UKT1H221MPD

The UKT1H221MPD is a radial-lead aluminum electrolytic capacitor designed for general audio equipment and other applications requiring wide temperature range operation. It delivers 220 µF capacitance at 50 V in a compact φ10 × 12.5 mm can with 5.0 mm lead spacing.

Engineered for reliable filtering and decoupling in audio systems, the UKT1H221MPD combines a broad operating temperature range, defined ripple current ratings, and a 1000 hour endurance at 105 °C to support stable long-term performance in demanding environments.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 50 V, tolerance ±20% (measured at 120 Hz, 20 °C).
• Wide Temperature Range — Specified operating range from −55 °C to 105 °C for reliable operation across challenging ambient conditions.
• Endurance — 1000 hours at 105 °C with capacitance change within ±20% and tan δ within 200% of initial specified value after the test.
• Loss Angle (tan δ) — Low dissipation factor of 0.14 (measured at 20 °C, 120 Hz) for the 50 V rating, supporting low-loss performance.
• Ripple Current Capability — Low-frequency ripple current 300 mA (120 Hz) and high-frequency ripple current 450 mA (10 kHz), enabling effective smoothing in power paths.
• Leakage Current — Specified leakage current of 330 µA, supporting stable bias and low quiescent loss.
• Compact Radial Package — φ10 × 12.5 mm aluminum can with 5.0 mm lead spacing and radial leads for through-hole assembly and prototyping ease.
• AEC Qualification — Ratings include AEC-Q200, indicating conformance to industry stress test requirements for passive components.

Typical Applications

• Audio Equipment — Designed for general audio systems: power-supply smoothing, decoupling, and energy storage supporting amplifier and preamplifier stages.
• Power Filtering in Consumer Electronics — Compact radial package and defined ripple current ratings make it suitable for local power filtering in compact audio modules and related electronics.
• Temperature-Variable Environments — Use in equipment operating across a wide ambient temperature range (−55 °C to 105 °C) where stable capacitance and endurance are required.

Unique Advantages

• Wide Operating Temperature: −55 °C to 105 °C rating ensures reliable performance in both low- and high-temperature environments.
• Defined Endurance: 1000 hours at 105 °C provides predictable life characteristics for thermal stress planning and reliability projections.
• Balanced Ripple Performance: Dual ripple current specifications (300 mA at 120 Hz, 450 mA at 10 kHz) support both low- and high-frequency filtering needs.
• Low Dissipation Factor: tan δ = 0.14 at 50 V (120 Hz, 20 °C) reduces losses in audio signal and power paths.
• Compact Through-Hole Form Factor: φ10 × 12.5 mm can and 5.0 mm lead spacing deliver space-efficient placement with straightforward radial-lead assembly.
• AEC-Q200 Rated: Conformance to AEC-Q200 testing provides a standardized baseline for component stress qualification.
