UEP1A221MPD

The UEP1A221MPD is an aluminum electrolytic capacitor from the UEP series offering 220 µF nominal capacitance at a 10 V rated voltage in a bi‑polarized radial can package. It combines compact φ8 × 11.5 mm dimensions with radial leads and 3.5 mm lead spacing for through‑hole mounting in general‑purpose electronics.

Designed for broad operating conditions, the device supports an ambient range of −55°C to 105°C and a rated life of 1000 hours at 105°C, making it suitable for applications that require stable capacitance, defined loss characteristics, and specified ripple handling over long durations.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance at a 10 V rated voltage with ±20% tolerance (120 Hz, 20°C).
• Bi‑Polarized Construction — Specified as Bi‑Polar in the product data for designs that call for bi‑polar capacitor characteristics.
• Electrical Loss (tan δ) — Tangent of loss angle (tan δ) is specified at a maximum of 0.24 for the 10 V rating (measurement frequency 120 Hz, 20°C), enabling predictable loss behavior in designs.
• Leakage Current — Product specification lists a leakage current of 66 µA, stated under the product data conditions.
• Ripple Current Capability — Rated ripple current is 150 mA at low frequency (120 Hz) and 225 mA at high frequency (10 kHz), with frequency coefficients available in the series datasheet.
• Reliability & Lifetime — Endurance defined as 1000 hours at 105°C with polarity inversion every 250 hours, with capacitance and tan δ limits specified after the endurance test.
• Package & Mechanical — Radial lead, can package with φ8 × 11.5 mm dimensions (L: 1.15 cm × D: 0.8 cm) and 3.5 mm lead spacing for straightforward through‑hole assembly.
• Wide Temperature Range — Rated for operation from −55°C to +105°C as specified in the product data.
• Regulatory — RoHS compliant as indicated in the product data.

Typical Applications

• General‑purpose electronic circuits — Use where a 220 µF, 10 V bi‑polar electrolytic capacitor is required for general bulk capacitance and circuit stability in through‑hole assemblies.
• Power supply filtering and decoupling — Specified ripple current ratings (150 mA at 120 Hz; 225 mA at 10 kHz) and capacitance make it applicable for power filtering roles in general‑purpose designs.
• High/low temperature environments — The −55°C to +105°C operating range and 1000 h endurance at 105°C support designs exposed to wide ambient temperature variations.

Unique Advantages

• Bi‑polarized design: Explicitly specified polarization type for designs that require bi‑polar capacitor characteristics.
• Measured loss specification: Clear tan δ limit (0.24 max at 10 V, 120 Hz, 20°C) enables predictable dissipation planning in circuit design.
• Defined ripple performance: Rated ripple currents at both low and high frequencies allow selection based on application frequency content.
• Compact radial package: φ8 × 11.5 mm can and 3.5 mm lead spacing support space‑conscious through‑hole layouts.
• Temperature and endurance data: Rated for −55°C to 105°C with documented 1000‑hour life at 105°C (polarity inversion every 250 hours), providing verifiable long‑term behavior under the specified test conditions.
• RoHS compliant: Meets the RoHS status indicated in the product data for environmentally restricted applications.

Why Choose UEP1A221MPD?
