UHW1E152MHD

The UHW1E152MHD is a Nichicon UHW series miniature aluminum electrolytic capacitor in a radial-lead can. It is a high-reliability, polarized capacitor offering 1500 µF capacitance at a 25 V rating with compact dimensions (φ12.5 × 20 mm).

Designed for general-purpose electronics that require high ripple-handling in a small footprint, the UHW1E152MHD combines low impedance, long endurance at elevated temperature, and a wide operating range to support demanding assemblies and assemblies with space constraints.

Key Features

• Capacitance & Voltage — 1500 µF (1.5 mF) nominal capacitance with a rated voltage of 25 V and tolerance of −20% to +20%.
• High ripple-current capability — Rated low-frequency ripple current of 1.56 A at 120 Hz and high-frequency ripple current of 2.6 A at 10 kHz, supporting designs with significant AC stress.
• Low impedance — Impedance specified at 51 mOhm and a tangent of loss angle (tanδ) of 0.13 (measured at 20°C, 120 Hz), enabling effective filtering and decoupling in compact circuits.
• Long endurance — 10,000 hours life specified at 105°C, providing stable performance over extended high-temperature operation.
• Wide operating temperature — Rated for −40°C to +105°C to accommodate a broad range of environmental conditions.
• Radial lead package — φ12.5 mm can, 20 mm length, 5 mm lead spacing (±0.5 mm), polar radial-lead format for through-hole mounting and straightforward assembly.
• Leakage and stability — Leakage current of 375 µA and specified limits on capacitance change and tanδ after endurance testing to ensure predictable behavior over life.
• RoHS compliant — Meets RoHS directive requirements as indicated in the product information.
• Packaging options — Available in bulk (no terminal forming) or bag packing to suit production and prototyping needs.

Typical Applications

• General-purpose electronics — Suited for circuits where reliable bulk capacitance and ripple handling are required in a compact radial-lead package.
• High-ripple circuits — Effective in assemblies that experience significant AC ripple, leveraging its rated 1.56 A (120 Hz) and 2.6 A (10 kHz) ripple currents.
• High-temperature environments — Appropriate for designs that operate continuously at elevated temperatures up to 105°C, given its 10,000-hour endurance rating.
• Through-hole assemblies — Radial-lead form and 5 mm lead spacing simplify through-hole placement and mechanical mounting in compact layouts.

Unique Advantages

• High ripple capacity: Supports substantial low- and high-frequency ripple currents (1.56 A at 120 Hz; 2.6 A at 10 kHz), reducing core heating impact in ripple-heavy circuits.
• Compact footprint: φ12.5 × 20 mm can size with 5 mm lead spacing delivers 1500 µF in a small radial-lead package for space-constrained designs.
• Low impedance and controlled losses: 51 mOhm impedance and tanδ of 0.13 (20°C, 120 Hz) help improve filtering performance and stability in power networks.
• Proven endurance at temperature: 10,000 hours at 105°C provides predictable long-term behavior in elevated-temperature applications.
• Predictable leakage and tolerance: Specified leakage current (375 µA) and ±20% capacitance tolerance enable straightforward component selection and margining.
• Regulatory compliance: RoHS-compliant construction supports environmental and regulatory requirements.
