UCX1V101MCS1GS

The UCX1V101MCS1GS is a chip-type aluminum electrolytic capacitor designed for high-temperature operation and automatic PCB assembly. It delivers 100 µF at 35 V in a compact surface-mount radial can package from Nichicon, with construction and specs aimed at demanding thermal and environmental conditions.

Key value propositions include guaranteed operation across −40 °C to +135 °C, AEC‑Q200 qualification for automotive-grade reliability, a specified ESR after low-temperature testing, and RoHS compliance for environmental requirements.

Key Features

• Temperature range & Endurance – Rated for −40 °C to +135 °C with an endurance specification of 2000 hours at 135 °C, supporting high‑temperature system designs.
• Electrical performance – 100 µF nominal capacitance at a rated voltage of 35 V with ±20% tolerance (measured at 120 Hz, 20 °C).
• ESR specification – ESR specified as 200 mΩ at 100 kHz, with an added ESR requirement after testing at −40 °C to ensure low-temperature performance.
• Ripple current capability – Rated ripple currents of 135 mA at 120 Hz (low frequency) and 270 mA at 10 kHz (high frequency) for power-conditioning use.
• Package & mounting – Surface mount radial can designed for automatic mounting with carrier tape; nominal component footprint L: 10 mm × D: 8 mm and recommended PCB land size 8.3 mm × 8.3 mm.
• Polarity & tolerance – Polarized aluminum electrolytic construction with standard ±20% capacitance tolerance.
• Compliance & qualification – AEC‑Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulated and automotive applications.

Typical Applications

• Automotive electronics – Bulk and decoupling capacitor for modules that must tolerate elevated operating temperatures and meet AEC‑Q200 requirements.
• Power electronics – DC bus smoothing and local energy storage in compact power supplies where temperature endurance and defined ESR are required.
• Industrial control – High‑temperature controllers and modules that undergo elevated thermal stress and require long-term stability.

Unique Advantages

• High-temperature endurance: 2000 hours rated life at 135 °C enables use in sustained high-temperature environments without sacrificing capacitance stability.
• Low-temperature performance verification: ESR specified after −40 °C testing provides predictable behavior across the full −40 °C to +135 °C range.
• Automated assembly ready: Designed for carrier-tape feeding and surface-mount placement to streamline pick-and-place production flows.
• Automotive-grade qualification: AEC‑Q200 qualification supports integration into vehicle systems that require proven component reliability.
• Compact footprint: Small can size with a defined PCB land pattern (8.3 mm × 8.3 mm) suits space-constrained board designs.
• Regulatory compliance: RoHS compliant to support regional environmental requirements.
