UAQ2D181MHD6

The UAQ2D181MHD6 is an aluminum electrolytic capacitor in a radial-lead can package designed for general-purpose power applications. It provides 180 µF capacitance at a 200 V rated voltage with a ±20% tolerance and a compact φ18 × 30.5 mm footprint with 7.5 mm lead spacing.

Engineered for wide temperature operation and high ripple handling, this part supports operation from −40°C to +105°C and is specified for 2000 hours at 105°C. The product is RoHS compliant. Note: this product is scheduled to be discontinued and is not recommended for new designs.

Key Features

• Electrical Performance — 180 µF capacitance at 200 V rated voltage with ±20% tolerance and a maximum tanδ of 0.15 (measured at 120 Hz, 20°C).
• High Ripple Capability — Specified ripple current of 495 mA at 120 Hz and 792 mA at 10 kHz to support demanding AC ripple and filtering tasks.
• Leakage and Loss Characteristics — Leakage current aligned with datasheet limits (example: 0.04CV+100 µA formula applies per series specification).
• Wide Temperature Range — Rated for operation from −40°C to +105°C, with endurance specified for 2000 hours at 105°C under DC bias plus rated ripple current.
• Radial Lead, Through-Hole Package — φ18 × 30.5 mm can with 7.5 mm lead spacing, suitable for classic through-hole assembly and serviceable power electronics layouts.
• Safety Design — Includes a pressure relief vent feature specified in the series datasheet to mitigate abnormal over-voltage conditions.
• RoHS Compliant — Meets RoHS requirements per the supplied product data.

Typical Applications

• General-purpose power circuits — Filtering, smoothing and bulk energy storage in general electronic equipment.
• Power supply stages — DC bus and reservoir capacitor use where 200 V rating and elevated ripple handling are required.
• Industrial and instrumentation equipment — Applications requiring wide temperature operation and defined endurance at 105°C.

Unique Advantages

• High ripple endurance: Specified ripple currents at both low and high frequencies enable stability under significant AC ripple loads.
• Wide operating temperature and proven endurance: Rated −40°C to +105°C with 2000 hours endurance at 105°C, supporting long-duration elevated-temperature use cases.
• Compact radial footprint: φ18 × 30.5 mm can and 7.5 mm lead spacing balance capacitance and board-space efficiency for through-hole designs.
• Safety-focused construction: Pressure relief venting reduces risk during abnormal over-voltage events as specified in the series documentation.
• Standards alignment: RoHS compliance supports use in designs requiring lead-free materials per the provided product data.
