UPJ0J122MPD

The UPJ0J122MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPJ series. It is a radial-lead, low-impedance can designed for power filtering and energy storage in compact switching power supplies and general-purpose power electronics.

Key attributes include 1.2 mF capacitance at 6.3 V, a wide operating temperature range from −55°C to +105°C, and a rated endurance of 5000 hours at 105°C—providing stable performance in thermally demanding power applications.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) rated at 6.3 V with capacitance tolerance ±20% for general-purpose bulk decoupling and smoothing.
• Low Impedance / Dissipation — Tangent of loss angle (tanδ) 0.22 measured at 20°C, 120 Hz (6.3 V), supporting efficient AC ripple handling and reduced thermal dissipation.
• High Ripple Current Capability — Low-frequency ripple current 733.9 mA (120 Hz) and high-frequency ripple current 895 mA (200 kHz) to support switching-regulator applications.
• Leakage Current — Specified leakage current of 226.8 µA to aid DC stability in power circuits.
• Robust Endurance — Rated life of 5000 hours at 105°C (φ10 case), delivering long-term reliability under continuous load.
• Compact Radial Can Package — 10 mm diameter × 20 mm length (φ10 × 20L) with 5 mm lead spacing (±0.5 mm), radial-lead mounting for through-hole assembly and secure PCB placement.
• Polarized, RoHS Compliant — Polarized electrolytic design for correct circuit orientation; compliant with RoHS requirements.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible procurement and assembly needs.

Typical Applications

• Switching Power Supplies — Smoothing and output filtering where low impedance and high ripple current handling improve regulator stability and thermal performance.
• DC–DC Converters — Bulk energy storage and decoupling on converter inputs/outputs to reduce voltage ripple during load transients.
• Power Management Modules — Local energy reservoir and transient suppression in compact power modules requiring long endurance at elevated temperatures.

Unique Advantages

• Long High‑Temperature Endurance: 5000 hours at 105°C (φ10 case) supports reliable operation in thermally stressed designs.
• High Ripple Handling: Specified ripple currents at both low and high frequencies help maintain low impedance across switching and DC conditions.
• Compact Footprint: φ10 × 20 mm radial can with 5 mm lead spacing provides a space-efficient through-hole solution for PCB power sections.
• Predictable Loss Characteristics: Tanδ specified at 0.22 (6.3 V, 120 Hz) enables designers to estimate dissipation and thermal behavior accurately.
• Ready for Production: Mass production status and standard packaging choices (bulk/bag) simplify sourcing and assembly logistics.
• Regulatory Compliance: RoHS-compliant construction aligns with environmental requirements for electronic assemblies.
