UKT1H220MDD

The UKT1H220MDD is a radial-lead aluminum electrolytic capacitor engineered for general audio equipment. It combines a compact φ5 × 11 mm can with specifications tuned for audio power and signal circuitry, including defined ripple-current capability and low leakage.

Designed for demanding temperature environments, the part supports an operating range of −55°C to 105°C and an endurance rating of 1000 hours at 105°C. The device carries an AEC-Q200 rating and is RoHS compliant, addressing reliability and regulatory needs for sensitive audio designs.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance rated at 50 V with ±20% tolerance measured at 120 Hz, 20°C.
• Low Leakage — Specified leakage current of 33 µA for minimized DC loss in coupling and bypass applications.
• Ripple Current Handling — 68 mA at 120 Hz (low frequency) and 136 mA at 10 kHz (high frequency), supporting power-supply decoupling in audio circuits.
• Wide Temperature Range — Rated for operation from −55°C to 105°C to maintain performance in varied environments.
• Endurance — 1000 hours life at 105°C, with endurance characteristics defined for long-term stability in elevated-temperature applications.
• Package & Mounting — Radial lead, can-style package (φ5 × 11 mm), 2 mm lead spacing; supplied in bulk (no terminal forming) or bag packing.
• AEC-Q200 Rated — Qualified to AEC-Q200 for component-level reliability requirements.
• Environmental Compliance — RoHS compliant for regulatory conformity in modern electronics production.

Typical Applications

• General Audio Equipment — Provides decoupling and smoothing in audio power supplies and signal paths where stable capacitance and defined ripple handling are required.
• Audio Power Supply Filtering — Supports supply-line filtering in amplifiers and preamplifiers with specified ripple-current ratings at both low and high frequencies.
• Temperature-Challenged Audio Electronics — Suitable for audio modules exposed to wide ambient temperature ranges, leveraging the −55°C to 105°C operating window and 1000 h endurance at 105°C.

Unique Advantages

• Balanced ripple and leakage characteristics — Combines measurable ripple-current capability (68 mA @120 Hz, 136 mA @10 kHz) with low leakage (33 µA) to preserve audio fidelity and reduce power loss.
• Compact radial can — φ5 × 11 mm size and 2 mm lead spacing enable space-efficient PCB placement in densely packed audio boards.
• Wide thermal capability — −55°C to 105°C rating and 1000-hour endurance at 105°C support sustained operation in elevated-temperature locations.
• Industry reliability rating — AEC-Q200 qualification provides a documented reliability baseline for applications requiring component-level assurance.
• Regulatory readiness — RoHS compliance simplifies integration into green bill-of-materials (BOM) flows.
