UCZ1C221MCS1GS

The UCZ1C221MCS1GS is a chip‑type aluminum electrolytic capacitor in the Nichicon UCZ series designed for surface‑mount applications requiring high temperature endurance and automotive‑grade reliability. It delivers 220 µF at 16 V in a compact SMD can package and is suitable for automated assembly from carrier tape.

Key strengths include rated operation from −40 °C to +125 °C, an ESR specification verified after low‑temperature testing, and AEC‑Q200 qualification for demanding environments where long life and stable performance are required.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 16 V and ±20% tolerance for bulk decoupling and energy storage in low‑voltage power rails.
• Temperature Range — Rated for operation from −40 °C to +125 °C to support high‑temperature electronics and elevated ambient environments.
• High‑Temperature Endurance — Specified lifetime of 3000 hours at 125 °C, enabling extended operation under thermal stress.
• Low‑Temperature ESR Characterization — ESR performance specified after testing at −40 °C, supporting reliable behavior across the full temperature range.
• ESR & Ripple Current — Equivalent series resistance of 200 mΩ at 100 kHz, with ripple current ratings of 135 mA at 120 Hz and 270 mA at 10 kHz for effective ripple handling.
• Surface‑Mount, Tape‑Fed Package — Chip‑type SMD can suitable for automatic mounting machines fed with carrier tape; package dimensions L: 1.0 × D: 0.8 cm and recommended land size L: 8.3 × W: 8.3 mm.
• Automotive Qualification & Environmental Compliance — AEC‑Q200 qualified and RoHS compliant for regulated manufacturing and automotive use.
• Polarized — Designated polarity for use where polarized electrolytic capacitance is required.

Typical Applications

• Automotive electronic control units (ECUs) — Bulk decoupling and smoothing in power rails where AEC‑Q200 qualification and high‑temperature operation are required.
• Power conversion modules — Energy storage and ripple suppression in DC‑DC converters and power management circuits operating at elevated temperatures.
• Industrial controls — Stable capacitance and ESR across −40 °C to +125 °C for motor controls, drives, and factory automation electronics.
• High‑temperature embedded systems — Compact SMD solution for electronics exposed to sustained high ambient temperatures or high thermal loading.

Unique Advantages

• Designed for high ambient temperature: 3000 hours rated life at 125 °C provides confidence in prolonged high‑temperature operation.
• Automotive‑grade reliability: AEC‑Q200 qualification supports use in safety‑critical and vehicle electronics where rigorous component qualification is required.
• Verified low‑temperature ESR: ESR specified after −40 °C testing ensures predictable performance across the full operating range.
• Compact SMD can for automated assembly: Tape‑fed surface‑mount format and small footprint simplify board layout and high‑volume production.
• Measurable ripple handling: Specified ripple currents at 120 Hz and 10 kHz and 200 mΩ ESR at 100 kHz help engineers size capacitors for known ripple and thermal budgets.
• RoHS compliant: Meets environmental directive requirements for regulated manufacturing environments.
