UBT2A101MHD

The UBT2A101MHD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UBT series, specified at 100 µF and a 100 V rating. Designed for applications requiring high-temperature endurance and dependable performance, this polarized can-style capacitor is built for heavy-duty operating environments.

Key use cases include power-supply filtering and energy smoothing where elevated temperature capability, voltage handling and stable ripple performance are required. The device combines a compact φ12.5 × 20 mm package and AEC‑Q200 qualification for demanding applications.

Key Features

• Capacitance and Tolerance — 100 µF nominal capacitance with ±20% tolerance (120 Hz, 20°C) for predictable filtering and decoupling performance.
• Voltage Rating — 100 V rated voltage suitable for higher-voltage rail filtering and energy storage tasks.
• High-Temperature Endurance — Rated for operation from –40°C to 125°C with a specified life of 5000 hours at 125°C, supporting long-term operation under elevated thermal stress.
• Ripple Current Handling — Specified low-frequency ripple current of 663.3 mA (120 Hz) and high-frequency ripple current of 990 mA (100 kHz) to support load-induced AC ripple in power supplies.
• Low Leakage — Leakage current specified at 300 µA to minimize quiescent losses and support stable voltage retention.
• Package and Mounting — Radial lead can (φ12.5 × 20 mm) with 5 mm lead spacing (±0.5 mm), available bulk or bag packing for through-hole assembly.
• Quality and Compliance — AEC‑Q200 qualification and RoHS compliance for use in regulated and reliability-focused designs.

Typical Applications

• Automotive Electronics — Suited for automotive electronic modules where high-temperature endurance and AEC‑Q200 qualification are required for power-supply smoothing and transient handling.
• Power Supply Filtering — Filtering and bulk energy storage on mid- to high-voltage rails, leveraging the 100 V rating and high ripple-current capability.
• Industrial Power Electronics — Decoupling and smoothing in industrial controllers and power converters that operate at elevated temperatures.

Unique Advantages

• High-temperature reliability: Rated for –40° to 125°C with a 5000-hour life at 125°C, enabling sustained operation in thermally stressed environments.
• AEC‑Q200 qualified: Meets automotive-grade reliability requirements for designs that demand documented component robustness.
• Strong ripple performance: Dual ripple-current specifications (663.3 mA at 120 Hz and 990 mA at 100 kHz) provide headroom for both low- and high-frequency ripple conditions.
• Compact, through-hole form: φ12.5 × 20 mm radial can with 5 mm lead spacing offers a compact footprint for robust mechanical mounting and easy prototyping or production assembly.
• Low leakage: 300 µA leakage current helps maintain low quiescent losses and reliable voltage stability over time.
• Regulatory compliance: RoHS-compliant materials reduce regulatory risk for commercial and industrial products.
