UCZ1H101MCS1GS

The UCZ1H101MCS1GS is a surface-mount, chip-type aluminum electrolytic capacitor from Nichicon’s UCZ series designed for high-temperature operation. It combines a 100 µF, 50 V rating with AEC‑Q200 qualification and a wide operating range of −40 °C to +125 °C for reliable performance in demanding electronic environments.

Intended for automotive and other high-reliability applications, this part delivers low-temperature ESR specification, defined ripple current capability, and extended endurance at elevated temperature, making it suitable for power filtering, decoupling and other on-board power functions.

Key Features

• Capacitance & Voltage — 100 µF rated capacitance at 50 V, with ±20% tolerance at 20 °C (120 Hz).
• Temperature Range & Endurance — Specified for operation from −40 °C to +125 °C with a rated lifetime of 3000 hours at 125 °C.
• Low‑temperature ESR — ESR characterized after −40 °C testing and specified at 200 mΩ measured at 100 kHz for predictable behavior in cold conditions.
• Ripple Current Capability — 250 mA at 120 Hz and 500 mA at 10 kHz, supporting filtering and decoupling in power circuits.
• Automotive Qualification — AEC‑Q200 Qualified to meet automotive stress qualification requirements.
• Assembly & Package — Surface-mount radial can (SMD) chip type supplied in carrier tape for automatic placement; recommended land size 1.03 × 1.03 cm and part footprint approximately 1 × 1 cm.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive power rails — AEC‑Q200 qualification and −40 °C to +125 °C range make this capacitor suitable for vehicle power-supply decoupling and filtering.
• DC–DC converters and power modules — 100 µF at 50 V with defined ripple current and low ESR supports output smoothing and transient handling.
• Industrial high‑temperature electronics — Extended 125 °C endurance (3000 h) provides stable capacitance and leakage performance in elevated-ambient systems.

Unique Advantages

• High-temperature reliability: Rated operation to +125 °C with a 3000‑hour endurance at that temperature provides predictable long-term behavior in hot environments.
• Temperature‑characterized ESR: ESR specified after −40 °C testing and 200 mΩ at 100 kHz reduces uncertainty for designs exposed to wide thermal cycles.
• Automotive-grade qualification: AEC‑Q200 qualification signals suitability for automotive electronics and other applications requiring component-level stress qualification.
• Assembly-friendly format: Chip-type SMD delivered on carrier tape simplifies automated placement and throughput in production lines.
• Defined ripple handling: Separate ripple current ratings at low and high frequencies (120 Hz and 10 kHz) allow designers to match the part to switching and line-frequency conditions.
• Standards compliance: RoHS compliance reduces regulatory risk for modern electronics supply chains.
