UCH1V221MCS1GS

The UCH1V221MCS1GS is a chip‑type aluminum electrolytic capacitor designed for high‑reliability, surface‑mount applications. It delivers 220 µF at 35 V in an SMD can package with polarization suitable for power filtering and bulk energy storage in systems that require extended operation up to 125°C.

Targeted at automotive and other demanding electronics, the device combines AEC‑Q200 qualification, RoHS compliance, and low‑temperature ESR characterization to support automated assembly and reliable operation across −40°C to 125°C.

Key Features

• Electrical Performance — 220 µF nominal capacitance at 35 V with ±20% tolerance; leakage current specified as not more than 0.01CV (µA) after 2 minutes at 20°C.
• Low‑Temperature ESR — ESR characterized down to −40°C; additional ESR specification provided after −40°C testing to support performance in cold environments.
• Ripple Current Capability — Rated ripple currents of 135 mA at 120 Hz and 270 mA at 10 kHz; ESR specified as 200 mΩ at 100 kHz for high‑frequency behavior.
• Reliability & Endurance — AEC‑Q200 qualified with endurance rating of 2000 hours at 125°C; meets specified capacitance, tan δ and leakage criteria after endurance testing.
• Package & Mounting — Surface‑mount can package with a recommended land pattern of 8.3 × 8.3 mm; compatible with automated placement from carrier tape.
• Environmental Compliance — RoHS compliant (2011/65/EU,(EU)2015/863) with black top marking for polarity identification.
• Operating Range — Rated for operation from −40°C to 125°C, supporting designs exposed to wide temperature swings.

Typical Applications

• Automotive electronics — AEC‑Q200 qualification and wide temperature range make this capacitor suitable for automotive power subsystems and electronic control modules that require durable SMD electrolytic capacitance.
• Surface‑mount power modules — Designed for automated assembly (carrier tape compatible) and SMD can packaging for decoupling and bulk storage in compact power boards.
• High‑temperature electronics — Endurance rating at 125°C and low‑temperature ESR data support use in systems exposed to elevated operating temperatures.

Unique Advantages

• AEC‑Q200 Qualified: Enables specification into automotive and other high‑reliability designs that require industry qualification.
• Low‑temperature ESR characterization: Provides verified ESR behavior down to −40°C, reducing uncertainty in cold‑start and low‑temperature operation.
• High‑temperature endurance: 2000 hours at 125°C supports long service life in high‑temperature applications and power‑dense designs.
• Automated assembly ready: Carrier tape compatibility and SMD can packaging simplify pick‑and‑place integration and reduce manual handling.
• Measured high‑frequency performance: Specified 200 mΩ ESR at 100 kHz and published ripple currents at 120 Hz and 10 kHz for predictable filtering behavior across frequencies.
• Regulatory compliance: RoHS conformity supports use in regulated designs and markets requiring restricted substance compliance.
