UPJ1H150MDD

The UPJ1H150MDD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UPJ series, designed as a high-reliability, low-impedance option for power electronics. It delivers 15 µF capacitance at a 50 V rating in a compact φ5 × 11 mm package with a 2 mm lead spacing.

This part is suited for general-purpose power filtering and decoupling in compact switching power supply designs and other electronics requiring a polarized, through-hole electrolytic capacitor with defined ripple and leakage characteristics.

Key Features

• Electrical Performance — 15 µF nominal capacitance with ±20% tolerance, rated for 50 V operation; tangent of loss angle (tan δ) specified at 0.1 (measured at 20°C, 120 Hz).
• Ripple Handling — Low-frequency ripple current 36 mA at 120 Hz and high-frequency ripple current 72 mA at 200 kHz, enabling use in both mains-frequency and high-frequency switching circuits.
• Leakage Current — Specified leakage current of 22.5 µA, providing predictable DC leakage performance for bias-sensitive designs.
• Thermal and Lifetime — Rated operating temperature range from −55°C to +105°C with a specified lifetime/endurance of 2000 hours at 105°C.
• Form Factor & Mounting — Radial lead, polarized aluminum can in a φ5 × 11 mm package with 2.0 mm lead spacing (±0.5 mm tolerance); available in bulk or bag packing (no terminal forming).
• RoHS Compliant — Meets RoHS requirements for lead-free environmental compliance.
• Series Characteristics — Part of the UPJ low-impedance series from Nichicon, indicated for switching power supply applications in the series datasheet.

Typical Applications

• Switching Power Supplies — Bulk or local output filtering and smoothing in compact switch-mode converters where low impedance and defined ripple performance are required.
• General-Purpose Power Filtering — Decoupling and smoothing in bench equipment, instrumentation, and consumer electronics that use polarized electrolytic capacitors.
• Compact Power Modules — Where a small φ5 × 11 mm footprint and through-hole radial mounting are preferred for assembly and mechanical retention.

Unique Advantages

• Compact 15 µF / 50 V solution — Provides a moderate capacitance and voltage rating in a small φ5 × 11 mm can, saving PCB space in tight layouts.
• Low-impedance series design — UPJ series characteristics support switching-power environments by reducing AC impedance in the target frequency ranges.
• Measured ripple specifications — Separate low- and high-frequency ripple current ratings (36 mA @120 Hz, 72 mA @200 kHz) give clear guidance for application design and thermal budgeting.
• Wide operating temperature range — −55°C to +105°C rating accommodates designs exposed to significant ambient or operating temperature variation.
• Predictable leakage and loss — Specified leakage current (22.5 µA) and tan δ (0.1 at 20°C, 120 Hz) help ensure predictable behavior in bias-sensitive circuits.
• Through-hole mounting convenience — Radial leads with 2.0 mm spacing (±0.5 mm) simplify placement in conventional PCB designs and prototypes.
