• Low Impedance Design — Part of the UPJ series characterized for low impedance behavior, making it suitable for switching power supply use.
• Ripple Current Capability — Handles 1.386 A at 120 Hz (low frequency) and 1.54 A at 200 kHz (high frequency), supporting high ripple environments.
• Loss Tangent — Measured tanδ of 0.26 at 20°C, 120 Hz, enabling designers to assess equivalent series characteristics for filtering and stability.
• Leakage Current — Specified leakage current of 737.1 µA, useful for standby and bias current budgeting.
• Endurance & Temperature — Rated life of 5000 hours at 105°C with operating temperature range from −55°C to +105°C.
• Package & Mounting — Radial-lead can format, physical size φ16 × 20L mm, lead spacing 7.5 mm (±0.5 mm) for through-hole board layouts.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible procurement and assembly handling.
• Regulatory — RoHS compliant.

Typical Applications

• Switching Power Supplies — Low impedance and high ripple-current capability make this capacitor well suited for output smoothing and bulk decoupling in switching regulators.
• General-Purpose Electronics — Suitable for a wide range of general-purpose power applications where a 6.3 V, high-capacitance radial electrolytic is required.
• Elevated-Temperature Deployments — With 5000 hours endurance at 105°C, it is appropriate for designs that must maintain performance under prolonged thermal stress.

Unique Advantages

• Optimized for Switching Supplies: Low-impedance UPJ series design targets the needs of switching power stages where transient current handling matters.
• High Ripple Performance: Specified ripple currents at both 120 Hz and 200 kHz provide confidence for both mains-frequency and high-frequency converter environments.
• Extended High-Temperature Life: 5000-hour endurance at 105°C supports long-term reliability in higher-temperature applications.
• Compact Radial Can: φ16 × 20 mm can and 7.5 mm lead spacing enable compact through-hole layouts without sacrificing capacitance.
• Clear Electrical Parameters: Documented tanδ, leakage current, and tolerance make it straightforward to model in power and analog designs.
• RoHS Compliant: Meets RoHS requirements for restricted substance compliance.
