UCH1E151MCS1GS

The UCH1E151MCS1GS is a chip-type, high-reliability aluminum electrolytic capacitor from Nichicon’s UCH series. It is a polarized surface-mount capacitor specified at 150 µF and 25 V, engineered for board-level power filtering where stable performance across a wide temperature range is required.

Key value comes from a combination of low-temperature ESR specification, AEC-Q200 qualification, and carrier-tape compatibility for automated placement—making it suitable for demanding embedded and vehicular electronics that require reliable capacitance and controlled ESR from −40 °C to 125 °C.

Key Features

• Capacitance & Voltage — 150 µF rated capacitance at 25 V, with tolerance ±20% (120 Hz, 20 °C).
• Temperature Range — Specified operating temperature from −40 °C to 125 °C for use in wide-temperature environments.
• Low-temperature ESR — ESR characterized with a specific value after −40 °C testing; measured ESR is 300 mΩ at 100 kHz.
• Reliability & Qualification — AEC-Q200 qualified and designed for endurance: 2000 hours at 125 °C with defined limits on capacitance change, tan δ, and leakage current.
• Surface-mount Package — Chip/φ6.3 SMD can package sized L: 7.7 × D: 6.3 mm with recommended land size L: 6.6 × W: 6.6 mm; compatible with carrier-tape feeding for automated placement.
• Soldering Heat Resistance — Meets specified characteristics after exposure to 250 °C hot-plate condition for 30 seconds, supporting standard surface-mount assembly processes.
• Ripple Current Performance — Rated ripple current values include 98.5 mA at 120 Hz and 197 mA at 10 kHz; frequency coefficient table applies across common ripple frequencies.
• RoHS Compliance — Conforms to RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics — AEC-Q200 qualification and −40 °C to 125 °C rating make it suitable for vehicle ECUs and power modules that require reliable bulk capacitance and controlled ESR.
• Board-level Power Filtering — Surface-mount chip can form factor and 150 µF capacitance support decoupling and smoothing on compact PCB power rails.
• Ruggedized Embedded Systems — Long endurance (2000 h at 125 °C) and soldering-heat resistance support use in industrial and harsh-environment electronics.

Unique Advantages

• Qualified Reliability: AEC-Q200 qualification provides documented screening for high-reliability applications.
• Wide Operating Temperature: Guaranteed operation from −40 °C to 125 °C supports deployment across a broad range of thermal environments.
• Low-temperature ESR Characterization: ESR specified after −40 °C testing and a measured ESR of 300 mΩ at 100 kHz help designers manage impedance and stability at low temperatures.
• Surface-mount Compatibility: Chip can package with carrier-tape feed makes the part suitable for automated PCB assembly workflows.
• Endurance under Stress: Endurance rating of 2000 hours at 125 °C with specified limits on capacitance, tan δ, and leakage current supports long-term, high-temperature operation.
• Process-ready: Demonstrated resistance to 250 °C soldering-heat exposure aligns with reflow assembly processes.
