UHW1E151MED

The UHW1E151MED is a radial-lead aluminum electrolytic capacitor in Nichicon’s UHW series, offering 150 µF capacitance at a 25 V rating in a compact φ6.3 × 11 mm can. It combines miniature packaging with design attributes tuned for high ripple-current handling and low high‑frequency impedance.

Designed for general-purpose electronic applications that require robust ripple performance and extended endurance, this part supports operation from −40°C to +105°C and a rated life of 7000 hours at 105°C.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with a tolerance of −20% to +20% and a rated voltage of 25 V.
• Low-frequency and high-frequency ripple capability — Rated ripple currents of 280 mA at 120 Hz and 700 mA at 10 kHz enable effective smoothing and local decoupling under both low- and high-frequency conditions.
• Low dissipation factor — tanδ of 0.13 measured at 20°C, 120 Hz, indicating controlled dielectric losses for the rated voltage and frequency condition.
• Leakage current specification — Typical leakage current of 37.5 µA (equivalent to 0.01CV after 2 minutes at 20°C as defined in the series specification).
• Thermal and lifetime performance — Operating temperature range of −40°C to +105°C with endurance specified at 7000 hours at 105°C, supporting reliable operation in elevated-temperature environments.
• Miniature radial package — Compact dimensions (φ6.3 × 11 mm), radial lead mounting with 2.5 mm lead spacing (±0.5 mm), and available in bulk or bag packing for flexible assembly handling.
• RoHS compliant — Manufactured in compliance with RoHS requirements noted for the UHW series.

Typical Applications

• Power supply filtering — Local bulk and smoothing capacitors on 25 V rails where compact size and high ripple current capability are required.
• Decoupling for compact power electronics — Placement near regulators or power stages to reduce voltage ripple thanks to low high‑frequency impedance and rated ripple currents.
• General-purpose industrial electronics — Board-level energy storage and filtering in designs operating across a wide temperature range (−40°C to +105°C) and requiring long endurance.

Unique Advantages

• High ripple tolerance: Specified ripple currents at 120 Hz and 10 kHz enable the capacitor to handle both mains-frequency and higher-frequency ripple components without excessive heating.
• Compact footprint: φ6.3 × 11 mm radial can provides capacitance density suitable for space-constrained PCB layouts while keeping leaded mounting simplicity.
• Predictable leakage behavior: Leakage current defined as 37.5 µA (0.01CV after 2 minutes at 20°C) makes it straightforward to budget standby and quiescent currents in power budgets.
• Wide operating temperature and defined endurance: −40°C to +105°C operation and 7000 hours at 105°C rating provide a clear reliability envelope for thermal design and lifetime planning.
• Series-level low impedance: The UHW series is characterized by lower impedance at high frequency, helping reduce voltage excursions at switching nodes.

Why Choose UHW1E151MED?

UHW1E151MED positions itself as a compact, high-ripple-capacity aluminum electrolytic solution for engineers needing durable, board-mounted capacitance at 25 V. Its combination of 150 µF capacitance, defined leakage, and frequency-aware ripple ratings makes it suitable for localized power conditioning in space-limited designs.
