UPS2A151MHD

The UPS2A151MHD is a miniature, low‑impedance aluminum electrolytic capacitor designed for switching power supplies and general-purpose power electronics. It provides 150 µF of capacitance at a 100 V rating in a compact radial‑lead can.

Engineered for demanding operating conditions, the part combines a wide temperature range (–55 °C to 105 °C) with a rated endurance of 3000 hours at 105 °C, delivering dependable bulk capacitance and ripple handling for space‑constrained power designs.

Key Features

• Electrical Performance – 150 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance, suitable for higher‑voltage power rails.
• Low Impedance & Ripple Capability – Low impedance (130 mΩ) with specified ripple currents of 355 mA at 100 kHz and 710 mA at 10 kHz for effective ripple suppression in switching supplies.
• Temperature & Endurance – Wide operating temperature range from –55 °C to 105 °C and qualified for 3000 hours at 105 °C under rated conditions.
• Package & Mounting – Radial lead can with 5 mm lead spacing; compact dimensions L: 2.5 × D: 1.25 cm and a seated height maximum of 2.5 cm for tight layouts.
• Polarized Design – Polarized aluminum electrolytic construction for bulk energy storage and smoothing applications.
• Environmental Compliance – RoHS compliant per the provided product information.

Typical Applications

• Switching Power Supplies – Bulk capacitance and low impedance help reduce output ripple and improve regulator stability in switching converters.
• General‑Purpose Power Filtering – Suitable for decoupling and smoothing on higher‑voltage rails where 100 V rating is required.
• Temperature‑Challenging Electronics – Wide operating temperature range and long endurance make it appropriate for designs exposed to broad thermal environments.

Unique Advantages

• Low impedance for effective ripple control: 130 mΩ impedance and defined ripple current ratings enable predictable performance in switching environments.
• High voltage capability: 100 V rating allows use on elevated DC rails without up‑rating multiple lower‑voltage capacitors.
• Compact, board‑friendly package: Small can size (L: 2.5 × D: 1.25 cm) and 5 mm lead spacing minimize PCB footprint in space‑constrained designs.
• Wide temperature range with proven endurance: –55 °C to 105 °C operating range and 3000 hours at 105 °C support long‑term reliability under thermal stress.
• Standards‑oriented compliance: RoHS conformity supports regulatory and environmental requirements.
