UKA1E222MHD

The UKA1E222MHD is an aluminum electrolytic, polarized radial-lead capacitor designed for high‑grade audio equipment. It delivers 2.2 mF (2200 µF) at a rated voltage of 25 V in a compact φ12.5 × 30.5 mm can package with 5 mm lead spacing.

Engineered for demanding temperature environments, the device supports an operating range of −55°C to +105°C and is AEC‑Q200 rated, offering long endurance (2000 hours at 105°C) and ripple handling suitable for audio power and decoupling applications.

Key Features

• Capacitance & Voltage — 2200 µF (2.2 mF) nominal capacitance with a rated voltage of 25 V and ±20% tolerance, providing bulk energy storage and smoothing for low‑voltage audio rails.
• Wide Temperature Range — Specified for −55°C to +105°C, enabling use in equipment exposed to broad thermal conditions.
• High Ripple Current Capability — Rated ripple current of 1.2 A (105°C, 120 Hz) and 1.38 A at 10 kHz, supporting dynamic load currents found in audio amplifiers and power supplies.
• Low Leakage — Leakage current of 1650 µA after 1 minute and 550 µA after 2 minutes at 20°C, consistent with long bias stability requirements.
• Loss Characteristics — Tangent of loss angle (tan δ) specified at 0.20, suitable for audio applications where dissipation needs to be controlled.
• Durability & Reliability — Endurance rating of 2000 hours at 105°C; AEC‑Q200 qualification supports use where enhanced component reliability is required.
• Package & Mounting — Radial, can‑style package (φ12.5 × 30.5 mm) with 5 mm lead spacing (±0.5 mm), supplied in bulk with no terminal forming for through‑hole assembly flexibility.

Typical Applications

• Professional Audio Amplifiers — Bulk decoupling and power smoothing on low‑voltage amplifier rails to support dynamic transient currents and stable biasing.
• Mixing Consoles and Signal Processing — Power supply filtering and local energy storage to maintain low noise and steady operation for sensitive audio circuits.
• High‑Grade Consumer Audio Equipment — Filtering and reservoir capacitance in preamplifiers, DAC power stages, and other audio front‑end systems requiring stable performance across wide temperatures.

Unique Advantages

• Designed for Audio Performance — Specified tan δ and capacitance suited for applications where controlled dissipation and stable capacitance matter to audio fidelity.
• Broad Thermal Capability — −55°C to +105°C operating range and 2000‑hour endurance at 105°C provide resilience in challenging environments and long operational life.
• Robust Ripple Handling — High rated ripple currents at both low and high frequencies accommodate supply regulation and dynamic loads typical in audio power stages.
• Verified Reliability — AEC‑Q200 rating supports designs that require proven component robustness and traceable qualification standards.
• Compact Through‑Hole Form Factor — 2200 µF delivered in a φ12.5 × 30.5 mm radial can enables high capacitance density for board‑level power management without large PCB footprint.
• Practical Assembly — Bulk packaging with standard lead spacing simplifies procurement and manual or wave solder assembly processes for through‑hole designs.
