LAK2D221MELZ25

The LAK2D221MELZ25 is a Nichicon LAK series aluminum electrolytic capacitor in a snap‑in terminal radial can. It provides 220 µF of capacitance at a 200 V rating with a compact φ22 × 25 mm package and polarized construction for general purpose electronic designs.

Engineered for demanding thermal and ripple conditions, this part targets applications and equipment exposed to voltage fluctuations and elevated operating temperatures, delivering long endurance and built‑in safety features.

Key Features

• Electrical Performance: 220 µF rated capacitance at 200 V with ±20% tolerance and a tan δ of 0.20 max (120 Hz, 20°C), suitable for stable bulk capacitance requirements.
• Ripple Handling: Rated ripple current of 740 mA at 120 Hz and 888 mA at 10 kHz to support circuits with continuous AC ripple loading.
• Leakage Current: Low leakage specified at 0.62 mA (after rated voltage application), providing predictable standby and bias behavior.
• Reliability & Endurance: 2000 hours life at 105°C under rated conditions, with endurance limits defined for capacitance, tan δ and leakage after test exposure.
• Safety Features: Improved safety design for abnormally excessive voltage and a pressure relief vent that operates under abnormal conditions to reduce hazardous outcomes.
• Package & Mounting: Snap‑in radial can package (φ22 × 25 mm) for secure PCB mounting and robust mechanical retention.
• Operating Range & Polarization: Polarized capacitor rated for operation from −25°C to +105°C.
• Environmental Compliance: RoHS compliant per the series declaration.

Typical Applications

• General purpose electronic circuits — Suited for designs requiring a 220 µF, 200 V snap‑in aluminum electrolytic capacitor for general bulk capacitance needs.
• Equipment in voltage‑fluctuating areas — Designed with improved safety features and endurance for use in equipment exposed to fluctuating voltages.
• PCB snap‑in assemblies — Snap‑in radial can (φ22 × 25 mm) for board mounting where specified ripple current handling (740 mA at 120 Hz; 888 mA at 10 kHz) is required.

Unique Advantages

• High temperature endurance: 2000 hours rated life at 105°C supports long‑term operation in elevated temperature environments.
• Robust ripple capacity: Dual‑frequency ripple ratings (740 mA at 120 Hz and 888 mA at 10 kHz) accommodate diverse AC ripple conditions.
• Safety‑focused design: Improved safety measures and a pressure relief vent reduce hazardous outcomes under abnormal voltage stress.
• Compact snap‑in form factor: φ22 × 25 mm radial can with snap‑in terminals provides secure PCB mounting while minimizing board footprint.
• Controlled electrical loss and leakage: Specified tan δ (0.20 max) and measured leakage (0.62 mA) support predictable performance in bias and standby states.
• Regulatory compliance: RoHS compliance ensures adherence to applicable environmental restrictions.
