UKT1C221MED

The UKT1C221MED is a miniature radial aluminum electrolytic capacitor from Nichicon's UKT series, specified for audio equipment. It provides 220 µF capacitance at a 16 V rating in a compact radial can package designed for through‑hole PCB mounting.

Engineered for audio applications, this polarized capacitor combines a wide operating temperature range (−55 °C to +105 °C), defined ripple current capability, and an AEC‑Q200 rating to support designs that demand stable performance across temperature and frequency.

Key Features

• Capacitance & Voltage: 220 µF nominal capacitance with a 16 V rated voltage and tolerance of −20% to +20% for predictable DC decoupling and energy storage.
• Compact Radial Package: Radial, can style package with dimensions L: 1.1 × D: 0.63 cm and 2.5 mm lead spacing for tight PCB layouts and through‑hole assembly.
• Wide Temperature Range: Operational from −55 °C to +105 °C, suitable for audio equipment exposed to broad environmental conditions.
• Ripple Current Capacity: Rated ripple current of 190 mA at 120 Hz and 285 mA at 10 kHz, supporting filtering and smoothing in audio power circuits across low and high frequencies.
• Reliability & Lifetime: Designed for 1000 hours at 105 °C; endurance specifications restore nominal characteristics after rated voltage application and thermal cycling per the datasheet.
• Standards & Compliance: AEC‑Q200 rated and RoHS compliant, and polarization clearly indicated for correct circuit installation.
• Leakage and Loss Characteristics: Datasheet specifies leakage current limits based on C×V (0.03CV μA after 1 minute, 0.01CV μA after 2 minutes) and a maximum tan δ of 0.22 at 16 V (120 Hz, 20 °C).

Typical Applications

• Audio Equipment: Intended for general audio equipment where compact, polarized capacitance is required for signal and power sections.
• PCB Power Filtering: Compact radial can configuration and defined ripple ratings make it suitable for decoupling and smoothing on audio PCBs.
• Temperature‑variable Environments: Use in systems that must maintain performance across −55 °C to +105 °C operating range.

Unique Advantages

• Compact Footprint: Small dimensions (1.1 × 0.63 cm) and 2.5 mm lead spacing enable space‑efficient placement in dense audio assemblies.
• Frequency‑aware Ripple Handling: Separate ripple ratings at 120 Hz and 10 kHz provide designers with clear limits for both low‑frequency power smoothing and higher‑frequency decoupling.
• Wide Thermal Range with Defined Lifetime: −55 °C to +105 °C operation and a 1000‑hour endurance at 105 °C help ensure long‑term stability in challenging environments.
• AEC‑Q200 Qualification: Component-level AEC‑Q200 rating supports use in applications requiring recognized passive component reliability testing.
• Measured Electrical Limits: Documented leakage current and tan δ limits allow predictable behavior for precision audio designs.
• Regulatory Compliance: RoHS compliant for straightforward integration into commercial and industrial products.
