LAK2D681MELA50

The LAK2D681MELA50 is a snap‑in terminal aluminum electrolytic capacitor rated at 680 µF and 200 V, designed for general-purpose power applications. Its snap‑in can package, RoHS compliance, and a broad operating range (‑25°C to 105°C) make it suitable for equipment that requires reliable bulk capacitance and sustained ripple handling in voltage‑fluctuating environments.

Key Features

• Capacitance & Voltage: 680 µF nominal capacitance at a 200 V rated voltage, with ±20% tolerance for bulk energy storage and smoothing.
• High Ripple Capability: Rated ripple current of 1.7 A at 120 Hz (low frequency) and 2.04 A at 10 kHz (high frequency) to support AC ripple filtering and switching power stages.
• Endurance & Temperature: Engineered for 2000 hours of rated performance at 105°C; operating temperature range is ‑25°C to 105°C for high‑temperature endurance.
• Loss & Leakage: Low dissipation factor with tan δ ≤ 0.20 (120 Hz at 20°C) and a specified leakage current of 1100 µA, for predictable performance in DC circuits.
• Safety & Robustness: Improved safety features for abnormally excessive voltage and a pressure relief vent designed to operate without dangerous conditions such as flames or dispersion of case fragments.
• Mechanical Package: Radial can, snap‑in mounting in a compact 25 mm diameter × 50 mm length footprint with tray packing for production assembly.
• Compliance: RoHS compliant.

Typical Applications

• Power Supply Filtering: Bulk smoothing and decoupling in switch‑mode and linear power supplies where 200 V rating and high ripple capability are required.
• Industrial Power Electronics: DC link or filter capacitor in industrial converters and equipment operating in voltage‑fluctuating environments.
• Energy Storage for UPS & Backup: Local energy buffering and transient energy support in uninterruptible power and standby systems.
• Motor Drives & Inverters: Filtering and energy storage for drive electronics and inverter stages subject to high ripple currents and elevated operating temperatures.

Unique Advantages

• High ripple handling: Supports 1.7 A at 120 Hz and 2.04 A at 10 kHz, enabling effective AC ripple mitigation across a range of switching frequencies.
• Long high‑temperature endurance: Rated for 2000 hours at 105°C when subjected to rated ripple current and DC bias, providing predictable lifetime under sustained thermal stress.
• Safety‑focused design: Improved voltage‑abuse features and a pressure relief vent reduce the risk of hazardous failure modes under abnormal conditions.
• Compact snap‑in format: Radial snap‑in can simplifies PCB mounting for high‑current, high‑density power assemblies and supports efficient mass production (tray packing).
• Measured electrical stability: Tight control of dissipation (tan δ ≤ 0.20) and specified leakage current (1100 µA) aid in predictable circuit behavior and thermal budgeting.
• Regulatory compliance: RoHS compliance eases integration into designs targeting modern environmental requirements.
