LAK2D681MELA50ZB

The LAK2D681MELA50ZB is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LAK series designed for general‑purpose power applications. It provides 680 µF capacitance at a 200 V rating in a radial, snap‑in can (φ25 mm × 50 mm) optimized for board‑level power assemblies and high ripple environments.

This part is engineered for elevated temperature endurance and safety: it is specified for operation from −25 °C to +105 °C with a rated lifetime of 2000 hours at 105 °C, and includes improved safety features for abnormal overvoltage conditions. It is RoHS‑compliant and shipped in tray packing for production use.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Package & Mounting — Snap‑in terminal, radial can package (φ25 mm × 50 mm) for robust board mounting and secure mechanical retention.
• Thermal & Lifetime — Designed for −25 °C to +105 °C operation and rated for 2000 hours at 105 °C under specified conditions.
• Ripple Performance & Leakage — Rated ripple capability of 1.7 A (120 Hz) and 2.04 A (10 kHz) with typical leakage current around 1.1 mA.
• Safety & Overvoltage Tolerance — Series design includes improved safety features and a pressure relief vent to manage abnormal excessive voltage conditions.
• Production Ready — RoHS‑compliant and supplied in tray packing; product listed as mass production status.

Typical Applications

• General‑purpose power assemblies — Bulk filtering and energy storage on power supply boards that require a 200 V, high‑capacitance snap‑in solution.
• Voltage‑fluctuating equipment — Suited for equipment operating in environments with fluctuating voltages due to its enhanced safety features and voltage endurance.
• High‑ripple circuits — Applicable where elevated ripple currents occur; specified ripple ratings at 120 Hz and 10 kHz support reliable smoothing performance.

Unique Advantages

• High voltage handling: 200 V rating enables use in higher‑voltage designs while maintaining compact 25 mm diameter sizing.
• Snap‑in mounting: Radial snap‑in terminals provide secure mechanical retention for high‑stress or vibration‑prone assemblies.
• High temperature endurance: 2000‑hour rating at 105 °C supports sustained performance in hot operating environments.
• Measured ripple capability: Specified ripple currents of 1.7 A (120 Hz) and 2.04 A (10 kHz) give predictable performance for power smoothing and decoupling tasks.
• Safety features: Pressure relief vent and improved abnormal‑voltage handling reduce risk during overvoltage events.
• Production convenience: Tray packing and mass production status streamline procurement and assembly for volume builds.
