UPS1H102MHD

The UPS1H102MHD is a miniature, high‑reliability aluminum electrolytic capacitor in a radial‑lead can designed for switching power supplies and general‑purpose power applications. It combines a 1000 µF capacitance with a 50 V rated voltage, low impedance and compact φ16 × 25 mm dimensions for space‑constrained power designs.

Key value propositions include low impedance and high ripple current handling, wide operating temperature range (–55°C to 105°C) and a 3000‑hour endurance rating at 105°C, making it suitable for demanding power filtering and energy‑storage roles in compact electronic systems.

Key Features

• Electrical Performance 1000 µF capacitance at 50 V rated voltage, with capacitance tolerance of −20% to +20% and a tangent of loss angle (tan δ) of 0.1 measured at 20°C, 120 Hz.
• Low Impedance Measured impedance of 58 mΩ (20°C / 100 kHz) supports effective filtering and transient energy delivery in switching environments.
• High Ripple Current Capability Low‑frequency ripple current 1.392 A (120 Hz) and high‑frequency ripple current 1.6 A (10 kHz) enable robust smoothing of switching noise and load transients.
• Thermal and Endurance Ratings Wide operating range from −55°C to +105°C with an endurance rating of 3000 hours at 105°C under rated conditions.
• Leakage and Reliability Specified leakage current of 1500 µA after 1 minute at 20°C, supporting predictable start‑up and steady‑state behavior in power systems.
• Mechanical and Mounting Radial lead package, case size φ16 × 25 mm, lead spacing 7.5 mm (±0.5 mm), supplied bulk or in bags (no terminal forming), for through‑hole mounting on compact PCBs.
• Regulatory RoHS compliant.

Typical Applications

• Switching Power Supplies Designed for smoothing and energy storage in switching power supply outputs and stages where low impedance and high ripple current are required.
• Compact Power Modules Miniature φ16 × 25 mm package allows integration into space‑constrained power modules and small form‑factor converters.
• General‑Purpose Power Filtering Suitable for general‑purpose filtering and decoupling tasks in industrial and electronic equipment that require wide temperature operation and long endurance.

Unique Advantages

• Balanced capacitance and voltage: 1000 µF at 50 V provides a practical energy‑storage solution for mid‑voltage power rails without large board area.
• Low impedance for cleaner rails: 58 mΩ impedance improves ripple attenuation and reduces voltage excursions under dynamic loads.
• High ripple tolerance: Rated ripple currents of 1.392 A (120 Hz) and 1.6 A (10 kHz) handle both low‑ and high‑frequency switching noise.
• Wide temperature and long life: –55°C to 105°C operating range with 3000 hours endurance at 105°C supports reliable operation in elevated‑temperature environments.
• Compact radial package: φ16 × 25 mm can and 7.5 mm lead spacing enable straightforward through‑hole mounting in dense assemblies.
• RoHS compliant: Meets RoHS requirements for restricted substances.
