UBW1K330MPD

The UBW1K330MPD is a radial-lead aluminum electrolytic capacitor offering 33 µF capacitance at an 80 V rating. It is engineered for high-temperature, long-life applications and is available in a compact φ10 × 12.5 mm can with 5 mm lead spacing.

Designed for demanding environments, the UBW1 series provides extended endurance at elevated temperatures and an AEC-Q200 rating, making it suitable where stable filtering and energy storage are required under thermal stress.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a rated voltage of 80 V and a tolerance of ±20% (−20% to +20%).
• High-temperature endurance — Rated operating temperature range from −55 °C to +135 °C with a specified lifetime of 2000 hours at 135 °C.
• Loss and impedance characteristics — Tangent of loss angle (tanδ) of 0.08 at 20 °C, 120 Hz and an impedance of 800 mOhm, supporting stable performance in signal-filtering and decoupling roles.
• Ripple current capability — Low-frequency ripple current of 321.6 mA at 120 Hz and high-frequency ripple current of 480 mA at 10 kHz for effective smoothing under varying load conditions.
• Low leakage — Specified leakage current of 79.2 µA for reliable retention of charge in standby and low-current circuits.
• Package & mounting — Radial, polarized can package (φ10 × 12.5 mm) with 5.0 mm lead spacing; available in bulk (no terminal forming) or bag packing.
• Automotive-oriented qualification — Rated to AEC-Q200, enabling use in automotive electronic designs requiring qualification-level components.
• Identification — Marked with white lettering on a blue sleeve for easy visual identification.

Typical Applications

• Automotive electronic modules — Suitable for electronic control modules and subsystems where AEC-Q200 qualification and extended high-temperature endurance (2000 h at 135 °C) are required.
• High-temperature power filtering — Use in power supply filtering and decoupling in environments that see sustained elevated temperatures, leveraging the −55 °C to +135 °C operating range.
• Long-life systems — Applications that demand long-term stability and low leakage over extended service life, benefitting from the specified leakage and endurance figures.

Unique Advantages

• Proven high-temperature performance: Endurance specified at 2000 hours at 135 °C provides quantifiable reliability for thermal stress conditions.
• Automotive qualification: AEC-Q200 rating supports design validation and procurement for qualified automotive electronic assemblies.
• Compact radial can: φ10 × 12.5 mm footprint with 5 mm lead spacing delivers a small form factor for space-constrained assemblies.
• Balanced electrical characteristics: Low tanδ (0.08) and 800 mOhm impedance give stable filtering performance across typical operating conditions.
• Effective ripple handling: Specified ripple currents at both low and high frequencies (321.6 mA at 120 Hz; 480 mA at 10 kHz) support applications with mixed-frequency loading.
• Low leakage current: 79.2 µA leakage supports charge retention and low-standby dissipation requirements.
