UBW1E102MHD

The UBW1E102MHD is a radial-lead aluminum electrolytic capacitor offering 1000 µF nominal capacitance at 25 V in a compact φ12.5 × 25 mm can. Engineered for high-temperature operation up to +135°C, this part targets designs that demand long life and stable performance under elevated thermal and ripple stress.

With an AEC-Q200 rating and long-endurance specification, the UBW1E102MHD is positioned for demanding automotive and high-temperature electronic applications where sustained capacitance, low impedance, and robust ripple handling are required.

Key Features

• Capacitance & Rated Voltage — 1000 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance for bulk energy storage and decoupling in compact form factors.
• High-Temperature Endurance — Rated operating temperature range −55°C to +135°C with an endurance life of 3000 hours at 135°C (for φ12.5 series), enabling extended service in hot environments.
• Low Impedance — 33 mΩ impedance supports lower ripple voltage and improved transient performance in power applications.
• Ripple Current Capability — Handles 1.1725 A at 120 Hz (low frequency) and 1.75 A at 10 kHz (high frequency), supporting sustained AC stress on power rails.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.14 measured at 20°C, 120 Hz and 25 V, for predictable dissipation and thermal behavior.
• Leakage Current — Specified leakage current of 750 µA, useful information for standby and low-leakage budgets.
• Mechanical & Packaging — Radial, can-style package φ12.5 × 25 mm with 5.0 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing for flexible procurement and assembly.
• Industry Qualification — AEC-Q200 rated, qualifying the part for use in automotive-grade electronic systems.

Typical Applications

• Automotive Electronics — Suitable for electronic control modules and power electronics that require capacitors rated for +135°C and AEC-Q200 qualification.
• Power Supply Filtering — Designed to handle specified ripple currents (1.1725 A @120 Hz, 1.75 A @10 kHz) for smoothing and decoupling in high-temperature environments.
• High-Temperature Embedded Systems — Long-life specification (3000 hours at 135°C for φ12.5 units) supports designs exposed to prolonged elevated temperatures.

Unique Advantages

• High-temperature capability: Rated to +135°C with defined 3000-hour endurance at that temperature, enabling prolonged operation where thermal margins are limited.
• AEC-Q200 qualification: Provides an industry-recognized baseline for use in automotive and similarly rigorous applications.
• Robust ripple handling: High specified ripple currents at both low and high frequency reduce voltage ripple and thermal stress in power rails.
• Low impedance: 33 mΩ impedance supports improved transient response and reduced ESR-related losses.
• Compact radial package: φ12.5 × 25 mm can with 5 mm lead spacing delivers substantial capacitance in a space-efficient radial-leaded form.
• Controlled dissipation and leakage: tan δ of 0.14 (120 Hz, 20°C) and defined leakage current provide predictable thermal and standby behavior for system-level power budgeting.
