LAR2D122MELA50

The LAR2D122MELA50 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose electronic applications. It delivers high bulk capacitance (1.2 mF) at a 200 V rating and is built for elevated-temperature operation up to 105 °C.

Engineered for reliable ripple-current performance and enhanced overvoltage behavior, this radial can (snap-in) capacitor is suited for designs that require substantial energy storage, dependable endurance at high temperature, and robust mounting on power boards.

Key Features

• High Capacitance / Voltage: 1.2 mF (1,200 µF) rated at 200 V for substantial bulk energy storage in compact radial can format.
• Snap-in Terminal Package: Radial, can-type with snap-in terminals for secure PCB mounting and ease of assembly.
• High Temperature Endurance: Rated for operation up to 105 °C and specified to withstand 2,000 hours of applied rated ripple current at 105 °C.
• Rated Ripple Current: 2.65 A at 120 Hz and 3.975 A at 50 kHz, with frequency coefficients provided for other operating frequencies.
• Permissible Overvoltage and Safety Behavior: Designed to reduce incidence of shorts under overvoltage (rated voltage × 1.5); safety performance shows more than 60% passing under defined overvoltage test conditions.
• Polarized, Tight Tolerance: Polarized capacitor with capacitance tolerance of −20% to +20% (±20% at 120 Hz, 20 °C).
• Leakage and Loss Characteristics: Leakage current defined as I ≤ 3√CV (µA) after 5 minutes at 20 °C; tan δ (loss angle) maximum 0.15 for 200–400 V parts (measured at 120 Hz, 20 °C).
• RoHS Compliant: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power electronics: Bulk energy storage and smoothing where 200 V rating and high ripple-current endurance are required.
• Industrial equipment assemblies: Use in boards requiring robust, high-temperature capacitors with snap-in mounting for secure mechanical retention.
• Electronic assemblies with elevated operating temperature: Circuits that need long-term ripple handling at up to 105 °C and reliable end-of-life behavior.

Unique Advantages

• Large-capacitance, high-voltage combination: 1.2 mF at 200 V provides substantial bulk capacitance for power-conditioning needs without multiple smaller parts.
• Designed for continuous high-temperature ripple: Specified to withstand 2,000 hours of rated ripple current at 105 °C, simplifying thermal and reliability planning.
• Snap-in radial can package: Facilitates strong mechanical mounting and straightforward assembly on power PCBs.
• Overvoltage safety mitigation: Construction reduces short incidence under 1.5× rated voltage and meets defined passing criteria in overvoltage testing.
• Frequency-aware ripple ratings: Published frequency coefficients allow designers to scale ripple-current capability across 50 Hz–50 kHz operating ranges.
• Regulatory compliance: RoHS conformity supports deployments where restricted-substance compliance is required.
