UCX1E221MCS1GS

The UCX1E221MCS1GS is a chip‑type aluminum electrolytic capacitor engineered for high‑temperature operation and automated surface‑mount assembly. It delivers 220 µF at 25 V in a compact radial SMD can designed for environments that require extended thermal endurance and defined ESR behavior at low temperature.

Targeted use cases include automotive and other thermal‑challenged electronics where AEC‑Q200 qualification, wide operating temperature range, and assembly compatibility are required.

Key Features

• Temperature Range & Endurance Rated for operation from −40 °C to +135 °C with an endurance specification of 2000 hours at +135 °C.
• AEC‑Q200 Qualified Meets AEC‑Q200 qualification requirements for designs that require automotive‑grade components.
• Capacitance & Voltage 220 µF nominal capacitance with a rated voltage of 25 V and tolerance of −20% to +20%.
• Low‑temperature ESR Specification ESR specified at 150 mΩ measured at 100 kHz, including an ESR specification after the −40 °C test.
• High Ripple Handling Ripple current ratings of 250 mA at 120 Hz and 500 mA at 10 kHz for demanding power conditions.
• Surface‑mount Can Package Chip‑type radial can SMD package sized 1 × 1 cm, designed for carrier‑tape feed and automatic placement.
• RoHS Compliant Conforms to RoHS directive requirements (2011/65/EU, (EU)2015/863).
• Polarized Design Polarized aluminum electrolytic configuration for standard DC power applications.

Typical Applications

• Automotive Electronics — AEC‑Q200 qualification and a −40 °C to +135 °C rating support use in automotive electronic modules that demand high‑temperature reliability.
• Thermal‑challenged Electronics — Continuous operation and endurance data at +135 °C make this part suitable for electronic systems exposed to elevated temperatures.
• Automated Surface‑mount Assembly — Compatible with carrier tape feeding for placement by automatic mounting machines, improving manufacturability on high‑volume lines.
• Compact SMD Power Modules — 220 µF at 25 V in a 1 × 1 cm SMD can with a 150 mΩ ESR (100 kHz) provides a space‑efficient filter/energy‑storage option for compact power assemblies.

Unique Advantages

• Automotive‑grade Reliability: AEC‑Q200 qualification supports designs that require industry‑recognized component qualification.
• High‑temperature Endurance: 2000 hours rated at +135 °C provides quantified lifetime performance in elevated temperature environments.
