UPS1E151MPD

The UPS1E151MPD is a radial-lead aluminum electrolytic capacitor in the Nichicon UPS series, offering a miniature, low-impedance design intended for switching power supply and general-purpose power applications. It provides 150 µF capacitance at a 25 V rating with a compact φ8 × 11.5 mm can and radial leads for through-hole mounting.

Key value propositions include wide operating temperature range (−55 °C to +105 °C), measured low-frequency and high-frequency ripple performance, and a specified 2000-hour endurance at 105 °C—features that support reliable bulk filtering and decoupling in constrained power designs.

Key Features

• Capacitance and Voltage — 150 µF rated capacitance with a 25 V rated voltage and tolerance of −20% to +20% for predictable bulk energy storage.
• Low Loss / Low Impedance — Tangent of loss angle (tan δ) of 0.14 (measured at 20 °C, 120 Hz) and impedance specified at 280 mΩ, aiding in efficient AC ripple handling.
• Ripple Current Capability — Rated ripple currents of 205 mA at 120 Hz (low frequency) and 410 mA at 10 kHz (high frequency) to support filtering of both low- and high-frequency components.
• Reliability & Endurance — 2000 hours endurance at 105 °C (for φD = 8 to 10 mm), with defined limits on capacitance change, tan δ, and leakage current after life testing.
• Wide Temperature Range — Operates from −55 °C to +105 °C to suit demanding thermal environments.
• Compact Radial Package — φ8 × 11.5 mm can size with 3.5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole PCBs that require a small footprint.
• Leakage Current — Specified leakage current of 112.5 µA (measured at 20 °C after 1 minute), consistent with electrolytic capacitor behavior for predictable bias loss.
• Packaging & Availability — Available in bulk (no terminal forming) and bag packing; status listed as mass production. RoHS compliant.

Typical Applications

• Switching power supplies — Designed for use in switching power supplies where a miniature, low-impedance electrolytic capacitor is required.
• General-purpose power filtering — Suitable for general-purpose DC power filtering and smoothing tasks identified in product specifications.
• Compact through-hole assemblies — Radial-lead, small-diameter can fits compact PCB layouts that require reliable bulk capacitance.

Unique Advantages

• Miniature footprint: φ8 × 11.5 mm can minimizes board space while providing 150 µF of capacitance for designs with tight layout constraints.
• Measured low impedance: 280 mΩ impedance and tan δ 0.14 at 20 °C/120 Hz reduce AC losses and improve ripple attenuation in power rails.
• Broad thermal tolerance: −55 °C to +105 °C operating range supports deployment across a wide span of environmental conditions.
• Defined ripple performance: Separate low- and high-frequency ripple current ratings (205 mA @120 Hz and 410 mA @10 kHz) allow designers to assess thermal and ripple handling across expected frequency ranges.
• Endurance-backed reliability: 2000 hours at 105 °C provides an explicit life specification for thermal stress planning and component life budgeting.
• RoHS compliant and production-ready: Mass-production availability and RoHS compliance simplify procurement and regulatory considerations.
