UAQ2D181MRD3

The UAQ2D181MRD3 is a miniature radial aluminum electrolytic capacitor in Nichicon's UAQ series, offering 180 µF capacitance at a 200 V rating. It is a polarized, radial-lead can designed for general-purpose power applications that require compact energy storage, smoothing and high ripple handling in a small footprint (φ22 × 25 mm, lead spacing 10 mm).

Engineered with a wide operating temperature range of -40°C to 105°C and a 2000-hour endurance at 105°C, this part combines durable thermal performance with safety features for abnormal-voltage conditions and RoHS compliance.

Key Features

• Rated Capacitance and Voltage — 180 µF nominal capacitance with a 200 V rated voltage, suitable where mid-range voltage bulk capacitance is required.
• Radial Lead, Compact Can — Radial-lead mounting type in a φ22 × 25 mm can with 10 mm lead spacing (±0.5 mm), enabling straightforward through-hole placement and secure electrical connection.
• Thermal and Endurance Performance — Operating range of -40°C to 105°C and rated for 2000 hours at 105°C under DC bias plus rated ripple current, supporting long-term operation at elevated temperature.
• High Ripple Current Capability — Low-frequency ripple current of 495 mA (120 Hz) and high-frequency ripple current of 792 mA (100 kHz), enabling effective ripple handling across a range of frequencies.
• Electrical Characteristics — Capacitance tolerance ±20% (–20% to +20%), tan δ (DF) max 0.15 measured at 20°C, 120 Hz, and specified leakage current (product data: 1540 µA).
• Safety and Reliability — UAQ series includes an improved safety feature for abnormally excessive voltage and a pressure-relief vent designed to operate without creating hazardous conditions under the specified tests.
• Environmental Compliance and Packaging — RoHS-compliant material construction; available in bulk (no terminal forming) or bag packing.

Typical Applications

• General-purpose power filtering — Provides bulk capacitance and ripple suppression in general electronic equipment requiring a 200 V rated radial electrolytic capacitor.
• Power supply smoothing — Suitable for DC bus smoothing and decoupling where 180 µF at 200 V is specified and compact radial mounting is preferred.
• Industrial and consumer electronics — Use in devices and assemblies that need wide temperature operation (−40°C to 105°C) and rated endurance at elevated temperature.

Unique Advantages

• Balanced bulk and voltage capability: 180 µF at 200 V provides a practical combination of energy density and working voltage for many general-purpose power circuits.
• High ripple tolerance: Specified ripple currents (495 mA at 120 Hz and 792 mA at 100 kHz) support reliable performance across low and high ripple frequency environments.
• Wide thermal operating range and proven endurance: −40°C to 105°C operation with 2000 hours endurance at 105°C offers predictable life under elevated temperature stress.
• Safety-focused design: Improved abnormal-voltage safety features and a pressure-relief vent reduce the risk of dangerous failure modes under specified conditions.
• Compact, through-hole form factor: φ22 × 25 mm can with 10 mm lead spacing delivers a space-efficient radial solution for PCB-mounted power designs.
• Regulatory compliance: RoHS-compliant construction supports use in equipment where lead-free compliance is required.
