UKT1A222MHD

The UKT1A222MHD is a radial-lead aluminum electrolytic capacitor offering 2200 µF capacitance with a rated voltage of 16 V. Designed for audio and general-purpose electronic equipment, it provides wide temperature operation from −55°C to +105°C and an endurance rating of 1000 hours at 105°C.

As a through-hole radial can device, the UKT1A222MHD delivers high bulk capacitance in a compact φ12.5 × 20 mm package with 5 mm lead spacing, and is offered in bulk or bag packing for production and prototyping workflows. The part is AEC‑Q200 listed and RoHS compliant.

Key Features

• Capacitance and Tolerance: 2200 µF (2.2 mF) with ±20% tolerance measured at 120 Hz and 20°C, providing substantial bulk energy storage for smoothing and decoupling.
• Rated Voltage: 16 V nominal rating suitable for low-voltage audio and power-supply applications.
• Temperature and Endurance: Operating range −55°C to +105°C with a life/endurance specification of 1000 hours at 105°C.
• Loss Characteristics: tan δ (DF) 0.24 measured at 20°C, 120 Hz, allowing assessment of dissipation for thermal and reliability planning.
• Ripple and Leakage: Low-frequency ripple current 810 mA (120 Hz) and high-frequency ripple current 931.5 mA (10 kHz); leakage current specified at 660 µA for system leakage budgeting.
• Package and Mounting: Radial lead, can-style package: φ12.5 × 20 mm with 5 mm lead spacing (±0.5 mm) for through-hole assembly and robust mechanical mounting.
• Compliance and Packaging: AEC‑Q200 listed and RoHS compliant; available in Bulk (no terminal forming) or Bag packing.
• Lifecycle Status: End Of Life — for planning and procurement, consider lifecycle implications in your BOM.

Typical Applications

• Audio Power Supply Filtering: Bulk energy storage and smoothing for audio amplifier rails to reduce low-frequency ripple and improve power stability.
• Power Supply Decoupling: Local reservoir and decoupling in low-voltage power rails where high capacitance is required in a compact through-hole package.
• Embedded and Industrial Electronics: Through-hole mounting for boards where robust mechanical retention and wide operating temperature are needed.

Unique Advantages

• High Capacitance in a Compact Can: 2200 µF in a φ12.5 × 20 mm package minimizes board footprint while delivering substantial bulk storage.
• Wide Temperature Range: −55°C to +105°C operation supports designs exposed to broad environmental conditions.
• Defined Endurance Performance: 1000 hours at 105°C gives a clear baseline for thermal life and replacement planning.
• Measured AC Performance: Specified low- and high-frequency ripple current values help quantify thermal loading and ripple handling in real circuits.
• Through-Hole Robustness: Radial lead configuration and can package simplify mechanical mounting and rework in prototype and production environments.
• Standards and Compliance: AEC‑Q200 listing and RoHS compliance aid qualification and environmental compliance efforts.
