UHE1J271MPD

The UHE1J271MPD is a radial lead aluminum electrolytic capacitor offering 270 µF capacitance at a 63 V rating in a compact φ10 × 30.5 mm can. It is a polarized, general-purpose capacitor designed for electronic designs that require bulk capacitance with defined ripple current and long-life endurance.

With a wide operating temperature range of –40 °C to 105 °C and a rated endurance of 7000 hours at 105 °C, this part targets applications where sustained performance and predictable ageing are required.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a 63 V rated voltage and capacitance tolerance of –20% to +20%.
• Low Loss (tan δ) — Loss tangent (tan δ) of 0.09 at 20 °C, 120 Hz for the 63 V rating, supporting efficient energy storage with controlled dissipation.
• Ripple Current Capability — Low-frequency ripple current of 518 mA at 120 Hz and high-frequency ripple current of 740 mA at 10 kHz, enabling reliable handling of AC ripple across common power frequencies.
• Leakage Current — Specified leakage current of 170.1 µA (measured as 0.01 × C × V), providing predictable standby loss characteristics.
• Long Life & Temperature Range — Endurance specified at 7000 hours at 105 °C and an operating range from –40 °C to 105 °C for sustained performance under elevated temperature conditions.
• Compact Radial Package — φ10 × 30.5 mm can with 5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole assemblies; available in bulk/bag packaging.
• RoHS Compliant & Production Status — RoHS-compliant construction and listed as in mass production.

Typical Applications

• Power supply filtering — Use the UHE1J271MPD for bulk filtering and smoothing where 270 µF and rated ripple current help stabilize DC rails.
• Decoupling in general-purpose electronics — Suitable for general-purpose boards requiring reliable bulk capacitance and controlled leakage characteristics.
• High-temperature environments — Applications operating up to 105 °C where long endurance (7000 h at 105 °C) is required.

Unique Advantages

• Predictable ripple handling — Specified low- and high-frequency ripple currents (518 mA at 120 Hz, 740 mA at 10 kHz) allow designers to select this part with clear performance targets for AC stress.
• Measured leakage specification — Leakage current given as 170.1 µA (0.01 × C × V) provides a verifiable standby loss figure for power budgeting.
• Compact, serviceable form factor — φ10 × 30.5 mm radial can and 5 mm lead spacing simplify replacement and through-hole assembly in space-constrained designs.
• Long-term thermal endurance — Rated for 7000 hours at 105 °C, enabling predictable lifetime behavior in elevated temperature applications.
• Low dissipation — tan δ of 0.09 at 20 °C, 120 Hz supports lower internal heating and stable performance in AC-biased circuits.
