UPJ1H180MDD

The UPJ1H180MDD is a radial-leaded aluminum electrolytic capacitor from Nichicon’s UPJ series, designed for low-impedance power applications. This compact polarized can offers 18 µF capacitance at a 50 V rating, targeted at general-purpose filtering and decoupling in compact power modules and switching power supplies.

With a wide operating temperature range of -55°C to +105°C and a rated endurance of 2000 hours at 105°C, the UPJ1H180MDD provides reliable performance in thermally demanding environments while keeping board footprint small (φ5 × 11 mm / 1.1 × 0.5 cm).

Key Features

• Rated Voltage & Capacitance — 18 µF capacitance at a 50 V rating for DC power rail smoothing and energy storage in compact designs.
• Polarized Radial Lead Package — Radial, can-style package with 2.0 mm lead spacing (±0.5 mm) for through-hole mounting and straightforward PCB placement.
• Temperature & Endurance — Operating temperature range of -55°C to +105°C and life/endurance specified at 2000 hours at 105°C for sustained high-temperature operation.
• Impedance / Loss Characteristics — Specified tangent of loss angle (tanδ) of 0.10 measured at 20°C, 120 Hz, supporting stable performance in AC ripple environments.
• Ripple Current Ratings — Low-frequency ripple current 39.5 mA (120 Hz) and high-frequency ripple current 79 mA (200 kHz), enabling use in both line-frequency and switching-frequency applications.
• Low Leakage — Specified leakage current of 27 µA for controlled DC leakage behavior after voltage application.
• Packaging Options — Supplied in Bulk (no terminal forming) or Bag packing to suit prototype and production ordering preferences.
• RoHS Compliant — Conforms to RoHS requirements for material compliance.

Typical Applications

• Switching Power Supplies — Low-impedance characteristics make it suitable for output filtering and decoupling in compact switching regulators.
• Power Rail Smoothing — Used for DC bus smoothing and transient absorption on intermediate power rails.
• General-Purpose Electronics — Appropriate for consumer and industrial boards requiring through-hole radial capacitors for filtering and energy storage.

Unique Advantages

• Compact Footprint: φ5 × 11 mm can (1.1 × 0.5 cm) saves PCB space in dense board layouts while providing useful capacitance and voltage rating.
• High-Temperature Endurance: Rated for 2000 hours at 105°C, supporting sustained operation in elevated ambient conditions common to power assemblies.
• Frequency Versatility: Defined ripple current values at both 120 Hz and 200 kHz accommodate line-frequency and switching-frequency applications.
• Controlled Loss and Leakage: tanδ = 0.10 and leakage current = 27 µA enable predictable behavior for AC ripple handling and standby conditions.
• Through-Hole Reliability: Radial lead construction with defined lead spacing supports robust solder joints and mechanical stability for field-serviceable designs.
• RoHS Compliance: Material compliance reduces regulatory overhead for regions enforcing restricted substances.
