UHE1J181MPD

The UHE1J181MPD is a miniature, radial‑lead aluminum electrolytic capacitor from Nichicon’s UHE high‑reliability series. It delivers 180 µF at a 63 V rating in a compact φ10 × 20 mm can with 5 mm lead spacing, optimized for space‑constrained through‑hole designs.

Designed for general‑purpose electronic applications, the part combines low impedance and long endurance—specified for 7,000 hours at 105°C—making it suitable where durable, stable bulk capacitance is required across a –40°C to 105°C operating range.

Key Features

• Capacitance & Tolerance — 180 µF with ±20% tolerance (‑20% to +20%), offering defined bulk energy storage for smoothing and filtering.
• Rated Voltage — 63 V DC rating for mid‑voltage power applications.
• Low Loss / Low Impedance — tan δ = 0.09 (120 Hz, 20°C) and specified impedance of 940 mΩ, supporting reduced ripple and improved AC performance.
• Ripple Current Capability — Low‑frequency ripple current 362.6 mA at 120 Hz and high‑frequency ripple current 518 mA at 10 kHz, enabling effective ripple handling across common power frequencies.
• Leakage Current — Specified leakage current of 113.4 µA, useful for predicting standby and leakage behavior in designs.
• Long Endurance — Rated life of 7,000 hours at 105°C (for the 16–100 V range in the UHE series), supporting extended field operation in elevated temperatures.
• Mechanical & Mounting — Radial lead, polar can package (φ10 × 20 mm) with 5.0 mm lead spacing and 0.5 mm spacing tolerance for reliable through‑hole assembly.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible procurement and assembly handling.
• Regulatory — RoHS compliant.

Typical Applications

• General‑purpose electronics — Provides compact, high‑capacitance bulk storage where a 63 V rating and long endurance are required.
• Power supply filtering — Suited for smoothing and ripple reduction in through‑hole power designs thanks to low impedance and specified ripple current ratings.
• Industrial and instrumentation modules — Small footprint and extended temperature range (‑40°C to 105°C) support use in space‑constrained, reliability‑focused assemblies.

Unique Advantages

• Compact high‑capacitance package — 180 µF in a φ10 × 20 mm can conserves PCB space while delivering substantial capacitance.
• Low impedance and defined loss factor — 940 mΩ impedance and tan δ = 0.09 at 120 Hz (20°C) help minimize AC losses and heat under ripple conditions.
• Engineered for long life — 7,000‑hour endurance at 105°C (for the appropriate voltage range) provides predictable long‑term behavior in elevated temperatures.
• Through‑hole reliability — Radial‑lead construction with 5 mm lead spacing simplifies secure mounting and replacement in serviceable designs.
• Clear procurement options — Choice of bulk or bag packing supports small runs and higher‑volume assembly workflows.
• RoHS compliant — Aligns with regulatory requirements for many commercial and industrial projects.
