LAK2D681MELB40

The LAK2D681MELB40 is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose use where sustained high temperature and voltage stability are required. It delivers 680 µF capacitance at a 200 V rating in a radial, can‑style snap‑in package sized approximately 4 × 3 cm.

Engineered for equipment operating in voltage‑fluctuating environments, this capacitor combines high ripple endurance at elevated temperature with enhanced safety features and RoHS compliance to support reliable power filtering and energy buffering in demanding conditions.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High‑temperature Endurance — Designed to withstand 2000 hours of rated ripple current at 105°C; after the endurance test the capacitor meets specified limits for capacitance change, tan δ and leakage current.
• Ripple Current Performance — Rated ripple current of 1.7 A at 120 Hz and 2.04 A at 10 kHz, supporting sustained AC stress at elevated temperatures.
• Permissible Abnormal Voltage / Safety — Improved safety features for abnormally excessive voltage; includes a pressure relief vent and defined limited DC current ratings for abnormal voltage tests (for 200 V, 470 µF ≤ C: limited DC current 7 A under test conditions shown in the datasheet).
• Electrical Characteristics — Leakage current guaranteed by I ≤ 3√(C·V) µA after 5 minutes at 20°C; tan δ ≤ 0.20 at 120 Hz, 20°C.
• Package & Mounting — Radial can with snap‑in terminals for secure board mounting; package dimensions approximately L: 4 cm × D: 3 cm.
• Environmental & Temperature Range — Operating temperature range −25°C to +105°C and RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Equipment used in voltage‑fluctuating areas — Provides stable capacitance and safety features for systems exposed to abnormal voltage excursions.
• General‑purpose power systems — Serves as a bulk or smoothing capacitor where a 200 V, 680 µF snap‑in solution is required.
• High‑temperature installations — Suited to designs that demand sustained performance up to 105°C and verified endurance under rated ripple current.

Unique Advantages

• Validated high‑temperature reliability — 2000 hours endurance at 105°C under rated ripple current provides predictable aging and maintenance planning.
• Robust ripple handling — Specified ripple currents at both 120 Hz and 10 kHz support a range of switching and line‑frequency stress conditions.
• Enhanced safety under abnormal voltage — Pressure relief vent and defined limited DC current test ratings reduce risk during overvoltage events.
• Board‑friendly snap‑in package — Radial, snap‑in can simplifies mechanical mounting for through‑hole assembly and secure connections.
• Regulatory compliance — RoHS compliant to current directives, supporting environmental and procurement requirements.
