UBT1K471MHD8

The UBT1K471MHD8 is an aluminum electrolytic capacitor in a radial can package designed for high‑temperature operation. It delivers 470 µF at 80 V with a polarized radial lead configuration and compact dimensions (L: 2.5 × D: 1.6 cm) for board‑mounted power and control circuits.

Engineered for demanding environments, the part supports an operating temperature range of −40 °C to +125 °C, AEC‑Q200 qualification, and RoHS compliance, making it suitable for automobile electronics and other heavy‑duty applications that require long high‑temperature load life.

Key Features

• Capacitance & Voltage — 470 µF rated capacitance at 80 V provides bulk energy storage suitable for higher‑voltage system rails.
• High‑Temperature Range — Rated for −40 °C to +125 °C for reliable operation in elevated ambient conditions.
• High‑Temperature Lifetime — Specified with a lifetime of 5000 hours at +125 °C for sustained performance under elevated temperature and load; series endurance at +125 °C ranges from 2000 to 10000 hours depending on configuration.
• Automotive Qualification — AEC‑Q200 qualified and explicitly described as suited for automobile electronics where heavy‑duty service is required.
• Electrical Performance — Low impedance of 110 mΩ and specified ripple current handling of 1.005 A at 120 Hz and 1.5 A at 100 kHz for robust ripple handling in power applications.
• Leakage & Loss — Series leakage characteristic: after 1 minute at rated voltage and 20 °C leakage current is ≤ 0.03CV (µA); tangent of loss angle (tan δ) for 80 V rating is specified at 0.08 (120 Hz, 20 °C).
• Package & Mounting — Radial lead, can style with 7.5 mm lead spacing for through‑hole mounting and mechanical robustness.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics — Suited for automobile electronics and control modules that demand AEC‑Q200 qualification and reliable operation up to +125 °C.
• High‑Temperature Power Systems — Applicable where board‑mounted capacitors must sustain elevated ambient temperatures and continuous ripple currents.
• Rugged Industrial Controls — Useful in heavy‑duty industrial equipment and control electronics requiring durable electrolytic bulk capacitance in harsh environments.

Unique Advantages

• AEC‑Q200 Qualified: Enables use in automotive and similarly stringent environments where component qualification is required.
• Wide Operating Temperature: −40 °C to +125 °C rating supports designs exposed to extreme thermal conditions without derating the component choice.
• Proven High‑Temperature Endurance: 5000 hours at +125 °C for this part (series endurance shown from 2000 to 10000 hours) provides predictable long‑term performance under load.
• High Ripple Capability: Rated ripple currents of 1.005 A (120 Hz) and 1.5 A (100 kHz) combined with a low impedance of 110 mΩ reduce heating and improve stability in power applications.
• Compact Radial Can Packaging: 7.5 mm lead spacing and can form factor simplify through‑hole mounting and mechanical retention in robust assemblies.
• RoHS Compliance: Meets current RoHS requirements for environmental and regulatory alignment.
