UBW1A471MPD

The UBW1A471MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UBW series engineered for high-temperature, long-life duty. It delivers 470 µF at 10 V in a compact φ10 × 12.5 mm can with 5 mm lead spacing, optimized for demanding environments.

Designed for automotive and other high-reliability applications, this component combines high temperature endurance (−55°C to +135°C) with AEC-Q200 rating and performance characteristics tuned for power filtering, decoupling, and ripple handling in harsh conditions.

Key Features

• Capacitance & Voltage — 470 µF rated capacitance at 10 V with ±20% tolerance, suitable for bulk energy storage and decoupling tasks.
• High Temperature, Long Life — Specified for operation from −55°C to +135°C with a lifetime of 2000 hours at 135°C (φ10 case), enabling sustained performance in elevated-temperature systems.
• Automotive-Grade Reliability — AEC-Q200 rating and explicit application listing for automotive use support integration into vehicle electronics and other high-reliability systems.
• Low Impedance & Loss — Low impedance (100 mOhm) and tan δ of 0.20 at rated conditions, helping maintain stable voltage filtering and reducing loss under load.
• Leakage Current — Specified leakage current of 141 µA, providing predictable standby and bias current characteristics for system power budgets.
• Ripple Current Performance — Handles 455.6 mA at 120 Hz and 680 mA at 10 kHz, supporting ripple smoothing across both low and high frequency domains.
• Package & Mounting — Radial lead can (φ10 × 12.5 mm) with 5 mm lead spacing for through-hole mounting; shipped in bulk/bag packaging and designated for mass production availability.

Typical Applications

• Automotive Electronics — Power smoothing and decoupling in control modules and sensors where AEC-Q200 qualification and high-temperature operation are required.
• Power Supply Filtering — Bulk energy storage and ripple suppression in DC power rails subject to elevated ambient temperatures.
• Motor Control and Drive Circuits — Decoupling and transient absorption for motor inverters and drive electronics operating under thermal stress.
• Embedded & Industrial Electronics — Long-life filtering in compact through-hole designs where low impedance and predictable leakage are needed.

Unique Advantages

• High-temperature endurance: 2000 hours at +135°C (φ10) provides predictable life performance for hot environments and extended duty cycles.
• Automotive-grade qualification: AEC-Q200 rating and explicit automotive application support integration into vehicle systems with qualification-driven requirements.
• Robust ripple handling: Specified ripple current at both 120 Hz and 10 kHz ensures effective filtering across power-supply frequency ranges.
• Compact through-hole form factor: φ10 × 12.5 mm can with 5 mm lead spacing enables straightforward radial-lead mounting in space-constrained designs.
• Predictable electrical characteristics: Low 100 mOhm impedance, 0.20 tan δ, and defined leakage current (141 µA) simplify circuit modeling and power budgeting.
• Production-ready packaging: Bulk/bag packaging and mass production status support volume assembly and procurement planning.
