UAQ2G220MHD

The UAQ2G220MHD is a radial-lead aluminum electrolytic capacitor rated at 22 µF and 400 V. It is designed as a general-purpose, polarized capacitor with a compact radial can package (φ12.5 × 30.5 mm) for through-hole assemblies.

Key attributes include high ripple current capability, an extended operating temperature range of -40°C to 105°C, and built-in safety features for abnormal voltage conditions. The device is RoHS compliant and supplied in bulk or bag packing.

Key Features

• Capacitance & Tolerance — 22 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C).
• Voltage Rating — 400 V DC rated voltage for high-voltage circuit requirements.
• Ripple Current Performance — Specified low-frequency ripple current: 145 mA at 120 Hz; high-frequency ripple current: 232 mA at 10 kHz.
• Leakage Current — Specified leakage current of 452 µA (part-specific value).
• Temperature & Endurance — Operating range -40°C to 105°C with endurance rated at 2000 hours at 105°C.
• Loss Tangent — tanδ (DF) max 0.15 at rated conditions.
• Mechanical & Mounting — Radial lead, can-style package; physical size φ12.5 × 30.5 mm (D × L); lead spacing 5.0 mm with ±0.5 mm tolerance.
• Safety & Compliance — Improved safety feature for abnormally excessive voltage and pressure relief vent; RoHS compliant.
• Packaging Options — Available in Bulk (No Terminal Forming) or Bag Packing for production or repair volumes.

Typical Applications

• General-purpose electronic equipment — Provides 22 µF/400 V polarized capacitance for through-hole assemblies and legacy designs.
• High-voltage power circuits — Supports elevated DC voltages and specified ripple currents across low and high frequencies.
• Thermally demanding environments — Rated for -40°C to 105°C with 2000 h endurance at 105°C for sustained elevated-temperature use.

Unique Advantages

• High-voltage capability: 400 V rating permits use where elevated DC bus capacitance is required.
• Predictable ripple performance: Specified ripple currents at both 120 Hz and 10 kHz enable predictable behavior across frequency ranges.
• Wide temperature and proven endurance: -40°C to 105°C rating plus 2000 h endurance at 105°C supports reliability under thermal stress.
• Built-in safety measures: Improved safety against abnormal over-voltage and a pressure relief vent reduce risk during stress conditions.
• Easy through-hole integration: Radial lead, compact can package and standard 5.0 mm lead spacing simplify placement in through-hole boards.
• RoHS compliance and flexible packing: Meets RoHS requirements and is available in bulk or bag packing to match production or service needs.

Why Choose UAQ2G220MHD?

The UAQ2G220MHD combines a 22 µF capacitance with a 400 V rating, defined ripple-current specifications, and a wide operating temperature range to provide a reliable, predictable solution for high-voltage, through-hole capacitor needs. Its safety-focused design and RoHS compliance make it suitable for maintenance, repair, and production runs that require a known high-voltage electrolytic component.
