UAQ2G220MHD6

The UAQ2G220MHD6 is a miniature radial-lead aluminum electrolytic capacitor from Nichicon's UAQ series. It delivers 22 µF capacitance at a 400 V rating in a compact φ16 × 20L can with 7.5 mm lead spacing.

Designed for general-purpose power circuitry, the part combines a wide operating temperature range (−40 °C to 105 °C), high ripple-current capability, and an improved safety feature for abnormally excessive voltage. Note: this product is End Of Life and is not recommended for new designs.

Key Features

• Rated Capacitance — 22 µF with capacitance tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• High Voltage Handling — 400 V rated voltage suitable for high-voltage DC circuits.
• Ripple Current Capability — Low-frequency ripple current of 145 mA (120 Hz) and high-frequency ripple current of 232 mA (10 kHz), supporting applications with elevated ripple stress.
• Electrical Losses — Tangent of loss angle (tan δ) max 0.15 at 20 °C and 120 Hz for predictable dissipation characteristics.
• Leakage Current — Specified leakage current of 452 µA after application of rated voltage at 20 °C.
• Wide Temperature & Endurance — Rated for −40 °C to 105 °C, with endurance specified at 2000 hours at 105 °C under rated conditions.
• Safety Features — Improved safety design for abnormally excessive voltage and a pressure relief vent to reduce hazardous failure modes.
• Compact Radial Can — φ16 × 20L package with 7.5 mm lead spacing (±0.5 mm) for through-hole mounting and compact PCB layouts.
• RoHS Compliant — Meets RoHS directive requirements.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for service and production needs.

Typical Applications

• General-purpose power circuits — Suitable where a 400 V, 22 µF radial-lead electrolytic capacitor is required for DC link, filtering, or energy-storage tasks.
• High-temperature deployments — Components and modules exposed to elevated ambient temperatures up to 105 °C.
• Circuits with elevated ripple — Power supplies and converters that demand higher ripple-current handling at both low and high frequencies.

Unique Advantages

• High-voltage capability — 400 V rating enables use in high-voltage DC circuits without additional series stacking.
• Thermal endurance — 2000-hour life at 105 °C supports sustained operation in hot environments.
• Measured ripple performance — Defined ripple current values at 120 Hz and 10 kHz provide predictable thermal and lifetime behavior under ripple stress.
• Built-in safety measures — Pressure relief vent and improved safety design mitigate hazardous failure modes from abnormal voltages.
• Compact radial format — φ16 can and 7.5 mm lead spacing optimize board real estate for through-hole assemblies and retrofit applications.
• Compliance transparency — RoHS compliance simplifies regulatory tracking for assemblies.

Why Choose UAQ2G220MHD6?

UAQ2G220MHD6 is positioned for engineers and technicians who need a compact, high-voltage electrolytic capacitor with specified ripple handling, wide operating temperature, and defined endurance at elevated temperatures. Its radial-can form factor and clear electrical specifications make it practical for power-supply subsystems and repair/legacy applications where these exact characteristics are required.

Because this part is End Of Life and the UAQ series is scheduled for discontinuation, UAQ2G220MHD6 is most appropriate for maintenance, service replacements, and sustaining legacy designs rather than new product introductions.
