The UBT2A100MPD8 is a radial-lead aluminum electrolytic capacitor in Nichicon’s UBT series designed for high-temperature, heavy-duty applications. It delivers 10 µF at 100 V in a compact φ8 × 11.5 mm can, with AEC‑Q200 qualification and RoHS compliance for use in demanding electronic environments.

Engineered for durability at elevated temperatures, this part offers a 2000-hour endurance rating at 125°C, low loss characteristics, and measurable ripple/current handling suitable for systems where reliability under thermal stress is required.

Key Features

• Capacitance & Voltage — 10 µF rated capacitance at 100 V with ±20% tolerance, optimized for DC bus and power rail applications requiring compact energy storage.
• High-Temperature Endurance — Rated operating temperature range from −40°C to +125°C with a specified life of 2000 hours at 125°C for the φ8 size and 63–100 V range.
• Low Loss / Impedance — Tangent of loss angle (tan δ) of 0.08 at 20°C and 120 Hz and an impedance of 1.5 Ω, supporting efficient operation with reduced heating under AC ripple.
• Ripple Current Capability — 100.5 mA at 120 Hz (low frequency) and 150 mA at 100 kHz (high frequency) to handle ripple and transient currents in power circuits.
• Low Leakage & Polarized Design — Leakage current specified at 30 µA after 1 minute at rated voltage and marked polarization for correct installation.
• Compact Radial Package — φ8 × 11.5 mm can with 3.5 mm lead spacing, radial lead mounting; supplied in bulk/bag packing for straightforward through-hole assembly.
• Industry Reliability — AEC‑Q200 qualified and RoHS compliant for use in regulated, high-reliability environments.

Typical Applications

• Automotive Electronics — Suited for automobile electronics where heavy-duty service and high-temperature endurance are required, backed by AEC‑Q200 qualification.
• High-Temperature Modules — Components and assemblies operating up to +125°C, leveraging the 2000-hour endurance rating at elevated temperature.
• Power Filtering and Ripple Management — Use in circuits requiring defined ripple-current handling (100.5 mA at 120 Hz, 150 mA at 100 kHz) and low tan δ for stable filtering performance.

Unique Advantages

• Proven high-temperature endurance — Rated for 2000 hours at 125°C (φ8, 63–100 V), providing predictable long-term behavior in thermal-stressed designs.
• Qualification for demanding applications — AEC‑Q200 qualification supports deployment in environments with strict reliability expectations.
• Compact footprint — φ8 × 11.5 mm can with 3.5 mm lead spacing delivers required capacitance and voltage in a small through-hole package.
• Measurable ripple and loss performance — Specified ripple currents and a low tan δ (0.08 at 20°C/120 Hz) help control heating and maintain efficiency.
• Low leakage current — 30 µA leakage after 1 minute at rated voltage helps preserve circuit biasing and minimize standby loss.
• RoHS compliant — Conforms to RoHS directives for environmental and regulatory compliance.
