The UBW1K101MPD is a radial-lead aluminum electrolytic capacitor offering 100 µF capacitance at an 80 V rating in a compact φ10 × 20 mm can. It is designed for long-life operation in elevated-temperature environments, with an operating range from −55 °C to +135 °C and an endurance specification of 2000 hours at 135 °C.

This part is targeted at power‑electronics and automotive applications where sustained high-temperature performance, reliable ripple handling and compact radial packaging are required.

Key Features

• Electrical Performance — 100 µF capacitance with tolerance −20% to +20%, rated voltage 80 V, and low impedance of 390 mΩ for effective filtering and energy storage.
• Loss Angle (tan δ) — tanδ = 0.08 measured at 20 °C, 120 Hz, supporting predictable AC performance in filtering applications.
• High‑Temperature Endurance — Rated for operation from −55 °C to +135 °C with a rated life of 2000 hours at 135 °C.
• Ripple Current Handling — Supports low-frequency ripple current of 529.3 mA at 120 Hz and high-frequency ripple current of 790 mA at 10 kHz for demanding power conditions.
• Leakage Current — Specified leakage current of 240 µA, enabling predictable standby and bias behavior.
• Radial Packaging — φ10 × 20 mm can with 5 mm lead spacing (±0.5 mm) and radial-lead mounting for through‑hole assemblies; available in bulk or bag packing.
• Automotive Qualification — AEC‑Q200 rating indicating suitability for automotive electronic applications requiring component-level qualification.

Typical Applications

• Automotive Electronics — Energy storage and smoothing in control modules and power systems that require AEC‑Q200 qualified components and extended high-temperature endurance.
• Power Supplies — Bulk filtering and decoupling on DC rails where 80 V rating and low impedance improve transient response and stability.
• Industrial Controls — Decoupling and ripple suppression in controllers and power electronics operating in high ambient temperatures.
• Motor Drives and Actuators — Filtering of drive rails and suppression of ripple currents in compact, through‑hole assemblies.

Unique Advantages

• High‑temperature capability: Rated to +135 °C with 2000 hours endurance, enabling reliable operation in hot environments and longer service life under stress.
• Automotive‑grade qualification: AEC‑Q200 rating supports use in automotive designs that demand proven component-level reliability.
• Strong ripple handling: Specified ripple currents at both low and high frequency (529.3 mA @120 Hz and 790 mA @10 kHz) reduce thermal stress and support dynamic loads.
• Compact radial form factor: φ10 × 20 mm can and 5 mm lead spacing provide a small footprint for through‑hole boards without sacrificing capacitance or voltage rating.
• Predictable leakage and loss characteristics: Leakage current of 240 µA and tanδ of 0.08 at 120 Hz allow for consistent power‑rail behavior and thermal planning.
