LAK2D821MELC35ZB

The LAK2D821MELC35ZB is a snap-in, radial can aluminum electrolytic capacitor rated 820 µF at 200 V. Designed for general-purpose power applications, it provides high-capacitance, polarized energy storage in a φ35 × 35 mm package with snap-in terminals and tray packing for mass production.

Key value points include high-temperature endurance to 105°C, defined ripple-current performance across low and high frequency, and safety features for abnormal-voltage conditions—attributes useful for equipment operating in areas with voltage fluctuation.

Key Features

• Capacitance & Voltage — 820 µF rated capacitance with a 200 V rated voltage and ±20% tolerance for stable DC energy storage and decoupling.
• Temperature & Endurance — Rated operating range of -25°C to +105°C and specified endurance of 2000 hours at 105°C under DC bias plus rated ripple current, with capacitance change within ±20% after the test.
• Ripple Current Performance — Low-frequency ripple current of 1.99 A at 120 Hz and high-frequency ripple current of 2.388 A at 10 kHz, supporting sustained ripple handling across typical power frequencies.
• Electrical Losses — Tangent of loss angle (tan δ) specified at 0.20 maximum (120 Hz, 20°C) to characterize dissipation factor under normal conditions.
• Leakage Current Specification — Leakage current limit defined by I ≤ 3√(C·V) µA after 5 minutes application of rated voltage at 20°C, providing a measurable acceptance criterion for leakage.
• Mechanical & Mounting — Snap-in terminal radial can construction, nominal size φ35 × 35 mm (3.5 × 3.5 cm), supplied in tray packing for production assembly.
• Safety Features — Pressure relief vent and design validated for permissible abnormal voltage conditions; series documentation specifies limited DC current test conditions for safety verification at voltages above rating.
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose power equipment — Polarized 820 µF, 200 V capacitance for smoothing and bulk energy requirements in equipment classified as general purpose.
• Equipment operating in voltage-fluctuating areas — Designed with safety features and permissible abnormal-voltage characteristics suited for systems exposed to unstable supply conditions.
• High-temperature environments — Systems that require stable performance up to 105°C and specified long-term endurance under rated ripple conditions.

Unique Advantages

• High-temperature endurance: 2000 hours specified at 105°C under rated ripple and DC bias ensures predictable long-term behavior in hot operating environments.
• Measured ripple capability: Documented ripple current ratings at 120 Hz and 10 kHz allow designers to size capacitors against actual ripple conditions.
• Clear leakage and dissipation limits: Leakage current defined by I ≤ 3√(C·V) µA and tan δ ≤ 0.20 (120 Hz, 20°C) provide explicit acceptance criteria for quality and selection.
• Robust safety design: Pressure relief vent and series-level abnormal-voltage testing reduce the risk of dangerous failure modes under abnormal conditions.
• Production-ready packaging: Tray packing and snap-in terminals simplify high-volume assembly and PCB mounting for mass production lines.
• RoHS compliance: Meets RoHS directive requirements for environmental and regulatory alignment.
