enabling accurate margining in design and verification.
• Regulatory Compliance: RoHS conformity reduces material compliance overhead for commercial and industrial products.
