UPW1H102MHD

The UPW1H102MHD is a miniature, high-reliability aluminum electrolytic capacitor in the Nichicon UPW series, configured as a radial-lead can. It delivers 1000 µF capacitance at a 50 V rating with a low-impedance design suited for demanding power applications.

Designed for use in switching power supplies and automotive electronics, the part combines high ripple-handling capability, long endurance at elevated temperature, and polarized radial-lead packaging for through-hole power designs and module assemblies.

Key Features

• Capacitance & Voltage — 1000 µF (1 mF) nominal capacitance with a 50 V rated voltage and ±20% tolerance, providing bulk energy storage for DC power rails.
• Low Impedance — Specified impedance of 68 mΩ to support low-loss smoothing and decoupling in power circuits.
• High Ripple Current Capability — Rated ripple current of 1.676 A at 120 Hz and 2.235 A at 10 kHz, enabling effective filtering across low and high switching frequencies.
• High Reliability Endurance — 8000 hours rated life at 105°C, with leakage current specified at 1500 µA, designed for extended operation in elevated temperature environments.
• Wide Temperature Range — Operating range from −55°C to +105°C to accommodate harsh thermal conditions.
• Radial Lead Package — φ16 × 25L can with 7.5 mm lead spacing (±0.5 mm) and radial-lead mounting for through-hole assembly; available in bulk or bag packing.
• AEC-Q200 Rating — Rated per AEC-Q200, suitable for automotive electronic applications requiring component-level qualification.

Typical Applications

• Switching Power Supplies — Bulk decoupling and output smoothing where low impedance and high ripple capability improve regulation and transient response.
• Automotive Electronics — Power filtering and energy storage in automotive modules, supported by AEC-Q200 rating and operation to +105°C.
• Power Modules and Industrial Electronics — High-reliability bulk capacitance for DC power rails in modules that demand long endurance and elevated-temperature operation.

Unique Advantages

• High Endurance at Elevated Temperature — 8000 hours at 105°C provides predictable aging characteristics for designs with long life requirements.
• Wide Thermal Operating Range — −55°C to +105°C rating supports deployment across a broad set of environmental conditions.
• Strong Ripple Handling Across Frequencies — Specified ripple currents at both 120 Hz and 10 kHz make the part versatile for low-frequency and high-frequency switching environments.
