UKT1C220MDD

The UKT1C220MDD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKT series, offering 22 µF capacitance at a 16 V rating. It delivers performance-oriented characteristics for audio equipment and other electronics that require compact power filtering and decoupling components.

Designed for a wide temperature range (−55°C to 105°C) and backed by 1000 hours of endurance at 105°C, this component balances compact package size and measured electrical performance—including low leakage and specified ripple current ratings—for reliable operation in demanding environments.

Key Features

• Capacitance & Tolerance — 22 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C).
• Voltage Rating — Rated for 16 V DC to support low-voltage audio and electronics power rails.
• Ripple Current Performance — Specified ripple current of 54 mA at low frequency (120 Hz) and 108 mA at high frequency (10 kHz), supporting power-supply smoothing and decoupling in signal chains.
• Low Leakage — Leakage current specified at 10.56 µA, minimizing bias drain and preserving circuit behavior in sensitive designs.
• Environmental & Reliability — AEC-Q200 rated and RoHS-compliant; endurance specified as 1000 hours at 105°C with capacitance change within ±20% after the endurance test.
• Compact Radial Package — φ5 × 11 mm can with 2 mm lead spacing and radial lead mounting for through-hole PCB layouts where board space is limited.

Typical Applications

• Audio equipment — Suited for general audio applications where stable filtering and decoupling are required across a wide temperature range.
• Consumer electronics (audio-focused) — Applicable where a compact, radial-lead electrolytic capacitor with defined ripple and leakage characteristics is needed in audio power chains.
• Industrial audio systems — Can be used in equipment that benefits from extended temperature range and specified endurance at elevated temperatures.

Unique Advantages

• Wide operating temperature: Rated from −55°C to 105°C to maintain electrical characteristics across extreme ambient conditions.
• Endurance at elevated temperature: 1000 hours at 105°C provides a defined life expectancy for thermal-stressed applications.
• Measured ripple capability: Separate ripple current ratings for low and high frequency (54 mA @120 Hz, 108 mA @10 kHz) let designers match component selection to audio supply conditions.
• Low leakage current: 10.56 µA leakage helps preserve bias and reduce standby power draw in sensitive circuits.
• Compact radial form factor: φ5×11 mm can with 2 mm lead spacing supports space-constrained through-hole layouts while keeping installation straightforward.
• AEC-Q200 rated and RoHS compliant: Provides documented reliability and environmental compliance for demanding design requirements.
