UPS2W4R7MHD

The UPS2W4R7MHD is a miniature, low-impedance aluminum electrolytic capacitor designed for switching power supplies and general-purpose power filtering. It is a polarized, radial-lead can with a compact footprint and a high rated voltage for demanding DC applications.

With a rated capacitance of 4.7 µF at 450 V and RoHS compliance, this part targets designers who need a compact high-voltage electrolytic solution with defined ripple-handling and thermal endurance characteristics.

Key Features

• Capacitance & Voltage: 4.7 µF capacitance with a 450 V rated voltage, suitable for high-voltage DC filtering and decoupling in power stages.
• Low Impedance Design: Specified as a low-impedance type for switching power supplies, helping reduce ripple and improve regulation in switching circuits.
• Polarized Radial-Lead Package: Polarized aluminum electrolytic in a radial, can-style package with 5 mm lead spacing for through-hole mounting and robust connections.
• Temperature & Endurance: Operating range −25 °C to +105 °C with a rated lifetime of 3000 hours at 105 °C under rated conditions.
• Ripple Current Capability: Rated ripple currents include 49 mA at 120 Hz and 78.4 mA at 10 kHz, helping to quantify AC stress handling in actual designs.
• Tolerance: Capacitance tolerance of ±20% (−20% to +20%) at 120 Hz, 20 °C for predictable circuit performance.
• Compact Footprint: Small physical size (approximately 2.0 cm × 1.25 cm) for space-constrained PCB layouts.
• RoHS Compliant: Conforms to RoHS directives, supporting environmental compliance requirements.

Typical Applications

• Switching Power Supplies: Used for output filtering and decoupling where low impedance and high voltage rating are required to stabilize regulation and reduce ripple.
• High-Voltage DC Filtering: Suitable for bulk or local filtering in high-voltage DC circuits thanks to its 450 V rating and defined ripple-current characteristics.
• General-Purpose Power Smoothing: Employed in general-purpose power circuits to provide energy storage and transient smoothing in compact through-hole assemblies.
• Through-Hole Power Modules: Radial-lead configuration makes it suitable for robust mounting in power modules and PCB assemblies that require traditional through-hole components.

Unique Advantages

• High-Voltage in a Small Package: Delivers 4.7 µF at 450 V in a compact can, enabling designers to meet voltage requirements without large form factors.
• Quantified Ripple Performance: Published ripple-current values at 120 Hz and 10 kHz allow accurate thermal and lifetime assessments in switching environments.
• Specified Endurance: 3000 hours at 105 °C provides a clear reliability target for thermal-stressed designs and helps with lifetime budgeting.
• Easy Through-Hole Integration: Radial-lead, polarized can format with 5 mm lead spacing simplifies placement and soldering in conventional PCB workflows.
• Regulatory Compliance: RoHS conformity supports inclusion in products that require restricted-substance compliance.
