UBT2A100MPD

The UBT2A100MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UBT series designed for high-temperature operation. It delivers 10 µF capacitance at 100 V with polarized radial-lead construction and is intended for demanding electronics that require stable capacitive performance under elevated temperature and ripple conditions.

Targeted use cases include automobile electronics and other high-temperature applications where AEC‑Q200 qualification, extended endurance, and controlled leakage and ripple characteristics are required.

Key Features

• Capacitance & Voltage: 10 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance, suitable for DC decoupling and energy storage at elevated voltages.
• High-temperature Endurance: Rated for operation from −40°C to +125°C with a lifetime/endurance of 2000 hours at +125°C for the specified case size.
• Ripple Current Performance: Specified ripple capability of 100.5 mA at 120 Hz (low frequency) and 150 mA at 100 kHz (high frequency), supporting AC ripple handling in power circuits.
• Low Leakage Current: Leakage current specified at 30 µA (per series leakage formula), helping preserve charge and reduce standby losses in long-term applications.
• Package & Mounting: Radial, can-style package (φ8×11.5L) with 3.5 mm lead spacing and bulk/no terminal forming—designed for through-hole assembly and robust mechanical mounting.
• Quality & Compliance: AEC‑Q200 rated and RoHS compliant, aligning with high-reliability automotive and industrial requirements.

Typical Applications

• Automotive electronics: Intended for automobile electronics where +125°C endurance and AEC‑Q200 qualification are required for reliable long-term operation.
• On-board power filtering: Use in power-supply smoothing and decoupling tasks where the 100 V rating and specified ripple current capability are needed.
• High-temperature modules: Suitable for electronic modules that operate in elevated ambient temperatures, leveraging the −40°C to +125°C operating range and 2000 h endurance at 125°C.

Unique Advantages

• Designed for elevated temperatures: Endurance specification of 2000 hours at +125°C supports deployment in high-temperature environments.
• AEC‑Q200 qualification: Provides a documented reliability pedigree for applications that require automotive-grade components.
• Measured ripple capability: Published ripple current values at both low and high frequencies (100.5 mA at 120 Hz; 150 mA at 100 kHz) enable confident selection for ripple-demanding circuits.
• Low leakage: Specified 30 µA leakage current consistent with the series leakage formula, aiding in hold-up and low-current designs.
• Compact radial can: φ8×11.5L radial package with 3.5 mm lead spacing fits through-hole assemblies where board-level robustness is required.
• RoHS compliant: Meets RoHS directive requirements for environmental compliance.
