UEP0J221MPD

The UEP0J221MPD is a bi-polarized aluminum electrolytic capacitor designed for general-purpose electronic applications that require reliable performance across a wide temperature range. It provides 220 µF capacitance at a rated voltage of 6.3 V in a compact radial-can package with radial leads and a 3.5 mm lead spacing.

Engineered for stability from −55°C to +105°C and rated for 1000 hours at 105°C, this capacitor targets designs that need dependable AC-capable decoupling, coupling, and smoothing where polarity can invert during operation.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 6.3 V and a capacitance tolerance of ±20%.
• Bi-Polar Construction — Bi-polarized design suitable for applications where polarity may reverse during operation.
• Wide Temperature Range — Operating range from −55°C to +105°C to support designs exposed to broad thermal conditions.
• Endurance and Reliability — Life rating of 1000 hours at 105°C; endurance test procedure includes polarity inversion every 250 hours as specified in the series datasheet.
• Ripple Performance — Low-frequency ripple current of 150 mA at 120 Hz and high-frequency ripple current of 225 mA at 10 kHz, with a tan δ (DF) of 0.24 measured at 20°C and 120 Hz.
• Leakage Current — Specified leakage current of 41.58 µA.
• Compact Radial Package — Radial can construction with size L: 1.15 × D: 0.8 cm and lead spacing of 3.5 mm; available in bulk/bag packing.
• RoHS Compliant — Conforms to RoHS requirements as indicated in the product data.

Typical Applications

• AC coupling and signal path conditioning — Bi-polarized behavior enables use where signal polarity can invert, useful in audio and analog front-ends requiring stable capacitance.
• Decoupling in bipolar power circuits — Provides bulk decoupling and smoothing for circuits that operate with AC or reversing polarity conditions.
• Industrial and instrumentation electronics — Wide operating temperature range (−55°C to +105°C) and 1000-hour high-temperature endurance support use in sensors and control electronics.
• High-frequency ripple suppression — Rated ripple current performance to 10 kHz (225 mA) supports suppression of high-frequency noise in power rails and switching circuits.

Unique Advantages

• Bi-polar capability: Allows direct use in circuits with reversing polarity without the need for dual-series balancing or additional components.
• Wide thermal envelope: −55°C to +105°C rating expands usable environments from cold storage to elevated-temperature enclosures.
• Proven endurance: 1000-hour life at 105°C with defined polarity inversion test provides a clear, verifiable reliability metric for long-term designs.
• Compact radial form-factor: Small footprint (L: 1.15 × D: 0.8 cm) with 3.5 mm lead spacing balances PCB space efficiency and ease of through-hole assembly.
• Measured electrical characteristics: Specified tan δ, leakage current, and frequency-dependent ripple ratings give engineering teams concrete parameters for margin and thermal budgeting.
• RoHS compliance: Simplifies regulatory planning for environmentally restricted product lines.
