UPJ1A122MHD6

The UPJ1A122MHD6 is a radial-lead aluminum electrolytic capacitor in the Nichicon UPJ series, offering 1.2 mF capacitance at a 10 V rating. Designed for general-purpose and power circuitry, it combines low impedance and long life characteristics intended for applications such as switching power supplies and power filtering.

This part delivers high ripple-handling capability and a wide operating temperature range of -55°C to +105°C, with a rated endurance of 5000 hours at 105°C, packaged for bulk or bag packing.

Key Features

• Capacitance & Voltage: 1.2 mF (1200 µF) nominal capacitance with a rated voltage of 10 V and tolerance of ±20% at 120 Hz, 20°C.
• Low Loss Factor: tanδ (DF) 0.19 measured at 20°C, 120 Hz, 10 V, supporting efficient decoupling and filtering in power circuits.
• High Ripple Current Capability: 762.6 mA at 120 Hz (low frequency) and 930 mA at 200 kHz (high frequency) for effective smoothing in switching environments.
• Long Endurance: Rated for 5000 hours at +105°C under rated ripple/current conditions, supporting sustained operation in elevated-temperature systems.
• Compact Radial Can Package: Aluminum can, radial lead mounting with φ12.5 mm diameter and 15 mm length (φ12.5×15L), lead spacing 5.0 mm (±0.5 mm).
• Leakage Current: Specified leakage of 360 µA, suitable for circuits where controlled leakage is required.
• Polarized, Through-Hole Mounting: Radial lead, polarized construction for straightforward through-hole PCB implementation.
• RoHS Compliant: Meets RoHS directive requirements for restricted substances.

Typical Applications

• Switching Power Supplies: Low impedance and high ripple current capability make it suitable for input/output filtering and smoothing in switch-mode power supplies.
• Power Filtering & Decoupling: Bulk energy storage and decoupling for DC rails in general-purpose electronic equipment.
• Embedded Power Modules: Compact radial package for use in power modules and PCB-mounted power subsystems that require sustained operation up to +105°C.

Unique Advantages

• High ripple handling: Dual-spec ripple ratings at low and high frequency give designers measurable performance for both 120 Hz and switching-frequency environments.
• Extended high-temperature life: 5000 hours at 105°C provides predictable endurance for designs exposed to elevated ambient temperatures.
• Low dissipation factor: tanδ of 0.19 at 10 V reduces loss in AC conditions, improving overall power efficiency in filtering applications.
• Compact through-hole form factor: φ12.5×15 mm can size with 5.0 mm lead spacing offers a small footprint for PCB layouts while retaining through-hole robustness.
• Stable leakage specification: Defined leakage current (360 µA) supports predictable bias behavior in power and backup circuits.
• Regulatory compliance: RoHS compliance supports environmental and regulatory requirements for electronic assemblies.
