URS1H221MPD

The URS1H221MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s URS series, offering 220 µF capacitance at a 50 V rating in a compact, low-profile φ10 × 12.5 mm can. Designed for general-purpose electronics, it provides defined ripple current capability and endurance for demanding board-level power tasks.

Its polarized radial-lead construction and 5 mm lead spacing make it suitable for through-hole mounting where compact size, reliable power smoothing, and predictable electrical behavior are required across a –40 °C to 85 °C operating range.

Key Features

• Capacitance & Voltage: 220 µF nominal capacitance with a rated voltage of 50 V and tolerance of −20% to +20% for predictable bulk energy storage and filtering.
• Low-profile radial package: Compact φ10 × 12.5 mm can with 5 mm lead spacing and radial leads for through-hole assemblies and dense board layouts.
• Temperature and endurance: Rated for operation from −40 °C to 85 °C with an endurance specification of 2000 hours at 85 °C.
• Ripple current capability: Low-frequency ripple current of 420 mA at 120 Hz and high-frequency ripple current of 630 mA at 10 kHz, supporting smoothing and decoupling needs across common frequencies.
• Electrical loss and leakage: Tangent of loss angle (tan δ) of 0.12 (measured at 20 °C, 120 Hz) and a specified leakage current of 330 µA, enabling controlled dissipation and predictable leakage behavior.
• Polarized construction: Polarized electrolytic design for DC power circuits requiring reliable polarity-aware bulk capacitance.
• Packaging options: Supplied in bulk (no terminal forming) or bag packing for flexible procurement and assembly workflows.

Typical Applications

• General-purpose power supply filtering: Provides bulk capacitance and ripple handling for DC rails in general-purpose electronic equipment.
• Decoupling and smoothing: Used where 220 µF at up to 50 V is required to stabilize voltage rails and reduce ripple across a wide temperature range.
• Through-hole assemblies: Radial lead form factor with 5 mm lead spacing for straightforward insertion into PCBs and prototyping fixtures.

Unique Advantages

• Compact, low-profile footprint: φ10 × 12.5 mm can minimizes board space while retaining substantial capacitance for tight layouts.
• Measured ripple performance: Specified ripple currents at both 120 Hz (420 mA) and 10 kHz (630 mA) provide designers with verifiable AC load capability across frequency ranges.
• Engineered endurance: Endurance rating of 2000 hours at 85 °C gives clear expectations for life performance in elevated-temperature environments.
• Predictable loss and leakage: tan δ of 0.12 and leakage current of 330 µA allow accurate thermal and leakage budgeting in power designs.
• Flexible packing: Available in bulk or bag packing to match manufacturing and procurement preferences.
