UPW1A101MDD

The UPW1A101MDD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPW series. It is a radial-lead, polarized capacitor specified at 100 µF and 10 V designed for compact power applications.

Designed for switching power supply applications and automotive electronic systems, this part combines a small footprint (φ5 × 11 mm), AEC-Q200 rating, and a broad operating temperature range to address compact, high-reliability power-filtering needs.

Key Features

• Capacitance & Voltage: 100 µF nominal capacitance at a rated voltage of 10 V with specified tolerance of −20% to +20% for predictable filtering performance.
• Miniature Radial Package: Compact φ5 × 11 mm can with radial lead mounting and 2 mm lead spacing (±0.5 mm) for tight board layouts and through-hole assembly.
• Low impedance characteristics: UPW series design targets low impedance for power applications; specified tangent of loss angle (tanδ) of 0.19 at 120 Hz, 20°C provides a measured dissipation metric.
• Ripple current capability: Rated low-frequency ripple current of 117 mA at 120 Hz and high-frequency ripple current of 180 mA at 10 kHz for handling AC components in power rails.
• Leakage current: Low leakage current specification of 30 µA (measured condition information available in datasheet) to minimize standby losses.
• High-temperature endurance: Qualified for operation from −55°C to +105°C with a specified lifetime/endurance of 2000 hours at 105°C.
• Automotive-grade reliability: AEC-Q200 rating indicating suitability for designs that require component-level automotive qualification.
• Safety feature — pressure relief vent: Radial lead variant includes a pressure relief vent as part of the end-seal design for safer operation under fault conditions.
• Packaging options: Available in bulk (no terminal forming) or bag packing to support different assembly and inventory workflows.

Typical Applications

• Switching power supplies: Designed for decoupling and smoothing in compact switching regulators where low impedance and ripple-current capability are required.
• Automotive electronic systems: AEC-Q200 rating and wide temperature range make it suitable for vehicle electronic modules and control units that demand reliability across temperature extremes.
• Miniature power modules: Small φ5 × 11 mm footprint and radial-lead format fit tight board space in compact power assemblies and module-level designs.

Unique Advantages

• Compact, serviceable form factor: φ5 × 11 mm radial can and 2 mm lead spacing enable space-efficient through-hole placement without sacrificing capacitance.
• Measured dissipation guidance: Specified tanδ (0.19 at 120 Hz, 20°C) gives designers a quantifiable loss parameter for thermal and ripple planning.
• Frequency-aware ripple performance: Distinct ripple current ratings at 120 Hz and 10 kHz support design trade-offs between low- and high-frequency filtering needs.
• Automotive-grade assurance: AEC-Q200 rating supports use in vehicle electronics where component-level certification matters for system reliability.
• Wide operating temperature and endurance: −55°C to +105°C range and 2000 hours at 105°C provide a predictable lifetime envelope for demanding thermal environments.
• Multiple packing choices: Bulk or bag packing options help streamline inventory and assembly handling for different production volumes.
