UPT2D181MHD

The UPT2D181MHD is a Nichicon radial lead aluminum electrolytic capacitor specified at 180 µF and 200 V. It is a miniature, polarized can-style capacitor designed for general-purpose power filtering and energy-storage tasks where elevated ripple handling and long life are required.

Key value propositions include high ripple-current capability, long endurance at elevated temperature, and a compact radial-lead package (φ12.5 × 40 mm) with 5 mm lead spacing suitable for through-hole assemblies and bulk/bag packing.

Key Features

• Capacitance & Voltage — 180 µF rated capacitance with a 200 V rated voltage for mid-voltage power applications.
• High Ripple Current — Low-frequency ripple current 700 mA (120 Hz) and high-frequency ripple current 1.12 A (10 kHz), supporting smoothing in both line-frequency and higher-frequency circuits.
• Long Endurance — Rated for 5000 hours at 105°C under DC bias plus rated ripple current, enabling prolonged operation in elevated-temperature environments.
• Thermal Range — Operating temperature range from −40°C to +105°C for broad environmental compatibility.
• Loss and Leakage — Tangent of loss angle (tan δ) 0.12 (measured at 20°C, 120 Hz) and specified leakage current (2 min at 20°C) consistent with electrolytic performance expectations.
• Package & Mounting — Radial lead can, case size φ12.5 × 40 mm, lead spacing 5.0 mm (±0.5 mm), available in Bulk (no terminal forming) or Bag packing for flexible assembly handling.
• Regulatory — RoHS-compliant construction.

Typical Applications

• Lighting Ballasts — Series documentation identifies suitability for ballast applications where high ripple tolerance and compact size are required.
• General Power Filtering — Useful for smoothing and decoupling in general-purpose power supplies and industrial electronics.
• High-Frequency Power Circuits — High-frequency ripple current rating (1.12 A at 10 kHz) supports use in circuits with switching or high-frequency components.

Unique Advantages

• High ripple capability: Specified ripple currents of 700 mA (120 Hz) and 1.12 A (10 kHz) provide margin for both line-frequency and high-frequency smoothing tasks.
• Extended high-temperature life: 5000-hour endurance at 105°C under rated conditions supports longer maintenance intervals and durability in warm operating environments.
• Compact radial package: φ12.5 × 40 mm can with 5 mm lead spacing offers a small footprint for through-hole designs that require reliable electrolytic capacitance.
• Predictable dissipation and leakage: tan δ of 0.12 (120 Hz, 20°C) and specified leakage current provide measurable electrical characteristics for design margin calculations.
• RoHS compliance: Conforms to RoHS requirements for use in lead-free assemblies and regulated markets.
