UBW1K471MHD

The UBW1K471MHD is a radial-lead aluminum electrolytic capacitor designed for high-temperature, long-life power applications. It provides 470 µF capacitance at an 80 V rating in a compact φ16 × 25 mm can with radial leads and 7.5 mm lead spacing.

Engineered for demanding environments, this part combines high ripple current capability, low impedance, and AEC‑Q200 rating to serve engineers working on automotive and other high-reliability power systems requiring sustained performance up to +135°C.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a rated voltage of 80 V and tolerance of ±20% (–20%~20%).
• High‑Temperature Endurance — Rated to operate from –55°C to +135°C with endurance specified at 3000 hours at +135°C.
• Ripple Current Handling — Supports 1.005 A low-frequency ripple at 120 Hz and 1.5 A high-frequency ripple at 10 kHz to address bulk filtering and power-conditioning needs.
• Low Impedance & Loss — 110 mΩ impedance and tanδ of 0.08 (measured at 20°C, 120 Hz) for improved transient response and reduced power loss.
• Leakage Current — Leakage current up to 1128 µA (calculated per 0.03CV at 20°C after 1 minute), consistent with datasheet test conditions.
• Package & Mounting — Radial, can-style package (φ16 × 25 mm), lead spacing 7.5 mm (±0.5 mm), available in bulk or bag packing for through-hole assembly.
• Automotive Qualification — AEC‑Q200 rating specified in product data for use in automotive-grade designs.

Typical Applications

• Automotive power electronics — Bulk energy storage and smoothing in automotive control modules and power subsystems that require AEC‑Q200 qualification and high-temperature endurance.
• High-voltage DC filtering — 80 V rating makes it suitable for DC link and intermediate bus filtering in 48 V / 60 V class power systems.
• Harsh-environment electronics — Long life at +135°C and wide operating temperature range support power conditioning in systems exposed to elevated ambient temperatures.
• Through-hole power assemblies — Radial lead form and compact φ16 × 25 mm can fit densely packed boards and through-hole power modules requiring robust bulk capacitance.

Unique Advantages

• High-temperature rated: Specified for operation to +135°C with a 3000-hour endurance rating, enabling extended service in hot environments.
• Automotive-ready qualification: AEC‑Q200 rating supports integration into automotive-grade designs that require recognized component reliability standards.
• Strong ripple tolerance: Combined low-frequency and high-frequency ripple current ratings (1.005 A @120 Hz, 1.5 A @10 kHz) help manage thermal rise and extend service life under AC stress.
• Low impedance and controlled losses: 110 mΩ impedance and tanδ = 0.08 (120 Hz, 20°C) deliver improved voltage stability and reduced dissipation in power applications.
• Compact radial form factor: φ16 × 25 mm can with 7.5 mm lead spacing provides a high-capacitance, through-hole option for space-constrained power assemblies.
• Production-ready supply: Listed as mass production and available in bulk/bag packing to support production and prototyping workflows.
