UPS2W2R2MPD

The UPS2W2R2MPD is a miniature, low-impedance aluminum electrolytic capacitor designed for switching power supplies and general-purpose power filtering. This radial-lead, polarized can delivers 2.2 µF capacitance at a 450 V rating in a compact package optimized for space-constrained power electronics.

Engineered for broad operating conditions, the part supports an operating temperature range from −25 °C to 105 °C and offers defined ripple-current handling and endurance for demanding DC-bias and ripple environments.

Key Features

• Capacitance & Voltage: 2.2 µF capacitance rated at 450 V, suitable for high-voltage filtering and energy-storage roles in power designs.
• Miniature Radial Package: Radial, can-style package with 5 mm lead spacing and compact dimensions (L: 2 cm × D: 1 cm) for tight PCB layouts and through-hole assembly.
• Wide Operating Temperature: Specified for −25 °C to 105 °C operation to cover a broad range of thermal environments.
• Low Impedance & Ripple Capability: Specified ripple-current values of 29 mA at 120 Hz and 46.4 mA at 10 kHz provide measurable ripple handling for switching applications.
• Endurance: Lifetime specified at 2000 hours at 105 °C, enabling reliability under elevated-temperature stress.
• Polarized, ±20% Tolerance: Polarized aluminum electrolytic construction with capacitance tolerance of −20% to +20% for predictable circuit behavior.
• RoHS Compliant: Conforms to RoHS directives, supporting environmental compliance requirements.

Typical Applications

• Switching Power Supplies: Bulk and decoupling capacitor for high-voltage stages and post-rectification smoothing in compact SMPS modules.
• Power Filtering in Industrial Electronics: Local energy storage and ripple suppression in control and power conversion circuits operating up to 105 °C.
• General Purpose Power Circuits: Through-hole installations where a high-voltage, compact electrolytic capacitor is required for energy buffering and filtering.

Unique Advantages

• High DC Voltage Capability: 450 V rating allows use in higher-voltage power designs without stacking or additional series components.
• Space-Saving Form Factor: Compact dimensions (2 cm × 1 cm) and 5 mm lead spacing minimize PCB area while keeping through-hole mounting simplicity.
• Defined Ripple Performance: Published ripple-current values at 120 Hz and 10 kHz let designers size thermal and ripple budgets with confidence.
• Rated Endurance at Elevated Temperature: 2000 hours at 105 °C provides a clear expectation of life under sustained high-temperature operation.
• Regulatory Compliance: RoHS compliance supports environmentally constrained product development and manufacturing.
