LAK2D331MELZ30

The LAK2D331MELZ30 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LAK series, specified for 330 µF at 200 V with a ±20% tolerance. It is a general‑purpose power capacitor designed for applications that require elevated temperature endurance and sustained ripple handling.

Key value comes from its 105°C permissible operating temperature, 2000‑hour endurance at 105°C under rated ripple conditions, and built‑in safety features for abnormal overvoltage conditions as documented in the LAK series datasheet.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at a 200 V rated voltage with ±20% tolerance, suiting bulk filtering and energy‑storage needs.
• High‑Temperature Endurance — Rated for operation from −25°C to +105°C with a life specification of 2000 hours at 105°C under rated ripple conditions.
• Ripple Current Capability — High ripple handling: 1.05 A at 120 Hz and 1.26 A at 10 kHz, supporting sustained AC ripple in power circuits.
• Low Loss — Tangent of loss angle (tan δ) maximum 0.20 at 20°C and 120 Hz, indicating stable dissipation characteristics within the specified condition.
• Leakage Current — Specified leakage current of 770 µA (after rated voltage application), suitable for many power supply topologies.
• Snap‑in Package — Radial can with snap‑in terminals, size φ22 × 30 mm, designed for secure through‑hole mounting and reliable mechanical retention.
• Safety & Reliability — Series features improved safety for abnormally excessive voltage and a pressure relief vent designed to operate without dangerous failure modes.
• Compliance & Availability — RoHS compliant and listed as mass production status by the manufacturer, Nichicon.

Typical Applications

• General‑purpose electronic equipment — Bulk filtering and energy storage in assemblies that require a robust electrolytic capacitor with snap‑in mounting.
• Power supplies and converters — Handles sustained ripple currents (1.05 A at 120 Hz) for smoothing and decoupling in power circuits.
• Equipment exposed to fluctuating voltages — Designed with improved safety features to tolerate abnormal voltage conditions described for the LAK series.

Unique Advantages

• Designed for high‑temperature operation: 2000 hours endurance at 105°C provides predictable ageing characteristics for hot environments.
• Robust ripple performance: Rated ripple currents at both 120 Hz and 10 kHz support a range of switching and mains‑frequency power applications.
• Snap‑in mechanical convenience: Radial snap‑in can (φ22 × 30 mm) simplifies PCB assembly and provides secure mechanical retention for through‑hole designs.
• Measured loss and leakage limits: tan δ ≤ 0.20 and specified leakage current offer quantifiable electrical performance for design verification.
• Improved safety under abnormal voltage: Series safety features and a pressure relief vent reduce risk of hazardous failure modes during overvoltage events.
• RoHS compliant and production ready: Environmentally compliant and in mass production, supporting scalable procurement and consistent supply.
