UBT1H102MHD

The UBT1H102MHD is a radial-lead aluminum electrolytic capacitor offering 1000 µF capacitance at a 50 V rating in a compact φ16 × 30.5 mm can. It is designed for high-temperature, heavy-duty environments with an operating range from −40°C to +125°C and an endurance rating up to 10,000 hours at 125°C.

This part delivers high ripple-current capability and proven reliability (AEC-Q200), making it suitable for demanding power-smoothing and high-temperature applications where long life and robust performance are required.

Key Features

• Capacitance & Voltage — 1000 µF nominal capacitance with ±20% tolerance at 50 V rated voltage for energy storage and bulk decoupling.
• High-Temperature Endurance — Rated to operate from −40°C to +125°C with a rated life of 10,000 hours at 125°C (for φ12.5 mm and larger can sizes), supporting sustained elevated-temperature use.
• Ripple Current Handling — Low-frequency ripple current 1.628 A (120 Hz) and high-frequency ripple current 2.43 A (100 kHz) to support power rail filtering across a broad frequency range.
• Leakage & Polarization — Polarized aluminum electrolytic construction with specified leakage current of 1500 µA.
• Form Factor & Mounting — Radial lead can (φ16 × 30.5 mm) with 7.5 mm lead spacing for through-hole mounting and straightforward PCB placement.
• Compliance & Reliability — AEC-Q200 rating and RoHS-compliant materials for applications requiring recognized reliability and environmental compliance.
• Packaging Options — Available in bulk (no terminal forming) and bag packing to accommodate production and prototyping workflows.

Typical Applications

• Automotive Electronic Control Units (ECUs) — Bulk energy storage and smoothing in high-temperature in-vehicle electronics, leveraging AEC-Q200 qualification and long life at +125°C.
• Power Supply Filtering — DC rail decoupling and power smoothing where high ripple current and large capacitance are needed to stabilize voltages.
• High-Temperature Power Modules — Support for power electronics and modules operating in elevated ambient temperatures, with endurance specified at 125°C.

Unique Advantages

• Long-term high-temperature reliability: 10,000-hour endurance at 125°C (for appropriate can sizes) provides predictable lifetime in elevated-temperature designs.
• High ripple capability across frequencies: Specified ripple currents at both 120 Hz and 100 kHz allow designers to size capacitance for low- and high-frequency filtering requirements.
• AEC-Q200 qualification: Recognized component-level reliability for applications that require automotive-grade qualification and traceable standards.
• Compact radial can packaging: φ16 × 30.5 mm size with 7.5 mm lead spacing delivers substantial capacitance in a space-efficient through-hole form factor.
• RoHS compliance: Materials meet RoHS requirements for environmental compliance in modern assemblies.
• Flexible ordering options: Bulk and bag packing accommodate both production runs and lab/prototyping needs.
