ULD1E151MPD

The ULD1E151MPD is a radial-lead aluminum electrolytic capacitor designed for general-purpose power applications. As a miniature, long-life device in Nichicon's ULD series, it combines a 150 µF capacitance with a 25 V rating and is optimized for roles like power-supply smoothing and decoupling in electronics.

Key performance attributes include an extended endurance rating of 10000 hours at 105°C, a wide operating temperature range from −40°C to +105°C, and measurable ripple current capability across low and high frequencies—making it suitable for sustained operation in demanding thermal environments.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with a rated voltage of 25 V and a capacitance tolerance of −20% to +20%.
• Long-life Endurance — Rated for 10000 hours at 105°C under DC bias plus rated ripple current, supporting long-term reliability in powered applications.
• Ripple Handling — Low-frequency ripple current of 231 mA at 120 Hz and high-frequency ripple current of 330 mA at 100 kHz to support smoothing and filtering tasks across frequency ranges.
• Low Loss & Leakage — Specified tangent of loss angle (tan δ) of 0.3 (measured at 20°C, 120 Hz) and a leakage current of 37.5 µA for controlled dissipation and low standby leakage.
• Thermal Range — Operating temperature range from −40°C to +105°C for deployment in both cold-start and elevated-temperature environments.
• Compact Radial Can — Miniature can package with dimensions φ8 × 11.5 mm and radial lead spacing of 3.5 mm (lead spacing tolerance ±0.5 mm) for through-hole mounting where board space is limited.
• Packaging Options — Available in bulk (no terminal forming) and bag packing to suit different assembly and handling workflows.
• Environmental Compliance — RoHS compliant.

Typical Applications

• LED lighting power supplies — Provides bulk capacitance and ripple smoothing for LED driver circuits, leveraging long-life endurance at elevated temperature.
• General-purpose power supplies — Acts as a filter/smoothing capacitor on DC rails in consumer and industrial electronics.
• Embedded and control electronics — Used for decoupling and energy storage in compact through-hole designs that require radial-lead components.

Unique Advantages

• Extended thermal endurance — 10000-hour rating at 105°C supports sustained operation in high-temperature applications and enhances system reliability.
• Broad ripple capability — Specified ripple current at both low (120 Hz) and high (100 kHz) frequencies helps designers address filtering needs across switching and line-frequency domains.
• Compact footprint — φ8 × 11.5 mm can size and 3.5 mm lead spacing enable integration into space-constrained through-hole layouts.
• Controlled loss and leakage — tan δ = 0.3 and specified leakage current provide predictable dissipation and standby characteristics for power-sensitive designs.
• RoHS compliance — Meets environmental regulatory requirements for lead-free assembly processes.
• Flexible procurement — Bulk and bag packing options accommodate both prototyping and production handling preferences.
