UKT1V221MPD

The UKT1V221MPD is a radial lead aluminum electrolytic capacitor designed for general audio equipment and other electronics that require wide temperature performance. It is a 220 µF, 35 V polarized capacitor in a compact φ8 × 11.5 mm can with 3.5 mm lead spacing.

Engineered for durability and temperature resilience, the part supports an operating range from −55°C to +105°C and a rated endurance of 1000 hours at 105°C, making it suitable for applications needing stable smoothing, decoupling, and energy storage under extended thermal stress.

Key Features

• Capacitance & Voltage: 220 µF rated capacitance at 35 V with a tolerance of −20% to +20%, providing predictable charge storage for power conditioning and decoupling.
• Wide Temperature Range: Specified for −55°C to +105°C operation, supporting designs that encounter broad ambient or thermal conditions.
• Endurance & Reliability: Rated for 1000 hours at 105°C; meets endurance characteristics when restored to 20°C after the life test.
• Ripple Current Performance: Low-frequency ripple current 260 mA at 120 Hz and high-frequency ripple current 390 mA at 10 kHz, with frequency coefficients defined in the UKT series datasheet.
• Loss Angle (tan δ): tan δ of 0.16 measured at 20°C, 120 Hz (typical for 35 V rating), supporting predictable ESR-related behavior in audio circuits.
• Compact Radial Package: φ8 × 11.5 mm can (L: 1.15 cm × D: 0.8 cm) with 3.5 mm lead spacing and bulk/bag packing options for assembly flexibility.
• AEC-Q200 Rating: Rated AEC-Q200 for enhanced quality assurance where that qualification is required.

Typical Applications

• General Audio Equipment: Smoothing and power supply decoupling in audio amplifiers and other audio signal chains, leveraging the UKT series’ focus on audio applications.
• Power Supply Filtering: Bulk and local filtering in DC power rails where 220 µF capacitance and 35 V rating are appropriate for transient suppression and supply stability.
• Decoupling in Electronic Modules: Energy reservoir and decoupling for modules that operate across wide temperatures and require predictable leakage and loss characteristics.

Unique Advantages

• Designed for Wide Temperature Operation: −55°C to +105°C rating supports deployment in environments with large thermal variation without sacrificing performance.
• Long Endurance: 1000 hours at 105°C specification gives designers a clear reliability expectation for elevated-temperature deployments.
• High-Frequency Capability: Specified high-frequency ripple current (390 mA at 10 kHz) and frequency coefficients available from the UKT series help in selecting the part for switching and high-frequency power applications.
• Compact Footprint: φ8 × 11.5 mm can with 3.5 mm lead spacing enables space-efficient designs and straightforward radial mounting.
• Measured Loss and Leakage Data: tan δ of 0.16 (35 V, 120 Hz, 20°C) and measured leakage current figures allow engineers to predict ESR-related heating and standby currents accurately.
• Production Availability: Listed as mass production, supporting predictable sourcing for production volumes.
