UHD1E331MPD6

The UHD1E331MPD6 is a radial-lead aluminum electrolytic capacitor designed for general-purpose power applications requiring bulk capacitance and high ripple handling. It features a 330 µF capacitance at 25 V in a compact φ10 × 12.5 mm can with 5 mm lead spacing.

Built on the UHD series’ high-ripple, low-impedance architecture, this part targets power-smoothing, decoupling and regulator applications where elevated operating temperature, predictable endurance and measurable leakage/ dissipation characteristics are important.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance rated at 25 V with tolerance −20% to +20% (measured at 120 Hz, 20°C).
• Radial lead package — φ10 × 12.5 mm can with 5 mm lead spacing (lead spacing tolerance ±0.5 mm); available in bulk (no terminal forming) or bag packing.
• High ripple capability / low impedance — Low-frequency ripple current 721 mA (120 Hz) and high-frequency ripple current 1.03 A (100 kHz), combined with the UHD series’ lower impedance at high frequency.
• Endurance & temperature range — Specified lifetime of 4000 hours at 105°C and operating temperature range −40°C to +105°C.
• Controlled dissipation & leakage — Tangent of loss angle (tan δ) 0.14 at 20°C, 120 Hz, and measured leakage current of 82.5 µA.
• RoHS compliant & production ready — Conforms to RoHS requirements and listed as mass production status.

Typical Applications

• Power supply smoothing — Bulk energy storage and output filtering for linear supplies and post-regulator stages using the 330 µF capacitance and rated ripple capability.
• Switching regulator decoupling — Supports high-frequency decoupling at switching nodes, leveraging the UHD series’ lower impedance at high frequency and 1.03 A ripple rating at 100 kHz.
• Industrial and embedded electronics — Suitable for designs that require operation across −40°C to +105°C and predictable endurance of 4000 hours at elevated temperature.
• General-purpose electronic assemblies — Radial-lead format and compact φ10 × 12.5 mm size simplify retrofits and through-hole PCB designs requiring reliable bulk capacitance.

Unique Advantages

• Measured ripple performance: Explicit ripple current specifications at both low (721 mA at 120 Hz) and high frequency (1.03 A at 100 kHz) let you size capacitors deterministically for real-world switching and line conditions.
• High-frequency optimized: Series-level low-impedance behavior at high frequency improves decoupling effectiveness in switching applications.
• Compact radial form factor: φ10 × 12.5 mm can and 5 mm lead spacing provide a small footprint for through-hole boards while retaining robust capacitance.
• Predictable loss and leakage: Specified tan δ (0.14 at 20°C, 120 Hz) and leakage current (82.5 µA) help ensure stable performance over life and simplify thermal/power budgeting.
• Designed for elevated-temperature service: 4000 hours endurance at 105°C supports long-term operation in hotter environments common to industrial and power applications.

Why Choose UHD1E331MPD6?

The UHD1E331MPD6 combines a practical 330 µF/25 V electrical profile with the UHD series’ emphasis on low impedance at high frequency and robust ripple handling. Its compact radial can and defined leakage/tan δ values make it straightforward to integrate into through-hole power and regulator designs where predictable thermal and electrical behavior matters.

This part is well suited to engineers and buyers specifying reliable bulk capacitance for switching power supplies, regulator outputs and general-purpose industrial electronics that must operate across −40°C to +105°C and sustain long-term elevated-temperature endurance.
