The UCK1E172MNJ1MS is a chip-type, low-impedance aluminum electrolytic capacitor in a surface-mount radial can package. It delivers 1.7 mF (1700 µF) capacitance at a 25 V rating with polarized terminals and is designed for automated placement from carrier tape.

Targeted at automotive and industrial electronics, this part combines wide operating temperature range (−55 °C to +105 °C), AEC-Q200 qualification, and RoHS compliance to support designs requiring long-term reliability and elevated-temperature endurance.

Key Features

• Capacitance and Voltage — 1.7 mF (1700 µF) nominal capacitance with a 25 V rated voltage and ±20% tolerance.
• Low Impedance Chip Type — Chip-type construction optimized for low impedance characteristics suitable for high-reliability power applications.
• Surface-Mount Radial Can Packaging — Surface mount, radial can SMD package intended for automatic mounting machines fed with carrier tape; package case described as Radial, Can - SMD.
• Temperature and Endurance — Rated operating range −55 °C to +105 °C with endurance verified to 5000 hours at 105 °C.
• Ripple Current Ratings — 710 mA at 120 Hz (low frequency) and 1.42 A at 10 kHz (high frequency) to support varying ripple environments.
• Leakage and Dissipation — Series datasheet specifies leakage current after 2 minutes at rated voltage is ≤ 0.01 C V or 3 µA (whichever is greater); tan δ specifications available per rated voltage.
• Qualification and Compliance — AEC-Q200 qualified for automotive-grade reliability and compliant to the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Footprint — Component dimensions L: 1.35 cm × D: 1.25 cm (13.5 mm × 12.5 mm) with recommended surface-mount land size approximately 1.28 cm × 1.28 cm (12.8 mm × 12.8 mm).

Typical Applications

• Automotive Electronics — Suitable for automotive electronic modules where AEC-Q200 qualification and wide temperature range are required.
• Power Supply Modules — Use in surface-mount power subsystems that require bulk capacitance and specified ripple current handling at 120 Hz and 10 kHz.
• Industrial Control — Applicable to industrial control units and embedded systems that demand long-duration endurance at elevated temperatures (5000 hours at 105 °C).
