UBT1E101MPD

The UBT1E101MPD is a radial-lead aluminum electrolytic capacitor designed for high-temperature operation and heavy-duty electronic environments. This polarized can-style capacitor provides 100 µF capacitance at a 25 V rating in a compact φ8 × 11.5 mm package with 3.5 mm lead spacing.

Engineered for demanding applications, the part combines high ripple-current capability, low leakage and a wide operating temperature range (–40°C to +125°C). It is AEC-Q200 qualified and RoHS compliant, making it suitable for automotive and other high-reliability systems requiring stable performance at elevated temperatures.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a rated voltage of 25 V and capacitance tolerance of –20% to +20%.
• High‑Temperature Operation — Rated for operation from –40°C to +125°C with rated endurance specified for +125°C conditions (2000 hours for φ8 bodies at the listed conditions).
• Ripple‑Current Performance — Low-frequency ripple current of 335 mA (120 Hz) and high-frequency ripple current of 500 mA (100 kHz) for power‑smoothing and decoupling tasks.
• Low Leakage & Loss — Specified leakage current of 75 µA and tangent of loss angle (tan δ) of 0.14 measured at 20°C, 120 Hz.
• Package & Mounting — Radial lead, can-style package (φ8 × 11.5 mm) with 3.5 mm lead spacing (±0.5 mm) for through-hole mounting.
• Qualification & Compliance — AEC‑Q200 qualified and RoHS compliant for regulated environments and reliability-focused designs.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing for flexible assembly handling.

Typical Applications

• Automotive electronics — Filter and smoothing capacitor for control modules and power circuits where AEC‑Q200 qualification and high-temperature endurance are required.
• Power supply decoupling — Energy buffering and ripple suppression in DC‑DC converters and onboard power rails operating at elevated temperatures.
• Sensor and actuator power conditioning — Local decoupling and transient suppression for sensors and actuators exposed to harsh thermal environments.

Unique Advantages

• High-temperature endurance: Rated endurance of 2000 hours at +125°C for φ8 sizes provides predictable performance in hot operating environments.
• AEC‑Q200 qualification: Explicit AEC‑Q200 rating supports use in automotive and similarly demanding applications requiring industry-recognized reliability testing.
• Compact, through‑hole form factor: φ8 × 11.5 mm radial can with 3.5 mm lead spacing offers a small footprint for designs needing robust through-hole components.
• Balanced ripple handling: Defined low- and high-frequency ripple current ratings (335 mA @120 Hz, 500 mA @100 kHz) help designers size components for both mains‑frequency and switching power noise.
• Low leakage and controlled dissipation: 75 µA leakage and tan δ = 0.14 (20°C, 120 Hz) support stable biasing and efficient energy storage in power circuits.
• RoHS compliant packaging options: Bulk and bag packing choices simplify inventory and assembly processes while meeting regulatory requirements.
