LAQ2D221MELZ25ZB

The LAQ2D221MELZ25ZB is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LAQ series. It delivers 220 µF capacitance at a 200 V rated voltage in a compact φ22 × 25 mm can with polarized snap‑in mounting.

Designed for general‑purpose applications, this part combines high‑voltage capability, defined ripple handling and a 2000‑hour endurance rating at 105°C to meet common power and smoothing requirements in industrial and commercial equipment.

Key Features

• Capacitance & Tolerance — 220 µF nominal with ±20% tolerance (measured at 120 Hz, 20°C).
• Voltage Rating — 200 V rated voltage for higher‑voltage general‑purpose circuits.
• Mounting & Package — Snap‑in terminal radial can (φ22 × 25 mm) for secure PCB mounting and compact board footprint.
• Operating Temperature & Endurance — Rated for −25°C to +105°C with 2000 hours endurance at 105°C under DC bias plus rated ripple current as specified in the series datasheet.
• Ripple Current Performance — 900 mA ripple current at 120 Hz and 1.08 A at high frequency (100 kHz) to support AC superposition on DC lines.
• Low Dissipation Factor — tan δ ≤ 0.20 at 20°C, 120 Hz for controlled loss at mains‑frequency operation.
• Leakage Current — Typical leakage current around 620 µA after rated voltage application at 20°C (per product specification).
• Safety Features — Pressure relief vent design as specified in the LAQ series safety performance section of the datasheet.

Typical Applications

• General‑purpose electronics — Suitable for general‑purpose equipment requiring a 220 µF, 200 V snap‑in electrolytic capacitor.
• Power supply modules — Provides bulk capacitance and ripple handling where a compact, high‑voltage snap‑in part is needed.
• Industrial equipment — Matches applications that demand defined endurance at elevated temperatures up to 105°C.

Unique Advantages

• High voltage capability: 200 V rating allows use in higher‑voltage general‑purpose designs without upsizing the capacitor.
• Compact snap‑in package: φ22 × 25 mm can with snap‑in terminals reduces board area while providing robust mechanical mounting.
• Defined ripple performance: 900 mA at 120 Hz and 1.08 A at 100 kHz give clear limits for thermal and ripple planning in power circuits.
• Engineered for endurance: 2000 hours at 105°C under rated conditions supports reliable operation in elevated ambient temperatures.
• Controlled loss and leakage: tan δ ≤ 0.20 and ~620 µA leakage current enable predictable electrical behavior for design verification.
• Series safety provisions: Pressure relief vent performance specified in the LAQ series enhances safe failure modes per the datasheet.
