UBT1H221MPD8

The UBT1H221MPD8 is a radial-lead aluminum electrolytic capacitor offering 220 µF capacitance at a 50 V rating. Designed for high-temperature operation, this component provides polarized energy storage in a compact φ10×20 mm can with 5 mm lead spacing.

Targeted for demanding power and control electronics, the device combines low impedance, defined ripple-current capability at both low and high frequencies, and AEC-Q200 qualification for use where extended high-temperature endurance and reliability are required.

Key Features

• Capacitance & Tolerance — 220 µF nominal with ±20% tolerance at 120 Hz, 20°C for predictable decoupling and smoothing performance.
• Rated Voltage — 50 V DC rating suitable for many power rails and intermediate bus applications.
• Temperature Range & Endurance — Operating range −40°C to +125°C with a rated lifetime of 5000 hours at 125°C, enabling extended operation in high-temperature environments.
• Ripple Current Capability — Low-frequency ripple current 623.1 mA at 120 Hz and high-frequency ripple current 930 mA at 100 kHz for effective handling of both line- and switching-induced ripple.
• Low Impedance — 98 mΩ impedance to minimize voltage drop and heat generation in high-current applications.
• Leakage Current — Specified leakage current of 330 µA to support predictable standby and bias behavior.
• Package & Mounting — Radial lead can (φ10×20L) with 5 mm lead spacing (±0.5 mm) for through-hole mounting and robust mechanical connection.
• Quality & Compliance — AEC-Q200 qualified and RoHS compliant, supporting designs that require automotive-grade reliability and environmental compliance.
• Packaging & Availability — Supplied in bulk or bag packing with mass-production status for ease of procurement and assembly planning.

Typical Applications

• Power Supply Filtering — Smoothing and decoupling on 50 V rails in power supplies and intermediate bus converters where low impedance and defined ripple handling are needed.
• DC/DC Converter Output — Bulk and output capacitance for switching regulators, benefiting from the capacitor’s high ripple-current capability at switching frequencies.
• Automotive Electronics — Energy storage and decoupling in automotive control modules and electronic subsystems, leveraging AEC-Q200 qualification and high-temperature endurance.
• Industrial Control — Filtering and hold-up in motor drives, sensors, and control boards that operate across −40°C to +125°C.

Unique Advantages

• High-temperature endurance: Rated for 5000 hours at 125°C, enabling longer service life in high-thermal-stress environments.
• AEC-Q200 qualification: Provides a documented level of reliability suitable for automotive and similarly demanding applications.
• Dual-frequency ripple performance: Explicit low- and high-frequency ripple current ratings (623.1 mA at 120 Hz, 930 mA at 100 kHz) to address both mains and switching noise.
• Compact through-hole package: φ10×20 mm radial can with 5 mm lead spacing offers a small footprint while preserving robust mechanical mounting.
• Low impedance: 98 mΩ impedance reduces ESR-related losses and improves voltage stability under load.
• Regulatory compliance: RoHS conformity supports environmentally regulated product designs.
