UPJ1H4R7MDD

The UPJ1H4R7MDD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon's UPJ series, configured as a radial-lead component for through-hole mounting. It delivers 4.7 µF at 50 V with low impedance characteristics suited to power-filtering roles and general-purpose electronics.

Engineered for compact applications, this part combines a wide operating temperature range and defined ripple/ leakage characteristics to support switching power supplies and other small power modules that require stable decoupling and filtering performance.

Key Features

• Capacitance & Rated Voltage — 4.7 µF nominal capacitance with a rated voltage of 50 V and capacitance tolerance of -20% to +20%.
• Low Dissipation Factor — tanδ (DF) = 0.10 measured at 20°C, 120 Hz, providing predictable ESR-related behavior for decoupling and filtering.
• Defined Ripple Handling — Low-frequency ripple current 20 mA (120 Hz) and high-frequency ripple current 40 mA (200 kHz), specified for design of power-supply filters and regulator outputs.
• Controlled Leakage — Leakage current specified at 7.05 µA, enabling predictable bias behavior in DC circuits.
• Temperature & Endurance — Operating temperature range from -55°C to +105°C with rated life/endurance specified as 2000 hours at 105°C.
• Compact Radial Package — Small can size φ5 × 11 mm with 2.0 mm lead spacing (±0.5 mm), radial lead mounting for straightforward through-hole assembly.
• Packaging & Compliance — Available in bulk (no terminal forming) or bag packing; RoHS compliant.

Typical Applications

• Switching Power Supplies — Low impedance and defined ripple current ratings make this capacitor suitable for output filtering and decoupling in compact switching regulators.
• Power Filtering & Decoupling — Small footprint and controlled tanδ support bulk decoupling and local energy storage on control boards and power modules.
• General-Purpose Electronics — Polar radial-lead format and compact size are appropriate for consumer and industrial circuit designs requiring reliable electrolytic capacitance.
• Compact Power Modules — The φ5 × 11 mm can and 2 mm lead spacing enable integration in space-constrained assemblies where through-hole components are preferred.

Unique Advantages

• Predictable electrical behavior: Specified tanδ, leakage current, and capacitance tolerance allow accurate modeling of filter and decoupling networks.
• Compact footprint: φ5 × 11 mm size and 2 mm lead spacing save board area in small-form-factor power designs.
• Wide temperature range: Rated from -55°C to +105°C to support designs that experience broad environmental conditions.
• Defined endurance: 2000 hours at 105°C provides a clear reliability metric for thermal-stressed applications.
• Ease of assembly: Radial lead format and standard lead spacing simplify through-hole placement and soldering operations.
• Regulatory compliance: RoHS compliant material set facilitates use in designs requiring restricted-substance conformity.
