UCH1V221MCL1GS

The UCH1V221MCL1GS is a chip-type aluminum electrolytic capacitor designed for high-reliability surface-mount applications. It combines a compact radial can SMD package with specifications tuned for stable performance across a wide temperature range.

Intended for automated surface-mount assembly and applications requiring extended high-temperature endurance, this part targets demanding electronics markets including automotive systems where AEC-Q200 qualification and RoHS compliance are required.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 35 V and a tolerance of ±20% (at 120 Hz, 20°C).
• Temperature Range — Rated to operate from −40°C to +125°C to support high-temperature environments.
• Low-temperature ESR Specification — ESR specified after −40°C testing with an equivalent series resistance of 200 mΩ at 100 kHz for predictable performance at low temperatures.
• Ripple Current Capability — 135 mA at 120 Hz and 270 mA at 10 kHz to support smoothing and decoupling across common frequency bands.
• High-Temperature Endurance — Designed for 2000 hours at 125°C, with specified limits for capacitance change, tan δ, and leakage current after endurance testing.
• Surface-Mount Assembly — Chip-type radial can (SMD) package sized L: 1.0 × D: 0.8 cm with recommended land pattern 8.3 × 8.3 mm; suitable for carrier-tape automated placement.
• Reliability & Compliance — AEC-Q200 qualified and RoHS compliant to support regulated, safety-focused designs.
• Polarized Design — Polarized electrolytic capacitor with black top-case marking for polarity identification.

Typical Applications

• Automotive Electronics — Power smoothing and decoupling in electronic control modules and other vehicle systems where AEC-Q200 qualification is required.
• Power Supply Filtering — Bulk decoupling and ripple suppression in compact SMD power regulators and DC–DC converter outputs.
• Industrial Electronics — High-temperature, long-life filtering in controllers and instrumentation operating up to 125°C.

Unique Advantages

• Proven High-Temperature Endurance: 2000 hours at 125°C provides a measurable reliability baseline for long-life designs.
• Low-Temperature ESR Stability: ESR characterized after −40°C testing ensures predictable behavior in cold-start and low-temperature operating conditions.
• Surface-Mount Ready: Carrier-tape compatible chip package simplifies automated assembly and reduces handling steps in production.
• Frequency-aware Ripple Performance: Specified ripple currents at 120 Hz and 10 kHz enable designers to size the capacitor according to expected operating frequencies.
• Regulatory and Quality Compliance: AEC-Q200 qualification and RoHS compliance support use in regulated environments and simplify validation requirements.
