UBT1A102MPD

The UBT1A102MPD is a radial-lead aluminum electrolytic capacitor with a capacitance of 1000 µF and a rated voltage of 10 V. It is designed for applications that require high-temperature endurance and robust ripple handling in a compact φ10 × 20 mm package.

With an operating temperature range from −40°C to +125°C, AEC‑Q200 qualification, and a specified endurance of 5000 hours at 125°C, this capacitor is targeted at demanding electronics systems where sustained performance at elevated temperatures is required.

Key Features

• Capacitance & Tolerance — 1000 µF nominal with ±20% tolerance at 120 Hz, 20°C for bulk energy storage and smoothing applications.
• Rated Voltage — 10 V DC rating suitable for low-voltage power rails and post-regulation filtering.
• High‑Temperature Endurance — Rated for operation from −40°C to +125°C with a life specification of 5000 hours at 125°C.
• Ripple Current Capability — 737 mA at 120 Hz (low frequency) and 1.1 A at 100 kHz (high frequency) to support high ripple and switching regulator outputs.
• Leakage Current — Specified leakage current of 300 µA, supporting predictable power loss and system bias planning.
• Package & Mounting — Radial can package (φ10 × 20 mm) with 5 mm lead spacing (±0.5 mm) for through‑hole mounting; available in Bulk (no terminal forming) or bag packing.
• Reliability & Qualification — AEC‑Q200 qualified and RoHS compliant, aligning with industry reliability and environmental requirements.

Typical Applications

• Automotive Electronics — Bulk filtering and decoupling on low‑voltage automotive power rails where AEC‑Q200 qualification and high temperature endurance are required.
• DC–DC Converter Output Filtering — Smoothing and energy buffering on regulator outputs benefiting from the 1000 µF capacitance and high ripple current capability.
• Power Supply Smoothing — Bulk energy storage and ripple suppression in industrial and embedded power supplies operating up to +125°C.
• Infotainment & Control Modules — Low‑voltage decoupling and transient absorption in modules that demand stable performance across −40°C to +125°C.

Unique Advantages

• High temperature endurance: 5000 hours at 125°C provides predictable lifetime performance in thermally stressed environments.
• Strong ripple handling: Dual-spec ripple ratings (737 mA @120 Hz, 1.1 A @100 kHz) make it suitable for both linear and switching power stages.
• Compact, through‑hole form factor: φ10 × 20 mm radial can with 5 mm lead spacing balances board space and capacitance for legacy and mechanically robust designs.
• Automotive‑grade qualification: AEC‑Q200 rating and RoHS compliance support deployment in regulated and reliability-focused designs.
• Predictable leakage characteristics: Specified leakage current (300 µA) aids in power budgeting and system stability calculations.
