UCZ1A331MCS1GS

The UCZ1A331MCS1GS is a chip-type aluminum electrolytic capacitor designed for high-reliability applications requiring elevated operating temperatures. It is a surface-mount, polar capacitor specified for operation from -40 °C to +125 °C and is targeted at demanding systems where long-term endurance and low-temperature ESR behavior matter.

With a nominal capacitance of 330 µF at 10 V, low-temperature ESR characterization, AEC‑Q200 qualification and RoHS compliance, this part is suitable for engineered designs that demand robust power filtering and decoupling across a wide thermal and electrical range.

Key Features

• Capacitance and Voltage — 330 µF nominal capacitance at a 10 V rated voltage, with ±20% tolerance for predictable bulk energy storage and decoupling.
• Wide Operating Temperature — Rated for -40 °C to +125 °C to support high-temperature electronics and environments.
• High‑Temperature Endurance — Rated lifetime of 3000 hours at 125 °C, supporting long-term operation under elevated temperatures.
• Low-Temperature ESR Specification — ESR characterized at low temperatures with added ESR specification after a -40 °C test, helping maintain performance in cold conditions; specified ESR is 150 mΩ at 100 kHz.
• Ripple Current Performance — Specified ripple currents of 250 mA at 120 Hz and 500 mA at 10 kHz for AC stress handling in power circuitry.
• Surface-Mount Chip Package — Chip-type SMD in a radial, can-style package designed for automatic mounting with carrier tape; land size recommendation L: 1.03 × W: 1.03 cm.
• Soldering Heat Resistance — Meets soldering heat resistance criteria (hot plate at 250 °C for 30 seconds) as defined in the series specification.
• AEC‑Q200 Qualified and RoHS Compliant — AEC‑Q200 qualification for automotive-grade reliability and compliance with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics — Bulk filtering and decoupling in control modules and under-hood electronics where AEC‑Q200 qualification and a -40 °C to +125 °C range are required.
• Power Supply Stabilization — DC‑DC converter output filtering and bulk energy storage in compact SMD power stages that must tolerate elevated operating temperatures and ripple currents.
• Industrial Controls — Energy buffering and smoothing in industrial power systems operating in wide temperature ranges and subject to repeated thermal stress.

Unique Advantages

• Engineered for High Temperatures: 3000-hour endurance at 125 °C provides long-term stability for designs exposed to sustained heat.
• Verified Low-Temperature Behavior: Additional ESR specification after -40 °C testing gives designers measurable performance data for cold-start and low-temperature operation.
• SMD-Friendly Package: Chip-type can-style SMD optimized for automatic placement with carrier tape, simplifying assembly in high-volume production.
• Balanced AC Performance: Specified ripple currents at 120 Hz and 10 kHz help ensure reliable performance across common switching and line-frequency conditions.
• Automotive-Grade Reliability: AEC‑Q200 qualification and RoHS compliance support integration into regulated automotive and high-reliability product lines.
