UCH1H221MCS1GS

The UCH1H221MCS1GS is a chip‑type aluminum electrolytic capacitor designed for high‑reliability applications. It delivers 220 µF at 50 V in a compact surface‑mount, carrier‑tape compatible package and is optimized for demanding temperature and vibration environments.

Key value comes from a low‑temperature ESR specification, AEC‑Q200 qualification, and a rated operating range of −40 °C to 125 °C, making it suitable where stable capacitance, controlled ESR and long life under elevated temperature are required.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance with a 50 V rated voltage and ±20% tolerance, suitable for mid‑voltage power applications.
• Low‑Temperature ESR — Specified ESR behavior with an added ESR specification after the −40 °C test; ESR = 250 mΩ measured at 100 kHz for this part number.
• Wide Temperature Range — Operates from −40 °C to 125 °C, enabling use across harsh thermal environments.
• High Endurance — 2000 hours rated life at 125 °C, with specified limits for capacitance change, tan δ and leakage after endurance testing.
• Ripple Current Capability — Rated ripple current of 200 mA at 120 Hz and 400 mA at 10 kHz (part‑specific frequency coefficients apply).
• Surface‑Mount, Tape Feedable — Chip (radial can SMD) package designed for automatic mounting machines fed with carrier tape; recommended land size L:1.03 × W:1.03 cm.
• Automotive‑Grade Reliability — AEC‑Q200 qualified and RoHS compliant for regulated environments and long‑term reliability requirements.
• Compact Footprint — Part dimensions approximately L:1 × D:1 cm, enabling dense board layouts.
• Polarized Electrolytic — Polarized device suitable for DC decoupling and energy‑storage roles within specified polarity limits.

Typical Applications

• Automotive Electronics — Use in vehicle electronic modules that require AEC‑Q200 qualification and reliable operation from −40 °C to 125 °C.
• Power Supply Filtering — Bulk decoupling and smoothing in mid‑voltage power rails where 220 µF at 50 V and controlled ESR are needed.
• Embedded Power Modules — Local energy storage for compact power converters and modules that require a tape‑feedable SMD capacitor with defined ripple current ratings.

Unique Advantages

• Defined Low‑Temperature Performance: ESR specification includes post‑test data at −40 °C, providing predictable behavior in cold environments.
• AEC‑Q200 Qualification: Explicit qualification for automotive reliability helps reduce validation effort for vehicle electronics designs.
• High Thermal Endurance: 2000 hours at 125 °C rating supports long life where elevated operating temperatures are expected.
• Tape‑Feed SMD Convenience: Compatible with automatic mounting machines fed by carrier tape for efficient high‑volume assembly.
• Measured High‑Frequency ESR: 250 mΩ at 100 kHz gives designers a quantifiable parameter for high‑frequency decoupling and stability analysis.
