UKA1A471MPD

The UKA1A471MPD is an aluminum electrolytic capacitor engineered for high‑grade audio equipment. It is a radial‑lead, polarized can‑style capacitor that combines a wide operating temperature range with endurance and low leakage for stable performance in demanding audio and power‑filtering applications.

Key advantages include 470 µF capacitance at 10 V, a −55 °C to +105 °C operating range, AEC‑Q200 qualification, and a 2000‑hour endurance rating at 105 °C—making it suitable for designs that require long life and reliable ripple handling across temperature.

Key Features

• Aluminum electrolytic, radial lead package Polarized radial‑lead can (φ8 × 11.5 mm) for through‑hole mounting and simple PCB integration.
• Capacitance and tolerance 470 µF nominal with ±20% tolerance, suited for bulk decoupling and DC‑link/filtering in audio circuits.
• Rated voltage 10 V rated voltage for low‑voltage audio and power supply applications.
• Wide operating temperature −55 °C to +105 °C operation supports equipment exposed to broad environmental conditions.
• Low leakage current Leakage current specified at 141 µA, supporting low‑noise applications and predictable bias behavior.
• Ripple current capability 280 mA at 120 Hz (low frequency) and 420 mA at 10 kHz (high frequency) for effective smoothing of supply ripple across audio and switching frequencies.
• Long endurance 2000 hours life at 105 °C, offering sustained performance in thermally stressed designs.
• Mechanical dimensions Compact footprint: diameter 8 mm × length 11.5 mm (size dimension L: 1.15 cm × D: 0.8 cm) with 3.5 mm lead spacing (±0.5 mm).
• AEC‑Q200 qualification Automotive‑grade qualification where system level requirements call for AEC‑Q200 components.
• Packaging Supplied in bulk/bag packing for volume assembly or prototyping needs.

Typical Applications

• High‑grade audio amplifiers Used for power supply smoothing and coupling where low leakage and stable capacitance across temperature improve audio fidelity.
• Audio signal and power filtering Provides bulk decoupling and ripple suppression in preamplifiers, DACs, and audio power stages.
• Automotive audio systems AEC‑Q200 qualification and wide temperature range make it suitable for in‑vehicle audio power filtering and decoupling.
• Industrial and consumer electronics Compact can‑style capacitor for board‑level power management in equipment that requires long endurance and robust temperature tolerance.

Unique Advantages

• Designed for audio performance: 470 µF capacitance with low leakage supports clean biasing and stable decoupling in sensitive audio circuits.
• Wide temperature tolerance: −55 °C to +105 °C operation enables deployment in environments with significant thermal variation.
• High ripple handling across frequencies: Specified ripple currents at both 120 Hz and 10 kHz help maintain filter effectiveness for linear and switching sources.
• Long endurance at elevated temperature: 2000 hours at 105 °C provides predictable lifetime behavior for products intended for long service life.
• Compact through‑hole form factor: φ8 × 11.5 mm can with 3.5 mm lead spacing fits space‑constrained PCBs while retaining axial mechanical stability.
• AEC‑Q200 qualified: Offers an additional level of reliability for designs that require automotive‑grade components.
