UBT1K101MPD

The UBT1K101MPD is a radial-leaded aluminum electrolytic capacitor from Nichicon's UBT series, offering a 100 µF capacitance at an 80 V rating. Engineered for high-temperature operation and dependable endurance, it targets designs that require stable energy storage and ripple handling in compact, through-hole form factors.

With an operating range of −40°C to +125°C and AEC-Q200 qualification, this capacitor is specified for demanding environments where long-term thermal reliability and measurable performance parameters are required.

Key Features

• Capacitance & Tolerance — 100 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C, providing predictable filtering and energy storage.
• Voltage Rating — Rated to 80 V, suitable for circuits that require mid-range DC voltage handling.
• High-temperature Endurance — Rated for operation from −40°C to +125°C with a specified lifetime of 3000 hours at 125°C for the φ10 case size.
• Ripple Current Capability — Low-frequency ripple current of 529.3 mA (120 Hz) and high-frequency ripple current of 790 mA (100 kHz) to support power-supply filtering under varying switching conditions.
• Low Dissipation Factor — tanδ of 0.08 (measured at 20°C, 120 Hz) for controlled AC loss characteristics.
• Leakage Current — Specified leakage current of 240 µA, enabling predictable bias behavior after voltage application.
• Form Factor & Mounting — Radial lead, can-style package with dimensions φ10 × 20 mm and 5 mm lead spacing (±0.5 mm), supplied in bulk/bag packing for through‑hole board assembly.
• Quality & Compliance — AEC-Q200 qualification and RoHS compliance for regulated and automotive-focused applications.
• Polarized Device — Designed for correct polarity installation in DC circuits.

Typical Applications

• Automotive electronics — Use in automotive control modules and power subsystems where AEC-Q200 qualification and +125°C endurance are required.
• High-temperature power supplies — Bulk decoupling and smoothing in power converters operating in elevated ambient temperatures up to +125°C.
• Board-level through-hole assemblies — Compact φ10 can and 5 mm lead spacing make it suitable for space-constrained PCBs that use radial-leaded components.

Unique Advantages

• High-temperature durability: Specified operation to +125°C with a defined 3000-hour life at that temperature for the φ10 case, supporting longer service in thermally demanding environments.
• AEC-Q200 qualified: Provides documented qualification for automotive-grade reliability where applicable.
• Measured ripple performance: Explicit low- and high-frequency ripple current ratings (529.3 mA at 120 Hz, 790 mA at 100 kHz) help designers size capacitors for real-world switching and ripple conditions.
• Predictable electrical loss: Low tanδ (0.08 at 120 Hz, 20°C) offers controlled AC dissipation for stable operation in filter and decoupling roles.
• Compact radial format: φ10 × 20 mm can with 5 mm lead spacing balances small footprint and ease of manual or wave-solder assembly.
• RoHS compliant packaging: Bulk/bag packing options support volume assembly and handling without additional finishes.
