UKT1E220MDD

The UKT1E220MDD from Nichicon is a polarized aluminum electrolytic capacitor in a radial‑lead can package designed for audio and general electronic equipment. It provides 22 µF capacitance at a 25 V rating with a compact φ5 × 11 mm profile and 2.0 mm lead spacing for board‑level mounting.

Engineered for wide temperature operation and endurance, this part supports an operating range of −55 °C to +105 °C and a rated life of 1000 hours at 105 °C, making it suitable for applications that require stable performance across a broad thermal envelope.

Key Features

• Capacitance & Voltage: 22 µF nominal capacitance at a 25 V rated voltage with tolerance −20% to +20% for predictable filtering and decoupling performance.
• Wide Temperature Range: Specified for operation from −55 °C to +105 °C, enabling use in environments with significant temperature variation.
• Endurance: Rated life of 1000 hours at 105 °C; capacitance, tan δ and leakage meet the specified endurance criteria after the endurance test.
• Ripple Handling: Low‑frequency ripple current 58 mA (120 Hz) and high‑frequency ripple current 116 mA (10 kHz), supporting both power‑supply smoothing and higher‑frequency audio circuits.
• Loss & Leakage: tan δ (DF) of 0.18 measured at 20 °C, 120 Hz, with a measured leakage current of 16.5 µA for controlled dissipation and low standby loss.
• Compact Radial Package: Radial lead can, physical size φ5 × 11 mm (height seated max 11 mm), lead spacing 2.0 mm (±0.5 mm), available in bulk or bag packing for manual or automated assembly flows.
• AEC‑Q200 Qualified: Series rating shown as AEC‑Q200, addressing demanding reliability expectations (refer to manufacturer for qualification details).
• RoHS Compliance (Series): UKT series is noted as compliant to RoHS directives in the series documentation.

Typical Applications

• Audio Equipment: Used for power‑rail decoupling, smoothing and coupling in amplifiers, preamps and other audio signal chains where stable capacitance and low loss at 120 Hz and higher frequencies matter.
• Embedded Power Supplies: Board‑level filtering and bulk decoupling in small form‑factor power modules where a compact radial capacitor is required.
• Industrial Electronics: Temperature‑tolerant filtering components for control and signal circuits that must operate reliably up to 105 °C.

Unique Advantages

• Designed for wide thermal environments: −55 °C to +105 °C rating supports deployment in equipment exposed to broad temperature swings.
• Proven endurance at elevated temperature: 1000 hours at 105 °C provides predictable aging behavior for longer maintenance intervals.
• Compact board footprint: φ5 × 11 mm can size and 2.0 mm lead spacing minimize PCB area while remaining easy to handle and mount.
• Measured low leakage and controlled dissipation: 16.5 µA leakage and tan δ = 0.18 (20 °C, 120 Hz) help maintain signal integrity and reduce standby losses.
• Ripple capability across frequencies: Specified ripple current values at 120 Hz and 10 kHz enable use in both low‑frequency smoothing and higher‑frequency applications.
• Quality and compliance traceability: UKT series documentation lists RoHS compliance and AEC‑Q200 qualification for designs requiring recognized reliability indicators.

Why Choose UKT1E220MDD?

The UKT1E220MDD combines compact radial packaging with performance characteristics tailored to audio and general electronic circuits: stable capacitance, controlled loss, and documented ripple and leakage figures. Its wide −55 °C to +105 °C operating range and 1000‑hour endurance at 105 °C make it a practical choice where thermal robustness and predictable long‑term behavior matter.

This part is suitable for designers and purchasers looking for a small, polarized electrolytic capacitor with clear electrical parameters and reliability indicators (including AEC‑Q200 listed for the series). It delivers the component-level data needed to evaluate board‑level filtering and decoupling tradeoffs while simplifying BOM selection for compact, temperature‑challenging designs.
