UCD1K101MNS1MS

The UCD1K101MNS1MS is a surface-mount, chip‑type aluminum electrolytic capacitor delivering 100 µF of capacitance at an 80 V rating. It is designed as a low‑impedance SMD solution for high‑density printed circuit boards and automated assembly.

Targeted for demanding environments, this part combines an extended operating temperature range of -55 °C to 105 °C, long endurance (5000 hours at 105 °C), and AEC‑Q200 qualification with RoHS compliance to address reliability and regulatory requirements in industrial and automotive power electronics.

Key Features

• Core Performance — 100 µF capacitance with ±20% tolerance and low tangent of loss angle (tan δ ≤ 0.08 at 80 V, 120 Hz, 20 °C) for stable AC behavior.
• Voltage & Ripple Handling — Rated for 80 V with specified ripple current capability of 250 mA at 120 Hz (low frequency) and 500 mA at 10 kHz (high frequency), supporting bulk smoothing and filtering tasks.
• Thermal and Lifetime — Operating range from -55 °C to 105 °C and an endurance rating of 5000 hours at 105 °C for sustained high‑temperature performance.
• Low Leakage — Leakage current specified at 80 µA, enabling predictable standby and idle behavior in power rails.
• Package & Mounting — Chip‑type radial can in an SMD package (φ12.5 × 13.5L) designed for surface mounting; supplied in embossed carrier taping compatible with automated placement.
• Quality & Compliance — AEC‑Q200 qualified and RoHS compliant for regulated and reliability‑sensitive applications.

Typical Applications

• Automotive power modules — AEC‑Q200 qualification, 80 V rating and robust ripple-current capability make it suitable for power smoothing and energy storage in automotive electronic modules.
• DC–DC converter filtering — 100 µF capacitance and low impedance help reduce output ripple and stabilize converter outputs in high‑voltage designs.
• High‑density SMD power boards — Chip‑type SMD package and embossed carrier taping enable placement on compact, automated assemblies where board space and pick‑and‑place compatibility are important.
