UCK1V172MNS1MS

The UCK1V172MNS1MS is a chip-type, low-impedance aluminum electrolytic capacitor from Nichicon's UCK series. It provides 1.7 mF (1700 μF) capacitance at a 35 V rating and is supplied in an SMD radial can package designed for automated assembly.

Targeted for demanding electronics environments, this part combines a wide operating temperature range and long endurance for applications requiring robust bulk energy storage, decoupling and ripple handling in constrained SMD footprints.

Key Features

• Capacitance & Voltage — 1.7 mF (1700 μF) nominal capacitance with a 35 V rated voltage and ±20% tolerance for stable bulk storage and decoupling.
• Low Impedance Design — Chip-type, low-impedance construction to support higher ripple currents and improved AC performance in power circuits.
• Temperature Range & Endurance — Rated for −55 °C to +105 °C with an endurance specification of 5000 hours at 105 °C under rated voltage.
• Ripple Current Capability — Specified ripple current of 1.04 A at 120 Hz and 2.08 A at 10 kHz to support smoothing and decoupling in switching power and DC–DC converter stages.
• Reliability & Automotive Grade — AEC-Q200 qualified for designs requiring automotive-grade componentry; RoHS compliant (2011/65/EU, (EU)2015/863).
• Assembly-Friendly Package — Surface-mount radial can (SMD) format and carrier-tape feed compatibility for automated pick-and-place assembly.
• Leakage & Dissipation Characteristics — Series leakage current spec: after 2 minutes at 20 °C, leakage ≤ 0.01CV or 3 µA (whichever is greater). Tangent of loss angle (tan δ) specified with series guidance for high-capacitance values.
• Size — Compact package size: L: 2.1 cm × D: 1.25 cm suitable for space-constrained board layouts.

Typical Applications

• Automotive Electronics — Bulk energy storage and smoothing in on-board power supplies and DC–DC converters where AEC-Q200 qualification is required.
• Power Supply Filtering — Input/output smoothing and decoupling in switching regulators thanks to low impedance and high ripple current capability.
• Industrial Control — Energy buffering and transient handling in motor control and industrial power modules operating across a wide temperature range.
• Embedded Systems — Board-level decoupling and bulk capacitance for microcontroller and SoC power rails in compact, automated-assembly designs.

Unique Advantages

• High-Temperature Endurance: 5000 hours at 105 °C under rated voltage provides predictable lifetime behavior in hot operating environments.
• Automated Assembly Ready: Carrier-tape feed compatibility and SMD radial can format reduce insertion and handling time in high-volume production.
• Measured Ripple Performance: Specified ripple currents at both 120 Hz and 10 kHz support a range of switching and smoothing requirements without guesswork.
• Automotive-Grade Reliability: AEC-Q200 qualification supports use in designs that demand established automotive component screening.
• RoHS Compliant: Conforms to relevant RoHS directives, simplifying regulatory compliance for end products.
• Defined Electrical Limits: Clear leakage current and tan δ specifications (with series guidance for high-capacitance units) make margining and thermal design straightforward.
